Sierra acquires Anon to strengthen browser actions for customer agents

Anon announced it is joining Sierra, bringing browser-use, authentication and credential-handling expertise to agents that need to navigate sites without APIs. The post says Anon had raised more than $13 million historically; that figure is not new financing for Sierra or a disclosed acquisition price. It describes intended integration into Sierra agents, not proof that all Anon features are already live in Sierra.
