What Sdui offers

Strategic acquisitions
In July 2024, the Sdui Group acquired FoxEducation from GoStudent, Europe's largest tutoring provider.

In parallel, Sdui raised an additional €21 million, with a significant share allocated to the acquisition.
Founding story and growth
Sdui GmbH was founded in early 2018 by Daniel Zacharias, who leads the group today, and Jan Micha Kroll. The company evolved from a simple substitution‑plan app into a comprehensive communications and operations platform for schools and childcare institutions.
The COVID‑19 pandemic significantly accelerated adoption as school closures drove demand for secure, reliable digital tools. Today, Sdui positions itself among the fastest‑growing edtech providers in Europe, serving over 22,000 institutions while keeping compliant digitization at the core.
