01Sharpen the idea
Clarify the need, the users and the business model – and define what will show whether the idea holds.
Outcome
Clear criteria and a plan.
From idea to MVP
Know if the idea holds.In weeks.
Heey helps companies get new digital products off the ground. In a few weeks, a working prototype with real data shows whether an idea holds. It then becomes an MVP on a solid foundation – and your team takes over.
The starting point
New ideas have a hard time in companies.
Too slow.
Months pass before an innovation project even gets tested – alignment rounds, budgets, tenders. The market doesn't wait.
Stopped at sign-off.
The prototype works – but data protection and IT security won't approve it.
Pilots gather dust.
A prototype proves something – but far too often it stops there instead of becoming a product.
The knowledge leaves.
Externals build something – and the know-how walks out with the handover.
Approach
From idea to MVP.
2–6 weeks
02Test the prototype
A working prototype with real data and AI at its core – tried out by real users.
Outcome
A decision based on facts, not slides.
As needed
03Hand over the MVP
The prototype becomes a first market-ready version (MVP) – with sound architecture and security from day one. Your team or IT partner can develop and run the MVP seamlessly – no fresh start needed.
Outcome
An MVP your team takes over – no rebuild needed.
Fast and privacy-compliant.
Data sovereignty
Your data stays under your control – with processing in the EU and AI models that don't train on your data.
Privacy from day one
GDPR and data processing agreements considered from the start – not just before launch.
Experience in regulated markets
Banks, insurers and professionals bound by confidentiality, such as law firms and medical practices.
What gets built
From new products to AI agents.
New products
From business idea to a first market-ready prototype.
Apps
For customers or employees – mobile and on the web.
Automated processes
Recurring workflows that take care of themselves.
AI agents
Software that handles tasks on its own – traceable and under control.
New business models
Existing products rethought, with AI at the core.
Selected projects
From the first idea to millions of users – products built this way.
Fintech product
Gini
Snap the invoice, payment done: Gini developed photo payments and made them a standard in German banking. From the first prototype to integration into the apps of major banks and insurers – under strict security and privacy requirements.

Platform for coding agents
Verity
Verity runs a whole fleet of coding agents – from your phone, tablet or browser. Claude Code, Codex and open-source models work in parallel in isolated sessions on your own server. Credentials stay outside the agents, and every change goes through code review and checks before it is merged.

- Self-hosted

OCR & document extraction
Deep-OCR
Text recognition and data extraction for professionals bound by confidentiality: Deep-OCR turns contracts, invoices and medical reports into structured data – for law firms, tax advisors and medical practices. Processing happens in Germany and the EU, and documents are deleted right afterwards.
- Processing in DE/EU
- No storage
- § 203 StGB undertaking
Mobile App
Wavelength
Wavelength is like a password safe for development teams – on iPhone and iPad. The app opens the credentials teams manage in the Doppler service and makes them safe to use on the go: unlocked with Face ID, with no detour through other servers.
- Free on the App Store
- Face ID
- No trackers
Starting a company? Heey also works with founders – from the first concept to the prototype.

Who's behind it
Holger Teske
With Gini I turned an idea into a product for millions of people: the first prototype became photo payments in the apps of major German banks and insurers. Along the way I learned what it takes for something new not to get stuck at the concept stage.
That is what I do for others today – only faster, because AI is now part of the toolbox. I like nothing better than starting from a blank slate: where nothing exists yet and everything is possible.
With Heey you have one point of contact, from the first idea to the handover to your team. For larger ventures I bring in experienced partners from my network.
Contact
Let's talk about your idea.
A first conversation with me takes 30 minutes and comes with no obligation. Afterwards you'll know whether and how your venture can move faster.
For innovation, product and digital leads – and anyone who wants to get something new started.
I look forward to hearing about your project.
