a16z-Backed Blockchain Gaming Studio Proof of Play Shuts Down, Cites Failure to Build Sustainable Business

Aug 5, 2026

US blockchain game developer Proof of Play is ceasing operations after failing to build a sustainable business around its fully on-chain gaming thesis. Despite raising $33 million in 2023 from a16z and Greenoaks, and achieving massive transaction volumes on its flagship game Pirate Nation, the studio could not transition speculative player activity into long-term retention. Proof of Play is open-sourcing its code and releasing its art assets under a CC0 license, while the independent Pirate Nation Foundation will take over support for the PIRATE token.
