Yosef’s Story

No one could work out why his heart was racing. He spent 12 months in and out of the hospital with 3 different cardiac monitoring devices. Eventually, he was diagnosed with Atrial Fibrillation and underwent treatment that has since stabilised his condition and helped him return to normal family life.

Diagnosing cardiac arrhythmia can be like finding a needle in a haystack. Episodes often happen outside the time of prescribed specialist heart monitors.

Another challenge is getting specialist heart monitors for patients in remote places. It can be difficult and expensive, leaving millions of people worldwide with cardiovascular disease undetected until it is too late.

Heart disease is the world’s single biggest killer. Yet 80% of it is preventable.

Having witnessed my father’s distress, and the impact it had on all of our family, I wanted to use my expertise in engineering and AI to change all of this.

We have developed an innovative technology using just photoplethysmography (PPG) and a smartphone to lead the way toward a healthier heart for everyone, anywhere, at any time.

We spent 6 years in clinical studies and regulatory approvals.

The result is our company – Happitech.

We have successfully redefined the way atrial fibrillation can be screened and monitored.

Happitech aims to provide accessible, low cost ways of monitoring patients using everyday devices.

With healthcare costs ever-increasing health insurers are demanding that all stakeholders  provide solutions at lower costs for the same quality of care.

Telehealth companies have stepped in to reduce costs by monitoring patients outside of the hospital. There is an increasing need for low-cost, rapidly scalable, connected devices to monitor thousands of patients in their homes.

Developed by the experts at

Aerospace, Communication, Computer vision engineers brought to the Medical world.

Based in Amsterdam and founded in 2015, our dedicated team helps us in reaching our goal to support over 10 million heart patients worldwide. Without the Happitech family, none of the amazing work we do would be possible.
