Codeacademy has just launched its program for APIs for open release. The well known Codecademy is a team of hackers working hard to build a better way for anyone to teach, and learn, how to code. Their investors have been Union Square Ventures, Index Ventures, Kleiner Perkins, O'Reilly, SV Angel, Thrive Capital, CrunchFund, Collaborative Fund, Founder Collective, Yuri Milner, Vivi Nevo, Richard Branson, and several others.
A good API is the secret to being able to test earlier, which means finding problems earlier in the software process. Perhaps earlier enough to prevent the delays, certainly earlier enough to save time. If you want to test earlier and be more effective, this is the place to start.
