Financial Services Berlin 501–1,000 employees Founded 2020 Privately Held

Unzer operates a payments and point-of-sale ecosystem serving 85,000+ merchants across four European countries. The tech stack reveals a mature data and security posture—Kafka, Airflow, dbt, Redshift, PostgreSQL, Kubernetes—paired with heavy investment in compliance and risk frameworks. Hiring momentum has decelerated, but headcount leans heavily toward security (12 open), finance (10), and sales (9), reflecting the operational reality of managing tax, regulatory, and incident-response requirements across fragmented European jurisdictions.
