I received an offer from a medium-sized startup recently. The overall package is comparable to my current job but the equity grant is based on a recent round that might have just been finalized, and is not publicly announced yet.The latest round roughly 10x the valuation from last round six month ago. The valuation can be inflated because it is a crypto startup. The investors clearly wanted to get in, but I am worried about taking the same risk as a new employee.Any advice on- how to negotiate the equity grant? Have people seen startup offers to be based on previous valuations instead of the current valuation, assuming the fund raising is super recent. (Of course, I am not thinking about the valuation from six month ago, but I assume there are reasonable recent valuations before the current round)- If I can't negotiate up the equity grant, should I hold off from joining for a couple months? My thinking is that the valuation is unlikely to go up even more in the short term, but maybe it is irrational to think that the risk for joining a startup is highest right after fund raising.
