Straiker, an agentic security company that protects AI-driven workforces in enterprise environments, has raised $64m in a Series A funding round, bringing its total capital raised to $85m.
The round was led by Marathon Management Partners, Citi Ventures, Illuminate Financial, and Workday Ventures, with follow-on participation from existing backers Bain Capital Ventures and Lightspeed. As part of the deal, Gokul Rajaram, founding partner at Marathon, will take a seat on Straiker’s board of directors.
AI agents are now the fastest-growing category of workforce in enterprise technology. IDC projects more than one billion agents will be deployed across enterprises by 2029, representing a 40-fold increase from 2025 levels. Unlike conventional software, agents operate independently across systems, reasoning dynamically on behalf of users, a capability that introduces an entirely new category of security risk.
In adversarial testing conducted by STAR Labs, Straiker’s dedicated AI threat research arm, 36% of successful attacks on coding agents resulted in remote code execution, while 91% of attacks on productivity agents produced silent data exfiltration with no malware or stolen credentials involved.
Straiker’s platform addresses these risks through three integrated capabilities: discovery of AI agents across enterprise environments, pre-deployment adversarial testing to identify vulnerabilities before agents go live, and runtime protection that monitors agent activity and stops threats in real time.
A shared intelligence layer connects these functions, so threats identified in production sharpen pre-deployment tests, while vulnerabilities uncovered during testing reinforce runtime defences. The company’s relationships with frontier AI labs give it early access to emerging attack techniques, allowing its detection capabilities to evolve alongside AI systems.
Straiker was founded by CEO Ankur Shah, who previously led Palo Alto Networks’ Prisma Cloud business as SVP and GM, and CTO Sreenath Kurupati, who headed AI and security research at Akamai following its acquisition of Cyberfend, the fraud detection company he founded. Since its 2025 launch, the company has built a client base spanning frontier AI labs and Fortune 500 enterprises. Run-rate revenue has grown more than 15 times over in under a year, reflecting rising demand for security infrastructure built specifically for autonomous systems.
Straiker co-founder and CTO Sreenath Kurupati said, “Our uniqueness comes from pairing the industry’s most comprehensive agentic exploit dataset with an AI-native security engine purpose-built for autonomous threats. That foundation allows us to secure the next generation of AI-powered enterprises.”
Straiker co-founder and CEO Ankur Shah said, “Demand is outpacing anything we forecast. This round goes straight into product, our STAR Labs threat research, and the global expansion our enterprise customers are pulling us toward.”
