That is the world we are building toward. Josie is a comprehensive digital health platform for the 1 in 8 women living with PMOS, giving them the tools to understand their condition, advocate for themselves in medical settings, and navigate a care system that was not built for them.
Why Josie exists
“Josie exists because we lived this. And because we believe it can be better.”
1 in 8
PMOS affects around 1 in 8 women of reproductive age, making it one of the most common hormonal conditions in the world.
Once diagnosed, care is fragmented. Gynaecologists, endocrinologists, dermatologists, nutritionists, and mental health professionals all play a role, but no system connects them. Women are left to coordinate their own care, track their own symptoms, and advocate for themselves in a system that routinely underestimates the complexity of their condition.
Existing digital tools do not solve this. Period trackers assume regular cycles. Nutrition apps push one-size-fits-all diets. None of them address the full metabolic, reproductive, and psychological picture of PMOS, and none of them help women prepare for the medical appointments that actually determine their care.
What we stand for
Four promises we hold ourselves to, and that you can check us on.
Every article in the app is reviewed by a clinician before it is published, and reviewed again when the guidelines change.
Stored in the EU, encrypted in transit and at rest, exportable or deletable at any time. We never sell it.
Both founders live with PMOS. Every feature starts from something we needed ourselves and could not find.
Josie is a tracking and preparation tool, not a diagnosis. We say that plainly, everywhere it matters.
Lived experience, clinical rigour, and a shared conviction that PMOS care has to get better.
Co-Founder
Laure was diagnosed with PMOS after years of dismissed symptoms and fragmented care. That experience, combined with her background in strategy consulting at EY, an MBA from UCLouvain, and an Advanced Master in Biotech and Medtech Ventures from Solvay Business School, drove her to build the tool she wished she had.
At Josie, Laure leads technical development, strategy, regulatory affairs, and fundraising.
Co-Founder
Manon knows firsthand how isolating a PMOS diagnosis can feel. That experience, combined with her background in international sales at La Collection, an MBA in Business Administration and Management from Vrije Universiteit Brussel, and a passion for design, drove her to build an app that makes women with PMOS feel seen, prepared, and in control.
At Josie, Manon leads design, UX, business development, and content creation.
Our scientific board
Our scientific advisory board reviews Josie's health content for clinical accuracy, dosing guidance and alignment with current PMOS research and clinical guidelines. Each article on this site shows its review status.
Board composition includes specialists in gynaecology, endocrinology, and nutrition with PMOS expertise. Board members are listed here as they are formally announced.
Our mission
Our mission is to give women with PMOS the tools to understand their condition, the data to advocate in medical settings, and the support to navigate fragmented care.
In the app today
Intelligent symptom tracking, pattern recognition, doctor-specific appointment preparation, and evidence-based education that closes the information gap between women and the system that is supposed to serve them.
Structured appointment prep reports, longitudinal data exports, and interoperability-ready data make it easy for healthcare providers to see the full picture of a patient's PMOS experience across specialists.
What we are working toward
Clinical evidence demonstrating measurable health outcomes positions Josie for reimbursement conversations with public and private insurers across Europe.
We are pursuing structured reimbursement pathways in Belgium, France, and Germany so that access to PMOS management tools is covered by public health insurance, not just available to those who can afford a subscription.
Hospital partnerships, healthcare system connectivity, and longitudinal data create a PMOS management ecosystem where women, doctors, and insurers are aligned.
