Impiricus

Impiricus operates an AI-powered HCP Engagement Engine, a platform that connects healthcare professionals with pharmaceutical resources through real-time channels. The system uses AI and real-time messaging to deliver evidence-based pharmaceutical material directly to physicians, in particular those who are not reached through conventional engagement routes. The company works across the pharmaceutical, healthcare, life-sciences and digital-health sectors in North America.

The platform's stated reach is substantial. Impiricus says it holds the largest opted-in network of healthcare providers, and that it reaches roughly 30% of physicians who do not engage through traditional channels. Ninety-five per cent of messages are opened within three minutes. The company reports that its work helped 1m patients access therapy in 2025, and it ranked first on Deloitte's 2025 Technology Fast 500 as the fastest-growing company in North America.

Technical work at Impiricus spans AI and machine learning, real-time messaging and engagement platforms, healthcare technology and pharmaceutical communications. Roles touch both the modelling side of the engagement engine and the delivery infrastructure behind high-velocity, high-open-rate messaging at scale.

The company was founded out of frustration with how healthcare professionals connect with pharmaceutical firms. Its co-founders are a board-certified dermatologist and a healthcare executive, and the stated focus of the business is physician and patient outcomes rather than industry recognition.
