Topcoder

"The strategic innovation of the topcoder community (Topcoder Crowdsourcing Solution) enabled us to go hard and go fast out-of-the-gate, executing our vision to simplify and enhance everyday experiences on a modest budget. The quality of work was top notch and everything that was promised was delivered, if not exceeded."

"Crowdsourcing has been a force multiplier for SunShot Catalyst – a $1M prize program on a lean operational budget. By sourcing solar ideas, we have been able to capture the collective genius of a growing ecosystem of solar innovators. There are over 5000 active members in the Catalyst community from 54 countries with the majority of participation from the U.S. We have also raised the bar across the U.S. Federal Government for what can be accomplished with crowdsourced software development of rapid prototypes."

"Topcoder surpassed expectations: a two-week competition led to code that was just as good but almost three orders of magnitude faster for a few thousand dollars. Hard to imagine beating that."
