Deciding on a Startup offer (from a friend)
I have a friend who is in charge of product definition and programming in a start up. It has 4 founders, 2 programmers and 2 business people. They just got seed money so they are looking to expand their programming team by 2 programmers initially. I like their idea and the other guys are pretty friendly and smart.
They gave me an offer of $80K plus 0.3% of their company with 4 year vesting. I am well-versed at the Microsoft stack so I should be able to hit the ground running. I am also making $110K. Another friend gave me the equation of ($110-$80) * 4 / 0.003, which makes $40M as the breakeven point. The valuation seems really high. Is that a good measure of how to value my offer? What should I consider when deciding on my counter-offer?
Thank you very much for your advice.
