Sdui Group secures strategic Investment to accelerate its Mission to become the Operating System for European Schools

Juli 21, 2025

Sdui Group, a leading European provider of cloud-based administrative software for K-12 schools, today announced a new growth investment led by Bain Capital’s Tech Opportunities fund, with participation from existing investors HV Capital and High-Tech Gründerfonds (HTGF).

The funding will be used to strengthen Sdui Group’s product suite, deepen its support for educational institutions, and further its ambition to become the unified digital platform for education in Europe.

Founded in 2018 in Germany, Sdui Group provides a fully integrated suite that supports schools across administrative needs from communication, attendance, scheduling, grading, and more. Today, Sdui Group serves thousands of institutions across Germany, Austria, Switzerland, and Spain, and is continuing to expand into new regions. Its modern, modular software is trusted by individual schools, districts, and governments to streamline operations. Sdui Group’s suite improves the experience for all stakeholders – teachers, students, administrators, and parents – and gives back valuable time to focus on teaching and learning.

As European school systems face rising complexity, increased digital expectations, and expanding public support and funding for education technology, institutions are looking for modern, reliable platforms that simplify their daily workflows. With a user-first approach and scalable, compliant cloud architecture, Sdui Group is well-positioned to lead this shift.

“This is a moment of transformation for education in Europe,” said James Stevens, a Partner in Bain Capital’s Tech Opportunities business. “Sdui Group is emerging as a trusted and capable partner to help schools navigate that change. Daniel and his team have built a modern, intuitive platform that directly addresses the daily challenges of school administration. We’re excited to support their continued growth and impact across the region.”

Sdui Group has already built strong momentum through both organic growth and acquisitions. The company has successfully integrated several regional software players, expanded its capabilities, and continues to invest in innovation, reliability, and user experience. “Bain Capital’s approach is unique – they combine strategic vision with real operational support,” said Daniel Zacharias, Founder and CEO of Sdui Group. “They’ve taken the time to truly understand our mission and the realities schools face every day. With their support – and the continued backing of HV and HTGF – we’re accelerating our work to build the digital backbone of European schools.”

“We’ve been proud to back Daniel and Sdui Group since the early days and are thrilled to continue supporting this next phase of growth,” said Felix Klühr, Partner at HV Capital. “Bain Capital’s experience scaling software companies globally makes them a valuable addition to the partnership.”

Markus Kreßmann, Partner at HTGF: “Sdui is systematically building its position as the No. 1 in the European EdTech market. This substantial round of financing will enable it to continue on this path. We are delighted to be part of this success story. When we invested in the seed round in 2019, we placed our trust in a founder who had only recently left school. Today, Sdui has grown to become one of Europe’s leading providers, employing over 230 people. It is a powerful example of what can be achieved when vision, entrepreneurial talent, and genuine demand come together.”

Maurice Kügler, Senior Investment Manager at HTGF: “It’s been incredible to witness Daniel and the team’s journey since we initially partnered back in 2019. We’re thrilled to keep backing Sdui as they take the next big leap forward!”
