Surf AI, an agentic operations platform built for modern security teams, has launched with $57m in funding aimed at accelerating the development of its AI-native security execution capabilities.
The raise was led by Accel, with participation from existing backers Cyberstarts and Boldstart Ventures. The proceeds will be directed towards product development, team expansion, and scaling to support broader enterprise adoption.
Founded in 2024 by a team of veterans from the Israeli cybersecurity ecosystem — including Yair Grindlinger, Elad Horn, Roie Cohen Duwek, Avner Gideoni, and Brenton Gumucio — Surf AI was built in response to what its founders see as a fundamental mismatch between the complexity of today’s threat landscape and the operational models security teams are still relying on.
Risk is now scattered across identities, cloud infrastructure, data, and business systems, while ownership and execution remain fragmented across tools and teams. As AI accelerates both the pace and sophistication of attacks, organisations are under mounting pressure to manage risk continuously — using frameworks that were never designed for that reality.
The company’s platform attempts to address this through a single agentic layer that connects business context and data spread across an organisation’s systems. It reads signals from identity, cloud, security, data, HR, and IT tools to construct a living context graph linking assets, owners, permissions, and dependencies. From there, it prioritises risk according to real business impact and coordinates remediation through goal-oriented workflows, with specialised AI agents driving execution under human oversight. Critically, context is preserved throughout, allowing teams to act without repeated handoffs or rework.
The new capital will fund continued investment in product development and headcount, as the company looks to expand its engineering and security leadership teams across the US and Israel, while scaling its enterprise client base — which already includes Fortune 500 companies.
In early client deployments, Surf AI has helped organisations recover nearly $1m in excess SaaS licence spend, disable thousands of dormant and orphaned accounts, remediate significant certificate risks, and automate identity enforcement workflows at enterprise scale.
Surf AI CEO and co-founder Yair Grindlinger said, “We built Surf AI to operationalize the entire security program with AI. Proactive security hygiene is exactly what we’re encouraging, and our platform is designed to continuously find and close the exposure gaps that teams have always known about but didn’t have the time or resources to address. Surf AI connects the context, drives the remediation, and keeps your team in control at every step.”
Accel partner Philippe Botteri said, “AI is dramatically increasing the speed and sophistication of attackers, and security teams need fundamentally new operating models to keep up. The Surf AI team is building an agentic platform to significantly enhance the productivity of security teams and make their organisation resilient to this new threat landscape.”
Cyberstarts founder Gili Raanan said, “We backed the Surf AI team at seed as the founders have already successfully scaled a cybersecurity business to hundreds of millions in revenue. With that experience at Surf AI, they are building an agentic security platform designed for a world where defenders need AI systems that can reason, adapt, and operate at an enterprise scale.”
Boldstart Ventures founder and general partner Ed Sim said, “Security leaders are under pressure to reduce risk continuously with fewer resources. Too many enterprises are spending heavily on tools that only address problems on the surface. We backed Surf AI from inception because it flips that model with an agentic execution layer for security, turning fragmented context into coordinated action that helps CISOs reduce risk while saving time, effort, and costs.”
Cushman & Wakefield chief information security officer Erik Hart said, “Surf AI combines advanced analytics with agentic intelligence to convert business context into action. It’s helped us operate continuously at scale, lower risk, optimize costs, and improve our security posture, producing measurable ROI in weeks and enabling teams to scale their impact with speed and confidence.”
