Your questions answered
What is cap table management?
Cap table management is the process of tracking who owns shares in your company and how ownership changes over time. A modern cap table records founders, investors, employees, option holders and every equity event, helping you maintain accurate ownership records, model dilution and prepare for future fundraising.
What should a UK cap table include?
A UK cap table should include all shareholders, share classes, issued shares, option grants, convertible instruments, ownership percentages, historical funding rounds and fully diluted ownership. Keeping this information accurate helps ensure investor confidence and supports Companies House and HMRC compliance.
How do you manage a cap table during funding rounds?
Each funding round should update your cap table to reflect new share issues, dilution and ownership changes. A dedicated cap table platform automates calculations, tracks historical events, updates ownership percentages and provides a clear audit trail before shares are issued.
What's the difference between a cap table and the register of members?
A cap table is an internal financial record used to understand ownership, dilution and fundraising scenarios. The register of members is the company’s official statutory register showing the legal owners of issued shares. Both should remain consistent, but they serve different purposes.
Can I import my cap table from Excel or Carta?
Yes. Undo Capital allows you to import your existing cap table from spreadsheets or other platforms, making it easy to migrate historical ownership records without rebuilding everything manually. Once imported, you can continue managing funding rounds, option pools and shareholder changes in one place.
