Polyverse

Polyverse is a Bellevue, Washington company that describes itself as building a privacy-preserving AI data engine — positioned as a "decentralized Google" for the AI era — intended to form a large-scale global user data network in which data confidentiality is preserved while the data remains usable for AI training. Its stated privacy stack combines fully homomorphic encryption (FHE) with zero-knowledge proofs (ZKP), paired with blockchain-based incentives. The company markets a product it calls VerseOS, an AI data marketplace (ADM), together with a modular AI data architecture and an "AI data flywheel" concept describing a self-reinforcing data ecosystem. The data layer is presented as applicable to generative AI, decentralized AI, DeFi, DePIN, metaverse applications and large language models.

The company's earlier business was enterprise cybersecurity. Its flagship product, Polyverse Linux (also referred to as Polymorphic Linux), hardened open-source Linux distributions such as Ubuntu and Fedora against remote takeover by generating a slightly different, unique build of the operating system every 12 hours. This form of moving target defense targeted attacks that exploit memory bugs by continually altering the most likely targets within a customer's software stack, and was described as protecting systems even when unpatched. As of 2019 the company was preparing a Windows version of the product, aimed at both servers and desktops, with early releases expected later that year.
