After years of research and clinical testing, we have developed non-invasive, accurate blood tests for early detection of cancer. By making cancer prevention routine, we enable everyone to take control of their own health. The more people take our breakthrough blood tests, the more lives we can save. Life over cancer.


Our Expertise

To achieve our mission of transforming how cancer is diagnosed and managed with globally affordable non-invasive tests for early cancer detection and management, we have built a team of experts across multiple disciplines, including circulating tumor cells, semiconductors, next generation sequencing, precision medicine, oncology and immunology.

Atul Sharan

Chief Executive Officer

In 2012, as an Entrepreneur in Residence at a leading Silicon Valley Venture Firm, Artiman Ventures, Atul Sharan co-founded CellMax Life, applying semiconductor industry principles to a proprietary Circulating Tumor Cell (CTC) bio-mimetic CMx platform to develop affordable, clinically proven blood-tests for Early Cancer Detection and Treatment. He was motivated to start CellMax as two members of his family have been diagnosed with cancer – one of them was diagnosed with breast cancer within two weeks of receiving a conclusively negative mammogram. Atul is a veteran of the high-tech industry with experience as an engineer, serial entrepreneur, CEO and angel investor. He specializes in identifying unmet market needs and matching them with early-stage technologies to achieve dramatically better results than prevailing standards. He has done that successfully multiple times: AutoESL (acquired by Xilinx); ClearShape Technologies (acquired by Cadence), Numerical Technologies (Nasdaq IPO; acquired by Synopsys); Ambit Design (acquired by Cadence). Atul holds a BS in Engineering from IIT-India; MS in Engineering from UH, Texas and an MBA from UC-Berkeley.
