Episode notes
AI Funding Now Rewards Traction
- AI funding shifted from hype to requiring real traction and problem-solving instead of pure model-building.
- Pre-seed and seed rounds are brutal; teams must show customers or measurable signals before investors write checks.
VCs Back AI Applications Over Generic Models
- VCs are placing smaller option-like bets at the AI application layer rather than on generic foundational models.
- Investors prefer verticalized, specialized SaaS applications where they can foresee defensible wins.
Hardware's Value Is Vertical Integration
- Hardware regained attention where tight hardware-software integration creates real defensibility and domain advantage.
- Defense and medical devices are attractive because firmware-close-to-metal advantages are hard to replicate.
