I'm experimenting with a couple of ideas to see if one has potential. If so, I might consider applying in October. I've received lunch invites from a couple of investors to chat further, but I don't need the money yet. I believe that I should take investment only after I feel confident that the idea has a good chance of success. I can experiment with ideas on my own; it's much faster and I can change direction quickly if something doesn't look like it's working. If I do apply to YC, it'll be for the community and the support, not the money.
