Production AI apps, shipped in weeks.
re-entry is an AI app factory in Germany. We build the internal tools, document automation and assistants your team keeps postponing: scoped in one call, priced fixed, first demo inside two weeks, hosted in the EU or on your own servers.
The factory runs a limited number of build lanes. Join the waitlist and we email you when the next one opens.

Concept screens from the catalogue: a quoting tool, a document inbox, an assistant on your files. Yours is built to your workflow.
The cost arithmetic changed
A senior developer at a German agency bills €90 to €140 an hour, and a typical Mittelstand software project lands between €40,000 and €120,000 over a quarter or two of calendar. At those numbers, the tool that would save your sales team two days per quote stays unbuilt.
Coding agents changed the production method, and the arithmetic with it. A small senior team now carries what a whole project team carried: our engineers write the plan, the data model and the acceptance tests, supervised agent fleets produce the implementation, and the test suite plus an engineering review gate every merge. The calendar compresses from months to weeks, and the price is fixed before work starts.
Discipline is the point, because the last wave burned people: S&P Global found that 42 percent of companies scrapped most of their AI initiatives in 2025, largely pilots that never reached production.
Everything that leaves this factory is production software: typed code, tests, documentation and a named senior engineer signing every release.
What we build
Assistants on your documents
Answers across your wiki, tickets, drives and mail archive, with sources cited. Runs on EU servers or your own, and your data trains nobody's model.
Document automation
Invoices, orders and contracts read, extracted and posted into your ERP. A person confirms anything the system is unsure about.
Quoting and tenders
Apps that read the inquiry, match positions against your catalogue and draft the offer. Fraunhofer IAIS documents quote preparation dropping from two days to thirty minutes with this class of tool.
Customer service and triage
Email and ticket triage in German and English: sorted, drafted and escalated by rules you set, with a person on every send that matters.
Customer-facing MVPs
A product idea with a deadline. Auth, payments, admin and deployment, live in weeks and production-grade from the first release.
AI in your existing software
Customers ask for AI in your product: we build the feature in your stack, without a rewrite. And if an AI-built prototype collapsed before production, we rebuild it on foundations that hold.
How a build runs
Week 0
Scope call
Thirty minutes on the problem, then a written offer: scope, fixed price, demo dates. If the factory is the wrong tool for the job, we say so on this call and point you somewhere better.
Week 1
Plan and skeleton
Data model, integrations and a walking skeleton deployed behind a URL you can open. The plan and the acceptance tests are written by our engineers, not by agents.
Weeks 2 to 3
Our engineers orchestrate and review
Coding agents, Claude Code among them, work through the plan around the clock. Every change passes the test suite and an engineering review before it lands. You get a demo each Friday and a changelog in plain language.
Week 4
Hardening and handover
Security and failure testing, documentation, deployment to your infrastructure or to EU hosting we manage. The eval suite, test reports and an audit trail of every merge ship with the code.
A week-two build board. Agents produce, tests gate every merge, and our engineers sign the release.
The founder behind this
re-entry is founded by Kyle Nelson, a senior engineer based in Germany whose track record runs from building Debtist's collections platform to a €100 million exit. Before the factory, the team shipped an AI code review platform that engineering teams still run against their pull requests in production, and Fazit, a macOS app that turns calls into finished notes without audio leaving the machine.
The factory is that same pipeline pointed at your problem: the agent orchestration, review gates and test discipline built for our own products now build yours. You talk to the founder, and senior engineers review every merge from the first call to the handover.

Factory lane
€7,900
per month, stop any month
A standing lane in the factory: continuous building on a roadmap we shape together every month.
- One active build stream at all times
- Roadmap review monthly, demo weekly

If a build stops making sense partway through, you pay for the weeks delivered and keep everything built so far, including the repo.
Frequently asked questions
