SAFE

SAFE stands for “Simple Agreement for Future Equity.” It is a contract between a young company and an investor. The investor pays in money immediately but does not initially receive any shares in the company. Instead, they receive a promise to obtain these shares later. The trigger for this is usually the next major funding round, in which other investors come in and a price is set for the company. This form of contract was invented in 2013 by the US startup accelerator Y Combinator, and today it is standard practice in the tech industry.

Why startups avoid the pricing question

The most difficult point in a company investment is the price. How much is a company worth that has two people, a prototype, and no revenue yet? This can be argued endlessly, and that argument costs months and legal fees. A SAFE simply pushes the question into the future. By then there are user numbers, revenues, and professional investors who negotiate a price.

The second reason is speed. A classic equity investment agreement can easily run to thirty pages and requires a notary. A SAFE fits on a few pages and is often signed within days. For a company whose money will run out in three months, that is a decisive difference.

This speed is especially in demand in the AI sector. Compute time on powerful graphics cards costs a lot of money, often even before a product exists. Many AI startups therefore raise several million early on via SAFEs, long before their first real funding round.

Cap and discount: the two adjustment levers

A SAFE does not set the price, only the conversion rule. Two components almost always appear. The first is called the valuation cap. It establishes the maximum company value the early investor has to reckon with, no matter how expensive the company actually becomes later.

An example: someone invests 100,000 euros with a cap of five million euros. Two years later the company is valued at 50 million. The investor’s shares are still calculated as if the company were worth five million. This turns 100,000 euros into two percent of the company instead of just 0.2 percent. That is exactly the reward for the early risk.

The second component is the discount, typically a 10 to 25 percent reduction on the later price. It’s important to note the difference from a loan: a SAFE has no interest and no repayment date. If the company goes bankrupt, the money is gone. And if a funding round never comes, a SAFE can theoretically remain a promise forever.

Reading SAFEs correctly in startup news

In news about startups, the term usually appears in connection with very early rounds, often called “pre-seed” or “seed.” When a report speaks of a funding round “via SAFEs,” it means: no shares have been transferred yet. The valuation mentioned is then often just a cap, not an actual market price. This distinction is frequently blurred in headlines.

There is a typical trap here for founders. Because SAFEs are so easy to sign, some companies accumulate ten or twenty of them. At the next round, all of them are converted into shares at once. Suddenly the founders own much less of their own company than they thought. Experts call this effect dilution.

In Germany the situation is somewhat different than in the US. Because shares must be transferred via a notary there, many German startups work with an adapted variant, the convertible loan. The basic idea, however, remains the same: money today, shares later.
