How much equity should I get as a first engineer?
I joined a start-up fresh out of university as the first employee with a non-technical founder, taking (at the time) at least 25% less than my market rate. At the time, I settled for it because it is a project I was really excited about and it was a great portfolio building opportunity for me as a developer, and I was quite empathetic to the financial situation. My contribution to the company can be said to be the backbone of it, but the founder denied me the title of co-founder on the basis that I was drawing salary while he is funding the company out of his pocket. We're at seed funding right now and he's only giving me 1%. But without me, the product wouldn't be half of where it is today.
The general sense I get is that because I am young, my opportunity cost is lower and he's using that as an excuse to give me less equity. My value to the company is plain to see because I've built something that everyone (other developers, investors, potential customers) is amazed by, but I have no numbers to quantify my value to the company because we are not making money yet (due to other factors that I have no control over). I have a colleague in my boss's other company who is in a similar situation: young, low market rate, huge contribution to the company, only given 1%, no cofounder title. It's pretty clear to me that he's lowballing me and I'm pretty set on leaving, but I do want to know how much someone in my situation (young but huge contribution) should get, because I haven't read about it anywhere. Appreciate your input :)
