Berlin, Germany · Europe/Berlin
Berlin — GDPR-first by default.
Berlin engagements lean heavily into B2B SaaS and fintech. The defining constraint is GDPR — every architectural decision needs to hold up to a DPO's review. We build with that posture from day one: encryption at rest, data-residency-aware deployments, audit trails sufficient for ROPA, and the engineering paperwork that BaFin or similar regulators will eventually ask for.
Working with Berlin-based teams
- Working hours overlap fully with CET
- EU data-residency on request (Frankfurt regions, EU-hosted providers)
- GDPR DPA in addition to the engineering contract — standard offering
- Familiar with German invoicing requirements (USt-ID, EU-VAT reverse charge)
Where we focus in Berlin
Our most common engagement shapes for teams in this market.
SaaS
Vertical or horizontal SaaS — the back-office, the product surface, the billing, the dashboards, the integrations. Where most of our work lives.
Fintech
Banking infrastructure, payments products, lending platforms, embedded finance — every one of them lives or dies on the quality of its integrations and compliance posture.
Marketplaces
Supply, demand, fee model, escrow, KYC, dispute flows. Marketplaces have the most operational surface area per founder of any category we build.
Media & publishing
Editorial platforms, subscription paywalls, content recommendation, ad ops integration. SEO and performance dominate the engineering brief.
Edtech
Learning platforms, tutoring marketplaces, course delivery, school operations. The audience is generally non-technical and uptime is mostly a school-day thing.
