A simple agreement for future equity (SAFE) is a funding instrument that allows startups to raise capital without immediately issuing shares or taking on debt. Investors provide funds to the company in exchange for the right to receive equity in a future financing round. SAFEs are popular because they simplify fundraising, reduce legal costs, and avoid the complexity of traditional convertible notes. At Angel School, we teach founders and investors how SAFEs can accelerate startup funding while aligning long-term interests.
