Cymphony has emerged with $30 million in funding for a security platform that maps the systems and sensitive data available to employees, AI agents and other non-human identities. The total includes a $25 million Series A co-led by Sequoia Capital and SMBC Fin Atlas Beyond Fund, valuing the company above $100 million after the investment.
Its workforce graph combines identity, access and activity signals so security teams can investigate exposure and correct permissions. Cymphony says it found about 85,000 files available to AI tools at one US public company, then helped close the access without finding evidence that those files had been reached through the systems. In another case, an outside collaborator’s unsanctioned Claude installation reportedly scanned thousands of sensitive files using that person’s existing privileges.
The two-year-old startup says it has a double-digit number of enterprise customers and seven-figure annual recurring revenue. Those figures and incident results come from Cymphony, not an independent audit. It must also compete with Microsoft, Okta, CyberArk, Wiz and other established vendors adding agent controls. For now, customers largely use it as an extra governance layer rather than replacing core identity systems.
