About Me

holder-picI’m a serial entrepreneur with 2 exits, angel investor in 50+ companies and host of Venture Studio.

I’m also the Director of Entrepreneurship at Columbia University, Adjunct Professor of Entrepreneurship at Columbia Business School and was the Director of Columbia’s Venture Lab for seven years where I spun-out 70+ technology start-ups based on university research.

One of my latest projects is the Startup Genome, where, in partnership with the Kauffman Foundation and Endeavor Global, we we are mapping the entire world’s early-stage investment and entrepreneurial ecosystems.

My personal blog, www.davelerner.com, explores the worlds of university entrepreneurship, angel/venture investing, and startups and I’m a frequent contributor to multiple publications including Amex OPENForum, Forbes, peHub, and Business Insider, whose SAI group recently named me both one of the “top 100 most influential New Yorkers in the digital business community” and “one of NYC’s top 100 early stage investors”.

I’m an active organizer of entrepreneurship and venture capital events and serve on the Board of New York Tech Meetup, a non-profit organization I am proud to say is now 40,000 techies strong!
