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 note that while AI agents are increasingly automating software engineering work, similar tools do not yet exist for engineers working on physical systems. They observe that engineering teams are frequently slowed by administrative workflows rather than engineering itself, and they are building AI agents to handle that routine work.
- What is your long-term vision? If you truly succeed, what will be different about the world?
- The founders envision human engineers working alongside AI engineers, with humans focusing on design and decision-making while routine constraints are removed.
