Paack
Spanish sustainable last-mile delivery startup backed by UPS and Tiger Global that raised 180 million euros and entered zombie mode as unit economics failed to converge.
Evaluating only Paack’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
Paack raised €180M from UPS Ventures, Tiger Global, and others to build a sustainable last-mile delivery network across Spain, France, Portugal, and the UK using scheduled time-slot deliveries to improve efficiency. The scheduled delivery model reduced failed delivery rates but required expensive coordination infrastructure. Tiger Global marked down its portfolio. UPS exited. Paack conducted significant layoffs in 2023 and entered zombie mode, unable to demonstrate profitability at scale against established logistics giants with better infrastructure economics.
Lesson
“Last-mile delivery innovation requires achieving delivery economics better than established postal operators. Scheduled delivery windows improve customer experience but add coordination costs that make the economics worse, not better.”
