What is Jaisy

We have developed a low cost but highly accurate solution for non-invasive jaundice (sv. gulsot) detection and measurement, with the ability to be widely spread and used by any clinic in the world and also affordable by any rural community and private individuals.


Current jaundice meters optically measure the bilirubin level using highly expensive spectrometer sensors. The major brands are very expensive as the cost per unit is around $10.000 or more. We are working for an affordable device.


Jaundice today is mainly diagnosed by invasive methods such as blood analysis, which is associated with the risk of infection, causes discomfort and pain, and also relies on certain clinical expertise. Jaisy is a non-invasive device.

User friendly

We are evaluating the opportunity in selling our device and end-user application directly to parents, through pharmacies or online, who want to perform the jaundice test at home on their own.

We are one the finalists in the Swedbank Rivstart competition.
