Cap-table de-identification is the removal of holder PII from an ownership table. It supports anonymous sharing under GDPR Recital 26. anonym.plus works on your device and keeps the share counts, classes, and percentages that bidders need.
When this applies
A capitalization table lists every owner, their shares, and their contact data. Bidders need the split, not the names. Strip those details first.
How anonym.plus handles it
- Open the grid in anonym.plus on your device.
- It finds owner names, emails, and tax or ID numbers.
- Share counts, classes, and percentages stay in place.
- Swap each party for a steady label across joined rows.
- Save the clean grid on your device.
What you need to provide
- The grid (XLSX, CSV, PDF, or export).
- A column map for known owner fields.
- Replace with a steady label map to keep row links.

Limitations & cautions
A small owner set can re-identify by share size alone, even after names go. A 40% block points to one fund. Weigh whether the split itself is a clue before you treat the grid as anonymous.
Frequently asked questions
Are the share counts removed?
No. The counts, classes, and percentages stay. Only names, IDs, and contacts change, so the math is intact.
Can rows stay linkable after the swap?
Yes. A steady label map swaps each owner the same way, so rows for one party still join while no real name is left.
Does it handle XLSX as well as PDF?
Yes. Spreadsheet exports and PDF tables both work on your device.
