Thank you, Marc, and thanks to everyone for joining us on the call today. Our 2018 is off to a great start, with an outstanding first quarter performance. Our success continues to be derived from our deep roots, serving our customers. Bandwidth has a tremendous opportunity ahead, and we are well positioned to fulfill our mission to develop and deliver the power to communicate. Communication between customer and company is at the very heart of how healthy enterprises operate, innovate, and drive growth. Today, organizations increasingly embed mission critical communication functions in their products and services, to deliver real-time, connected experiences. Our market is growing, because of enterprise demand for cloud applications and integrated communications experiences within workflows, customer facing applications, and business processes. The rapid progress of consumer and business, voice driven communication experiences is also increasing demand for our software powered communications platform. We are honored to serve many of the leading companies, who are ushering in this new era. Our customers choose Bandwidth, because we empower them to embed seamless communications within their products and services, in a reliable, flexible, scalable and cost efficient manner. Enterprises require the versatility of a cloud-based software platform, coupled with the reliability of a network provider, to address their end-to-end communication requirements. We are the only software platform, that provides complete communication solutions, with integrated 911 services, which connect end users to emergency services, with reliable and accurate emergency routing. To summarize the first quarter results, total revenue came in at $53 million, and was highlighted by a 23% year-over-year increase in CPaaS. This was above our expectations, driven by robust demand and a focused execution of our team. Our accelerated CPaaS revenue growth during the first quarter came primarily from the expansion of our relationships with existing customers, evidenced by…

Thanks David and good afternoon everyone. On the call today, I will provide a more detailed overview of our first quarter financial performance, and then provide our outlook for the second quarter and full year 2018. Following my remarks, we will open up the call to your questions. First quarter was an exceptional performance for Bandwidth, highlighted by accelerated revenue growth and better than expected results across all guided metrics. This was primarily driven by existing customers, but also from new customers, which combined, drove higher usage levels across many of the offerings on our platform. We enjoy strong ongoing demand, as enterprises continue to embed voice, messaging and 911 into their products and services. During the first quarter, our total revenue was $53 million, up 34% year-over-year and $5.5 million above the high end of our guidance range. Within total revenue, CPaaS revenue was $38.9 million, up 23% year-over-year, and $2.4 million above the high end of our guidance range. The remainder of the revenue upside came from other revenue, which contributed the remaining $14.1 million of total revenue, up from $8 million in the first quarter 2017. Other revenue included a onetime benefit of $6.3 million related to the Verizon legal settlement in the first quarter, which was greater than the $4.4 million we had assumed in the guidance on our last call. This was due to the fact, that we were able to reconcile and provide bill credits from amounts previously billed, faster than anticipated, and therefore, recognized the full settlement in the first quarter. Excluding this settlement, our year-over-year total revenue growth would have been 18% in the first quarter of 2018. We ended the first quarter with 1,028 active CPaaS customer accounts, up 26% year-over-year. In addition, our dollar-based net retention rate was 115% compared…

[Operator Instructions]. Our first question is Meta Marshall with Morgan Stanley. Please proceed with your question.

Hi. Great. Thanks and congratulations on the quarter. First question, just kind of digging into gross margin, and your guidance that it would be kind of similar to full year 2017 and just given the upside in Q1, just wanted to kind of dive into that. Is it due to investments internationally, is it due to kind of the customer you mentioned moving into the next year, and that's the first question. And then the second question was just, if you could give kind of a source of upside that you mentioned usage being the source of upside, the CPaaS in Q1; is that more concentrated with a couple of customers, is that concentrated with your larger customers, or just give a sense of, is that kind of evenly distributed throughout customers? Thanks.

Thanks Meta. This is Jeff, I will take the first crack at this one. So regarding your gross margin question, there are a few moving parts in here. As you know historically, we have grown our overall gross margins, about 80 or 90 basis points each year throughout our history. This year, we will be flattening a little bit, and we certainly, have in the other revenue segment, Verizon, with a positive there. But what's offsetting that to flatten the margins in 2018 is further investment, and that is us putting the IPO proceeds to work, to invest in the business for long term growth, and we are doing that on the voice side, the 911 side, as well as messaging. As to your second question, as far as the Q1 growth, it was really strong demand across the board, and as David had said in his prepared remarks, the vast majority of our growth continues to come from our existing customers, and that was reflected in our dollar based net retention rate of 115%. I will note that we did see a uptick in the quarter as well in new customer demand and we saw that in both new customer revenue growth, as well as the number of -- the growth in the active CPaaS accounts as well.

Got it. I will pass it on. Thanks.

Our next question is with Richard Davis with Canaccord. Please proceed with your question.

