GoKawiilSequoia leads $25M Series A in Cymphony to secure AI agent access
Cymphony, a New York- and Tel Aviv-based startup, raised a $25 million Series A co-led by Sequoia Capital and SMBC Fin Atlas Beyond Fund, pushing its valuation above $100 million after a previously undisclosed Sequoia seed round. The company builds a 'workforce graph' that gives security teams visibility into which employees, AI agents, and other non-human identities can access sensitive systems and data.
GoKawiil's interpretation of the reporting above, not reported fact.
As AI agents increasingly operate with the same data access as human employees but without equivalent identity controls, enterprises face blind spots that traditional security tools weren't built to catch. Cymphony's early findings, including tens of thousands of exposed files at one client, show these risks are already materializing inside large organizations, not just theoretical concerns.
- Cymphony raised $30M total, including a $25M Series A led by Sequoia and SMBC Fin Atlas Beyond Fund.
- The startup's 'workforce graph' unifies identity, data, and activity signals to track human and AI agent access.
- Real-world audits found risks like 85,000 exposed files and unsanctioned AI tool installations at client companies.
