Big news today: @Envestnet_ entered a definitive agreement to acquire @Vestmark! I’ve been involved in dozens of exits, but this one is very close to my heart. I started Vestmark with my fraternity brothers (and my actual brother), writing the first few lines of code myself by hand, all the way through today where the company supports 2T+ in assets, 5+ million accounts, and is leading the way with cutting edge AI solutions in a heavily regulated space. I’m so proud of the 100s of incredible individuals who made it their life mission to build Vestmark, working alongside me, and then carrying the torch beyond my time as a 9-9-6 founder. We only got here because of you! I’m also grateful for all of those who worked so diligently to unite these two great companies: the employees, the leadership teams, the respective boards, and an extra shoutout to Karl Roessner and Colin Motley. Looking ahead, I’m comforted knowing Vestmark will be in the extremely capable hands of Chris Todd, a trusted, seasoned operator in the space. This is just the team to maintain Vestmark’s trajectory! As this chapter comes to a close, I’ve got a lot to look forward to. I’m back to working deep in the code, building something new and close to my MIT roots. Stay tuned for the launch! -Dave Blundin The deal is expected to close in the fourth quarter, subject to customary closing conditions. Press Release here:
