The agreement has a blank for the most meaningful term: the valuation cap. If you raise a round below that cap (or just above it) the SAFE ends up being a good deal. But if you raise the next round at a valuation significantly higher than the valuation cap, you could take a haircut. For example, a $1MM cap that's followed by a $15MM pre-money valuation at the Series A would give SeedRamp a 93% discount on their equity. That's the risk.

TLDR: No way to tell what they might get for their investment until they offer you a valuation cap (and even then it still depends on the future valuation put on the company by the next equity round).
