About
Signal 1 is a health AI startup with the mission to transform patient care through responsibly deployed AI. Founded in April 2022 and headquartered in Toronto, Canada, Signal 1 provides hospitals with an end-to-end AI Management Platform (AIMS) that helps health systems accelerate AI adoption while managing risk across their growing AI portfolios. The company emerged from a collaboration with Unity Health Toronto and leverages AI technology originally developed by TD Bank's Layer 6 team. Signal 1's platform offers comprehensive oversight of predictive, generative, and agentic AI applications, introducing governance workflows and guardrails to mitigate downside risks. Their first clinical application, CHARTWatch, is a real-time patient risk predictor that accurately forecasts which hospital patients are likely to deteriorate, enabling earlier interventions and improved patient outcomes. Trusted by leading North American healthcare organizations including Trillium Health Partners, Inova, and Unity Health Toronto, Signal 1 is setting the standard for responsible AI deployment in healthcare, helping translate innovation into real clinical, operational, and financial outcomes.
