Architecture-led MVPs and scoped product builds for funded teams that need a credible version one — without seeding rewrite debt. We design the system, build the core, and hand it over to your in-house team in a state it can grow from.
Architecture-First Engineering Services
Senior engineers and 5-day Architecture Sprints for funded B2B SaaS startups and Mittelstand teams. Built to survive growth — not to be rewritten.
Every engagement begins with an Architecture Sprint
Five working days. One senior engineer. A clear map of system boundaries, scaling risks, stack decisions, and a delivery roadmap — before a single line of production code.
- 01Day 1
Discovery: domain, constraints, growth targets
- 02Day 2
System mapping: services, data, integrations
- 03Day 3-4
Stack decisions and risk model
- 04Day 5
Roadmap & costed delivery plan
Five engineering clusters
One commercial entry layer. Specialised audits, migrations, and narrower formats live below as the second layer.
Backend systems, APIs, event flows, and architecture decisions for products that need reliability proven before scale exposes the cracks. We work where domain logic, data integrity, and integration complexity decide whether the next year is shipping or firefighting.
Web platforms, product interfaces, design systems, and frontend delivery for systems where UX and engineering can't be solved separately. Built on a modern Next.js / React stack, optimised for SEO, conversion, and editorial speed.
Cloud infrastructure, deployment pipelines, observability, and resilience work for teams that need delivery and operations to scale together. From CI/CD setup and Kubernetes to monitoring — one engineering discipline, not five separate vendors.
Data pipelines, AI workflows, CRM logic, and operational integrations that turn disconnected tools into systems people actually use. We build automation that holds up in production — not demos that fall over the second a real workflow hits them.
What teams come to us with
Each scenario maps to one of the five clusters above — every link below stays inside the architecture, no orphans.
We’re stuck with a fragile MVP
The product works, but every change breaks something.
Our system doesn’t scale anymore
Traffic, data, or users grow — reliability doesn’t.
We need to pass audits / compliance
Security, GDPR, data flows, and traceability must hold under review.
Our analytics can’t be trusted
Decisions are made on dashboards nobody fully believes.
We’re rebuilding too often
Rewrites slow the roadmap and kill momentum.
Audits, migrations, and focused engagements
Specific delivery formats for existing systems — when you do not need a full build, but a precise intervention.
Architecture & DevOps Audits
System-level audits with prioritised findings, risk analysis, and a costed action plan. For teams considering a build, a rewrite, or a fundraising-grade due diligence.
Platform Support & Maintenance
Structured ongoing development and SLA-ready operations for complex platforms with multiple stakeholders. Senior engineers, not ticket queues.
Migrations & Relaunch
SEO migrations, platform modernisation, and technical relaunches without ranking loss or downtime. Phased delivery while operations stay live.
Performance Optimisation
React performance, Core Web Vitals, and system-level scalability work. Backed by measurement, not vibes.
Same engineering discipline, different industry complexity
Architecture principles hold across verticals. What changes is data structure, compliance, and integration depth.

Engineering that survives the first 100 paying users
Pre-seed to Series A teams that need the production-ready foundation — before the product rewrites itself.
B2B SaaS · Funded Startups
Modernise legacy systems without a full rewrite
Phased migration for established German companies. Operations stay live while the new architecture comes online.
Mittelstand · Modernisation
Compliance-driven backends, payments, risk pipelines
Where regulatory load, data integrity, and audit trails decide whether the system passes review.
FinTech & Financial Platforms
B2B platforms, configurators, document control for OEMs
Multilingual catalogs, spec packages, and structured data flows for engineering-heavy organisations.
Industrial EngineeringWhat makes the engagement different
Built to reduce rewrite risk at seed-stage growth
Most agency MVPs need a rewrite by the time the product hits real traffic. Ours rarely do, because we treat architecture as the first deliverable — not as something the next team will figure out.
Named senior engineer from day one
You work directly with the engineer designing your system. No account managers, no offshored execution, no “let me check with the team and get back to you”.
Code written to be handed over
Every engagement is built on the assumption your in-house team takes ownership eventually. Documentation, structure, and naming are part of the deliverable — not afterthoughts.
Architecture defined before first feature
We refuse to start a build before system boundaries, data flows, and scaling risks are mapped. The 5-day Architecture Sprint exists exactly so the next 9 months don't get rebuilt.
Questions teams ask before signing
Five working days with a senior engineer. You leave with a system map, scaling-risk model, stack and infra decisions, and a costed delivery roadmap. Fixed scope, fixed price, no commitment to continue.
Both. Architecture Sprints and audits are always fixed scope. Build engagements typically start with a costed roadmap from the Sprint, then run as monthly retainers with named engineers — so capacity is predictable on both sides.
Senior engineers, named from day one and stable across the engagement. We do not subcontract delivery to junior offshored teams. The engineer who designs your system is the one writing the code or owning the team that does.
Both. We frequently embed alongside in-house teams — leading architecture, owning specific subsystems, or running a contained workstream like a migration or a performance pass — without taking the whole product over.
Standalone Architecture & DevOps Audits are one of our most common engagements. Two to three weeks, written report, exec readout, and a prioritised action plan. Often used before fundraising or a build vs rewrite decision.
Handover is treated as a deliverable, not a courtesy. Documentation, architecture diagrams, runbooks, and onboarding sessions are part of every engagement. We assume your team takes ownership eventually — that assumption shapes how the code is written.
