1) Is there any process for investing in a company already incorporated in Canada? Could we apply with the assumption we would move it over to the US if accepted?
2) Would YC consider applications for a team with an existing early-stage product on the market?
2) yes. there are several companies on the current round who applied when they had both a launched product and were also already generating decent revenue.
Many YC companies already have products on the market.
18 months on we still don't have visas as we haven't found it necessary to be based in the US - or not important enough to subject ourselves to the expense and distraction of the visa application process. We come and go from time to time on VWP. Only now the company's becoming more solid will we look at obtaining visas.
