SAFE Agreement

A SAFE Agreement in the United States sets out the rights, duties and consideration binding the parties to it.

The Securities and Exchange Commission (SEC) treats SAFEs as securities under the Securities Act of 1933, 15 U.S.C. § 77a et seq. The SEC's 2017 Investor Bulletin confirmed that SAFEs are investment contracts subject to federal securities regulation under the Howey test established in SEC v. W.J. Howey Co., 328 U.S. 293 (1946). Startups issuing SAFEs must either register the offering with the SEC or qualify for an exemption — most commonly Regulation D, Rule 506(b) or Rule 506(c), or Regulation Crowdfunding under 17 C.F.R. § 227. Rule 506(b) permits sales to up to 35 non-accredited investors and an unlimited number of accredited investors but prohibits general solicitation. Rule 506(c) permits general solicitation but limits sales to accredited investors whose status the issuer has verified through reasonable steps.

Y Combinator revised the SAFE in October 2018 from a pre-money to a post-money structure. The post-money SAFE specifies that the valuation cap reflects the company's capitalization after accounting for all outstanding SAFEs, which makes the investor's approximate ownership percentage at conversion determinable at the time of signing. A $500,000 SAFE with a $5 million post-money cap represents approximately 10% ownership at conversion, regardless of subsequent SAFE issuances. This transparency was a significant improvement over the original pre-money structure, where the founder and investor had to model multiple scenarios to estimate dilution.

A SAFE converts into preferred stock — typically the same series as the lead investor in the triggering financing round — upon a qualified equity financing, which the agreement defines by minimum round size (commonly $1,000,000 or $2,000,000). The conversion price is the lower of the price per share determined by dividing the post-money valuation cap by the company's fully diluted capitalization or the product of the discount rate multiplied by the Series A price per share. Most favored nation (MFN) provisions in SAFEs without a valuation cap allow the investor to adopt the more favorable terms of any subsequently issued SAFE.

SAFEs are used across a broad spectrum of U.S. startup ecosystems: Y Combinator, Techstars, 500 Startups, and most other accelerator programs use SAFE-based seed financing as their standard investment structure. Angels, family offices, and micro-venture capital funds have widely adopted the post-money SAFE as the dominant seed-stage instrument, displacing the convertible note in most Silicon Valley, New York, and Austin early-stage financing markets.

A SAFE Agreement is needed by U.S. startups and their investors whenever seed or pre-seed capital is raised before the company is prepared to set a valuation and issue priced equity. The instrument's design addresses the core tension of early-stage financing: investors want certainty about their future ownership percentage while founders want to avoid setting a binding valuation before the company has developed meaningful revenue or product traction.

Pre-seed and seed rounds by early-stage startups are the canonical SAFE use case. A founder raising $250,000 to $2,000,000 from angel investors, friends and family, or seed funds in advance of a Series A priced round uses SAFEs to document each investment without negotiating a full set of equity financing documents (certificate of incorporation amendment, stock purchase agreement, investor rights agreement, voting agreement, right of first refusal agreement) for each small check. The SAFE documentation is a single four-to-six page agreement that can be signed and closed in hours rather than weeks.

Accelerator program investments are standardized as SAFEs. Y Combinator invests in participating companies through post-money SAFEs with a $500,000 cap (for the standard batch check), and alumni companies frequently use SAFEs for subsequent seed financing using the YC standard form. Techstars programs use convertible notes, but the broader startup community has largely standardized on YC's SAFE for speed and simplicity.

Bridge financing between priced rounds — where a company needs additional capital before a planned Series A or Series B but has not yet completed the conditions precedent for the larger round — is efficiently documented with a SAFE rather than a new convertible note or equity instrument. The bridge SAFE can include an MFN provision ensuring the bridge investor captures the same terms as the anticipated priced round.

Strategic corporate investors making small investments in startup partners or suppliers sometimes prefer SAFEs over more complex minority equity investments because the SAFE does not give the investor governance rights, information rights, or registration rights that would create ongoing administrative obligations for both parties.

Founders should issue SAFEs through their Delaware C corporation or through a qualified legal entity (not as a sole proprietorship) and should maintain a SAFE tracking spreadsheet recording every investor's name, investment amount, valuation cap, discount rate, and MFN status, so that the fully diluted cap table at Series A conversion can be calculated accurately.

A complete SAFE Agreement for U.S. startups must address the following provisions to create a legally enforceable, SEC-compliant instrument that accurately reflects the parties' economic agreement.

The purchase amount and investor identification clause identifies the investor by full legal name (individual or entity, with state of formation for entities) and states the dollar amount the investor will pay in exchange for the SAFE. The agreement should also state the date of execution and the name of the issuing company (full legal name, state of incorporation, and principal place of business).

The valuation cap defines the maximum company valuation — measured on a post-money, fully diluted basis under the current YC post-money SAFE standard — at which the SAFE will convert in a qualified equity financing. A $10 million valuation cap means the investor's conversion price will not exceed the price per share derived from a $10 million post-money capitalization regardless of the actual Series A valuation. The valuation cap is the investor's primary economic protection.

The discount rate provides an alternative conversion mechanism for SAFEs that include this feature. A discount rate of 80% means the SAFE converts at 80% of the Series A price per share, giving the SAFE investor a 20% discount as compensation for earlier risk. The conversion price is the lower of the cap price and the discounted price — whichever gives the investor more shares.

The most favored nation (MFN) provision applies to uncapped SAFEs without a valuation cap. The MFN clause requires the company to offer the SAFE investor the right to adopt the terms of any subsequent SAFE issued on more favorable terms (specifically, a lower valuation cap or higher discount). The MFN notice must be given within five business days of the subsequent SAFE closing.

The pro-rata right allows the SAFE investor to participate in the equity financing round in which the SAFE converts — up to the investor's pro-rata share of the round based on the investor's anticipated ownership percentage. This provision ensures early investors can maintain their percentage ownership through the Series A by purchasing additional preferred stock at the Series A price.

The conversion events section specifies the three triggering events: (1) Equity Financing — a bona fide financing round of at least the minimum size specified, in which the company issues preferred stock to investors; (2) Liquidity Event — an acquisition, merger, or change of control of the company, or an IPO; and (3) Dissolution Event — the company winds down, assigns assets for the benefit of creditors, or a court orders liquidation. Each event triggers a different conversion mechanism with different economic outcomes for the SAFE investor.

The representations and warranties section contains the company's representations that the SAFE is duly authorized, that the company is validly existing in its state of incorporation, and that the equity to be issued upon conversion will be validly issued, fully paid, and non-assessable. The investor represents that they are an accredited investor under Rule 501 of Regulation D, that they are acquiring the SAFE for investment purposes, and that they have had the opportunity to review the company's financial information.

The Regulation D exemption and securities law compliance provisions include the company's representation that the SAFE is being offered in reliance on an exemption from SEC registration, the investor's representations supporting that exemption (accredited investor status, investment intent, no general solicitation), and the restriction on transfer of the SAFE or the equity received upon conversion except in compliance with applicable securities laws.

The governing law and dispute resolution clause specifies the state law governing the agreement (typically Delaware or California) and whether disputes are resolved by arbitration (JAMS or AAA rules) or in state or federal court.
