We encourage everyone to register and attend our summit from our website, zscaler.com/zenithlive Now I'll turn the call over to Jay.

Thank you, Bill. As you saw in our earnings release, we delivered outstanding results for the third quarter, with accelerating growth at scale while increasing adoption of our broader platform. We drove 60% growth in revenue and 71% growth in billings. We also generated strong growth in operating profits and delivered record free cash flow. Enterprises are looking to Zscaler to secure their digital transformation and architect for the work-from-anywhere economy, which we believe is the new normal. Our results exceeded our expectations, and we are again increasing our guidance for fiscal ‘21. Our business is firing on all cylinders. Our superior architecture and optimized go-to-market engine is elevating us above the competitive noise. Our Zero Trust Exchange platform connects users, devices and applications, which is fundamentally different from firewall-based castle-and-moat security. Our platform prevents lateral threat movement and eliminates the attack surface by making applications invisible from the Internet, hence reducing business risk. Furthermore, our proxy architecture, designed to inspect SSL-encrypted traffic, blocks sophisticated threats and prevents loss of sensitive data. Faced with the latest news-making ransomware and other cyberattacks, CISOs and CIOs are turning to Zscaler to dramatically improve their security posture while reducing their legacy IT costs. As you have heard me say before, architecture matters. Zscaler purpose built the right high-performance, multi-tenant proxy architecture from day one, whereas many vendors are trying to retrofit their existing solutions, which inevitably fails. Built from the start to enforce policy at the edge, as advocated by SASE framework, we are deployed across 150 data centers with five nines of availability. We are processing more than 160 billion transactions daily, preventing up to 7 billion security incidents and policy violations. This unmatched network effect provides better security and user experience. Let me highlight 3 factors that drove our strong performance…

Thank you, Jay. As Jay mentioned, we are pleased with the results for the third quarter of 2021. Revenue for the quarter was $176.4 million, up 12% sequentially and 60% year-over-year. ZPA product revenue was 16% of total revenue. From a geographic perspective, we had broad strength across our three major regions: Americas represented 51% of revenue, EMEA was 38% and APJ was 11%. Turning to calculated billings, which we define as the change in deferred revenue for the quarter plus total revenue recognized in that quarter. Billings grew 71% year-over-year to $225 million, with billing duration towards the upper-end of our 10 to 14 months range. We had several customers choosing to pay upfront for their multi-year contracts. As a reminder, our contract terms are typically one to three years and we do not offer any special incentives for upfront payments. With that in mind, we are also pleased that short-term billings, which are calculated based on the change in short-term deferred revenue plus reported revenue for the period, grew 61% over the prior year. Remaining performance obligations, or RPO, which represent our total committed non-cancelable future revenue, were $1.2 billion as of April 30th. RPO grew 85% from one year ago. The current RPO is 51% of the total RPO. Our strong customer retention and ability to upsell the broader platform have resulted in a consistently high dollar-based net retention rate, which was 126% compared to 127% last quarter and 119% a year ago. As we have highlighted, this metric will vary quarter-to-quarter. While good for our business, our increased success selling bigger bundles and selling multiple-pillars from the start and faster upsells within a year can reduce our dollar-based net retention rate in the future. Considering these factors, we feel that 126% is outstanding. Total gross margin…

[Operator Instructions]. Our first question or comment comes from the line of Alex Henderson.

First off, let me thank you for a superb quarter. Outstanding results. And the question I have is really on the sales capacity you've been adding over the last year. To what extent do you see that capacity now maturing in terms of its productivity? And how do you think about additional continuation of that incredibly successful program?

Alex, thank you. As you know, we have been adding and rather accelerating sales capacity. We are pleased with performance, and we are counting on it to deliver us accelerating growth. Remo, do you want to give a better color to it?

Yes. Majority of our field sales reps are still ramping. So a significant portion of our organization is still in ramp phase. The key thing that we brought up in the past is that we are aggressively hiring. And we had a good quarter of hiring in Q3. We're expecting to have a very good quarter in Q4. So our plans, as Jay talked about in the earnings call, is that the market is really strong. It's moving to us. All indications are that we're in a great position. So we're going to continue to aggressively hire and really go after the growth of the Zscaler going forward.

And if I may add one more statement. One, it's a competitive market for talent. Zscaler has become a top destination for top talent. So we're able to attract good talent and grow our sales team stronger.

