We have developed the only digital method of birth control cleared by regulators both in the US and in Europe. Effective, natural, and backed by clinical research - Natural Cycles has been cleared by the US FDA and CE marked in Europe. Today we have a growing user base, who are happy to have found a method of birth control that is right for them and that allows them to get to know their bodies and cycles. No matter what your choice is, we believe that every woman should know that understanding how your cycle works matters. Natural Cycles was created when our founders, Elina and Raoul, were in search of an effective method of natural birth control. Their journey took them from physics straight into health tech for women. The couple were unsatisfied with what they found, so they decided to apply their experience and knowledge in advanced mathematics and data analysis to develop a solution to meet their needs. This turned out to be an algorithm that detects and predicts ovulation and fertility. In the early days, they used the algorithm for their own purposes but quickly realized that there was a vast unmet need for this type of method. They decided to develop a mobile app so women from all over the world could easily access and use Natural Cycles. Our company has been up and running since 2013 and has been rapidly growing since our CE certification in February 2017. At Natural Cycles we are always looking for passionate talents to help us strive for change in such a complex, scientific, and controversial field. We have womens best interest at heart and work hard every single day to ensure that we provide the best possible solution. That’s why each and every team member is passionate about what we do. Gathered from all corners of the world we are a tight-knit international team located right in the center of beautiful Stockholm.

Awarded for “most innovative German startup” from German business magazine Bilanz, DiaMonTech has developed a medical device that non-invasively measures your blood glucose without finger pricking, a drop of blood, or a test strip. Simply relax your fingertip on the sensor, wait 5 to 15 seconds, and your blood glucose level will be displayed. Our patented technology works with an invisible infrared light beam that looks into your skin and counts glucose molecules. Diabetes is a global challenge. More than 400 million people worldwide suffer from the disease. Our goal is to make checking your blood glucose level as easy as unlocking your phone. You will be able to get measurements throughout the day without pain or extra costs. Diabetologists suggest that more frequent blood glucose measurements can lead to better overall diabetes management and less diabetes-related illnesses. Until there’s a cure for diabetes, DiaMonTech can make living with it much easier.
