Enterprise AI-Agent Security Startup Cymphony Exits Stealth With $30M, Sequoia and SMBC Lead $25M Series A

Cymphony emerged from stealth with $30M in total funding — including a $25M Series A co-led by Sequoia Capital and SMBC Fin Atlas Beyond Fund — at a $100M+ post-money valuation. Its 'workforce graph' unifies human, AI-agent and non-human identities so security teams can trace access and automate remediation, including permissions correction. CEO Shy Dekel says the platform surfaced roughly 85,000 files inadvertently exposed to AI tools at one major US public company.
