Simple Agreement for Future Equity (SAFE)

A Simple Agreement for Future Equity (SAFE) gives an investor rights to future shares in exchange for capital paid immediately. It carries no interest or fixed maturity and converts into shares in a later equity financing under its agreed terms. Start-ups use it to raise early funding without negotiating a full equity round at that point.

The instrument was introduced in the US market by the start-up investor Y Combinator. Key terms may include a valuation cap or a discount to the price of the next round. They determine the price at which the early investor subsequently receives shares. Not every version contains both features, so the particular form governs its economic effect rather than the SAFE label alone.

The main difference from a convertible loan is the absence of ongoing interest and a fixed repayment date. This does not mean the investor has no payment rights. Standard terms provide specific entitlements on a sale or dissolution of the company. Actual recovery depends on available funds and ranking relative to other capital providers.

For founders, dilution is the central practical issue. Several SAFEs issued successively can collectively represent a substantial share of the company. Before further fundraising, the resulting ownership percentages should be modelled across different valuations, including the effect of an additional option pool. Outstanding SAFEs belong in the fully diluted cap table even though their holders are not yet ordinary shareholders.

Investors also need to understand the conversion trigger, treatment of an early exit and any additional information or participation rights. In Germany a US template cannot simply be applied unchanged to every GmbH. Corporate implementation and accounting classification must fit the specific structure. Simple documentation consequently does not remove the need to examine the economic terms and their effect on founders, existing investors and the next financing round.
