Matthew Tillman is a Co-Founder OpenEnvoy (Riot, RRE) | Gartner Cool Vendor, AI for Finance. Investor in 100+ startups. at OpenEnvoy. Colleagues describe him as "I have had the pleasure of working with Matt and being an investor of his for a number of years. Matt's has an ability to not only think technically about solving a problem but he brings a macro view from finance that is hard to top. It is hard to find founders like Matt that have the ability to see a big picture vision and drive a team and organization to execute on that vision. I look forward to doing more with Matt at Haven and as a friend.", "I've known Matt for over 5 years both professionally and personally and over that time I've developed a great respect for him both as a person and as a colleague. The best thing about Matt is he gets the job done. That may sound cliched, but it's fitting. In his time at Adchemy Matt wore at least four different hats. In each case, Matt was able to size up what needed to be done and move the team and company in that direction. If you sit down and talk with Matt for a few minutes, you'll realize that he's been working since the day he was born... and loves it. Matt brings with him years of experience in many different roles. He's leveraged this experience along with his hard-working attitude to really qualitatively and quantitatively improve the companies that he's worked at. Overall, Matt's just a great guy and I'd recommend whole-heartedly to anyone!", and "As our resident Agile expert, he was personally accountable for successfully keeping the delivery and release process running smoothly at Adchemy. Matthew could write his own book on Agile development - and he has the judgment and confidence to know when to invent something new. He's a great asset for any results-oriented product team. I'd recommend working with him at any company stage. As an added bonus, he's just a lot of fun to work with and team morale seems to magically improve around him."