Our next question or comment comes from the line of Matt Hedberg from RBC Capital.

Jay, there's obviously a lot of success you're seeing in the enterprise on upsell and large deals. I had a question on the federal or, I guess, public sector market. Obviously, the Colonial Pipeline attack highlighted the risk here that some utilities are at. Just can you talk to us about how you think about Zero Trust architecture could benefit the public sector? And might that be an accelerant as we look forward for the next year or 2?

I think we have been hearing enterprises talk about Zero Trust more and more for the last 12 to 18 months, especially after some of the SolarWinds type of attacks. This is bigger theme. But now, it's good to see that federal government is braking up and saying they need to do something. It's good to see a very clear directive coming from Biden administration, which highlights a need for Zero Trust. And by the way, I must say that many vendors are trying to hijack upon Zero Trust, but Zero Trust as written by the [EU] based on the MIJST research paper, it is not done by firewall. It is connecting entities to entities without a pass-through connection, and we believe we'll have a big advantage of it. We started investing in federal space about 3 years ago, had to go through a lengthy process of certifications of FedRAMP and the like. We are very well certified. We started investing in sales organization about 2 years ago, have a strong team, a strong and growing pipeline. So federal business seems great. And the second part of your question is actually public sector, which is the non-federal part, which is state, local and education stuff. We are doing in that part very well as well. Remo?

No, I think, Jay, you hit it. I mean the key thing is that we've invested significantly in federal. As Jay talked about, the FedRAMP certifications. FedRAMP High for ZPA. And also, we are moving towards FedRAMP High for ZIA, which puts us in a completely different position than other companies. In addition, I think one of the strengths is that we've been able to build the sales organization at the organization very strongly and partners in federal. So I feel we're well positioned in the federal market going forward.

Our next question or comment comes from the line of Greg Moskowitz from Mizuho.

Okay. Congratulations on a phenomenal quarter. Jay, maybe to follow-up a bit on the last question, and you sort of touched on this a little bit, but from what you're able to gather, have the recent high-profile breaches dating back to SolarWinds that inclusive of the Colonial Pipeline attack, have they had any discernible impact on your pipeline. So again, we hear the anecdotes, much like you do. I'm just kind of curious if there's anything that is able to translate to some extent from what you're able to tell?

So first of all, the number of inbound engagement from not just CIO and CISOs, and in many instances, the Board has stepped up. So it's clear that there's a high degree of interest in making sure that companies are secured. That's point number one. Point number two, when those level of C-level get engaged, the budgets open up, they become less of an issue. When you're dealing with the CIO, whose budget is hundreds of millions of dollars, to get a few million dollar deal for us generally becomes a lot easier. So we are seeing tremendous interest. Our customers having discussions that they need to do Zero Trust implementation because of security factors, including Colonials and SolarWinds? Yes. Can I quantify what part of business and pipeline? Probably I'll be guesstimating too much. So I'll leave it open to, say, a positive impact, but hard to quantify.

Our next question comment comes from the line of Gray Powell from BTIG.

So yes, you mentioned that you expanded investment in the mid-market or the mid-enterprise segment -- companies with 2,000 to 6,000 employees contributed a higher mix this quarter. Is there a way to roughly quantify how much of the upside this segment is driving? And then how should we think about the potential contribution from the segment ramping over the next 6 to 12 months?

Yes. I mean, just for clarification, the Enterprise segment is for employees of 2,000 to 6,000 employees per company, and it is the fastest-growing segment that we have. On a quarter-over-quarter basis, the growth for new and upsell business has been a couple of percentage points. What this shows basically is our investments in the Summit Program that we've made so the Summit Program targeted primarily towards bars and bars -- primarily towards the segment, we are seeing very, very good growth, and we're happy with the growth. As I mentioned, it's the fastest-growing segment that we have. The segments we have are majors, large enterprise, enterprise and commercial. So this is the largest one. So this is growing large assets.

Yes. If I may add, it was natural for us to expand into enterprise. We started from the high end, having strong presence in majors and large enterprises. It's a natural part for us, and we are pleased to see the performance. In this area, we have been adding quite a bit of sales force in this area and partner program together is delivering good results.

Got it. And are sales cycles faster there? Or is there anything different in the competitive environment?

