About CartaX
CartaX is a marketplace operated by Carta — the company best known for cap-table management software used by a large share of venture-backed startups — built to let those same companies run structured liquidity events (like tender offers) directly on top of their existing cap-table data.
Because CartaX sits on the same infrastructure a company already uses to track who owns what, it can reduce some of the administrative back-and-forth that slows down a bespoke secondary transfer.
How it works
A company that already uses Carta for its cap table can opt to run a structured liquidity event through CartaX, inviting eligible shareholders to participate under company-set terms — similar in structure to a tender offer administered elsewhere.
As with other company-run liquidity infrastructure, access is initiated by the company, not something an outside investor can browse into independently.
Every platform in this directory requires accredited investor status, and every listing carries the same underlying risks: limited information rights, no board access, and illiquidity that can last years. None of this is investment advice — verify current fees, minimums, and available listings directly on the platform, and treat any specific opportunity with the same diligence you'd apply to a primary investment.
