Lilium
German electric jet startup raised €900M to build air taxis. Filed for insolvency before completing a single commercial flight. Then came back from the dead.
Evaluating only Lilium’s profile at its peak — without knowing the outcome — the model ranked Unit economics as the #1 likely cause. That’s exactly how it died.

Documented cause
Lilium raised €900M from Tencent, Atomico, and LGT to develop an electric VTOL jet — a fundamentally different approach to air taxis using electric jet engines rather than rotors. The SPAC IPO at $3.3B in 2021 preceded repeated delays in battery technology and certification. In November 2023, Lilium filed for insolvency after Germany's government refused a requested €50M bridge loan. A US-based investment consortium revived the brand in early 2024, but the original company and most employees were lost.
Lesson
“Aviation hardware startups should structure funding in tranches tied to FAA/EASA certification milestones, not calendar dates. Certification delays are the rule, not the exception.”
