The Globe and Mail reports in its Monday edition that Tomi Poutanen and Mara Lederman left high-profile jobs in 2022 to create artificial intelligence tools for hospitals. The Globe's Sean Silcoff writes that their start-up, Signal 1 AI Inc., developed four applications, such as predictive models identified which patients were at the highest risk and needed immediate intervention. Several Canadian hospitals signed up, but prospective clients kept saying the same thing: Signal 1 was competing in a busy market that included electronic medical records giants, vibe-coding start-ups and hospitals building tools themselves. What the hospitals said they really needed was an application to oversee and monitor all those AI programs. Fortunately, Toronto-based Signal 1 already had such a tool, which it used to support its own suite of applications. So, in 2025, Signal 1 went all in on commercializing its AI management system (AIMS), emulating seminal pivots by Shopify and Slack to focus on selling infrastructure tools they had developed to support their original businesses. The shift has paid off. On Monday, Mount Sinai, which has seven hospitals and three schools in New York, announced it is adopting Signal 1's AIMS platform.
