About Altis Labs

Altis Labs is the computational imaging company advancing precision medicine with AI. We believe that medical imaging is the richest data modality to generate clinical insight. Scientists use our AI-powered software platform, Nota, to accelerate clinical research by more accurately measuring the effect of novel treatments. Trained on over 222 million images with associated clinical information, our deep learning models hosted on Nota predict clinically meaningful outcomes. Legacy data interpretation methods have confined scientists to slow, risky, and expensive drug development requiring more than $2 billion and 10 years to get a new treatment to patients in need.

Our multi-disciplinary team of data scientists, engineers, clinicians, and business operators is on a mission to help get the most effective treatment to patients sooner.

Founded in 2019, Altis is a venture-backed company headquartered in Toronto. We are actively growing our team in Canada and the US across functional areas.
