su.engineering: independent product and engineering studio in Bilbao. Identity, privacy, AI, security, distributed systems.

We design and build software for hard technical problems.

su.engineering is an independent product & engineering studio in Bilbao, Basque Country. We help companies, system integrators, enterprise teams and research consortia design and ship technically difficult software.

project work

  • Identity & EUDI: wallets, issuers, verifiers, credentials and interoperability.
  • Product Engineering: from ambitious technical idea to working product.
  • Specialist Partner: senior engineering capability inside your existing project.

We stay small and senior, and build the team around the problem: from one specialist to a full delivery team. Our team brings experience from 30+ enterprise projects, including work before founding su.engineering.

products

We build what we advise on.

Product Status What it is
Velum Live Privacy infrastructure for everyday AI workflows. Keeps sensitive information from being exposed to AI tools and other external services.
OpenKYC Approaching launch Reusable identity verification without repeating KYC. Credential-based identity and age verification built on reusable proofs.
REM In development Shared engineering memory for teams working with AI agents, across developers, repositories and coding tools.
Klangfarbe In development Verifiable identity for AI voice agents. An open protocol that lets the receiver of a call check which organization's agent is speaking and for what purpose.