Yes, they are faster. As you would expect, typically, the bigger the deal, the longer the sales cycle. The smaller the company, fewer the stakeholders and faster the sales cycle.

[Operator Instructions]. Our next question or comment comes from the line of Mike Walkley from Canaccord.

Just wanted to dig in on the comments on ZPA, about it's going to all users, not this remote. Any way to size the opportunity of further penetration within your customer base? And just thinking about ZPA with it taking off with the pandemic, any thoughts on longer-term modeling, giving potential tougher comps even though the pipeline sounds strong?

So first of all, from day 1, our belief was that ZPA was never designed for remote access VPN only. It was designed as a Zero Trust architecture implementation. No matter where the users are, they go through our switchboard, so they never on the corporate network. And when pandemic happened, since everyone was remote, so ZPA actually got bought from almost every employee most of the companies, that was a big shift we saw. Whereby previously, companies would buy ZPA for 20%, 30%, 40%, 50%, 60% of the employees. But we knew the number will get to 100%. And as employees are coming back to the office, in fact, customers are worried about these people bringing their infected machines back to the office, so they want to do Zero Trust even when they're in the office. So for that, they want to go through our Zero Trust Exchange. In fact, for that, we built another service, we call it Private Service Edge. Imagine a private switchboard running in your data center to implement Zero Trust for on-prem users, which is actually a great opportunity further giving customer segmentations for the applications, which is what customers are looking for. So I think it's a matter of time. And every employee of our customers will have ZIA, ZPA and actual ZDX as well. Because while ZIA and ZPA allows you to work anywhere and access any applications, ZDX makes sure users have a great experience and the issues, they can be easily solved.

Yes. And from a penetration perspective for our ZT customers, a little over 40% have ZPA. So significant opportunity for us to upsell into our existing customers -- sorry a little over 40% of ZIA customers, to clarify.

That is correct.

Our next question or comment comes from the line of Andrew Nowinski from D.A. Davidson.

So had a question on the CrowdStrike win. You hear a lot about how endpoint security and specifically EDR technology is necessary to stop breaches like the Colonial Pipeline attack. And given that CrowdStrike prides themselves on stopping those breaches, I'm wondering why they would need Zscaler? So if you could provide any more color on -- maybe on what they're deploying and how they're using Zscaler and whether you think any other enterprises may follow their lead and deploy both CrowdStrike and Zscaler together?

We are yet to come across a serious large enterprise who doesn't believe in clear security approach, but endpoint serves as an important layer and cloud serves as a second layer. That's the most common thing I do. So it's -- when you bind to that notion, which is what we do and most customers do, it's natural for customers say, endpoint from CrowdStrike and cloud security from Zscaler. And what's exciting for customers is for the 2 to be able to work together with proper API-based integration, CrowdStrike and Zscaler had done this product integration over the past 12 to 18 months and that integration keeps on going to the next level, where we can help each other and customers get the benefit of it. So driven by product integration that customers wanted and then our joint sales engagements on field, where our teams are working together because we complement each other, it's a great win-win partnership for both of our -- both of us, CrowdStrike and us. Did I answer your question?

Yes, it did. Thanks, Jay.

Our next question come comes from the line of Keith Bachman from Bank of Montreal.

Jay, I wanted to see if you could give some more color around both ZCP and ZDX. And the question really is, any comments or color on attach rates? How much are contributing? Where the wins are? Any more color, so we could get a sense about how much those assets, new solutions rather contribute today? And how you see that unfolding over the next 12 months?

Yes. Thank you. I'll start with the strategic positioning, and Remo can add on the point at side of it. As you know, ZCP, is cloud protection is a massive opportunity for protecting workloads. There are a couple of areas there. One big one is communication among workloads, which has traditionally done the whole school way by connecting various workloads and availability zones with a wide area network, site-to-site VPN and the like, which creates big risks because of lateral moment. So with workload segmentation, we have implemented a zero trust architecture which will disrupt legacy network-based security for workload just like with direct users with ZIA and ZPA. That's one part of it. And obviously, it's easy for us to start with our own customers, and that's a large customer base, and that's where early traction is. And then on second side is the security posture type of stuff. This is where some of offering is cloud security, posture management, CSPM and Trustdome acquisition combined give us a strong offering. We are bullish about the ZCP market, which is nascent, but it's growing rapidly. The ZDX part is very interesting. This is complementing ZIA and ZPA to identify and resolve any user performance issues. So this is a natural add on to any ZIA and ZPA sales. Normally we used to sell ZIA only. Then we started selling ZIA and ZPA together. More and more deals are with ZIA and ZPA together at the start. And now we are seeing more and more deals with ZIA, ZPA and ZDX together, which makes a natural bundle for our customers to enable their employees to work here and have great experience. Remo color on...

