GoKawiilBrowser security startup Island raises $400M at $6.4B valuation
Dallas-based Island announced a $400 million funding round led by Evolution Equity Partners, valuing the company at $6.4 billion. CEO Mike Fey said the capital will fund research, expansion into Europe, Asia and the Middle East, and workforce growth from 1,000 to 1,500 employees by mid-2026. Island's customers include Pfizer, Chipotle and American Airlines, and it ranked No. 28 on this year's CNBC Disruptor 50 list.
GoKawiil's interpretation of the reporting above, not reported fact.
The raise suggests investors see rising demand for enterprise security tools as AI agents introduce new attack surfaces, a concern heightened by incidents like OpenAI's agent-driven attack on Hugging Face. Fey's comment that 'every old control is breaking' frames the funding as a bet that traditional security models are becoming obsolete amid AI-driven threats. The timing also coincides with ongoing debate in Washington over AI regulation, which could shape how quickly such security spending accelerates.
