Gataca

Overview

Gataca, founded in 2017 and based in Madrid, builds self-sovereign identity software: a mobile wallet, a credential issuer, and a verifier, with a clear bet on the European digital identity (EUDI) wallet program. It is a small, region-focused vendor in an emerging market rather than a broad IAM platform, and its trajectory is tied closely to how the EUDI rollout under eIDAS 2.0 unfolds.

What it is good at

The strength is alignment with European regulation and standards. Gataca implements W3C Verifiable Credentials and DIDs, supports OpenID for Verifiable Credential Issuance and Presentation (OID4VCI and OID4VP), and packages wallet, issuance, and verification as one coherent stack so a European organization can pilot an EUDI-style flow without assembling components from scratch. It offers both SaaS and self-hosted deployment, which matters for public-sector data residency.

Where it falls short

It is geographically concentrated and early stage. Outside the EU there is little reason to choose it, the verifier and relying-party network is small, and authorization, SSO, lifecycle, and governance are thin next to mainstream IAM. Like the whole category, real cross-organization credential exchange is still nascent, so expect pilots rather than mass adoption.

Pricing

Subscription and project-based, sales-led, with no fully public pricing. Model total cost against your actual issuance and verification volumes with the TCO calculator.

Best for, and who should look elsewhere

Choose Gataca if you are a European organization or government body building toward the EUDI wallet and want a packaged SSI stack. Look elsewhere if you need a global, developer-first platform or broad enterprise IAM features. For open-source tooling consider walt.id; for an aggregation-style acceptance layer consider Trinsic; browse the full decentralized identity category for peers.

Bottom line

A credible EU-aligned SSI option, strongest for EUDI-driven public-sector and regulated projects, narrow everywhere else.
