Carpooling market ?

Hey, I'm working since a while now with one of my talented friends on a carpooling website for both users and companies, with a lot of fancy features, Until there it was only a toy, spent some long nights to talk about it, but now the development began with already some cool stuff even if we are far from the end.

Do you think a "carpooling" market really exists ? Do you know companies that could pay for this ?

Thanks for your feedback, it's my first post on Hacker news, hello world !