Yes. I mean, just from a numbers perspective, we still expect the contribution for new and upsell for ZCP and ZDX to be mid-single-digits this year. As Jay mentioned, the reception of both products has been high, and we feel good about those products going forward. But think about the contribution this year for new and upsell in that mid-single-digit range.

Our next question or comment comes from the line of Patrick Colville from Deutsche Bank.

So just on the math, CRPO billings, if I'm not mistaken, rose 85% this quarter, which looking at the disclosure since you guys have been kind of giving RPO and CRPO seems to be the kind of highest growth rate ever. So hugely impressive. What are you guys seeing to kind of have this real acceleration this quarter, what are the kind of confidence and factors? And I guess kind of importantly, how sustainable are they as we look forward into the rest of calendar '21 and '22?

Yes. I'll take the first part and have, Jay, give some color. You're right, Patrick, outstanding results. I mean the CRPO growth is 68% and the RPO growth is 85%, which is absolutely outstanding. When you couple that with our billings growth of 71%, it just shows that, basically, things are going very well for us. What's changing is basically what we've seen. We've been talking about with the accelerant last year related to with COVID hit, and companies recognized that they had to get their employees connected to their networks in order to -- or applications in order to do business. And we saw that. That was the big increase for last year with ZPA, which is 43% of our new and upsell business. Since then, basically, that brought to light, it's basically that yesterday's networks aren't going to work. Infrastructure is not going to work. Those are the discussions that we've been having with customers. That is basically a change, which is occurring, is recognizing the current infrastructure in place is really not the optimal infrastructure that companies need going forward. With that, what we've done as a company, we broadened our platform. We broadened our platform. We just talked about ZDX workload protection and additional basically features onto our product. So the broadening of the platform related to the movement to really transforming your networks has led to basically deal sizes becoming larger, more strategic partnership. And also, just the credibility of the Zscaler, now that they've on a public company for 3-plus years and we've got a strong balance sheet, and we've got a strong team. And again, the key thing is Zscaler was built for this world. The platform was built for this world over 10 years ago. And it was -- if you take a look at the expansion basically of the amount of traffic that we put through to have the type of gross margins with the type of traffic across over 150 data centers, with SLAs being almost zero, quite frankly, on a quarterly basis, is a testament to the strength of Zscaler. And I think that's what's playing through with our communications with our customers. Jay?

I think you said it all, but accelerating digital transformation being one; expanded portfolio and platform being 2; large, great sales force being three; and our brand and customer [acquisitions], all four are accelerating our sales.

Next question comes from the line of Catherine Trebnick from Colliers.

Can you unpack a little bit the Summit Program and how well you're doing there versus your sales through the service provider channel to give us a better idea where you're really seeing explosion in your opportunities?

Yes. Our service provider channel evolved fairly early on. As our customers want transformation and CIOs told SPs to work with us to make that happen. It's a strong channel. It's a growing channel. For us took time in the past couple of years, more and more of the VARs, they realized that. The box sales are not going to last forever, so they are pivoting more. The one who are pivoting to embrace cloud transformation services, they are our favors. They're actually becoming part of our Summit Program. That's what the part -- program was built, and we have good participation for programs. And as a result of that, we're seeing the growth of VAR contribution to business growing at a faster rate.

From a numbers perspective, also, VARs as a percentage of our revenue is in the low 50% range. SPs and SIs combined in the low 40%. And direct is mid-single-digits. The growth rate in SPs and SIs has been significant year-over-year also. So we've had significant growth in SPs, SIs on a year-over-year basis.

Our next question comes from the line of Saket Kalia from Barclays.

Actually, maybe just to piggyback off that last question on channel. Maybe a little bit more of a strategic one for you, Jay. The service provider channel has been an area that these dealers worked with for years, as you noted, and it felt like this quarter, you're starting to see some other security vendors maybe start to work with them a little bit as well. I guess the question is, how are your conversations with those service providers? And how do you think that sort of plays out in the future as other security vendors maybe start to work with that channel as well on SASE specifically?

