Send a SAFE Terms of Use

Last updated June 26, 2026
The Send a SAFE tool (“Send a SAFE”) was created by Y Combinator Management, LLC and its affiliates (collectively “YC”, “we”, “us” and/or “our”) to help founders enter into simple agreements for future equity (“SAFEs”). SAFEs have been used by countless startups since 2013 to raise money from investors for early-stage fundraisings and are intended to be flexible, balanced and simple to use. More information about SAFEs can be found here.
Send a SAFE is a service operated by YC. These Terms of Use (the “Send a SAFE Terms”) govern your access to Send a SAFE, the Send a SAFE website at www.ycombinator.com/safe (the “Send a SAFE Site”), SAFEs, and related services (collectively, the “Services”).
Use of the Services is also subject to the Y Combinator Terms of Use available at www.ycombinator.com/legal#tou (the “YC General Terms”) and Send a SAFE Privacy Policy available at: www.ycombinator.com/safe-privacy-policy.html, which are hereby incorporated by reference into these Send a SAFE Terms. For purposes of the YC General Terms, the Services are deemed part of the “Site”. To the extent there is a conflict between these Send a SAFE Terms and the YC General Terms, these Send a SAFE Terms will control with respect to the Services. By accessing or using the Services, you agree to be bound by the Send a SAFE Terms and the YC General Terms, including the conflict of law and jurisdiction provisions contained in the YC General Terms. If you do not agree, do not use the Services.
THE YC GENERAL TERMS CONTAIN AN ARBITRATION AGREEMENT, WHICH WILL, WITH LIMITED EXCEPTION, REQUIRE YOU TO SUBMIT CLAIMS YOU HAVE AGAINST US TO BINDING AND FINAL ARBITRATION. UNDER THE ARBITRATION AGREEMENT, (1) YOU WILL ONLY BE PERMITTED TO PURSUE CLAIMS AGAINST YC ON AN INDIVIDUAL BASIS, NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS OR REPRESENTATIVE ACTION OR PROCEEDING, AND (2) YOU WILL ONLY BE PERMITTED TO SEEK RELIEF (INCLUDING MONETARY, INJUNCTIVE, AND DECLARATORY RELIEF) ON AN INDIVIDUAL BASIS.
The Services include, without limitation, a mechanism to sign the SAFE financing documents found at https://www.ycombinator.com/documents, including related side letters (collectively, the “SAFE Documents”), track the signature status of the SAFE Documents and send the final signed SAFE Documents via email to the participating parties (such other party, the “Counterparty” and such email, the “Confirmation Email”). For more information about using the SAFE Documents, please refer to our SAFE User Guide found here . YC may modify, suspend, discontinue or limit access to any part of the Services at any time, with or without notice. The Services are experimental, and features may change frequently. The Services are provided free of charge for all users.
You will only use the Send a SAFE Site for the Services. Every time you use the Services, you represent and warrant that: (1) you are of legal age (18 years of age or older or otherwise of legal age in your resident jurisdiction) and have authority to agree to these Send a SAFE Terms on behalf of your company or business, as applicable; (2) you will not use the Services to enter into any transactions with a Consumer (as defined below); and (3) you are not, and will not when using the Send a SAFE Site, be located in, under the control of, or a national or resident of, a U.S. embargoed country or territory, and are not a prohibited end user under any trade restrictions with the U.S. You are not permitted to use the Send a SAFE Site if you cannot make all of these representations, and you are therefore prohibited from using the Services.
You are required to submit data, text, or other information to the Send a SAFE Site to use the Services (“Inputs”). You represent and warrant that you have all necessary rights to provide such Inputs and your Inputs do not violate any law or third-party rights. You acknowledge and agree that: (1) you have exclusive control of and responsibility for the content of your Inputs, (2) you are solely responsible for ensuring that the documents, agreements or contracts you use with the Services are accurate, complete and reflect your desired Inputs; (3) you are solely responsible for reviewing the legal implications of entering into the SAFE Documents with the Counterparty, including but not limited to the implications of issuing or purchasing securities; (4) you and your Counterparty have exclusive control and responsibility for any documents signed through the Services, and you acknowledge and agree that, regardless of any actions taken by your Counterparty, YC will not be liable for any losses incurred as a result of your use of the Services, except to the extent such liability cannot be lawfully excluded under applicable law; and (5) you are solely responsible for keeping a record of all documents entered into using the Services, and YC is not responsible for providing you a record of signed documents outside of the Confirmation Email.
The Services are built to facilitate early-stage fundraising between startups and their investors and are not built to facilitate transactions that are primarily used for personal, family or household purposes. As such, you acknowledge and agree that consumer protection laws or regulations may impose specific requirements for electronic transactions involving a Consumer. “Consumer” (as defined by 15 USC Ch. 96 E-Sign Act) means an individual who obtains, through a transaction, products or services which are used primarily for personal, family, or household purposes, and also means the legal representative of such an individual. You are responsible for determining whether a Counterparty is a Consumer, and you represent and warrant that you are not using the Services for transactions with Consumers.
By submitting Inputs, you hereby grant YC a nonexclusive, worldwide, royalty free, fully paid up, transferable, sublicensable, perpetual, irrevocable license to copy, display, upload, process, perform,
