We buildwhat otherscan't see
We ship AI-native products that work in production — not demos. Senior engineers, every engagement.NDA before hello. Remote-first since day one.
What we build
Services
Get a quoteWeb & App Development
Production-ready React and Next.js applications. From landing pages to complex SaaS platforms — architected to scale, designed to convert.
AI Integration & Automation
LLM-powered features that work in production. RAG pipelines, agent workflows, intelligent automation — shipped with real engineering rigor.
SaaS Product Design
Full-cycle product engineering. Strategy to deployment. Auth, billing, dashboards, multi-tenancy — we know the patterns because we build them regularly.
Cloud & DevOps
Infrastructure that disappears. AWS, GCP, Azure. Docker, Kubernetes, Terraform. CI/CD that makes deployment boring — which is exactly what you want.
API & Backend Engineering
REST, GraphQL, event-driven architectures. Built for reliability, observability, and developer experience. APIs your team will enjoy using.
Technical Consulting
Architecture reviews, code audits, team scaling. We look at your code and tell you honestly where it hurts — and what to tackle next.

What we've shipped
Logistics Corp, Hesse
Dispatch tool with AI-based classification of incoming orders. Replaced three separate Excel sheets and a Lotus Notes workflow. Claude API for categorization, FastAPI backend, React frontend. 380 users in three-shift operation, live since Q3 2025.

Migration from Shopify Plus to Next.js + Medusa. Checkout load time from 4.7s to 1.1s. Headless CMS for 4 languages, Stripe integration with local payment methods. Team of 2 engineers, 9 weeks.
Asset Manager, Frankfurt
Multi-tenant reporting dashboard for regulatory filings. TimescaleDB for time series, row-level security per tenant. Passed BaFin audit on first attempt. Reference available on request.
What we believe
Most agencies show you a Figma file and call it progress.
We have code running on a real domain by week one.
Speed without architecture means you pay twice — once to build, once to rebuild.
We do both in one pass.
AI demos impress investors. AI in production impresses users.
We build for the second group.
You don't notice good engineering.
You notice it when it's missing — and then it's expensive.
This is why we exist.
How we work
From hello to shipped.
No retainers. No vague estimates. A clear four-step process — first call to production.
Discovery Call
Free 30-minute strategy session. We scope your project, review your codebase if needed, and give you a straight answer on feasibility, timeline, and cost.
Proposal & NDA
Same-day written proposal — fixed scope, fixed price. NDA signed before we discuss a single line of your code. No hidden costs, ever.
Build Sprint
Focused 4-week engagement. Weekly video syncs, async Slack updates, daily code review. You see progress from day one.
Ship & Handoff
We deploy to production. You own everything — code, docs, infrastructure. Zero lock-in. Retainer available for ongoing work.
Client voices
What founders say
“We had two agencies before who each left us with half an MVP. SecretStack cleaned it up and shipped in 5 weeks. Only agency where I didn't feel like I had to translate between business and tech.”
“Honestly, I was skeptical — small team, no big name. But they made our Shopify checkout faster than our in-house team managed in 6 months. Numbers speak: 1.1s load time, conversion up.”
“They told me in the Discovery call that half my features were unnecessary. It annoyed me at first, then saved me €20,000. They do what they say, say what they do.”
The team
Built by engineers, led by operators
Ferdinand Bott

Former Big4 consulting, now prefers building things himself.
Sven Fischer
Operations & Projects
When a sprint goes sideways, he is the first to notice.
Christopher Schmitt
Tech & Architecture
Building backends for 10 years — started with Java, now TypeScript.
Benedict Schmitt
Finance & Contracts
Keeps us profitable and makes sure clients pay fair prices.

Common questions
All clear.
A focused sprint (4 weeks) starts at €8,500. A full SaaS product ranges from €25,000–80,000 depending on scope. You get a concrete fixed price in the Discovery call — no surprises on the invoice.
