I am adding a Sales and Marketing co-founder for my start up. The product is already developed and we have 3 unpaid customers so far (Private Beta). My co-founder will work full time on this venture to get customers and do online marketing as well. He is ready to work on a vested equity for an year or two. I would like to start with X% of incremental equity tied to his performance.
My question is how much and what basis I should offer him equity?
Additional information: 1. I spent more than 9 months to develop this product, including product conceptualization, customer development and Beta testing 2. I spent more than $20 K out of my own pocket 3. I will continue to spend 20 hours per week to support the technical and operations side of the business 4. My co founder will spend 40 hours a week.
