How to Issue a SAFE: A Step-by-Step Guide for Founders

Signing modal with L. Hamilton's signature

For most founders, issuing a SAFE used to mean the same painful “Early Stage Shuffle”: agree on terms with an investor, hunt down a template, pay for a standalone e-signature tool, and then (if you remember) manually update your cap table spreadsheet.

It’s fragmented, it’s slow, and it usually costs you a monthly subscription fee you don’t really want.

That workflow is officially a thing of the past. If you’re wondering how to issue a SAFE quickly and without the overhead, Mantle now has free SAFE issuance and e-signing built directly into the platform.

Here’s your complete step-by-step guide on how to issue a SAFE using Mantle’s integrated worfklow.



1. Set up a Mantle account

If you’re not already on Mantle, you can create your free Mantle account here. Signing up takes just a few minutes. No credit card required.

2. Create a SAFE draft

Navigate to Mantle SAFEs to begin issuing your SAFE. You’ll enter stakeholder details (name, email address) and fill out the key SAFE terms, including:

3. Select your template

One of the most common headaches when issuing a SAFE is tracking down the right template version. With Mantle, you have instant access to standard YC SAFE agreement templates, including:

Need a custom template? You can upload your own on any of Mantle’s paid plans.

4. Send for e-signature

This is where the old way of issuing a SAFE usually got expensive. Instead of exporting the SAFE agreement to a third-party signing service like DocuSign, you can send the SAFE directly through Mantle — for free. Your investor receives a secure link via email and can e-sign in just a few clicks.

5. Watch your cap table update automatically

Once the final signature is collected, your cap table updates automatically inside Mantle.


Bonus: Model your SAFEs before you issue

Before issuing a SAFE, it’s worth stress-testing the terms. Mantle’s Scenario Modeler lets you input round assumptions and SAFE details to generate a pro forma cap table, so you know exactly what you’re signing before anyone else does.
