Synex

Synex Medical is a Toronto-based medical technology company developing non-invasive health monitoring devices to enable predictive and personalized medicine. Founded in 2017 by Ben Nashman, Synex uses magnetic resonance spectroscopy (MRS) to accurately measure blood metabolites — including glucose and lactate — without needles or skin penetration. The technology applies low-power radio frequency pulses to align and excite hydrogen protons in the fingertip, detecting and quantifying metabolite concentrations in real time. Synex's approach addresses what many researchers have called the 'Holy Grail' of health monitoring. The company has backing from Radical Ventures, Khosla Ventures, Accomplice, and Fundomo, and employs a team of scientists, engineers, and healthcare professionals from institutions including Columbia University, WHOOP, and Synaptive Medical.
