Build your investor data room in an afternoon, then check it: missing, out-of-date and risky files are flagged before an investor opens it. A checklist tool, not legal advice.
Good to know It checks names, dates, sizes and duplicates. It does not read inside documents, so it cannot tell whether your numbers agree; the guide lists what to check yourself. A practical checklist, not legal or tax advice: what investors require varies, so ask your lawyer.

A tidy, current data room makes a founder look prepared and speeds up a raise. A messy one raises questions in the middle of it. Checklists tell you what should be there; this kit also checks what actually is. Point the Data Room Check at your data room folder (a local folder, or a Google Drive, Dropbox or OneDrive folder synced to your computer). For pre-seed, seed or Series A, it reports missing documents and folders for your stage; out-of-date documents, such as a cap table, financials or KPIs older than their limit, with dates read from file names like Cap-Table_2026-09-01.xlsx; files that should not be there, such as passport or ID scans, password files, and secret or key files; and messy ones: "final_v3" names, duplicates, empty files and folders, system files, huge files, and formats investors can't open in a browser. It then writes a private report with a fix for every finding, and a clean index for investors (HTML and CSV) listing every document with its date and size. It never changes, moves, uploads or sends anything. The kit also has a nine-folder skeleton, from 00 Overview to 08 Legal and IP, each with a README of what goes inside, and a guide on how investors tend to use a data room, what goes in at each stage, red flags to fix, sharing safely, and a ten-minute monthly routine. The whole checklist is one file you can edit (stages, age limits, keywords). A practical checklist, not legal or tax advice.
One company's data rooms. Advisers and accelerators working on several companies: email [email protected]. Full terms are in the LICENSE file inside the download.
No. It is read-only and offline: it never changes, moves, uploads or sends anything. It finds documents by words in their file names, so unusual names may need a keyword added to checklist.json.
7 automated tests pass (21 September 2026): a complete seed-stage room with no findings and a messy room with 12 kinds of planted problem, each found; date reading from file names in seven formats, with no false dates from words like "Summary 2026"; the three stages; the investor index; and the command line. The tests found a real bug before release (.env secret files were not being flagged), which is fixed. Two deliberate breaks were each caught, and it was run from an unzipped copy of the download.
No. It is a practical checklist, not legal or tax advice. What investors require varies; ask your lawyer. It is not affiliated with any investor, law firm, data-room provider or cloud-storage company.
