Brook.ai combines intelligent data collection, AI-driven insights, and remote clinical teams to extend care into patients’ homes without adding to clinician workloads. Its platform has demonstrated tangible clinical improvements, including a 90% reduction in congestive heart failure readmissions and an 80% rise in controlled hypertension populations within six weeks. High engagement underpins these outcomes, reflected in an 82% patient retention rate, a Net Promoter Score of 66, and 204% year-over-year patient growth. Brook’s personal health assistant—part AI, part nurse—has been trained on millions of patient conversations, delivering timely nudges and recommendations that bolster patient satisfaction and provider ROI. Revenue figures were not disclosed, but the company’s strong operating metrics and expanding customer base signal healthy traction. With fresh capital, Brook plans to enlarge its product and engineering teams (with an emphasis on safe AI), enhance product features to deepen engagement, broaden coverage to additional conditions, and scale operations nationwide. Ultimately, Brook.ai aims to make remote, proactive care a standard component of U.S. healthcare.
