I need an co-founder (php mysql programmer).

[constantin]

I want to submit to Ycombinator my startup but i don't have a good programmer. I give 7% equity.

Wow! 7% for the person who actually creates the start-up. Generous to a fault I would say.

[constantin]

Which to be the correct amount?

[pknight]

( 100% - Investor equity ) / number of founders

[bdfh42]

A very good start point I would say.
