About the founders
Natural Cycles began in 2013 when particle physicist Dr. Elina Berglund Scherwitzl sought a more natural way to manage her fertility. After removing her birth control implant, she wanted to prevent pregnancy in the short term with the goal of starting a family in the near future. When Elina couldn't find a reliable, non-hormonal birth control option, she decided to create it herself.
After contributing to the Nobel Prize-winning discovery of the Higgs Boson particle at CERN, Elina applied her research expertise to develop the Natural Cycles algorithm. By tracking body temperature, the tool gives women a data-driven way to understand their cycles and manage their fertility naturally. Today, Natural Cycles supports millions of women at every stage of their fertility journey — whether they are preventing pregnancy, trying to conceive, following a pregnancy, recovering from childbirth or a miscarriage, or navigating the hormonal shifts of perimenopause.
Together with her co-founder and husband, Raoul Scherwitzl, Elina continues to lead Natural Cycles in its mission to empower every woman with the knowledge she needs to take charge of her health.
