Great. So, challenges in the past have been – there's a lot of them. So, one is just the inefficiency that exists in the system. And, as well as, kind of the hesitancy in the past for private companies to offer liquidity options. I think that's been frankly, the biggest impediment in the past. You know, private companies, obviously, when they bring in early stage investors, they want them to be in there for a long time. When they issue equity to their employees, they want their employees to be locked up for a long time. However, today, it's a very, very vibrant environment, and private companies are staying private longer. And over time, they realized that unlocking liquidity is actually can be very creative, because number one, their employees over time, they want to buy houses and send their kids to school and be able to use their equity in ways that help manage their lives. And so, offering a fair way and in a high integrity way to offer that liquidity is really important. The second – and to attract talent to these days to have some sort of liquidity program as part of talent acquisition for private companies becoming more interesting and something that we're seeing. The second is that obviously getting early stage investors, some returns, and then bringing in later stage investors who can carry the firm's over time into the public markets is highly interesting. And so, there's just been this really steady increase in corporate interest in liquidity. And we've seen an acceleration of that in the last couple of years. Private companies are really balancing, do we go public, do we stay private? If we stay private, how do we make sure that we have a nice liquidity capability within the company? And then of course, with direct listings, there's what we call continuous trading programs that are being developed in advance of those companies, tapping the public markets. So, I think all of those things have accelerated the interest. And now it's a matter of us really bringing together the institutional community, the venture community, and the private company community to – and our, obviously our technology capabilities, and our market knowhow to say, okay, how do we catalyze this into a really robust and efficient liquidity marketplace? So, we see this as being, you know, just a huge opportunity. In terms of the total market opportunity, it's hard to measure something that doesn't exist, but when we look at it and say, what do we think the liquidity could be and what kind of, you know, revenue opportunity could there be? We actually size it anywhere between, kind of 500 million to 1.5 billion. So, it's a big opportunity that we're going after, over the next 5 years to 10 years.
