About Me

I'm a 3x Entrepreneur, Angel Investor, Blogger and host of Venture Studio where I engage with entrepreneurs, investors, founders and other vibrant members of the flourishing New York entrepreneurial ecosystem and beyond. 

I'm also Adjunct Professor in Entrepreneurship at Columbia Business School as well as the Director of the Venture Lab at Columbia University Tech Ventures where I've spun-out 70+ technology start-ups based on university intellectual property over the last six years.

My personal blog, www.davelerner.com, explores the worlds of university entrepreneurship, angel/venture investing, and startups and I'm a frequent contributor to ForbespeHubHuffington Post 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, serve as a mentor to entrepreneurs and start-ups in and outside of the university arena, serve on the Board of New York Tech Meetup, as Resident Venture Advisor and Board Member to the Lang Center for Entrepreneurship at Columbia Business School, and as a Board Member of both the New York Venture Community and Columbia Venture Community

One of my latest projects is the Startup Genome, where we are mapping the entire world's early-stage investment and entrepreneurial ecosystems in a visually pleasing, crowdsourceable format.
