Straiker announced that it has raised $64 million in Series A funding to secure enterprise AI agents. The round was led by Marathon Management Partners, Citi Ventures, Illuminate Financial, and Workday Ventures, with continued support from Bain Capital Ventures and Lightspeed. The financing brings Straiker’s total funding to $85 million. Gokul Rajaram, founding partner of Marathon, is joining Straiker’s board of directors.
Straiker is an agentic security company focused on helping enterprises discover, test, and protect AI agents as they become more widely deployed across business workflows.
The company said AI agents are becoming the fastest-growing workforce in the enterprise, automating a growing range of work across productivity tasks, back-office operations, and mission-critical customer workflows.
IDC expects more than one billion AI agents to be deployed across enterprises by 2029, representing a 40x increase from 2025.
Straiker said AI agents create a new class of risk because they can reason dynamically and act independently across systems on behalf of users. This autonomy creates security challenges that traditional deterministic controls were not designed to govern.
The company cited adversarial testing by STAR Labs, its dedicated AI threat research arm, which found that 36% of successful attacks on coding agents resulted in remote code execution, while 91% of attacks on productivity agents led to silent data exfiltration without malware or stolen credentials.
Straiker’s platform is built around three integrated capabilities: discovery of AI agents across enterprise environments, pre-deployment adversarial testing to surface vulnerabilities, and runtime protection that monitors activity and stops threats as they happen.
The company said its shared intelligence layer allows threats detected in production to strengthen pre-deployment testing, while vulnerabilities discovered in testing harden runtime protections.
Straiker’s founding team includes CEO Ankur Shah, who previously scaled Palo Alto Networks’ Prisma Cloud business as senior vice president and general manager, and CTO Sreenath Kurupati, who led AI and security research at Akamai after its acquisition of Cyberfend, a fraud detection company he founded.
Since launching in 2025, Straiker has worked with frontier AI labs and Fortune 500 enterprises to help them securely deploy internally built and third-party agents.
The company said it has grown run-rate revenue by more than 15x in less than a year.
Straiker plans to use the funding to invest in product development, STAR Labs threat research, and global expansion.
KEY QUOTES:
“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.”
Sreenath Kurupati, Co-Founder and CTO of Straiker
“AI agents are getting the keys to real systems and real data, which makes securing them one of the defining challenges of this era. I’m glad to work with innovative teams like Straiker that are focused on getting it right.”
Brad Jones, Chief Information Security Officer
“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.”
Ankur Shah, Co-Founder and CEO of Straiker
“Given their scope and autonomy, AI agents need to be treated like first-class citizens. Enterprises need a purpose-built solution given the magnitude of the problem. Straiker will be one of the few companies that define how agents are secured.”
