Room 77 iPhoneThe Launch conference, entrepreneur Jason Calacanis’ event for launching startups and products, just wrapped up in San Francisco, and the award winners have been announced.

There were a bunch of different categories, but three companies walked away with wins. Room 77, the new search and recommendation tool for hotel rooms, won the prize for best company launching for the first time. StackOverflow, the programming Q&A site that just launched a programming jobs service, won the prize for best existing company launching a new service.

And GreenGoose, the company that uses stickers to turn exercise and healthy eating into a game, won the prize for best company that was plucked from the demo pit. The company won an even better prize on-stage — the judges, who are also investors, have already committed about $500,000 in funding.
