Issue & sign SAFEs for free. No DocuSign required.
Manage your SAFEs without the friction. Just enter your details, and Mantle handles the rest—from generating the YC template to managing e-signatures. No DocuSign subscription required. Once signed, your cap table updates automatically. Keep your burn low and your equity organized from day one.
Picture this: your first investor just said yes. You're riding high. This is the moment you've been grinding toward for months.
Then someone says, "just send over the SAFE agreement."
And just like that, the high evaporates.
You open a new tab. Then another. Then five more. You're Googling "YC SAFE template," watching a YouTube video from 2019, texting a founder friend at 11pm asking if they used a lawyer for this. You're not sure if you need the pre-money or post-money version. You're not sure if you're supposed to fill in the valuation cap yourself or leave it blank. You're not sure if you need a lawyer to review it (and if you do, how much that's going to cost).
You get the document sorted. Now you need DocuSign. You sign up for a free trial, realize it requires a credit card, and decide to just figure it out later. You email the PDF to the investor. They ask a question. You answer. They ask another. A week passes.
The SAFE gets signed. You exhale.
Then you remember: you still have to update your cap table.
We built Mantle SAFEs because that experience is completely unnecessary, but it's happening to thousands of first-time founders right now, at exactly the moment they should be celebrating.
Here's what changes with Mantle: → YC SAFE templates built in → E-signatures handled inside Mantle, no DocuSign subscription needed → Cap table updates automatically the moment the SAFE is signed → Full document history and audit trail in one place → Free to use
From "want to invest?" to a signed SAFE in the same afternoon.
