About
A consultancy built around delivery
Horizon Health Economics is a consultancy focused on health economic modelling and healthcare data analytics. We are a small, agile team of technical experts focused on delivering impact through health economics.
Accountable
The experts that design your projects also deliver them, ensuring accountability, consistency, and quality at every stage.
Focused
We tailor our approach to each project’s unique challenges, opportunities and target audience.
Philosophy
Models that earn their keep
“All models are wrong, but some are useful.” — George E. P. Box
Every model simplifies the representation of reality, but the true value of each modelling application lies in how it helps us understand and inform real-world decisions.
We build models that reveal key relationships and value insights, that make the best use of available data, and that help clarify and quantify uncertainty. By focusing on practical insight over abstraction we help our clients act with confidence in complex evidence generation landscapes.
We design our models to communicate with maximum impact and clarity, ensuring deliverables are always tailored to the target audience.
