Founder & managing director
Engin Yildirim
Engin Yildirim has been building software for more than 13 years – first business applications as an employee, later his own online services. With BlitzFast he brings these products together under one roof.
The motivation is always the same: build tools that solve a concrete problem and are understandable without training. And run them so that customers don't have to think about data protection, because we already have.
BlitzFast looks after the entire technology itself, from the servers to the user interface. That keeps things direct: whoever has a question talks to the person who built the product.
How we work
Operated in Germany
Our services run on our own servers in Germany. No third-party cloud, no data export.
Direct contact
One email is enough. Replies usually within two working days, from the founder personally.
Honest products
No features that don't exist yet. If something isn't working, we say so openly – with a solution.
Custom development on request
Alongside our own products we build custom software for businesses on request: from the first idea through a prototype to day-to-day operation. We work in short steps so you see results early and costs stay predictable.
