## 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](https://startwithidentity.com/standards/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](https://startwithidentity.com/tools/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](https://startwithidentity.com/vendors/decentralized-identity/walt-id/); for an aggregation-style acceptance layer consider [Trinsic](https://startwithidentity.com/vendors/decentralized-identity/trinsic/); browse the full [decentralized identity category](https://startwithidentity.com/vendors/decentralized-identity/) for peers.

## Bottom line

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