What happened
- On September 24, Island announced a $400 million Series F round that brings its valuation to $6.4 billion, according to the press release published on its corporate site.
- The round was led by Evolution Equity Partners, with participation from Sequoia Capital, Coatue, Insight Partners, Cyberstarts, Prysm Capital and J.P. Morgan Growth Equity Partners, among others.
- The company reports 1,000 employees and says it has doubled its annual recurring revenue every fiscal year since its launch in 2022.
- Its positioning changed names: Island no longer describes itself as an enterprise browser, but as an agentic control plane, with identity, permissions, spending limits and audit logs for people and agents alike.
Why it matters
- The money is following a concrete assumption: that companies will have agents carrying out actions before they have a way to supervise them. That gap is the product.
- For marketing and operations teams in Chile that have already connected assistants to their email, CRM or billing, the operational question stops being which model to use and becomes who signs off on each action. Without a per-action log, there’s no way to answer to an audit or to Law 21.719.
- There’s an uncomfortable reading of the amount: a $6.4 billion valuation is the price the market puts on distrust of the tools the same market is installing.
The number
$6.4 billion. More than double the valuation the company had in 2024.
Context
Island’s sales pitch changed its axis without the core product changing. Before, it sold browser control against unmanaged employees and devices; now it sells control against software that acts on its own. The shift comes after a year in which it was documented how agent autonomy becomes a risk surface and how the combination of private data, external content and the ability to send information opens a leak path that’s hard to close.
What’s next
- No date announced for new products stemming from the round.
- The company says the funds will go to growth and innovation, with no breakdown or public revenue targets.
- There’s also no announcement of direct operations in Latin America.
Bottom line
The category now called agent control has the same origin as almost every security category: first the capability is deployed, then it’s discovered that nobody was watching it. What’s new is how short the gap between the two has become.
