Company intelligence
As of September 24, 2026, Island was last valued at $6.4B (September 2026 Series F) and has raised at least $400M in equity across 1 sourced funding round.

Reuters reported that Island lists PayPal and Amazon, among others, as customers on its website.[3] Island says it has doubled annual recurring revenue every fiscal year since its 2022 launch but has not disclosed a figure; Calcalist's CTech reported ARR of about $200 million.[2]
Island, the Dallas maker of the Enterprise Browser, raised a $400 million Series F at a $6.4 billion valuation in September 2026.
Island is a Dallas-based company that makes the Enterprise Browser, a work browser with company security, access and productivity controls built into it. The company's position is that most knowledge work now happens in a browser, so the browser is the place to put security controls. From that starting point it added data loss prevention and network security, and it now also offers an extension for consumer browsers.[1],[2]
Since its Series F in September 2026 the company describes itself as an agentic control plane for enterprises rather than only a browser vendor. In the company's framing, one policy engine and one audit trail cover browsers, devices, applications, networks and data, for both employees and AI agents. Its Enterprise AI product adds identity controls, guardrails, human approvals and cost limits for agents and works with whichever AI models a customer chooses. CTO Dan Amiga's argument is that agents do not operate in a single layer of the technology stack, so they cannot be governed from one.[1],[2]
Island is not alone in this market. The Next Web notes that Palo Alto Networks also sells an enterprise browser after buying the Israeli startup Talon in 2023, Cloudflare has launched a browser for AI agents, and Neo came out of stealth in July 2026 with $100 million to build a control layer for agents.[1]
Island was founded in 2020 by Dan Amiga, now chief technology officer, and Mike Fey, the chief executive, who was previously president of Symantec and CTO of McAfee, according to Globes. The product launched in 2022. Island has about 1,000 employees, including roughly 400 at its development center in Tel Aviv, and Globes reports the company doubled its Israel workforce over the past 18 months. Calcalist's CTech, cited by The Next Web, reported Island had more than 500 staff a year before the Series F.[3],[1]
The company did not say whether the figure is pre- or post-money. Existing investors Prysm Capital, Sequoia Capital, Coatue Management, Cyberstarts, Insight Partners, J.P. Morgan Growth Equity Partners, Alta Park Capital, Georgian, G Squared and Squarepoint participated, and Dmitri Alperovitch, the CrowdStrike co-founder and former CTO, made another personal investment. Island said the money will fund its next phase of growth as enterprises scale AI agents.[3],[1],[2]
Reuters reported that Island lists PayPal, Amazon and Pfizer, among others, as customers on its website. Island has not published customer counts or revenue, so the customer base is known only from these named logos.[4]
