Cymphony Emerges From Stealth With $30M to Monitor AI Agent Access

Cymphony Inc., an enterprise security company, unveiled itself today following a $30 million funding round aimed at providing visibility into what AI agents and workers can reach across corporate infrastructure. The startup, founded two years ago, now carries a valuation exceeding $100 million, according to TechCrunch.

The company's core offering relies on what it terms a workforce security graph—essentially a unified view mapping identities, access rights, confidential information and user actions that allows security personnel to determine which employees, AI systems and service accounts have interacted with specific resources. The solution requires no endpoint installation and can be operational within a single day, Cymphony stated.

Chief Executive Shy Dekel highlighted a case involving an early client that integrated ChatGPT with SharePoint while maintaining existing security measures. According to Dekel, "an incredibly sensitive litigation process" became accessible to interns at the organization through document queries. Dekel attributed the situation to an unintentional oversight within the legal team.

Platform capabilities

Cymphony's offering encompasses four distinct functional areas. The first monitors which AI applications employees utilize and what information they input into them. The second identifies business information that has leaked or been inappropriately distributed. The third focuses on identity management, addressing concerns such as unused admin credentials and accounts lacking multifactor authentication protection. A fourth component, the threat center, detects suspicious insider activities including mass file transfers. A conversational tool named Maestro handles investigation and response workflows using natural language rather than formal query commands.

Customer base and early traction

The startup counts Syngenta, KKR & Co. Inc., Cass Information Systems Inc. and Athennian among its initial clients. Sequoia Capital has also deployed the platform internally. Within its opening year of commercial operations, Cymphony surpassed seven figures in annual recurring revenue, TechCrunch reported.

Leadership and team

Dekel previously spent nearly six years with Israel's Unit 8200, where he led the cyber operations division. Chief Technology Officer Edi Gotlieb brings experience from engineering positions at Apple Inc. and Israel's Ministry of Defense. Chief Product Officer Idan Berkovits previously oversaw research initiatives within the Office of the Prime Minister. All three co-founders attended Talpiot, Israel's military technology academy. The organization currently maintains approximately 30 employees split between New York and Tel Aviv.

Funding details

The $30 million comprises a $25 million Series A round co-led by Sequoia Capital and SMBC Fin Atlas Beyond Fund. Sumitomo Mitsui Banking Corp. and Fin Capital established the $300 million fund in July 2025 to invest in emerging U.S. fintech companies. Sequoia had previously backed the company through an undisclosed seed investment.

Sequoia partner Bogomil Balkansky characterized the AI agent workforce as representing the next major transformation, noting that entities providing "visibility and control" over this emerging workforce possess the potential to establish a dominant foundational platform. Logan Allin, managing partner at SMBC Fin Atlas Beyond Fund, framed the opportunity around insider threat mitigation, emphasizing that contemporary risks extend beyond human actors and that enterprises require comprehensive end-to-end solutions.
