Carta is the system of record for who owns what in private companies and funds. Founders use it to issue options and model funding rounds, employees use it to see and exercise their equity, and VC, PE, and private credit managers use it to run fund accounting and LP reporting. That position between companies and investors is what lets Carta sell valuations, fund administration, and legal services. The company is headquartered in San Francisco, California.
Carta sells annual software subscriptions plus service fees on both sides of the private market. Companies pay for cap table management, equity plan administration, and 409A valuations, with prices rising as stakeholder counts and funding stages grow. Investment firms pay for Fund ERP products: fund administration (software plus dedicated fund accountants), fund tax and K-1s, portfolio valuations, CRM, forecasting, and loan operations for private credit. Since May 2026, Carta Law adds outcome-based legal and compliance work such as NDAs, KYC, investor onboarding, and LP transfers. Sacra estimates that in 2023 cap tables and 409A valuations made up about 67% of ARR, fund administration about 27%, and private equity products about 5%. Carta shut its secondary trading business in January 2024, so brokerage is no longer part of the model.
