Our Mission:
Transforming Cancer Detection
Every year, more than 18 million people are diagnosed with cancer and 9.6 million people from it. At Rarecells, we are committed to changing this outcome through disruptive innovation in early cancer detection.
Our mission is to make ultra-early blood-based detectipn of cancer a clinical and global reality — turning today’s late diagnosis into tomorrow’s preventions.
The Challenge: Detecting Cancer Before It Grows
Cancer evolves continuously, creating heterogeneous populations of tumor cells that adapt and resist therapy. By the time a tumor becomes detectable through imaging, it already contains millions of malignant cells.
At that stage, even the most advanced therapies struggle to eradicate the disease completely. This is why early detection is not just an advantage – it is the decisive factor in survival.
Our Solution:
The ISET® Platform
Rarecells has pioneered the ISET® (Isolation by Size Epithelial Tumor Cells) platform — a hypersensitive liquid biopsy technology that isolates and identifies circulating tumor cells (CTCs) directly from blood, without any marker bias.
With unparalleled sensitivity and specificity, ISET® is the only clinically proven method capable of detecting cancer years before imaging, enabling earlier intervention and dramatically improving patient outcomes.
This technology is the result of two decades of scientific excellence, peer-reviewed validation and clinical collaborations worldwide.
A New Era in Liquid Biopsy
Our R&D pipeline focuses on integrating cellular and molecular readouts, and combining CTC-DNA, ctDNA, and multiomic analysis powered by AI.
By merging the power of cell biology and artificial intelligence, Rarecells is advancing toward a new standard is precision oncology, where cancer can be tracked, characterized, and eliminated from its earliest stages.
We are now scaling our platform for broad clinical deployment, in partnership with academic centers, biotech innovators, and healthcare systems.
The Vision Ahead
The convergence of molecular science, data analytics, and AI-driven interpretation makes it possible —today— to detect cancer before it becomes visible.
Our goal is to make this capability accessible to millions, changing the way cancer is diagnosed, treated, and ultimately prevented.
At Rarecells, we invite investors and partners to join us in accelerating the global adoption of early cancer detection.
Together, we can make cancer defeat possible — from its start.

Prof Paterlini oversees the continuing development of Rarecells and its ISET® technology. Her work was acknowledged by 13 prestigious awards and led to 49+ granted patents and 90+ high level scientific publications.
Dr Neil Gunn PhD
Recognized industry expert, Dr Gunn has spent 12 years at Roche Diagnostics, where he led the launches of well over one hundred products. He was also responsible for building Roche’s sequencing business, demonstrating above market performance and growing the team by more than 500 percent. Previously, Gunn spent eight years at Chiron Blood Testing, where he introduced the first molecular tests for blood screening (HIV and HCV) that are now standard practice around the world. More recently Dr Gunn has served as CEO of infectious disease company IDbyDNA, to its acquisition by Illumina.
Neil Kurtz MD
Successful serial entrepreneur, physician, and Board-certified psychiatrist Neil Kurtz graduated from medical school in Wisconsin and is licensed to practice medicine in California. Neil served as Assistant Professor at the Department of Psychiatry at the University of California – Los Angeles before gaining 30 years of experience in the healthcare and pharmaceutical industry, including serving as worldwide head of R&D for Boots Pharmaceuticals, launching a Clinical Research Organization that was sold to UnitedHealth Group, and serving as CEO of Golden Living, one of the largest diversified providers of post-acute care. Dr. Kurtz has consulted for more than 70 investment groups and served as founding board member and chair for Medidata until its sale to Dassault Systemes for $5.8 billion.
Prof Christian Brechot MD, PhD
After working as a researcher in the field of virology, Christian Bréchot was president and general manager of INSERM (Institut National de Santé et Recherche Médicale), the largest scientific health institution in France. He was then appointed as Vice-President of Medical and Scientific Affairs of the Institut Merieux company. From October 2013- to September 2017 he served as President of the Institut Pasteur, Paris, France.
Dr. Brechot is currently the Senior Associate Dean for Research in Global Affairs and the Associate Vice-President for International Partnerships and Innovation at the University of South Florida, Tampa, USA. Additionally, he is currently the President of the Global Virus Network, Baltimore, USA.
