Documented cause
Circulor raised $33M to build blockchain-based supply chain traceability for battery materials and ethical sourcing, with clients including Volvo, Rolls-Royce, and Umicore. CEO Douglas Johnson-Poensgen built partnerships across 25 countries. By 2024, the company shut down after the EU Battery Regulation timelines slipped and large automotive OEMs chose in-house traceability systems over third-party platforms, collapsing the anticipated compliance-driven revenue model.
Lesson
“Regulatory compliance startups must hedge against timeline slippage — don't build the entire model around a single law's deadline.”
