We'd like teams to make as much progress as possible during the 8-weeks of the fellowship. If you have a prototype, that would mean launching and getting your first customers. If you're at idea stage that would mean building a prototype and talking to users. At the end of the 8-weeks we hope the teams will be ready to apply for YC W16 (it's not a requirement -- but we'll encourage it).
What kind of progress do you expect founders to make by the end of the Fellowship? Put another way, if the goal of participation in Y Combinator is for companies to build enough traction to become top-tier candidates for an institutional fundraise, what is the outcome that participants in the Fellowship should hope to achieve?
