Sponsor the Undiagnosed Hackathon
The Undiagnosed Hackathon is not a conference. It is an intensive, hands-on diagnostic event where clinicians, scientists, geneticists, bioinformaticians, and data specialists from all over the world sit side by side — no hierarchy, no silos — and work on real, unsolved cases. The families themselves, People Living With Undiagnosed Diseases, attend in person. Their presence transforms the work: as every dataset represents a family hoping for an answer.
Using the latest multiomic technologies — long-read genome sequencing, methylation, short- and long-read RNA, proteomics — combined with AI-assisted interpretation, the teams push beyond what routine diagnostics can achieve. All potential diagnoses are validated by clinicians before any clinical use, as part of a formal research protocol.
Since the first Undiagnosed Hackathon at Karolinska in Stockholm in 2023 — where around 100 experts from 28 countries found diagnoses for 40% of the participating families — the Undiagnosed Hackathon has travelled the world: Radboudumc in the Netherlands in 2024, in collaboration with Mayo Clinic in the USA in 2025, and with AVPN, CDFD and Sir Ganga Ram Hospital in India in 2026. The results of the first Hackathon were published in Nature Genetics, and each event since has delivered new diagnoses, new research leads, and new international collaborations.
In September 2026, the fifth Undiagnosed Hackathon takes place in Singapore, in collaboration with KK Women's and Children's Hospital, and planning is already underway for 2027 and beyond.
The Undiagnosed Hackathon is free of charge for the families and for the collaborating experts. That is only possible thanks to our sponsors. Your support helps cover what makes the Undiagnosed Hackathon work: sequencing and analysis, venues and meals, and the shared dinners where trust and lifelong collaborations are built.
As a major sponsor, you become part of the Hackathon itself. Sponsoring companies can bring additional colleagues beyond individually accepted participants, and can bring and demonstrate their tools during the event — working on real cases, alongside the world's leading experts, where the impact of your technology is immediately visible.
You will be recognized as a partner in an initiative that is changing how the world approaches undiagnosed diseases.

Sponsor Undiagnosed Day — 29 April
Undiagnosed Day, initiated and founded by Wilhelm Foundation, is observed every year on 29 April. It brings the worldwide undiagnosed community together in solidarity, collaboration, awareness, action, and hope. Our message to every family is simple: you are not alone. Our mission for the world is just as simple: to make the invisible visible.
Each year, Undiagnosed Day pairs a closed phenotyping round table for families from the region with an open meeting for the wider community — turning a moment of awareness into lasting momentum. In 2026, Undiagnosed Day was held in Gdańsk, Poland, in collaboration with ERDERA, the Medical University of Gdańsk, and UCK. In 2027, we take Undiagnosed Day to Belgrade. This isn't just a day — it's a movement, and sponsors carry it forward: your support enables families to take part, brings experts and families into the same room, and amplifies the voice of PLWUD around the world.

Families at the Center
Everything Wilhelm Foundation does begins and ends with the families. Alongside the Undiagnosed Hackathon and Undiagnosed Day, we run an annual Family Camp and a parent school on undiagnosed diseases, giving parents knowledge, community, and the reassurance that they are not alone on the diagnostic odyssey. Sponsorship of Wilhelm Foundation reaches all of this — one Wilhelm Foundation ecosystem, with the families at its heart.
Join Us
We would love to talk with you about how your company/organization can be part of this work — as a sponsor of the Undiagnosed Hackathon, of Undiagnosed Day, or of Wilhelm Foundation's mission as a whole.
Together, we can find new ways to solve the undiagnosed diseases that cannot be solved today, and give families the answer that changes everything.
