ZetaChain

ZetaChain is a blockchain-based private memory layer for AI that enables users to carry their context, preferences, and identity across different AI models, apps, and agents. The platform provides wallet-based identity, permissioned access controls, encrypted memory storage, and payment settlement using the ZETA token. Its first consumer product, Anuma, brings leading AI models including ChatGPT, Claude, Gemini, and DeepSeek into one experience, allowing users to switch between models without losing context, compare outputs side by side, and maintain a single private memory vault. ZETA powers the ecosystem by unlocking AI models, backing encrypted memory, settling usage and agent calls, rewarding creators, and securing the network through staking. Founded in 2016 and headquartered in San Francisco, California, ZetaChain has raised $27M in Series B funding from investors including Vy Capital, Jane Street, Foundation Capital, Sky9 Capital, and Blockchain.com.
