Alumni Q&A
- What is the core problem you are solving? Why is this a big problem? What made you decide to work on it?
- The founders argue that most modern work now happens inside the browser, but current AI agents operate externally and require numerous integrations, repeated context, and step-by-step approvals. They are building a browser that acts on the user's behalf without integrations.
Summarized from the founders' answers on their Y Combinator profile.
