The Ledger

Every round is lost in
the same six places.

Due diligence rarely breaks because of the deal itself. It breaks when requests, files, versions, and access are scattered.

BEFOREThe way rounds die
  1. 01Drive folders no one owns
  2. 02Dropbox links pasted in email threads
  3. 03NDAs re-sent by hand
  4. 04Version 4, final, FINAL_v2.pdf
  5. 05Missing docs discovered on the LP call
  6. 06Same 40 questions from every side
AFTERIn DataRoom One
  1. 01One checklist scoped to your round
  2. 02One link with granular per-viewer access
  3. 03Access requests kept with the room
  4. 04Latest version, always. Old ones archived.
  5. 05Missing docs surfaced 3 weeks before the ask
  6. 06Answered once. Reused across every counterparty.
The Method

chaos and closed.
