AIM Rule 26

Diaceutics is the intelligence and engagement company unlocking the full potential of diagnostic-driven therapies.

We work at the intersection of data, science and commercial strategy, helping biopharma companies identify eligible patients earlier, understand where diagnostic pathways break down and act while treatment decisions are still forming.

Our vision is Precision for All: a future where every eligible patient is identified, diagnosed and receives the right therapy at precisely the right time.

The Company’s solutions support biopharma teams as they commercialize therapies that depend on timely testing, clearer pathway intelligence and more precise engagement across the treatment journey.

The Company was incorporated and registered in Northern Ireland with registered number NI055207. Its main country of operation is Northern Ireland with wholly owned subsidiary undertakings in Northern Ireland, the Republic of Ireland, the US and Singapore.
