European electricity market operator managing cross-border transmission capacity auctions

Utilities Hamm, Luxembourg 51–200 employees Founded 2008 Self-Owned

JAO runs the auction infrastructure for cross-border electricity transmission across Europe, operating 20,000+ auctions annually for 50+ Transmission System Operators. The tech stack is infrastructure-heavy (Terraform, Ansible, Postgres, Azure/AWS) with strong observability tooling (Datadog, New Relic, Elasticsearch), but active projects and pain points reveal a company in compliance and monitoring catch-up: NIS II implementation, KYC remediation, incident management, and service degradation tracking dominate the roadmap, suggesting regulatory pressure and operational scaling challenges outpacing current tooling maturity.
