Entropy was a US decentralized crypto custody startup founded in 2022 and led by CEO Rich Pacific, backed by Andreessen Horowitz's a16z crypto with ~$25M raised. It built multi-party-computation (MPC) custody tools aimed at institutional and DeFi-native users. In early 2026 Pacific announced the company would wind down operations and return remaining capital to investors, saying Entropy's latest product had failed to hit venture-scale growth metrics and the choice was between yet another pivot or shutting down (The Block, Cointelegraph, crypto.news, Yahoo Finance). Entropy is cited alongside other 2024-26 a16z-backed crypto shutdowns as evidence that decentralized custody remains a hard market to crack against Coinbase Prime, BitGo and Fireblocks.
