Replacing the stethoscope.

We want to revolutionise screening for disease with novel medical devices and machine learning. Our goal is to transform lives by providing early detection of disease to everyone.

The stethoscope is an outdated tool.

Abnormal sounds are the first warning sign for many diseases in the heart, lungs and other organs. For the past 200 years medicine has relied on a doctor using a stethoscope to interpret the sounds and produce a diagnosis.

This is time-consuming and inaccurate. Diagnoses are being missed and healthcare is being overburdened.

We want to change this.

Valvular heart disease is the next cardiac epidemic.

Heart valve disease is the most common heart disease detected with a stethoscope.

Nearly two million people in the UK have significant valvular heart disease. Less than half of them are diagnosed. As our population ages, the burden will double by 2050.

By the time severe symptoms present, patients die within two to five years.

We need a new solution to prevent life-limiting symptoms and sudden cardiac death.

Our solution

A simple, accessible screening tool for valvular heart disease.


Novel acoustic hardware

A novel medical device that replaces the stethoscope in recording sounds from the body. Not just a tool for doctors but designed to be accessible to any healthcare professional.


AI-driven diagnoses

By using state-of-the-art machine learning techniques, we can automatically analyse sound recordings to predict the presence of clinically significant disease accurately. Our software completely removes the skill barrier to interpreting the sounds heard while providing greater accuracy than a GP with many years of experience.

Our models are trained and evaluated on our world-leading datasets consisting of thousands of recordings from actual NHS patients with valvular heart disease.

About us

We are a spin-out from the University of Cambridge Acoustics Lab. We are a team of engineers, machine learning experts and experienced clinicians who are all passionate about transforming patient lives by improving early detection of disease across the world.
