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's Senate describes the city as Germany's largest startup location and identifies SaaS/AI among its central sector strengths. That makes Berlin a relevant market for funded product teams moving from a demo toward paying users, integrations and more formal procurement.
Our delivery position is narrower than the ecosystem claim: architecture-first SaaS MVPs with EU-hosting options, documented handover and a foundation designed to reduce avoidable rewrite risk during the first growth phase.
The appropriate format depends on how much has already been validated, what must be ready for the first release and who will own the product afterwards.
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.

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.
If the product needs continuous development after launch, a follow-on phase can cover prioritised product work, architecture decisions and operational improvements. A documented handover to an in-house team remains an available path.
Tell us what has already been validated, what the first release must support and who will own the product afterwards. We can then define a suitable technical and delivery scope.
