In the dynamic world of tech and investment, innovation in healthcare is constantly pushing boundaries. A prime example is the significant funding round recently closed by Craif, a Japanese Biotech Startup focused on revolutionizing Early Cancer Detection . This news highlights the continued interest in medical technology that promises non-invasive and more accessible diagnostic tools. Revolutionizing Detection: What Technology Does Craif Use? Cancer remains a major global health challenge. Traditional detection methods can be invasive or difficult to access for many people. Craif, a startup spun off from Nagoya University in 2018, is tackling this by developing an AI in Healthcare solution using microRNA (miRNA) biomarkers found in urine. Here’s a look at Craif’s approach: Biomarker Choice: Instead of commonly used cell-free DNA (cfDNA), Craif focuses on miRNA. miRNA is actively secreted by early cancer cells and is deeply involved in cancer biology, making it potentially suitable for detecting cancer at very early stages. Sample Type: The technology uses urine, which is non-invasive and easy to collect at home. This removes barriers associated with blood tests or clinic visits. AI Power: An AI-powered software analyzes the urinary miRNA patterns to identify the risk of specific cancers. This unique combination of miRNA and urine provides scientific advantages, such as fewer impurities in samples compared to blood, leading to clearer biomarker signals and potentially reduced measurement errors. Craif Funding: Fuelling Expansion and R&D Craif recently announced the completion of its Series C funding round, raising $22 million. This latest infusion brings the company’s total funding to $57 million. The round was led by existing investor X&KSK and included participation from new investors like U.S.-based Unreasonable Group (marking their first investment in a Japanese startup), TAUNS Laboratories, Daiwa House Industry, and Aozora Bank Group. CEO Ryuichi Onose stated the Series C round was completed at a valuation just under $100 million. This substantial Craif Funding is earmarked for two primary goals: expanding into the U.S. market and strengthening the company’s research and development efforts. From Personal Inspiration to Global Ambition The journey of Craif is deeply personal for co-founder and CEO Ryuichi Onose, whose family’s experience with cancer inspired his commitment to finding better detection methods. He co-founded Craif with Takao Yasui, an associate professor at Nagoya University, who had developed the initial method using urinary biomarkers. Their first product, miSignal, is already generating revenue in Japan. miSignal detects the risk of seven cancers (pancreatic, colorectal, lung, stomach, esophagus, breast, ovarian) using urinary miRNA. The product is distributed through clinics, pharmacies, direct-to-consumer sales, and corporate wellness programs, creating multiple revenue streams. Craif is partnered with over 1000 medical institutions and 600 pharmacies in Japan, serving approximately 20,000 users. The company reported $5 million in revenue in 2024 and aims for $15 million by the end of the year. Their revenue model includes both single tests and subscription plans, with many users opting for the convenience of subscriptions. Entering the U.S. Market: The Next Frontier for Medical Technology With its R&D lab already in Irvine, California, Craif is setting its sights firmly on the U.S. market. The company plans to open an additional office in San Diego to manage its U.S. business operations. The goal is to bring the miSignal test to the U.S., with trials expected to conclude by the end of 2026 and FDA approval potentially secured as early as 2027. Preparation is already underway, with Craif collecting pancreatic cancer samples in collaboration with 30 medical institutions across 15 U.S. states. This strategic move into one of the world’s largest healthcare markets is a significant step for the Medical Technology firm. Beyond cancer, Craif is also exploring the potential of its technology for detecting non-cancerous diseases, such as neurodegenerative disorders like dementia, indicating a broader vision for its platform. Facing Competition in Early Cancer Detection Craif operates in a competitive landscape with other startups also focused on Early Cancer Detection , including companies like Grail, Freenome, DELFI Diagnostics, and Clearnote Health. However, Craif believes its unique approach using miRNA and urine provides a strong differentiator in the market. In conclusion, Craif’s successful $22 million funding round underscores the growing investment and innovation in non-invasive Early Cancer Detection . By leveraging miRNA and urine with AI in Healthcare , the Biotech Startup is positioned to make cancer screening more accessible and effective globally. The significant Craif Funding provides the necessary resources to pursue U.S. market entry and continue advancing this promising Medical Technology .
