We build the civic infrastructure that shapes the rhythm of learning.
Behind every lecture, seminar, and tutorial sits an invisible hero: the university timetabler. These are the professionals who absorb constant change, navigate incomplete data, and balance competing demands, all so that students can simply show up and learn. Aion exists for them. Not to replace their judgement. To extend it. We build the systems that let timetablers think further ahead, act with greater confidence, and hand the whole institution a rhythm it can depend on — year after year, decade after decade.
Who We Are
Aion timetables education across the globe, bringing together two specialist brands with decades of combined expertise in one of higher education's most consequential, and most overlooked, problems. Built to last. Backed by Volaris Group, a forever-invested acquirer that has never sold a business; Aion invests in the long arc. No exit pressure. No debt. Just sustained commitment to the institutions we serve, and to the timetablers who hold them together.

Celcat
United Kingdom
Based in the UK, Celcat has worked alongside further and higher education institutions for over 30 years — across the UK, France, South Africa, and Australia - in English, in French. Thirty years of constraint-handling, institutional complexity, and schedulers who know they can call us. Over 200 universities. A re-imagined product for a new agentic age.
Bullet Solutions
Portugal
Based in Porto, Bullet Solutions was founded at the University of Porto and has spent twenty years solving the scheduling complexity of Iberian and Latin American higher education — in Portuguese, in Spanish, and with the institutional knowledge that only comes from being there. Over 100 universities. A constraint engine built for the real world re-imagined for a new agentic age.
A New Category
We are not an upgrade. We are not a bolt-on. We are a different kind of software entirely. New architecture for a new age - AI first.
The Old World
For decades, timetabling software did one thing: it scheduled using constraints limited by human decisions. It stored, read, viewed, updated records. It displayed conflicts. It waited. The timetabler carried the cognitive load of managing change — alone, every time, from scratch.
A New Architecture
We built Celcat AI differently. Not on top of the old model — outside of it. An AI-native graph database that holds every relationship in your institution simultaneously. A cohort of specialised AI agents that analyse, detect risk, and recommend — collaboratively, with reasoning you can see and trust.
A System of Action
Celcat AI doesn't wait to be told what to do. It reads your institution — rooms, staff, cohorts, constraints, policy — and works. It models scenarios before you commit to them. It adapts when things change. It thinks alongside your timetabler, so your timetabler can think further ahead.
Beyond Automation
Automation removes steps. We remove the ceiling. Others have made the old process faster. We have made a new process possible.
A New Category
This is what it looks like when thirty years of constraint-handling expertise meets agentic AI — built from the ground up, for an institution that can't afford to get timetabling wrong.
This is not a feature. This is not a product update.
This is a new category. And we built it first.
Not linear. Not finite. Aion.
Aion is a Hellenistic deity associated with time, not the linear, progressive time of clocks and calendars, but perpetual, cyclic, unbounded time. Where Chronos divides time into past, present, and future, Aion holds it whole.
The name is not a coincidence. Perpetual time reflects Volaris's commitment to hold forever, providing security for our customers and staff across decades, not cycles. Cyclic time aligns with our core purpose: timetabling education, the rhythm that never stops.
