About Nabla

We are a team of entrepreneurs, clinicians and engineers committed to bringing back joy to the practice of medicine. Together with a community of clinician innovators, we’ve harnessed the best of machine learning science to develop Nabla: the leading AI assistant that’s restoring the human connection at the heart of healthcare. By streamlining clinical documentation, Nabla is helping clinicians focus on what matters most—patient care. Today, over 100,000 clinicians across more than 130 healthcare organizations trust Nabla to support how they deliver care every day.

We’re at the start of an ambitious journey: ambient listening, dictation, coding, and command capabilities are all converging into a proactive assistant that intuitively streamlines clinical and financial workflows. Backed by a recent $70 M Series C, we’re hiring to build the next generation of clinical AI and improve the lives of clinicians and patients everywhere.
