We build AI that institutions can explain, trust, and act on.
24may is an early-stage Causal AI company in Hong Kong. We put domain experts — not black boxes — at the centre of every decision.
Our story
24may started from a simple conviction: institutions do not just need to predict the future — they need to understand what causes it, so they can change it.
Standard machine learning is everywhere, and it is good at spotting patterns. But when a university, a government office, or an engineering firm has to justify a decision, correlation is not enough. They need cause.
We are early, and we treat that as an advantage: our first partners help shape the platform around real institutional problems, with their experts in the loop from day one.
Mission
What we do today
Make causal inference usable for institutions — turning expert knowledge into rigorous, explainable estimates of cause and effect.
Vision
Where we are heading
A future where every major institutional decision can be traced to cause — and defended — with humans firmly in the loop.
What we value
Core values
Explainability
Every result is auditable. If a committee can’t follow it, it isn’t finished.
Institutional Trust
We build for organisations that must justify decisions to stakeholders.
Hong Kong Roots
Grounded in HK’s institutions and its 18 districts, built to expand.
Honest Progress
We are early-stage and say so. No overclaiming, ever.
Education First
Technology that serves teaching, learning, and research.
