Apply, you lose nothing. And apply again once you get more progress.

There is no ideal stage, but they'll fund the most promissing of them. The more your startup grows and the more times you apply (= persistance and staying alive), the more interesting your startups gets, hence better the odds.

At Quero we applied 3 times before being invited for an inverview and approved.

Thanks for the advice, I think we'll fill out an application and see what happens :)
