Binderwork and YC's Send a SAFE
Y Combinator's Send a SAFE fills in YC's forms and emails them for signature, for free. Binderwork uses the same forms, word for word, and keeps the round around them.

Where Send a SAFE is better
- It is Y Combinator's own tool for its own forms, and investors know it.
- It takes about two minutes, by YC's count, for a single SAFE.
Where Binderwork is different
- The board consent before SAFEs go out, a closing checklist and the register, in one place.
- Executed SAFEs go into your cap table, with the deck, NDAs and approvals beside them.
- Prepare a round from ChatGPT or Claude; nothing goes out until you approve it.
Moving from Send a SAFE
- Keep using Send a SAFE if you like it: import the executed SAFEs into Binderwork's register, and Binderwork reads YC's forms by their own words.
