## Summary

Sierra is acquiring Anon, a startup that built infrastructure for AI agents to sign in to websites and complete tasks without APIs. Anon raised more than $13M and says it completed hundreds of thousands of complex tasks in production, with its team and technology joining Sierra. Sierra says the deal will help its Horizon agents carry out multi-step goals, such as loan origination and prior authorization, that require working through services lacking APIs.
