Y Combinator Series AA Equity Financing Docs Back Up

Last Updated on March 25, 2026 by Ryan Roberts

Y Combinator and Wilson Sonsini Goodrich & Rosati are happy to announce the Series AA Equity Financing Documents.

The Y Combinator documents are back up again–grab them while you can.

At first glance, it looks like they added a term sheet. And now each document comes with a fancy new header:
