News and discussion around startups and applying to Y Combinator.
In 2005, Y Combinator created a new model for funding early stage startups. We invest $500,000 in every startup and work intensively with the founders for three months. For the life of their company, founders have access to the most powerful community in the world, essential advice, later-stage funding and programs, recruiting resources, and exclusive deals.
