Launch-ready SaaS MVPs designed for early paying customers — no throwaway prototypes, no enterprise consulting overhead.
Berlin teams come to us when the MVP has to do more than support the next round — it has to be ready for early paying customers and the next year of growth with reduced rewrite risk.
We design the architecture, build the launch core (auth, billing, role-based access, key product flows, CI/CD, monitoring), and hand it over in a state your in-house team can grow from.
Berlin has one of the largest funded B2B SaaS founder clusters in the German-speaking market — pre-seed and seed teams shipping out of Mitte, Kreuzberg, Charlottenburg and the corridors around Factory Berlin and Mindspace.
Add the EU-hosting requirements many of those founders' first customers will demand, the German procurement bar, and a tech-talent market where rewrite-trap mistakes are expensive — and you get a market where 'production-ready MVP' has a real meaning.
Architecture-first, EU-hosting options by default, designed to support early audit review and the first growth phase.
We pick the engagement shape that matches the stage of the MVP — from a 5-day architecture sprint to a fully embedded engineering partnership. Each shape is scoped up front; prices are indicative B2B ranges, plus VAT where applicable.
One senior engineer. A clear map of system boundaries, scaling risks, stack decisions, and a delivery roadmap — before a single line of production code. Day 1: discovery. Day 2: system mapping. Day 3-4: stack decisions and risk model. Day 5: roadmap and costed delivery plan.
Launch-ready core: auth, database, primary product flows, deploy pipeline, base monitoring. The foundation a Berlin SaaS team can take into early paying usage with lower architectural rebuild risk. We hand over a system your in-house team can extend, with documentation and runbooks.
Multi-domain product with structured DevOps, automated tests, observability and onboarding flows. Designed for funded teams that need to launch with paying customers, integrations and an editorial workflow — not just a logged-in demo.
Embedded senior engineering capacity. Monthly architecture reviews, scoped roadmap delivery, an external team that operates as part of yours. A common next step after the MVP ships.
Three Berlin-relevant engagements where the architecture decided whether the next year was shipping or firefighting.

We optimize for reducing rewrite risk during the first customer and growth phase. The trade-off is one or two extra weeks up front in exchange for lowering the chance of rewrite debt 12 months later.
Next.js / React on the front end, Java/Spring or Node.js on the back end, PostgreSQL with Redis where it earns its keep, AWS eu-central-1 or Azure West Europe for cloud, Kubernetes when it is justified by the scope. EU hosting options by default, GDPR-aware consent and data flows, no vendor lock-in baked into the architecture.
Yes — that is the typical engagement. The Architecture Sprint and MVP Foundation tiers are sized for funded pre-seed and seed teams. For pre-funded teams we recommend the Architecture Sprint as a standalone — it gives you a credible technical plan and costed roadmap to take to investors.
EU hosting is the starting point: AWS eu-central-1 / Azure West Europe / Hetzner / Mistral / EU-resident GPUs, depending on scope. We plan GDPR-aware consent and data flows plus sub-processor transparency for procurement review; final compliance depends on product, data types, vendors and legal review.
After the 5-day Architecture Sprint, the MVP Foundation tier is typically planned for 6–8 weeks and the Full Production MVP tier for 8–12 weeks. Both are scoped up front. We deliberately avoid open-ended scope — first release focuses on one workflow end-to-end, then we expand under the Engineering Partnership.
Many teams move into an Engineering Partnership: embedded senior engineering capacity from €4k/month B2B, plus VAT where applicable, monthly architecture reviews and scoped roadmap delivery. We operate as an extension of your team — not as a disconnected vendor. Hand-over to a fully in-house team is a documented path whenever you are ready.
Five days. €3,500 B2B, plus VAT where applicable. We map your existing systems and growth plan, name the architectural risks, and hand you a roadmap your team — or ours — can execute.
