A new class of healthcare technology

We create mobile behavior change programs that help people achieve their goals, one healthy habit at a time.

As a startup founded by clinicians, we’ve seen first hand how the smallest changes in behaviour can lead to a profound impact on health outcomes. Yet high quality and evidence-based behavioural therapy remains difficult to access for the majority of the world.

Our mission is to change that by making evidence-based and cost-effective behavioural therapy available to everyone, everywhere.

What is ‘Digital

(di-gi-tal ther-ah-peu-tics)
— noun

Digital therapeutics is the simple idea that digital behavioural change programmes can be as, if not more, effective at preventing and treating chronic disease than pills and potions.

Digital therapeutics is not simply data visualisation. It is about structured behaviour change utilising big data, evidence-based therapies and user-centered design.

Like all medical therapies, digital therapeutics must pass the bar of being clinically validated in rigorously designed and peer-reviewed studies.

Quit Genius

Our first product - a new way to quit smoking. It’s not magic, it’s just really good science.

Quit Genius is the product of more than two years of research working with smokers, scientists, psychologists and doctors. Despite 70% of the 1 billion smokers globally looking to quit, just 3% are successful, due to the lack of access to behavioural support.

See how it works

The Quit Genius journey delivers cognitive behavioural therapy (CBT) in bite-sized steps consisting of animated videos, audio sessions and interactive exercises.

Our trained Quit Smoking Coaches analyse a user’s smoking patterns, sharing personalised tips to help users overcome their triggers.

The feedback loop is completed with gamified challenges, achievements and a vibrant in-app support network.

  • 36% Smoking cessation rate
  • 60% Fewer cigarettes smoked
  • 260K Life-years gained
  • $155M Savings to employers
