CUSTOM AI DEVELOPMENT

Custom AI Development You Can Trust

We are a team with more than 20 years in custom software engineering. We build private RAG, AI assistants, and custom models on infrastructure you control, for companies in the US and EU. Your data stays yours.

What We Build

One Team for the AI You Need to Ship

Hire developers who build the whole system, not a tool you have to assemble yourself. We bundle these capabilities into a single custom build, scoped to your problem.

Why Ironum

Two Decades of Engineering, Now Applied to AI

Your data stays yours

Every system runs on infrastructure you control. With open-source models, nothing is sent to third-party providers, no leakage, no training on your data, no lock-in.

Competitive nearshore pricing

German engineering standards delivered by teams in Germany and Poland, at nearshore rates. Cost-competitive with offshore options, in EU time zones, under EU contracts.

Proven by real work

More than 20 years building custom software, now applied to AI. We have shipped production systems for FH Dortmund, Smella, and LearnSlice. Built by engineers, not PowerPoint.

Compliance when you need it

EU data residency, GDPR Data Processing Agreements, audit logging, and EU AI Act documentation available on every build, ready for US companies serving EU customers.

Selected Work

Where We Have Delivered

A few of the production systems we have built. Each one started as a custom engineering problem, not a template.

HOW IT WORKS

From First Call to Production

01

Discovery & Scope

A free call to map your data, infrastructure, and goals. We come back with a clear scope, timeline, and fixed price.

02

Proof of Concept

A working prototype on your actual data, deployed in your environment in about two weeks. You see results before the full build.

03

Production & Handover

Full rollout with monitoring, documentation, and training. You own the code and models. Ongoing support if you want it.

Pricing

Fixed Scope. Transparent Price.

Most projects start with a focused proof-of-concept, then a fixed-price production build. Because our teams are in Germany and Poland, you get senior EU engineering at rates that stay competitive with offshore, without sending your data offshore.

Frequently Asked Questions

We build production AI systems tailored to your data and processes: private RAG and knowledge search, AI assistants and chatbots, fine-tuned open-source models, and automated workflows and agents. Everything runs on infrastructure you control, and you keep the code and models we build. We are software developers who build AI solutions, not a SaaS you rent.

Yes. We deploy on your infrastructure, your cloud account (Azure EU, your own AWS/GCP), German-hosted Hetzner, or fully on-premises. With open-source models the entire pipeline runs on your hardware, so your data is never sent to third-party model providers. That is the default, not an add-on.

Our engineering teams work across Germany and Poland. You get German engineering and project standards at nearshore rates, in EU time zones and under EU contracts. For US companies that means a partner who is cost-competitive with offshore options while keeping data inside trusted EU jurisdiction.

Yes. We build on open-source foundations (Llama, Mistral, n8n, Qdrant and others) and hand over the code and model artifacts. No black boxes and no vendor lock-in. You can run, extend, or move the system without depending on us.

Through real work, not slideware. Our team brings more than 20 years of custom software engineering, and we have shipped production AI for FH Dortmund, Smella, and LearnSlice. We start most engagements with a working proof-of-concept on your actual data within about two weeks, so you see results before committing to a full build.

When you need it, yes. EU data residency, a standard Data Processing Agreement, audit logging, and EU AI Act documentation are available on every build. We treat compliance as a capability you can switch on, not the only reason to hire us.
