Root Causes
Key Lessons Learned
1. Don't Overpromise on Deep Tech Timelines
Quanergy promised $100 solid-state LiDAR units but couldn't deliver at any price point.
2. Hype Without Product Is Dangerous
CES demos and media coverage inflated valuation far beyond what the technology could deliver.
3. Hardware Markets Punish Late Entrants
By the time Quanergy could theoretically ship, competitors had locked up major automotive contracts.
