Secure AI can still be simple.
We build AI solutions for sensitive data — from secure architecture to integration with existing workflows. We combine experience in regulated markets with a clear standard for UX.
Built for banks. Used by millions.
Our founder Holger Teske built Gini, developed photo-based payments and established them as a standard in German banking. It had to meet demanding security and privacy requirements — while remaining simple enough for people to enjoy using it. That experience shapes how we work at Heey today.
In production at
A third-country cloud is not an option for your data?
The prototype does not fit cleanly into your systems and processes?
In the end, it becomes just another tool instead of making work easier?
AI creates value only when privacy, confidentiality and data sovereignty remain intact, the solution is properly integrated and everyday work genuinely becomes easier.
When AI has to deliver more than a convincing demo.
Every industry has sensitive data — in personnel files, engineering drawings, contracts or health records. We bring AI safely into production there, too.
Sensitive data needs clear boundaries
We design architectures that make it clear where data is processed, how long it remains and who can access it.
Approval belongs in the project plan
We involve legal, privacy, information security and employee representation from the start — not just before go-live.
A pilot is not yet a product
We know integration, vendor assessments and operations from owning products ourselves — not just from consulting engagements.
Security must not get in the way
A solution creates value only when people choose to use it. That is why UX and security are part of the same product decision for us.
What this can become
Secure AI in everyday work
Process documents intelligently
Read, validate and route invoices, contracts and forms securely into the systems you already use.
Make knowledge securely accessible
Internal assistants answer questions from your documents — with clear sources and controlled access.
Automate workflows end to end
AI connects existing systems, handles routine work and keeps people in the loop where judgment matters.
AI consulting and delivery — from idea to production system.
We identify valuable AI opportunities, design secure architectures and build solutions that fit your processes and systems. Strategy, compliance, product and UX are considered together from the start.
Strategy tied to real value
We prioritise use cases with measurable impact — and clarify the data, systems and approvals they require early on.
Workflows, not isolated tools
We connect AI with your existing processes and systems, turning a useful feature into an end-to-end workflow.
From prototype to production
We build robust solutions, support integration and approvals, and make sure the value does not remain stuck in a pilot.
Sovereignty from day one
Data flows, retention, access and model choice become part of the architecture — transparent, documentable and tailored to your requirements.
Our standard
A solution succeeds only when it can be operated securely and makes people's work noticeably easier.
“Secure in operation. Simple in use.”
What we build ourselves.
Our products show how we work: secure architecture, simple experiences and clear value in everyday use.
Deep-OCR and Wavelength are built at Heey today.
Understand documents. Keep data sovereign.
Deep-OCR turns invoices, contracts, ID documents and bank statements into structured data. The API is quick to integrate, processes exclusively in the EU and is documented for professional secrecy requirements.

Manage IT secrets securely. On iPhone and iPad.
Doppler manages passwords and credentials for engineering and IT teams. Wavelength makes mobile access on iPhone and iPad faster, clearer and far more capable.

About Holger
Holger Teske founded Gini and developed photo-based payments together with his team.
He knows the full journey from product idea to operation in regulated environments: development, sales to major banks, vendor assessments and security reviews.
That experience shapes Heey. We combine strategy and execution, considering privacy, integration and UX from the very beginning.
Let's talk about your project.
Whether you have an initial idea, a stalled pilot or specific security requirements: our first conversation will clarify what is useful and realistic.
