Etched's $21B Valuation: Specialized Chips Win Over General Compute

Etched doubled its valuation from $10.3B to $21B in one month. Series C: $700M led by Jane Street, Kleiner Perkins, Sequoia, a16z.

Key metrics:
- $1B+ customer contracts already signed
- Jane Street deployed first chip rack last month
- Specialized inference chip optimized for tokens-per-dollar
- 400+ employees, working product

How they won:
1. Identified inference as the real bottleneck (not training)
2. Built defensible tech competitors can't easily copy
3. Secured strategic customer who became lead investor
4. Proved $1B+ demand before Series C

Founder lesson: Don't build for everyone. Build for one buyer's hard problem with technology they can't replicate. Etched didn't try to beat Nvidia at everything—they won on inference efficiency.
