I'm about to go start a venture with a partner and was wondering about equity.
Here's the backstory:
It's his idea and he has already programmed 70% of a working prototype. The idea was submitted and accepted at a YC-like (but not YC) accelerator...and will thus receive a good amount of funding.
Through mutual contacts, they reached out to me as he needed more tech talent and help. I'm an experienced developer and have created a few cool projects in the past. Obviously, it's a great idea in a very early stage and the more people we have working on it the better. Not to mention the whole focus on co-founders performing better.
We've met and talked about the idea and I'm likely going to come on board as a co-founder just a couple of weeks before the program begins, with the approval of both the original founder and the program directors.
It all sounds great but I wanted some expert opinions (maybe even people who have gone through YC or TechStars, etc) as to how equity is supposed to work out.
Right now, he wants me to take 10%. Most of the people I've talked to believe I should ask for more. But assuming that's correct, what's "more"? Is it 15, 20, 40, 50? Should I just accept this? What worries me is that the real work and development will occur during this program. Even with the prototype, it's unlikely that I'll only put in 10% of the total effort.
I honestly don't know what to do. Any tips?
