Root Causes
Zirx offered on-demand valet parking; GhostRuck on-demand moving. Both raised total ~$45M combined. Both discovered that stationing labor for demand-uncertainty is expensive, and consumers only used them at deep discounts. Zirx pivoted to enterprise parking in 2015; GhostRuck folded 2016. The on-demand cohort represented a whole class of doomed unit economics.

1. Frequency matters in on-demand

2. Category convergence is a signal
When multiple 'Uber for X' companies fail in the same quarter, the entire assumption pool is wrong.
