Sonder Holdings
Sonder leased apartments and operated them as hotels, but the model required massive upfront investment in each unit while generating hotel-like margins — the worst of both worlds.

Root Causes
Key Lessons Learned
1. Lease arbitrage breaks in downturns
Sonder's model of leasing long-term and renting short-term works in boom times but creates massive fixed-cost exposure when occupancy drops.
2. SPAC valuations create impossible expectations
Going public via SPAC at a $2.2B valuation set growth expectations that the underlying unit economics could never support.
3. Hospitality at VC scale is rarely viable
The hospitality industry's thin margins (10-15%) fundamentally conflict with VC expectations of 10x+ returns on hundreds of millions invested.
