- Student and teacher data stays in the EU.

What Klario handles
One system instead of five
Timetable and planning
Lessons, rooms and teachers in one place. Change a lesson and availability, invoicing and messages follow.
Enrolment and students
A new student signs up online and everything follows: timetable, contract and invoicing. No retyping.
Contracts and compliance
Teacher contracts based on the Klario model, designed to prevent false self-employment.
Invoicing and direct debit
Invoices, iDEAL, SEPA direct debit and reminders run automatically. No more calls about money.
Messaging
Messages to students, parents and teachers from the same system. Everyone knows where they stand.
Dashboards
The numbers that give you control: finance, planning and occupancy. For you and for your teachers.
One location or many
Whether you run one school or ten. You grow without your admin growing with you.
Teacher workspace
Teachers see their timetable, students and own numbers. Each runs their own practice, inside your school.
Knowledge base
Your agreements, ways of working and policies in one place. So nothing lives in one person's head.
How Klario uses AI
AI before and after execution, never in between
This is how it is designed: you run your school in plain language. Say "move all of this teacher's Tuesday lessons to Wednesday". The AI turns that into a proposal. You approve it, and a fixed, predictable engine carries it out. The AI never touches the numbers.
And the system learns. When the AI keeps proposing the same routine, it asks whether that routine can become permanent. With your approval it then runs without AI. The more you use it, the less AI it needs.
- Klario’s AI is powered by Mistral, a European AI provider.
- Hosted in the EU, without the model provider storing your data.
- Every action can be traced and checked.
Built in the Netherlands
Made for the Dutch market first
A lot of school software comes from the US, or is fitness software with a music layer. Klario was built inside a Dutch music school, around Dutch rules.
Payments via Mollie
iDEAL, SEPA direct debit, credit card, Klarna and more. Students pay the way that suits them.
Built around Dutch law
False self-employment and the Dutch tax authority's rules were part of the design from day one.
From the sector itself
Made in a real music school. Not by a software company serving six industries at once.
