I co-founded Vindigo in 1999, which was one of the first and most popular apps for mobile phones in the US. ...
Then I joined the founding team of Two Sigma Investments, which I helped build into a leading investment management company, now with over $50 billion in assets. ...
I'm now mostly retired from Two Sigma and work on personal projects:
Now I'm working on a new kind of chess app.
