After Twitter shut Posterous, the founder raised $500K to relaunch as Posterous Spaces — shut after 3 months when free users wouldn't pay for the same functionality
Fatal mistake: After Twitter shut Posterous in 2013, Sachin Agarwal relaunched as "Posterous Spaces" — a paid social posting service. Raised $500K. Shut after 3 months when it couldn't acquire a paying user base. The original Posterous had been free; users wouldn't pay for the same functionality. Shortest funded relaunch in this database.
Evaluating only Posterous Spaces’s profile at its peak — without knowing the outcome — the model ranked No market fit as the #1 likely cause. That’s exactly how it died.
