Natural Cycles is a women’s health company pioneering research-driven, non-hormonal contraceptive solutions. Our flagship product is the world’s first FDA-cleared birth control app that analyzes body temperature and cycle data with a clinically-tested algorithm to help users plan or prevent pregnancy.

Founded by particle physicist Elina Berglund, the company grew from a scientific curiosity into a regulated medical solution backed by peer-reviewed research. Natural Cycles emphasizes safety, transparency and evidence-based development — collaborating with academics, clinicians, and data scientists to continually improve the product.

Key facts: founded in 2013, 4 million registered users, 22 published journal papers, 13 million+ cycles analyzed, and ~140 employees with offices in Stockholm, Genève and New York (remote-first culture).

We combine medical research, algorithm development and user-centred product design to offer a natural, non-invasive alternative to hormonal contraception. The app is CE certified and FDA cleared for contraception and has additional clearances to integrate temperature data from wearable devices.

Natural Cycles also runs an in-house Medical, Algorithm and Data team driving clinical studies and publications to advance female health research. Our mission is to empower users with knowledge and tools to make informed decisions about their reproductive health.

Natural Cycles is a fast-growing, international company with a diverse team representing 30+ nationalities. Benefits include remote-first work, parental leave, wellness allowance, flexible holidays, childcare support and regular team retreats.
