Exaforce Raises $125 Million Series B at $725 Million Valuation to Deploy AI Against Real-Time Cyberattacks

Exaforce, a three-year-old AI cybersecurity startup, has closed a $125 million Series B funding round at a valuation of $725 million, as enterprises facing a surge in AI-powered threats seek automated defenses capable of responding in real time.

The round drew participation from HarbourVest, Peak XV, Mayfield, Khosla Ventures, and Seligman Ventures, and follows a $75 million Series A raised just one year prior. Total funding for the company now stands at $200 million.

At its core, Exaforce builds what it calls an AI-enabled security operations center, or SOC, using autonomous agents the company refers to as "Exabots." The platform is designed to automate the labor-intensive work of security analysts — sorting through alerts, identifying genuine threats, and taking action — with the company claiming its system can cut manual, time-consuming tasks by as much as 90%.

Co-founder and CEO Ankur Singla described the company's mission to reporters in straightforward terms. "It's a very simple mandate, but it's very complex to execute," he said.

A central challenge the platform addresses is alert fatigue. Security teams routinely face hundreds of notifications per shift, the overwhelming majority of which are false positives. "How do you know what is a real, high-priority alert?" said Umesh Padval, a managing partner at Seligman Ventures, characterizing the work as searching for a needle in a haystack.

Exaforce brought its product to market in the fourth quarter of last year, after two years of closed testing with design partners. The startup currently counts 20 customers, including software platform Replit and oncology diagnostics company Guardant Health. Singla told reporters the company expects to reach between 40 and 50 customers by year's end.

The company recently introduced a feature called "vibe hunting," which allows security analysts to query the platform using natural language prompts built around informal hypotheses. Singla offered an example: "With vibe hunting, you can ask a very simple hypothesis like, 'Did we get any new attacks from Iran?'"

High-profile breaches have accelerated customer acquisition, Singla said, noting that prospective clients no longer question the need for automated threat detection. "How do I operationalize it?" is now the question he hears most often.

Exaforce operates in a competitive and rapidly expanding market. Rivals include AI security startups 7AI, Dropzone AI, and Prophet Security, alongside established cybersecurity firms Palo Alto Networks and CrowdStrike.

The funding round underscores both the substantial capital requirements for building AI-driven security infrastructure and the scale of the opportunity investors see in the sector — reinforcing a broader pattern of venture money flowing toward companies positioned at the intersection of artificial intelligence and enterprise defense as threat actors deploy the same tools to accelerate attacks.