Hey, thanks. Two quick questions; one is more just a background. So I am over in London right now. So GDPR is a pretty big issue. One of the things that we have heard from software companies over here, is that, they think GDPR is going to be a bigger deal for B2B contacts rather than B2C, because the buying behavior, the acquisition of lists and stuff like that, etcetera, was I guess more -- just coordinated GDPR for B2B than B2C. So the question is, does that make -- I think the answer is no, but does that make any difference at all to you, in terms of mix, B2C or B2B? And then the second question is, I saw that you guys introduced -- I think it's enterprise A2P messaging system. Could you just kind of talk how that kind of matriculated down the pipeline and what you'd see for that? Thanks.

Certainly Richard, thank you. This is David. So regarding GDPR, in your question relative to the degree of difficulty for a B2B company like ourselves versus a B2C, what I can certainly share is, we have a sales team that operates off of a curated database of medium sized customers that we have built over the last decade, and a very strategic sales team that is outbounding on the Fortune 1000. So our prospect, targets and lists are something we have worked with for some time. So I don't foresee any particular or novel GDPR challenges for us as a B2B. I am not able to speak to the degree of difficulty, difference between us and a B2C company. If that answers that question?

Yeah. No that's helpful.

Great. And then, in regarding SMS A2Ps; as you know, when you are doing messaging outbound to people, there are rules and there are very important protocols to follow, to allow you to go-to-market effectively, and respect the entire ecosystem that supports messaging. We have implemented the appropriate technology for us to be able to make that offer and feel good about the product market fit. So that's how it has come about. It's through a rigorous understanding of what the messaging ecosystem demands, as we all endeavor to make sure messaging remains a very rich, signal carrying media that it is today.

Super. That's super helpful. Thanks so much.

Our next question is with Brent Bracelin with KeyBanc Capital Markets. Please proceed with your question.

Hi, this is Alyssa on for Brent today. I have kind of a follow-up on the CPaaS revenue upside, kind of within your existing customer base, is there anything to think about regarding upside and top 10 customers versus broad-based and anything to think about versus seasonality versus sustainability of kind of that growth that you are seeing there?

Thank you. And I will go first. This is David, and then Jeff, can respond as well. Our growth, as Jeff indicated earlier, has come from a broad and diverse set of customers. There is no concentration in a way that we find particularly notable for upside among a singular customer or a segment. So we have been watching usage and enjoying the tide rising across the board. But I will ask Jeff if he has additional color?

Yeah. The only thing that I would add on seasonality, is we really don't have any. If there is any factor that I would look at or a number of effective business days in a quarter. And when I say that, sometimes in fourth quarter, around the holidays, whether it's an official national holiday or it's just one next to one, we will see some usage impact there. But overall, not much seasonality quarter-to-quarter.

Great. Thanks. And then, on kind of your new CPaaS customer adds, is there anything to think about kind of standouts, as it relates to either verticals or big new customers, or any other color around that new customer adds?

Yeah. I think what we have said, it was really a strong performance across the board. Verticals that we had mentioned in the past, that we continued to do well in conferencing, is a great space for us. Mobile has been very good for us, and we have a number of internet giant customers that have performed very well for us. So it remains very diverse and the growth is coming from all areas, product wise, as well as size of customer.

Great. Thank you.

Our next question is with Will Power with Robert W. Baird. Please proceed with your question.

Yeah great. Yeah, congratulations on the Q1 results. A couple of questions; I guess, first, looking at the profitability guidance for Q2, it implies an uptick in investments. I wondered if you could just give us any more color, how much of that is related to sales versus products, some of the work you are doing, 911 messaging and enhancing that, and then I guess the second question is, maybe just an update of where you are in the sales hiring process? Is that on track? Any numbers, parameters you can provide around that? Thanks.

Thanks Will. This is David. During the quarter, we did invest our proceeds in areas of the company that we are excited about, and much of that investment takes the form of hiring, and as I mentioned in my comments, extremely proud of the team's ability to harmonize so many people in so short period of time across the company. And those folks are in sales, as the second part of your question indicates, and we feel as if we are executing or hiring on plan, and are proud of our team and excited about that. Yes, we are developing messaging as a product, as we have talked about, and that progress and that investment is ongoing, also according to plan. And on international, as we mentioned, we have onboarded our leader in that space, and this is a learning year. But we are investing broadly in terms of hiring across the company, and doing so in a way that we think is on plan.

Okay. Thank you.

Our next question is with Catharine Trebnick with Dougherty. Please proceed with your question.

Oh, thanks for taking my question. Congratulations on the strong print. Well I have a housekeeping question quickly; do you break out your stock based compensation against the line items on the income statement?

We will. That will be in our 10-Q which we expect to file in the very near future. So we will have that for you shortly.

Okay, great. Then just more with the IPO money, you are investing more, and I have been jumping between three phone calls. I appreciate if -- I hope I am not asking the question again, but one of them was, where are you in hiring for sales and marketing, and is there also more emphasis on an indirect channel than in a direct channel in your go forward marketing strategy?

