IMPORTANT: The original YC founders are no longer involved with this…

Y Combinator funded AppJet is an online programming tool for building simple web apps. Founded by former MIT students, AppJet intends to simplify the process of writing web applications. The applications are programmed on a web based text editor in the simple but powerful JavaScript programming language. JavaScript is used on both the server and client side. They've included several bundles of code libraries for databases and more importantly interfacing with the Facebook API. In order to efficiently host users' applications, AppJet has developed their own application virtualization system. The system allocates processor time to active applications and cuts off greedy ones after running an alloted number of compiled lines of code to prevent abuse.\n\nAppJet as a dev platform seems no longer to be active. There are some legacy downloads available, however.

Building the next Procore

Hello, Chair Inc. was founded in 2006 by Luke Iannini, Mike Jacobs and Kevin Corcoran to explore opportunities in applied machine learning and internet advertising. After receiving funding from Y-Combinator in 2007, we produced Adpinion, one of the first advertising networks to utilize user feedback to drive personalized targeting.\n\nOur core technology — the recommendation engine called SparseReduce — has since proved infinitely adaptable in such diverse problem domains as Amazon product recommendation, eBay auction discovery, image and language comprehension, and Twitter stream exploration.\n\nThe latest application of SparseReduce is Appsaurus, an app discovery platform which was released on the eve of 2010 to overwhelming critical acclaim.\n\nWe're backed by some pretty incredible investors: Harrison Metal, Mitch Kapor, Chris Sacca, Y-Combinator and David Parker to name a few. We're also proud to have Alexis Ohanian as an advisor.
