Products in production
Four products, each solving a real problem end-to-end — and each a proof of how we build.
// 01 · Inbox AI
BJ Assistant
A Microsoft 365–native inbox AI. It drafts in German, English and French in the formality your reader expects, triages what’s urgent with reasoning you can audit, and pushes only what matters to WhatsApp — plus meeting and flight briefings and automatic focus-time scheduling.

AI & technology, from strategy to production
We advise companies on integrating AI and technology — and because we build our own products, our advice comes with the ability to deliver it.
Integration
We wire AI and modern technology into the tools you already run — Microsoft 365, your ERP, your data — so it fits your operations, not the other way around.
Delivery
From prototype to production. We don’t just advise — we build, ship and run the software, the same way we run our own products.
// The way we work
From idea to running software
01
Discover
We learn your business, your constraints and your data, and pinpoint where AI and technology create real leverage.
02
Build
We design and build the product — fast, iteratively, with working software in your hands instead of slideware.
03
Run
We ship to production and keep it running — monitoring, iterating and scaling as your needs grow.
// Who we are
A studio that ships
BrettlJausn is a small, product-minded team. We hold ourselves to the same bar we set for clients: real software in production, hosted in the EU, built to be audited and to last. Every product on this page is something we run ourselves — which is exactly why our advisory work moves from slide to shipping code.
Whether you adopt one of our products or bring us a problem of your own, you get a partner who builds.
