**Type:** Problem & solution

## Summary

Evenpay develops compensation transparency software to meet the EU Pay Transparency Directive, requiring strict safeguards for sensitive employee salary data. The startup initially selected a lightweight B2B authentication platform for quick onboarding, but soon encountered unmet data residency and compliance demands from Finnish enterprise clients. To resolve these limitations, Evenpay migrated all customers to Auth0 over a few weeks using documentation and AI assistance. Adopting Auth0 allowed the team to fulfill regional EU data controls while reducing managed Single Sign-On setup times from weeks to as little as one day through self-service options. Furthermore, relying on an established authentication brand provided instant credibility with enterprise security officers without requiring custom authentication development.

## Context

Evenpay, a compensation transparency startup handling sensitive employee salary data under the EU Pay Transparency Directive, encountered strict data residency and compliance requirements from Finnish enterprise customers. Their initial startup-focused B2B authentication provider lacked support for the necessary EU data controls and configuration flexibility.

## Approach / What changed

The team migrated all customers to Auth0 over several weeks using documentation and AI assistance. They adopted Auth0 to satisfy EU data residency needs and implemented self-service Single Sign-On (SSO) configuration for customer IT teams.

## Takeaways

- Evenpay migrated its authentication system to Auth0 within a few weeks, relying on documented support materials and AI tools to manage the process.
- Adopting Auth0's self-service SSO setup reduced customer onboarding timelines from weeks of IT email exchanges down to as little as a single day.
- Using an established identity provider rather than custom-built auth helped the startup satisfy Finnish data residency rules and establish credibility with enterprise security buyers.
