Stop renting. Software your company owns — not the other way around.
AI-Assisted Development (AAD): industrially built software that experienced developers and product owners build together with you, along your processes — in your own Azure tenant.
The status quo is becoming a competitive disadvantage.
Companies pay on average around €4,450 per employee per year for SaaS — with double-digit annual growth. Every tool solves one problem; together they create a bigger one: data and knowledge leave the house, people jump between dozens of apps, and every contract deepens the dependency. AAD turns this around — secure & uptime by design, in your own tenant. We start with one clearly scoped use case and replace a bundle of 3–5 SaaS tools.

The lever is the use case — not your company size
One app replaces 3–5 of a team's SaaS tools. The build is one-time; SaaS runs forever and rises every year.

You pay more than just the license
Eternal rent
+21.9% per year — without any added value driver.
Lock-in
53% feel at their vendors' mercy on price and contract.
Forced renting
60% use the cloud because software is only available for rent now.
Data out of house
Knowledge grows at the vendor, not with you.
Tool sprawl
Dozens of apps, breaks and friction in everyday work.
The AI writes the code — control stays with you
Identity from your tenant
Entra ID & Key Vault. The AI only writes the code — access and secrets stay with you.
No data leakage
GDPR-compliant in your own tenant. Data, knowledge and control stay in-house — no US dependency.
Managed security
Shared responsibility: Azure Managed Services handle patching, hardening and availability.
An industrialized process — not a prompt gamble
7+ tools → 1 learning app
- 7+ separate tools
- Knowledge leaves the house
- Every deal starts from zero
- 1 integrated app
- Knowledge Graph in-house
- Every deal makes you smarter

Frequently asked
Will we then depend on you?
No. The app runs in your tenant, the code is yours, the standards are open. We build with you — not to lock you in.
What if our requirements change?
That's exactly what AAD is built for: apps follow your processes — not rigid rental features. Change is part of the model.
Is it secure enough for us?
Identity via Entra ID, secrets in Key Vault, GDPR-compliant, managed security. Secure & uptime by design — no data leakage.
Does it already pay off for a small team?
Clearly from ~50 users or 4 replaced tools. We show very small cases openly in the table — we don't promise anything that doesn't add up.
Start small, think big — the self-building company
The goal is a shared data grid for all apps and people. Every app feeds into it.
One team, replace a bundle of 3–5 tools — your first own app in the tenant.
More use cases — the shared data grid grows.
Replace large platforms — the potential grows, the ROI stays stable.
Replace one tool bundle — start a pilot.
Pick one clearly scoped use case from your stack. We'll rebuild a bundle of 3–5 SaaS tools as your own app in your tenant — your data, your knowledge, your control, from day one.
