I create new products, generate innovative business models, and love to solve intractable problems.

I craft business strategies to navigate precarious business environments.

I specialize in guiding early-stage startups into successful businesses: I joined PayPal when our monthly burn-rate was $6 million; I joined LinkedIn, Slide and Square when we had no revenue. Five companies I helped build are now publicly traded with market capitalizations >$1 Billion. Three others have been acquired for greater than $1 Billion or are publicly traded IPOs.

I served on the Board of Directors of Xoom (NASDAQ: XOOM) from 2003 until 2015 and served on the Yelp Board from 2005-2014 (NYSE: Yelp). I have served on the Board of Reddit since 2013. I am a co-founder of OpenDoor and serve as our Executive Chairman.
