Sharing some trends I'm excited by from the W24 batch of YC companies:

- Foundational models for hard problems (physics, materials, neuroscience)
- The return of hardware (batteries, drones, robots)
- AI infra and tooling (RAG, databases, memory, data labeling, testing)

Additional emergent or strengthening trends:

- AI for content (games, video, music)
- AI for understanding code (context, documentation, search)
- AI for security (alerts, bugs, observability)
- Operating system for X (factories, construction, satellites)
