Iterative Health secured $77 million in a Series C round to expand its AI-enabled clinical trial enrollment services and scale operations across cardiology and obesity trials. The company said the funding will support global site partnerships, accelerate patient activation and enrollment, and broaden its footprint beyond its current 100-plus sites across North America, Europe, India and Australia. Backers listed include Intrepid Growth Partners, Google Ventures, EDBI, and existing investors Insight Partners and Obvious Ventures. Iterative also cited metrics including faster activation timelines and higher-than-average patient enrollment performance.
