Lilium vs Spotahome
Lilium failed in 2023 due to Unit Economics. Spotahome failed in 2020 due to Bad Timing. Different causes, different sectors, different eras — but the same simulation outcome.

// WHY EACH FAILED
🔥 Lilium
Unit Economics
Lilium developed an electric vertical takeoff and landing (eVTOL) jet with 7 seats and 300km range. Post-SPAC listing at €3.4B, the company faced an engineering reality: its battery density requirements exceeded current lithium-ion technology. Each test aircraft consumed 3× the projected energy. The FAA and EASA certification process required 50,000+ test hours that Lilium hadn't budgeted for. Pre-revenue, burning €100M/year, unable to raise a further €400M needed for certification, Lilium filed for insolvency in October 2023. No commercial flight ever operated.
// LESSON
SPAC investors funded a 10-year technology roadmap as if it were a 3-year product launch. The battery technology required for Lilium's 300km range didn't exist and couldn't be bought. Charismatic founders and rendered concept videos are not substitutes for physics.

🔥 Spotahome
Bad Timing
Spotahome built a platform for mid-term furnished rentals (1-12 months) targeting international students, expats, and digital nomads — all users whose movement required open borders and urban migration. COVID eliminated all three customer segments simultaneously: no international students, no corporate expats, no digital nomads. The company laid off 50% of staff in April 2020, pivoted to domestic rentals, and significantly scaled down.
// LESSON
When all your customer segments depend on the same macro condition (free cross-border mobility), your diversified customer base is actually a concentrated risk. Spotahome had students, expats, and nomads — and lost all three at once.
