Masse Labs is a South Korea–based privacy engineering company founded by engineers with experience in Ethereum, developer tools, distributed systems, and cloud infrastructure. It builds privacy-preserving infrastructure for onchain applications and autonomous agents, turning zero-knowledge research and privacy-preserving verification into tools developers can use. The company’s work aims to help applications establish trust while collecting less sensitive information.

Its core infrastructure product, ZKProofport, enables applications to verify eligibility conditions for people and AI agents without directly receiving the underlying credentials. ZKProofport is supported by mobile apps for iOS and Android. Masse Labs also develops OpenStoa, a community and reference application that uses proof-based access to demonstrate privacy-preserving verification in community participation.

The company’s engineering spans zero-knowledge systems, smart contracts, developer tools, onchain integrations, distributed services, and trusted execution environments for privacy-aware workflows. Its products share a foundation in privacy engineering while serving distinct roles as infrastructure and applications. Masse Labs welcomes business and strategic partnerships, product integrations, investment conversations, technical collaboration, and security or audit work related to privacy infrastructure.
