I'm a co-founder of a new startup with two other partners. I'm a designer and they are a developer and biz dev guy respectively. We are in the initial prototyping phase for the project and will be rolling out a private beta version in the next month or two. My partners are both ready to make this their full-time work, despite there being no funding yet. I, on the other hand, have very significant work commitments and am not ready to work on the startup in a full-time capacity. In other words, I'm hedging. I'll be designing the project and doing all front-end development, but will probably only be able to offer between 10-20 hours per week on the project.
So, here's the question: considering I am a founding member, have been heavily involved in the conception and will be functioning (for the time-being) as lead designer - what would be an appropriate share of equity (with the 2 other partners full-time and holding equal equity). Are we talking 5% or 25%?
We'll be signing an operating agreement based on these terms shortly.