Yes. So first of all, as Remo said, our business, the SP, SIs year-over-year is growing quite well. Think in terms of other firewall type of vendors, that's not new news. Service providers have been selling firewalls, have this stuff, especially for MSSP servers for years and years. So not a new area. Yes, adding the SD-WAN to those firewalls is probably a new area of we hear about. But most of that stuff has happened on the lower end. When you talk to larger enterprises, they actually engage with us and then partner together and drive the transformation. None of that has changed. On the lower end, probably this combination of some SD-WAN combined with firewalls, but we are bullish about the SP channel, SI channel as well as the VAR channel. In fact, our investments in channel are growing significantly because that's giving us more and more leverage, and we will continue to do so.

Our next question comes from the line of Tal Liani from Bank of America.

When I ask you, why are you successful? The answer is always the same. So I'm not going to ask you again. But I want to ask you about condition. And the fact that you're so successful for such a long period of time, and we do see new players in the space. I'm wondering how the competitive landscape changed? What's the -- what do you see today in competitive bids versus what you've seen before? And how is the gap between you and the competitors? So anything you can share with us on the competitive landscape?

We ask this question to ourselves many, many times. We analyze it every quarter. Frankly, the truth is not a whole lot has changed on the competitive landscape. We’re hearing so much noise from firewall vendors and the like. Have we seen any change? On the larger segment, larger customers that we always talked about haven't seen change much at all. We have seen a few cases. And I mentioned a couple of them during our prepared remarks. We have firewall vendors trying to go in and compete but got disqualified because they don't have the architecture. Well, you could say that now, some of them are saying, yes, we have a proxy architecture. But announcing is one thing, building a scalable, reliable proxy that a larger enterprise would depend upon is a very different thing altogether. Having said that, when we come down to the lower end of the spectrum, say, under 5,000 users, so we do see some of them. Vendors where it's kind of less security savvy customers. But as we are engaging more and more in this space with our Enterprise segment, we do some of them. But once we engage, we are winning pretty handsomely. So very comfortable on the competitive front because customers are more and more actually on every segment looking for consolidation and simplification. So low end players that are coming from point product and trying to expand, so to speak, don't really make it well. Some of the bigger ones, our legacy vendors, the old story, our Zero Trust Exchange platform does much better because we are truly a zero trust architecture. And as I said, you can convert a firewall into a zero trust architecture. That's kind of oxymoron.

Got it. And do you feel that you need to make acquisitions in order to grow the TAM? Or is it more time to focus on execution and sales and marketing and just try to -- within your current TAM, try to get more market share? Where is your focus between the two?

It's a good question. Both. Why not? Having said that, I would say we won't be looking for acquisitions to grow TAM. We're looking for acquisition to fill in any potential areas that need to kind of strengthen or expand into adjacent markets. It's pretty open to. We've done a few small acquisitions at the right opportunity with the right technology. We'll look for everything that makes business sense. We see that as a market opportunity for us, our momentum is so good, so why not keep on moving at a faster pace. And on sales and marketing, we are investing. We're investing heavily. In fact, Remo and I have lots of internal debates, our top-line growth versus bottom-line. We kind of say, hey, top-line is a priority, so both of us happen to be such that we can't be spending like drunken sailors. You'll also see our bottom-line being pretty good.

Our next question or comment comes from the line of Erik Suppiger from JMP.

Just in the SD-WAN space, who are your best partners at this point? Are there different architectures for SD-WAN that fit well with you? Or how do you look at that space?

SD-WAN. So the answer is pretty simple. Starting with vendors who compete on the higher end who have enterprise-class architecture, they are natural to work with us because our large customers want them. As I said kind of before there, 3 vendors we see frequently for SD-WAN deployments of large enterprises. It's VMware, it's HP Aruba, and it is Cisco. Most of our customers have one of the three deployed on the high end. Then the low end customers coming from the firewall side of it, do they have some large enterprise customers? Yes, but a lot of their business ends up being on the lower end, and we see them less often. But we do have customers who may have and other SD-WAN vendors, but they decided that we were the security cloud of choice. And we're open. We integrate with everyone. I can take traffic from almost any SD-WAN vendor but with some of them we have stronger working relationships. VMware is our best partner when it comes to go to market.

