Keypo

FOUNDER & CEO

Hardware-secured, privacy-preserving developer tools for AI and crypto applications. Our products include: - Keypo CLI: key management for AI agents. Keypo CLI enables AI agents to use secrets (API keys, credentials, credit cards and crypto wallets) without having access to them in plaintext. Secrets are hardware-bound to Mac Secure Enclave passkeys with fine-grained usage policies. 170+ GitHub stars. - Keypo App: seed phrase recovery app that splits your seed phrases across multiple devices using Shamir Secret Sharing and Secure Enclaves. - Keypo SDK: decentralized encryption SDK for building applications that put their users in full control over their data.

FOUNDER & PM

Token-gated interactive experience for director Michael Mann's filmmaking archive, beginning with Ferrari. Featured on the LA Times.

OpenClaw XMTP

DEVELOPEROPEN SOURCE

Built OpenClaw integration with decentralized messaging protocol, XMTP, to enable serverless E2EE messaging with OpenClaw AI agents.

AI Agent Wallet

FOUNDERDEVELOPER

Most agent wallets use cloud secure enclaves to protect keys and enforce rules. Keypo uses your Mac's Secure Enclave and EIP-7702 smart accounts - same security, fully self-custody. Your agent can do anything onchain, but no one (including your agent and Apple) can extract your keys. Add programmable rules like spend limits and allowlists to control exactly what your agent can and can't do.
