David is one of the most brilliant people I have ever worked with. We knew each other all through undergrad and through graduate school. The only thing more extraordinary than David’s genius is his work ethic. If I ever start a company, I’m calling him to beg him to be the CTO. He has a very rare blend of technical excellence, business acumen and social smarts. I would highly recommend him for any job where he has a high degree of autonomy and extremely difficult problems to solve.
