Zynga held an IPO (NASDAQ: ZNGA) in 2011 with a $10 billion valuation after reaching $1 billion in annual revenue in just 4 years after its founding. It was the largest IPO since Google (2004) with the fastest growing revenue of any internet company in history.

Waldron left Zynga in October 2013 to focus on angel investing and advising seed stage startups.