So thanks Catharine. No worries. We are on plan and are hiring both in sales and across the company, and our strategy is all direct. So we have an inside sales team and strategic sales representatives that approach enterprises direct, and we really value the customer relationship directly and have, over years. So we won't be pivoting or adding an indirect sales team that's not part of our plan.

And then the other question, is there more clarity or color around the large customer base. Has there been -- four very big products obviously, and is there more -- how can we analyze or quantify, if there are new used cases within each of these larger players, internet giant players that you have?

Our large enterprise customers, as you can imagine, are very proprietary about how they work with us and in what products. And many of them compete with each other, and so we need to be respectful about how we work with our enterprise customers. So it's hard for me to give you a clean guide on how you can understand when we are even more deeply embedded within these large enterprise customer accounts. But it is consistent, that over time, we have continued to add products that we support within each of our largest enterprise customers, certainly within the top 10 and beyond, and we don't see that trend either going flat or reversing any time soon.

All right. Thanks. I had to ask. So appreciate you take the question.

Our next question is with Pat Walravens with JMP Securities. Please proceed with your question.

Oh great, thank you and congratulations you guys. Very impressive. So Dave, maybe to start, how do you think about the international opportunity, like what regions are most attractive and what makes the region attractive?

Thanks Pat. Here is how I think about international; it is attractive based upon -- if you are our current customer and I was talking to you as our primary relationship, Pat, at the company, I would understand what your spend is in a particular jurisdiction, and that's what would make it most interesting, relative to others, who are spending less or on a service that is more difficult to provide in that jurisdiction. So I would describe that approach as opportunistic, or if you will, not build it and they will come, but instead, follow demand. And while that may not appear to be overly ambitious, we have historically taken a very responsible and prudent approach to how we grow and invest. And so we are being, we are focusing on 2018 as a learning year, where we prioritize jurisdictions for entrants based upon our current customer base and what they are serving in that place today. Does that answer your question?

Yes. But I got more. Where do the net dollar expansion rate -- yeah, I know. I think I am probably the last one, so I am going to put in a couple here, if it's all right? The net dollar expansion here, that's great, right, what a great move. How should investors think about where that goes from here?

Hey Pat, this is Jeff. How I would think about it is, we are now in a range, where I think investors could -- will be in there. It could move a little bit, depending any given quarter that would be in there. One of the things that we had, was talked about, was we did have one large customer, that had reached a higher volume pricing tier within there. So there might be a little bit of pressure in the next quarter or two. But I think the 115% is about right.

Okay. And then, similarly, how should we think about the CPaaS growth longer term? Like, not sure how you want to answer that, but is it something that should keep accelerating, is this about the right point, how do you guys think about it?

I do think that that is a -- that's a billion dollar question. It really is exciting to see across the board, how voice is growing and how messaging remains a creative canvas on which lots of things are painting and we are supporting those. And we think the market is dynamic and is fluid, and it won't coalesce to a fixed rate of growth or to winners and losers for quite some time. So it is a wonderful opportunity to have resource and to be investing and to be building. But we really don't know what the terminal growth percentage, 18, 24, 36, 48 months out really is.

Okay. All right. That's super helpful. Congratulations again.

Thank you, Pat.

[Operator Instructions]. Our next question is with Josh Goldberg with G2. Please proceed with your question.

Hey guys. Just a question about the reinvestment of the IPO proceeds. Based on your guidance of the second quarter, just so I get it right; if you are assuming gross margins similar to last year second quarter on 44%, you'd have to spend an additional $5 million on operating expenses. Is that the right way to look at that? And I have a follow-up?

Hey Josh, this is Jeff. Yeah I think that is the right way to look at it. I think how you can think about that expense, is additional hiring in sales and marketing, as well as R&D, and to the extent that we need to support our growth within G&A. There is some timing of projects, that are more one-time in nature, that I would describe as IT and finance related, that could fill that up in second quarter.

So is that second quarter number kind of the high watermark for the year, or you expect it to trend up from there on expenses?

I would say that's in the range of the high watermark. But third and fourth quarter would be in a similar range, plus or minus.

And your level of conservatism based on the spending that you are doing? Regarding the CPaaS revenue, obviously 23% on the net retention rate, really strong. Maybe talk a little bit about, what you are seeing that's getting you to this much faster growth rate, and how obviously, the confidence in the back half of the year is based on the large customer increasing. But it would seem like, you are just adding a lot of customers having a higher amount per customer and getting more retention. It just seems like a lot's going your way right now in the first three months of the year?

This is David. I think that's a fair overview. Our customers on average are spending $150,000 with us and that's consistent with our past, so there is no significant change in that, and we are adding more customers, as we noted. So I think you are generally, directionally correct.

Was there something related to usage [indiscernible] the quarter, or you felt, this is more like a recurring revenue stream that you feel comfortable with?

Well we are just a usage based business. So that's the primary driver for an increase.

Ladies and gentlemen, we have reached the end of our question-and-answer session. And I would now like to close the conference. Thank you for your participation today. You may now disconnect your lines.
