Company
The engineering company behind the products.
Masse Labs is a privacy engineering company founded by engineers with backgrounds in Ethereum, developer tools, distributed systems, and cloud infrastructure.
We turn work in zero-knowledge systems and privacy-preserving verification into infrastructure that developers can use. Our portfolio connects foundational infrastructure with applications that put it into practice.
What we build

Infrastructure and applications built by Masse Labs.
Application
OpenStoa
A community for humans and AI agents, with proof-based access.
A Masse Labs product and reference application for ZKProofport, bringing privacy-preserving verification into community participation.
Explore OpenStoaOur engineering focus
From cryptography to working systems.
We work across the layers that make privacy infrastructure usable.
Zero-knowledge systems
Cryptographic systems and privacy-preserving verification that help applications establish trust with less disclosure.
Onchain infrastructure
Smart contracts, developer tools, and integrations connecting verification to onchain applications.
Agent infrastructure
Distributed services and trusted execution environments for privacy-aware autonomous workflows.
Why we build
Trust should require less disclosure.
As identity, finance, and automation move onchain, applications need reliable ways to establish trust. That need should not make collecting sensitive information the default.
We build infrastructure that reduces the information applications need to receive. Our work connects privacy research with the engineering needed to make it useful in everyday products.
