Everything from one team.
Architecture, development, cloud, mobile, design, AI integration — one partner for the full software journey, instead of coordinating three vendors.

Solutions
Where we help most often.
Three situations in which mid-sized businesses typically approach us.
Situation 01
Your software comes from a different era.
Legacy system, on-premise, hard to maintain. You want to modernise — without putting current operations at risk.
Legacy modernisationSituation 02
You have an idea. The team is missing.
A product idea with market potential — but no in-house developers. You need a team, without committing to full-time hires.
Build the productSituation 03
Your project is on fire. You need reinforcements.
Internal team overloaded, know-how missing, project in crisis. You need senior help now — hourly, without lock-in.
Team augmentationWhat you get
Four promises that define our work.
Four outcomes that define every engagement with Tech42 — and against which the value of our work can be measured.
Built future-proof.
Software that is still maintainable and extensible in five years. Clear architectures, documented decisions, clean code quality.
Faster to market.
We start with a focused MVP and engage real users early. Productivity emerges in controlled steps — without big-bang risk.
Economically sustainable.
Software that holds its value over years — low maintenance costs, controlled cloud spend, clear ROI arguments for your investment case.
AI in our engineering process
Modern tooling. Senior accountability.
Artificial intelligence is a core part of our engineering practice. We apply it consistently — for faster delivery, shorter iteration cycles, and higher code quality. What AI does not take on is responsibility for architecture, security, and the stable production operation of your systems. That responsibility sits with a senior engineer as your dedicated project lead — and with Tech42 as your contractual partner.
Why Tech42
Reliability. Competence. Honesty.
Three values our work is measured by — from the first conversation to years after a project ends. That's what our clients pay us for.
01
Reliability
We say what we do. And we do what we say. On time, at quality, with clear communication. Our best client relationships have lasted years — because our clients always know where things stand.
02
Competence
Senior-only. Experienced engineers, architects, and tech leads — permanently employed, personally known, proven across multiple projects. Deep .NET and Azure expertise, clean architecture, clear technical decisions — even when they're inconvenient.
03
Honesty
We give you honest assessments — on feasibility, effort, and the right approach for your project. Clear words instead of a simple sales pitch. Long-term partnerships grow from exactly that openness.
Services
Seven services around custom software development.
From custom software development to cloud architecture and mobile apps to AI integration — the full software journey from one team, delivered in German quality. One team from Hamburg.
What clients say
A strategic partnership — eye to eye.
Our clients see us not as a vendor but as an extension of their own team.
We see Tech42 not as a traditional vendor, but as a strategic technology partner on equal footing.
The quality and know-how are exceptionally good and satisfying.
Let's talk about your project.
No-obligation first call. We listen, give an honest take, and suggest the next move — even if it's not with us.
