Early-stage acquisitions usually involve an employment agreement for the founders.
I think the offer I was presented is below market value, but when coupled with the purchase price it seems like a moot point.
Should I put up a fight? Does the acquiring company have the right to discount my salary because they're already paying for the company?
I have personally taken less than market value. I would never do that again. I would suggest that a founders value is much higher to the acquiring company than it is to the market. Hence a higher market value. On the other hand you are worth what you negotiate. Their job is to negotiate the best deal for themselves.
Make sure that there are escape clauses if your liquidity depends on a promised liquidity event. Mine has not happened yet and may never happen. Also if earn outs depend on anything outside of your control make sure that if those events don't happen your earn out goals are adjusted accordingly. We missed an earn out by less than 10% . The acquiring company did not sign deals they committed to signing that would have facilitated at least 30% toward the earn out. Ouch.
