Sierra acquires Anon to give its AI agents browser access

See how this story connects

Sierra announced on 5 November 2026 that it has acquired Anon, adding the startup’s team and browser-agent technology so its AI agents can sign in to websites, navigate portals and complete work in services without APIs. Anon had raised more than $13 million and shipped a product used by hundreds of customers, and its visual builder records browser workflows for agents to replay. Sierra introduced its Horizon platform for long-running agent goals on 16 July 2026.

Why it matters

Horizon customers pay for business outcomes delivered, with Sierra managing token spend, and Sierra expects Anon to carry its agents through website sign-ins and portal steps.
