About Klario
Built by a school owner, for school owners
Klario didn't start in a software company. It started in a music school in Ede, the Netherlands, with an owner who got stuck in his own admin and built what he needed.
Our mission
Human connection is the heart of learning
Without it, we lose what makes us human. A teacher who sees you, challenges you and inspires you can't be replaced by technology. The more the world runs on AI, the more that human connection matters.
Klario uses technology to free teachers and schools from everything that isn't teaching. So musicians, dancers and other makers can keep doing what they're here for: inspiring people and helping them grow.
The founder
Collin Leijenaar
Internationally touring drummer and entrepreneur
Collin drums in international prog rock and metal bands, including Neal Morse, Dilemma, Affector and Kayak. He has also run Novae Popschool in Ede for over 28 years, with 300+ students a year.
For years he was director and administrator at the same time. Sixty to eighty hours a week, most of it admin. He built Klario to get out of that. A first version has been running at Novae since 2019, and his work week went down to half a day. Now he makes that possible for other music, dance and theatre schools.
What we stand for
How we work
From practice
Every feature is tested in a real school first. We build what schools need in practice.
Built on franchise law
School and teacher work together as two businesses, with clear roles. Designed to prevent false self-employment.
Data in Europe
Student and teacher data stays in the EU. Many students are minors. We handle that with care.
