Their product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior. The objective is to help users complete tasks daily enjoyable with over ~90%* reduced time.

The best products today in the world were built by small, world class teams. This is a high talent density and hands-on team. They make decisions collectively, move at rapid speed, striking a balance between shipping high quality work and learning. Joining the team requires the ability to bring structure, exercise judgment, and execute independently. The goal is to put in hands of users a truly magical product.
