Comparing Pre-Money SAFE and Post-Money SAFE

Syndicately blog cover card

One of the simpler methods for early-stage startups to secure funding is by utilizing a financial instrument known as a convertible security. A convertible security allows its holder (usually an investor) to transform it into a different asset, such as company shares. A prime example of this is the Simple Agreement for Future Equity (SAFE).

SAFEs have gained popularity among startups for their simplicity compared to traditional equity investments. SAFE agreements involve fewer complexities.

What Exactly Is a Pre-Money SAFE?

A pre-money SAFE represents a contract between an investor and a startup, outlining the specifics of a convertible security that will be converted into equity under predetermined conditions.

Here’s how a SAFE typically functions: an investor provides capital to a company with the expectation of receiving equity (shares) at a later date. However, at this initial stage, no valuation is set to determine the quantity of shares or the price at which they will be issued.

In the case of a pre-money SAFE, each new SAFE holder dilutes the ownership of existing shareholders, including the founders. This uncertainty regarding ownership percentages prevails until a new financing round occurs. To illustrate this process, let’s delve into an example.

Challenges with Pre-Money SAFEs

Initially, pre-money SAFEs posed two significant challenges. The creators of SAFEs at Y Combinator identified these issues:

  1. Investors lacked clarity on the percentage of equity they could expect to receive.

  2. Startups struggled to foresee the dilution resulting from pre-money SAFEs.

To address these concerns, the post-money SAFE emerged.

Post-Money SAFE: An Explanation

The post-money SAFE differs from its pre-money counterpart and aims to resolve the previously mentioned challenges. The primary distinction lies in how investors secure a specific equity percentage relative to other shareholders, including fellow SAFE investors. This is achieved through the application of a post-money cap, which takes into account all investments within the “SAFE round.”

Understanding the post-money cap is vital. It covers the entire SAFE round, not just the equity round triggering the conversion.

In a post-money SAFE, the company’s capitalization includes the pre-conversion capitalization (shares owned by founders and other stakeholders before conversions) plus all the shares issued during SAFE conversions. This calculation helps investors and founders determine their ownership percentages in relation to other stakeholders before the new financing round that triggers the conversion.

While the upcoming financing round will dilute SAFE investors to some extent, they will have a clearer understanding of their ownership percentage compared to when pre-money SAFEs are used.

Comparison of pre-money and post-money SAFEs on the effect of each new SAFE holder, investor clarity on ownership, and how founders see dilution.
A post-money SAFE lets investors and founders work out ownership percentages before the round that triggers conversion.

Pre-Money SAFE vs. Post-Money SAFE

A post-money SAFE fixes the investor’s ownership percentage when it is signed, so both sides can see the effect before the priced round arrives. A pre-money SAFE leaves that percentage unresolved until conversion, which is what makes the dilution harder for a founder to plan around.
