Berlin teams come to us when the MVP has to do more than win the next round — it has to survive the first 100 paying customers and the next year of growth without a rewrite. We design the architecture, build the production 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. Not a throwaway prototype, not an enterprise consulting overhead.
Berlin holds the largest concentration of funded B2B SaaS founders 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 requirement most 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-hosted by default, designed to survive the first audit 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 fixed-scope, fixed-price up front.
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.
Production-ready core: auth, database, primary product flows, deploy pipeline, base monitoring. The foundation a Berlin SaaS team can take to its first 100 paying users without an architectural rebuild. 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, SLA-bound roadmap delivery, an external team that operates as part of yours. The engagement most Berlin teams move into after the MVP ships.
Three Berlin-relevant engagements where the architecture decided whether the next year was shipping or firefighting.

We optimize for surviving the first 100 paying customers and the first growth phase without a rewrite. The trade-off is one or two extra weeks up front in exchange for not paying off 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 by default, GDPR-aligned 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.
By default. EU hosting (AWS eu-central-1 / Azure West Europe / Hetzner / Mistral / EU-resident GPUs), GDPR-aligned consent and data flows, sub-processor disclosure ready for your customer's procurement team. We design the data path so a German enterprise customer can sign it.
After the 5-day Architecture Sprint, the MVP Foundation tier ships in 6–8 weeks and the Full Production MVP tier in 8–12 weeks. Both are fixed-scope, fixed-price up front. We deliberately avoid open-ended scope — first release ships one workflow end-to-end, then we expand under the Engineering Partnership.
Most Berlin teams move into an Engineering Partnership: embedded senior engineering capacity from €4k/month, monthly architecture reviews, SLA-bound 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.
We ship out of Berlin into the other markets with on-site kick-off, the Architecture Sprint on the ground, and live pair-time through implementation.
Five days. €3,500. We map your existing systems and growth plan, name the architectural risks, and hand you a roadmap your team — or ours — can execute.
