Koblenz, Germany — July 2025
German startup Sdui Group, a fast-growing provider of cloud-based software for K–12 schools, has secured a significant growth investment led by Bain Capital’s Tech Opportunities fund, with continued support from existing backers HV Capital and High-Tech Gründerfonds (HTGF). The funding marks a major step in the company’s push to become the dominant digital infrastructure for education across Europe.
Founded in 2018, Sdui has quickly positioned itself as a trusted technology partner for thousands of schools across Germany, Austria, Switzerland, and Spain. Its platform centralizes key school operations — including communication, scheduling, attendance, and grading — into one intuitive system. The startup currently employs around 230 people and continues to grow across European markets.
With this new funding, Sdui plans to deepen its product capabilities, accelerate expansion into new regions, and further integrate regional education software players under a single, scalable ecosystem. The company’s goal: to become the “digital backbone” of European schools.
“Bain Capital brings more than just capital — they bring deep operational expertise and a strategic vision aligned with our mission,” said Daniel Zacharias, CEO and founder of Sdui Group. “With their backing, and continued trust from HV and HTGF, we’re better equipped than ever to simplify everyday school operations across Europe.”
The investment comes at a time when education systems across the continent are facing increasing pressure to modernize. From new digital mandates to evolving expectations from teachers and parents, schools are seeking comprehensive solutions that ease administrative burdens and give educators more time to focus on students.
“We see this as a moment of transformation in European education,” said James Stevens, Partner at Bain Capital. “Sdui has built a platform that truly meets the day-to-day needs of schools. We’re excited to support their next phase of growth.”
Backers like HV Capital and HTGF, who have supported Sdui since its early stages, say the company’s trajectory reflects a rare combination of market timing, technical execution, and founder drive.
“Sdui is on its way to becoming the No. 1 EdTech platform in Europe,” said Markus Kreßmann, Partner at HTGF. “We believed in Daniel’s vision when he had just left school himself. Today, he leads one of the continent’s most promising education companies.”
By building a unified platform that addresses the fragmented nature of school software, Sdui is emerging as a key player in Europe’s digital education future — one API, timetable, and push notification at a time.
