Entropy, an Andreessen Horowitz-backed decentralized custody startup in the crypto industry, is completely winding down operations after four years and returning remaining capital to investors. The company, which had raised approximately $27 million, underwent two rounds of layoffs prior to its shutdown as it struggled to find a sustainable, venture-scale business model despite multiple pivots. Founder Tux Pacific announced the closure in January 2026, citing that the best efforts had been made, and the company could not achieve the necessary scale.
