My example:
Day 1: I installed the security cameras in the new office
Day 50: I surveyed customers
Day 200: I wrote all our code
Day 500: I wrote the grant proposals
Day 800: I pitched to investors
Now I have hired people to do all of those things and I mostly just manage them.
I was in the same position as you and took 24%. As a new founder I had no idea what the CEO was going to do while I was writing code, but looking back, I’m glad we split the equity the way we did. My co-founder CEO did some amazing selling and I’m super happy with my 24%. There were actually 4 of us and we split it nearly equally between 2 engineers and two business side. In the old days, I think engineers got less, but more and more we are expected to have more business savvy like CTOs and so you kind of grow into that role and definitely earn your 24%.
