SAFE
Simple Agreement for Future EquityA founder-friendly contract that lets investors put in money now and convert to equity later (at the next priced round).
A SAFE is an investment instrument popularized by Y Combinator. The investor wires money today; equity gets allocated later — usually at the next priced round, with either a valuation cap, a discount, or both. No interest, no maturity date, no debt. SAFEs are common for pre-seed and seed rounds in SEA because they're fast to close and don't require setting a valuation.
