Comparison
Perseids vs Carta
Perseids and Carta both address private-company ownership. This page states, in verifiable terms, what Perseids provides. Carta's current capabilities, plan contents and pricing change over time and are not restated here: the Carta column asks you to confirm each item with the provider, which is also the only defensible way to compare two products at a point in time.

Where the approaches differ
Perseids treats the ownership record as infrastructure that other workflows run on: modelling, diligence, secondary and strategic deals read from the same ledger rather than from exports of it. Whether that matters depends on how many ownership-adjacent workflows you actually run. A company that only needs a register and annual filings has different requirements from one running a raise, a secondary and an employee exercise window in the same quarter.
How to compare the two properly
- 1Write down the workflows you run in a year, not the features you might use.
- 2Ask each provider, in writing, which of those are included in the plan you would buy.
- 3Confirm the billing currency, the contract term and what happens on downgrade.
- 4Confirm the export format, so you can leave either product with your data intact.
- 5Ask how ownership figures are calculated and whether they are reproducible.
This comparison describes different approaches, not a ranking. Product capabilities change; verify current details with each vendor before making a decision.
Frequently asked questions
- Is Perseids a Carta alternative?
- Perseids is cap table and equity management software with fundraising modelling, investor data rooms, investor portfolio tools and secondary workflows, so it covers overlapping ground. Whether it is the right alternative depends on which workflows you need; confirm Carta's current scope with Carta.
- Can I move an existing cap table to Perseids?
- Yes. Perseids imports cap tables from spreadsheets and from exports produced by other equity platforms, and reconciles the imported position before it becomes authoritative.
- What does Perseids cost compared with Carta?
- Perseids publishes its plan prices on the pricing page, in GBP, USD and EUR. Carta's pricing should be confirmed with Carta, as plan contents and regional pricing change.
