Avisi celebrates 25 years

Avisi has officially turned 25. What began with three founders and an idea has grown into an organisation full of driven professionals, great clients and innovative projects.

For a quarter of a century, the Arnhem-based software company has been helping organisations with their digital transformation. Avisi develops software for, among others, the notarial chain, the mortgage chain and the energy sector. Almost every Dutch citizen comes into contact with software developed by Avisi at some point.

Founders Jan Bakker, Barri Jansen and Gert-Jan van de Streek joined DEC-Alliance with Avisi and iDalko in July 2024, as the very first companies to do so. A deliberate choice for continuity: growing and innovating while retaining independence, in an alliance of entrepreneurs who build for the long term.

Twenty-five years of craftsmanship is exactly the kind of foundation DEC-Alliance stands for. Our warmest congratulations to Avisi. Here's to the next 25 years.
