Pro Tips
Cap vs. Discount: Compare effective valuations. The better one wins.
MFN SAFE: Use when terms aren't finalized. It gives you the best deal any investor gets.
Pro-Rata Rights: Critical for future rounds. Without it, you can get diluted even if you can afford your pro-rata share.
Early Stage Caps: Pre-money caps are typically $5-15M. Higher caps favor founders.

How SAFE Conversion Works

When a priced round happens, SAFEs convert at the lower of (a) the valuation cap divided by the company's valuation, or (b) the discount applied to the price per share. This gives SAFE investors a better price than the round investors, rewarding them for their earlier risk.

What are Pro-Rata Rights?

Pro-rata rights allow an investor to maintain their ownership percentage in future rounds by investing additional capital. For example, if an investor owns 5% after your SAFE round and you raise a new round, they have the right to buy enough shares to stay at 5%. Without pro-rata rights, their percentage would shrink (dilute) with each new round.
