Yes, we absolutely fund companies at the idea stage, and often companies will pivot mid-batch -- in fact, one of our fastest growing startups from last year did exactly that. One of the things I hear most often from our founders is that they accomplished more in their 3 months at YC than they did in the entire year before. Also, keep in mind that press is selective, and some companies wait years before publically launching as a YC company.
