I'm sure I'm not the first person to ask this, and know each case is individual, but what guidelines should one use?
I'm the third person, and my percentage is pretty low (low single digits). I came in pre-money, and I accepted the percentage given because (1) I was fine with the salary offered (deferred until funding) and expected money to come imminently (it took a bit longer, but we're getting customer revenue) and (2) realized I didn't have the full picture (how many points were in the option pool, saved for legal counsel, etc.) and couldn't evaluate what a fair share was.
It looks like funding is coming via customer revenue about... now. We'll be incorporating soon, which seems like a convenient time to revisit the equity question. I don't feel entitled to a 1/3 split, since the other two guys have been working on the project a lot longer than I have, but I did come in 7 months pre-money, so I feel entitled to all the trappings of founder status, and an equity share that would reflect that.
What's a good guideline for whether or not I'm getting a fair share? Is it wise or unwise to negotiate a higher share, and at what point (pre- or post-revenue)?
Also, how do board seats work? If I enjoy hacking more than business, do I want one, and how do I go about determining if I deserve one? (E.g., if there are 3 board seats, I don't feel entitled to one; if there are 5+, I'll be pissed if I don't get one.)
I'm assuming you don't mean that you get paid back for salary you didn't get paid before funding. FWIW, investors are REALLY not keen to give $ to a startup and have a big slice of it go to to back-earnings.
Onto the question/situation, though. How long did they work on it before you? Do you all work the same amount?
Depending on the answer to those questions, I think you're entitled to a close to even share, assuming you all vest.
A way to get around the inevitable response is to vest. If you want to own 25% of the company, suggest that it vest over 3 years (you should ALL be vesting anyways). A good way to pitch it is this: "You guys have been working on this for 12 months. I've been working on it for 7. By the time I vest, the difference will be 41 months versus 36 months of time in. What do you think a reasonable percentage of my contribution will be at that point?" If time is the only facture, that's a fair point. If they poured cash in, have amazing connections, or had higher paying careers they set aside, they might be entitled to more.
Regarding board seats, those get re-assigned if you get funding oftentimes. Board meetings aren't particularly fun-- I'd avoid it unless you think your board will do something screwy. Only thing I'd offer is that you want founders to have control of the board-- if not, the board can fire the founders. If you are the odd-man-out, the board can fire you whether you are on it or not. So being on it offers little protection unless you have unanimity clauses written in. You can always ask to have regular optional attendance for the board meetings.
