Working for a startup on its way to seeming success and I’m trying to figure out my overall position.

Is there a way to estimate company valuation based on seed rounds, especially Series B. Is it something like 5x series B funding is approximate valuation?

I know it’s difficult to determine without seeing how much equity was given in exchange but didn’t know if there was an industry estimate.

We just pulled $75 mil in Series B and interested to know where the company stands.
