“As a Y-Combinator, 500 Startups, Forbes 30 Under 30 alum I have interacted with thousands of investors, and David easily falls into top .1% of them. He’s fully committed to helping entrepreneurs bring their vision to life. He works tirelessly and selflessly with his portfolio companies, and has been an amazing sounding board for me at Go X. He will pick up the phone at 3 am and work through the weekends. Just like me, he’s crazy enough to believe that we can change the world and is working hard to actually do it. Success of his portfolio reflects the hard work he puts in. David is everything an entrepreneur would dream of having in an investor: mind, network and heart”

Alex DebelovFounder and CEO, Go-X

“David is a very diligent, well-connected and effective person to work with on a strategic approach to fundraising and corporate growth. I have recommended him to [founder] friends before and am happy now to recommend him.”

Greg SchmergelCo-founder, Chairman, and CEO, Nantero, Inc.

“I had the opportunity to see David build the first stones for one of his businesses while we pursued our MBA. David showed true passion and drive to see his business through. His tenacity keeps him motivated, as was the case when one potential investor dismissed his idea altogether, and David not only persevered with his business but ultimately convinced this angel to put faith and money in that same endeavor.”

Andres BilbaoCo-Founder @ Rappi

“David is a true founder-investor - he's been there. Beyond just providing capital, he knows what founders need in terms of support, responsiveness, and creativity. He's opened up his network to us to help access new pools of capital. Many people show up with capital and that's great. David goes above and beyond that and in addition to his checkbook, he opens up his network, his reputation, and his genuine total commitment to founders he backs. I plan to actively seek him out for every company I launch or back.”

Ray SturmCo-Founder & CEO at AlphaFlow

“David is a rockstar connector and executor. Within an incredibly short period he introduced us to a dozen venture capitalists and angel investors (including from the very top firms). Outside of this David was able to connect us with executives at the very top level in very hard to reach companies with significant revenue potential. Everyone has a core competency, and David’s is getting to hard to reach people and creating enormous value for all parties involved.”

Yuri KhidekelFounder & CEO at Artsai

“David's commitment [...] is tireless, and his ability to define and attack problems is incredible, and almost tiring just to watch. He's persistent, smart, and self effacing enough to know when he's reached the bounds of his ever-growing knowledge base, and never hesitates to ask for help. I'm excited to see what the future holds.”

Tim DybvigCo-founder & CEO at Calibrater Health

“David is a stellar partner. He is one of the most supportive, accessible, and communicative VC's I've worked with. More important than being uber connected -- which he is -- he's willing to connect the dots on your behalf. He is a fully engaged team player who thinks strategically about the growth and development of the companies he invests in. I feel fortunate to have him as a partner and investor.”

Eric SatzFounder and CEO, AltoIRA

“David has been instrumental in JetBridge's success-to-date in building a disruptive software outsourcing company across Eastern Europe. In the dark early days of the company when we were not profitable and searching for PMF, David stuck by us and rolled up his sleeves to build traction with us. As I'm on my 3rd startup venture I've had a lot of time to reflect on the founder journey, and I'm now convinced that every startup needs someone like David on their team to 10x their chances of success (pun intended :).”

John Sung KimFounder and CEO, JetBridge

“David is a fantastic investor and has been a true partner to our company since we became a portfolio company. He has provided strategic guidance, advice, and support through both challenging times and good, directly contributing to our continued success. He has also opened up his incredible network on a number of occasions to bring us invaluable opportunities that further support our growth. His expertise at navigating startup waters at every stage continues to be a major asset to the company as we enter each new stage, and I feel lucky to have him on our side through each phase of our journey.”
