On top of that, let's assume an investment in the seed round is made via SAFE and the share price at that stage is $0.15. In the Seed round, a priced investment comes in and the new share price is $3. In this case, is the investment from the Seed round going to get the value of the $0.15 or of the $3?
Yes, investing via a SAFE (Simple Agreement for Future Equity) means that the investment won't have a set valuation until a future priced round - there is also no share price set during a seed round comprised of SAFEs.
The valuation (and thus price per share) is essentially deferred until more information is available, typically at the time of a preferred stock financing. The SAFE then converts into equity, usually preferred stock, at the predetermined terms, which often include a valuation cap or discount rate.
