I think 1% to even 0.5% is pretty likely - at which price maybe you might have to accept something maybe 15-20% below market. I would love to see early developers at this stage get 2-5%, though I think that would be hard for some to push all the way through (past the CEO if applicable, board who has to sign off on the cap table and doesn't want the option pool to be too low too soon, etc).

But would it be fair if you are good and putting in that much work? Hell yes. But likely you're good, and hopefully the work/life balance isn't that lopsided either. Are you going to get it? Unlikely.
