ABSTRACT
Simple Agreements for Future Equity (or ‘SAFEs’) are now the primary way for early-stage startups to raise capital. By allowing investors to wire cash in exchange for a right to receive preferred stock in a future financing round, SAFEs enable startups to put their investor’s funds to work immediately while deferring the difficult conversations over stock price or investor rights. Other instruments have offered a similar ‘pay now, get shares later’ concept for early-stage investments in the past. But the SAFE, developed and standardized by the influential tech accelerator Y Combinator, packaged it in a way venture markets liked much better.
As the use of SAFEs increased, they also began to appear more frequently in litigation. This paper identifies a recurring analytical difficulty in how courts approach these instruments. SAFEs, it seems, have become victims of their own clever branding. While courts understand that SAFEs are agreements that may provide their holders with preferred stock in the future, they fail to see that SAFEs are not only that. They are financial instruments with economic value independent of the preferred stock to which they may convert. Even before conversion, they are designed to give their holders preferred-stock-like economic claims, deliberately unbundled from the governance rights that typically accompany them. Missing this point, courts have either denied SAFE holders aspects of their economic claim or imposed governance rights they did not bargain for. More specifically, this mistake has led courts to adopt a fraud pleading standard that leaves SAFE holders exposed, to create uncertainty about SAFEs’ classification as debt or equity, and to limit founders’ and investors’ ability to define the duties startup directors owe – and do not owe – to their SAFE holders.
The paper makes three related contributions. It offers a theory of the frictions SAFEs were designed to solve and why they succeeded where earlier deferred-equity instruments have failed, it models how SAFEs deliver ‘stockless preferred stock’ economics, blurring the line between future equity and present equity, and it uses these insights to define and analyze the systematic flaws in the emerging SAFE case law.
