LinkedIn ↗Not a startup that went looking for a problem. A school problem that needed a real engine, built where the problem was, and still running there every term.

Most tools flatten every school onto one grid and leave the hard part to a person with a spreadsheet and three weeks of August: reconciling every student’s subject choices against every teacher’s availability, every room’s capacity and every curriculum’s minimum hours — all at once, for everyone, with no exceptions allowed.
Schedual runs a genuine constraint-satisfaction solver, the same class of engine used in industrial logistics. It does not draft something plausible for you to correct. It returns a week in which every hard rule holds simultaneously, or it tells you precisely which rule cannot be satisfied and why.
École Privée Bilingue Internationale, Geneva. Running the published week since 2025.
An international school in Geneva runs the IB Primary Years, Middle Years and Diploma programmes together — nine hundred and ten students sharing one set of teachers and rooms across three entirely different curricular models. Its timetable was built by hand every year. Every year it cost weeks, and every year it still produced clashes that only surfaced once students received their sheets.
We built the engine for that school first, and it has generated its live published week since 2025. Adding IGCSE, GCSE and A-Level, the French Baccalauréat and US high schools did not require a second product: the solver core is curriculum-agnostic, and each system is described to it as a pack — what its stages are, and how its students choose.
A French company. Student data sits on European infrastructure we control, with a signed data processing agreement available on request and a plain list of everything we hold.