Our next question or comment comes from the line of Hamza Fodderwala from Morgan Stanley.

Jay, just maybe a high level market question for you. I think some of this you touched on earlier, but we're clearly seeing a critical math in terms of adoption of trends such as SASE and Zero Trust network access, a lot of the stuff that, obviously, you've been aligned towards in day 1, and you're clearly a big beneficiary of that and have been. But at the same time, I think at least in the short-term, it seems to be kind of a rising tide lifts all boats, right? And many of the firewall competitors that you mentioned earlier are talking about similar approaches. Not to necessarily go you to talk about any one particular vendor. But at what point do you think that some of the FUD, right, from your perspective, kind of winnows down and people are -- look for a solution that's truly architected for this trend like you've talked about?

Yes. We've seen this movie before. If you recall, there's some proxy vendors whose sales were rising and [indiscernible] Jay, you guys are winning, why aren't they losing? I mean we are still young. We still have a small for the market, with 25%, 30% of the customers deployed us. What are other guys doing to keep on dealing with the data-centric architecture, network-centric architecture? They're buying more and more firewalls, right? It will be -- it will take some time and that is powerful thing. But I think when it comes to doing truly the new architecture with Zero Trust, where you don't put people on the network, you don't have a pass-through architecture, that's the only way to stop Colonial type kind of threats and SolarWinds type of threats. I think you'll see things changing. And that's what I think. Overall, the market is pretty big right now. We aren't really inhibited or impacted by any of those competitors who are doing well. I think -- and our share will keep them going for some time until the architecture really changes. Take, for example, spinning a VPN in the cloud doesn't make anyone Zero Trust. It's still VPN. Our customers are buying and deploying it? Of course, they are, alright? Will that change over time? Of course, it will. Can you make VPN into Zero Trust? You can't.

Our next question or comment comes from the line of Rob Owens from Piper Sandler.

Great. Jay, relative to return to work and we think about reopening, how would you expect the pace of digital transformation and therefore, network transformation potentially change? And where are customer conversations right now around the sense of urgency?

So customers are beginning to make plans to come and work from the office. Many of them have partially opened up. What they learned during the COVID crisis was that the corporate network doesn't play a very important role. They could work from anywhere. But having said that, when employees are in the branch office, they need to make sure the traffic and go directly from the branch office to the cloud, just like it went from employee’s home directly without going back to the data centers. So that is actually restarting some of the SD-WAN projects so they can do local breakout. But the bigger issue that's helping us, or the bigger opportunity that's helping us is, they want to make sure employees in the office still do Zero Trust architecture with a product like ZPA. So we are seeing good interest in fully Zero Trust, so they don't have an issue where the lateral movement of threats like SolarWinds can get them in trouble. Or the infected machines coming back to the office and get them trouble. And we are helping companies implement better security, full security asset return to the office as well. Overall, a good positive opportunity for us.

We have time for one final question. Our last question comes from the line of Brian Essex from Goldman Sachs.

All right. Back on the bus. I really appreciate it and congrats on the results. I was wondering, maybe, Jay, if you could expand a little bit on some of the drivers here in terms of -- you've got macro headwinds. You've got sales productivity. You've got transformational shift to the cloud. Expansion of your platform. How does that relate to customer growth? Is there any way to kind of quantify customer growth and then grade those tailwinds in terms of which are the most meaningful with regard to the growth trajectory that you're experiencing now?

When you said customer growth, are you telling a number of customers or revenue growth?

Yes. I guess I'm looking for logo growth relative to some of the kind of platform expansion and sales productivity initiatives that you have currently in play?

Right. We are doing well in both areas, new logo growth and upsell. It's an interesting bearing in the company should be -- pay more for new logo or not, okay? And we decided not to do because there's so much an opportunity to sell the platform, which falls under upsell. The new logo, we have a good mix of business coming from new logo as well as upsell. So the opportunities, as you said, the macro environment is helping, more focus on security is helping us. Sales force, they have done a phenomenal job in the sales organization. Now we are seeing very good results from our early focus on channel, Summit partners. Marketing, we've got a new CMO. We expanded and strengthened the marketing team, a lot more investments in the marketing area. And platform and product machine is really coming at a very good speed. Very bullish on our opportunity going forward.

Yes. From a total customer perspective, we grew our customer base by about 20% year-over-year.
