A startup data room checklist: six folders to build first, what to add at pre-seed, seed and Series A, what to leave out and when to share.

Bottom line: Build the room in six top-level folders: overview, financials, legal, team, market and product. Fill them for your stage: pre-seed rooms are short, seed rooms add traction and projections, and Series A rooms add cohorts, unit economics and contracts. Share the room after an investor shows real interest, not in cold outreach.
