Quantopian reports having 25,000 quants using its system, and recently said it saw more than $100 million in trades in May alone. The final step is to connect the top performers in Quantopian’s community with a dedicated pool of capital. In that way, Quantopian hopes that the financial incentives will attract the best quants to the system, and the startup will be able to generate revenue through fees as well. To help make it all happen, Quantopian is bringing on a Wall Street finance veteran, Rob Stavis, to its board. Stavis is now a partner at Bessemer Venture Partners in New York, which led the Series B round for the startup.
