This spreadsheet serves as a Data Room that you can share with your team and investors after signing a term sheet. Having all diligence information and documentation prepared and collected ahead of time can cut as much as a week off of your closing process.
Adapted from a checklist published by Aaron Harris in YCombinator's public Fundraising and Series A libraries. Originally created by Jason Kwon, former GC of YC Continuity, after being involved in "hundreds of financings with nearly every law firm and VC fund in the valley."
