Island Raises $400M Series F, Valued at $6.4 Billion

In a significant validation of the evolving enterprise technology stack, Island has successfully closed a $400 million Series F funding round, propelling its valuation to an impressive $6.4 billion. This latest infusion of capital, led by Evolution Equity Partners, underscores the market's strong conviction in Island's vision for an agentic control plane designed to manage both human and artificial intelligence workforce interactions. The substantial funding more than doubles the company's valuation since 2024, signaling robust growth and increasing demand for its innovative solutions.

The capital injection is earmarked to accelerate Island's product development and expand its market reach, particularly as organizations grapple with the complexities of scaling AI agents and modernizing their operational frameworks. The company's platform provides a critical layer of visibility, governance, and auditing, essential for enterprises navigating the complexities of the AI era. This strategic funding positions Island to further solidify its category leadership in securing and managing the future of work.

Richard Seewald, Founder and Managing Partner at Evolution Equity Partners, highlighted the timely relevance of Island's offering. "Enterprises are fundamentally re-architecting how work is accomplished. Island is uniquely positioned to address this moment, offering unparalleled insight and governance over the actions of both people and AI agents as they interact with applications and data across the enterprise," Seewald stated. He further emphasized Island's proven ability to establish new market categories, displace established technologies, and drive significant business transformation by extending its control from the browser to the network and endpoint.

The Series F round saw robust participation from a distinguished group of existing and new investors. Alongside the lead investor, Evolution Equity Partners, the round included significant contributions from Prysm Capital, Sequoia Capital, Coatue Management, Cyberstarts, Insight Partners, J.P. Morgan Growth Equity Partners, Alta Park Capital, Georgian, G Squared, and Squarepoint. Additionally, cybersecurity luminary Dmitri Alperovitch made a personal investment, further underscoring confidence in the company's trajectory.

Island's impressive financial performance is further evidenced by its consistent growth, having doubled its annual recurring revenue (ARR) each fiscal year since its inception in 2022. The company, now employing 1,000 individuals, attributes this sustained expansion to the escalating enterprise need for secure AI adoption, streamlined network architectures, simplified security infrastructure, and frictionless data protection. This growth trajectory aligns with broader market trends indicating a significant shift towards integrated security and productivity solutions that support advanced digital workflows.

The company's innovative approach, which began with the pioneering Enterprise Browser, has expanded to encompass data protection, DLP, and a next-generation SASE architecture. This comprehensive strategy provides CIOs and CISOs with a unified framework for security, productivity, and governance across all human and agentic work activities. As Mike Fey, CEO and Co-founder of Island, noted, "We've entered a new era where humans and AI agents collaborate. Island provides the essential context, access controls, guardrails, and accountability mechanisms necessary for this paradigm." This investment will empower Island to further enhance its capabilities and support customers in safely scaling their AI initiatives.
