In less than a year, enterprise browser startup Island has significantly boosted its valuation. Securing a hefty $250 million Series E round. The Dallas-based company is now valued at $4.85 billion. Marking a major leap from its previous $2.9 billion valuation just 11 months ago.
Leading this latest round is Coatue, with continued support from heavyweights like Insight Partners, Sequoia Capital, and Canapi Ventures. This new injection of capital brings Island’s total funding to $730 million. An impressive war chest for a company that launched just under five years ago.
What sets Island apart in the crowded cybersecurity and enterprise software space is its purpose-built browser. Unlike mainstream browsers, Island’s solution is tailored for enterprise use, offering deeper security layers and tighter control for IT teams. Their browser, built on Chromium, mimics the look and feel of standard browsers but is packed with enterprise-grade protections.
The platform delivers robust features like universal application access control, device visibility and management, and seamless automation. Key elements for businesses juggling remote workforces, strict compliance, and rising cybersecurity threats.
Island’s momentum isn’t just investor hype. The company has grown its customer base to 450 organizations, with names like Mattress Firm, Swiss Life, and Fiverr already onboard. This strong adoption validates Island’s core belief: enterprises want seamless user experiences without sacrificing security.
Mike Fey, a seasoned U.S. security executive, co-founded Island with Dan Amiga, a technical visionary from Israel. Their combined experience and clear vision drew early attention from top-tier VCs. Sequoia partner Doug Leone previously highlighted Island’s compelling mix of usability and security, noting that the founders’ mission to secure enterprise environments without disrupting workflows was a standout.
This latest round cements Island’s place in the growing market of secure enterprise tech—an area increasingly under the spotlight as cyber threats become more sophisticated and workplace tools continue to shift online. With a $4.85 billion valuation and momentum from some of the biggest names in venture capital, Island is poised to expand its reach across industries hungry for secure, user-friendly browser solutions.
