Dustin Moskovitz, left, and Justin Rosenstein
In this photo taken Thursday April 26, 2012, Dustin Moskovitz, left, and Justin Rosenstein, right, co-founders of the collaborative software company Asana, pose outside of their offices in San Francisco. Facebook co-founder and former Mark Zuckerberg roommate Dustin Moskovitz is by many accounts the world’s youngest self-made billionaire. But the 27-year-old isn’t sipping champagne in the Caribbean. Instead he’s thrown himself back into San Francisco’s startup churn with an online collaboration app he says will become the world’s next $100 billion company.
