David Deems, CEO

Mr. Deems is a senior executive with a proven ability to commercialize and successfully launch novel technology products for the life sciences and diagnostic markets. During his career, he has developed and launched over 100 new products, in regulated and research markets, and for large public and small venture-backed companies. Most recently, Mr. Deems was the President and CEO of Xceed Molecular (now part of Axela), a Canadian company with a novel gene expression platform used by clinical laboratories for testing novel biomarkers.

He joined Xceed from Predicant Biosciences, an early-stage proteomics company working to identify protein patterns in blood for the early detection of cancer, where he was responsible for managing Predicant’s product and commercial development efforts. Prior to Predicant, David held senior management positions with several companies focused on bringing novel products successfully into the marketplace. He served as Vice President of Product Development at EXACT Sciences; CEO of Union Biometrica prior to that company’s acquisition by Harvard Biosciences; and Vice President at BD Biosciences, a division of Becton, Dickinson and Company.
