Carta

Carta is the dominant platform for cap table management, equity administration, and private company valuations. Over 40,000 companies and 2 million+ stakeholders use Carta to manage equity grants, 409A valuations, and investor reporting. If you hold equity in a private company, there is a good chance it is administered through Carta.

For investors, Carta provides CartaX (now Carta Private Markets), a secondary market for buying and selling shares of private companies. Carta also offers fund administration services for venture capital firms, handling everything from capital calls to K-1 generation. The data Carta sits on — equity ownership across thousands of private companies — gives it a unique position in the startup ecosystem.

Carta's 409A valuation service is used by startups to set fair market values for stock options, making it relevant to anyone who holds startup equity. The platform's reporting tools give investors clear visibility into their private company holdings across multiple investments.
