After driving breakneck growth at leading healthcare companies, Duncan set to accelerate Harrison.ai’s Americas expansion
Boston, Massachusetts – May 5, 2025 — Harrison.ai, a leading global healthtech company and developer of AI-powered diagnostic support and workflow solutions, today announced the appointment of Josh Duncan as Chief Growth Officer, Americas. In this new role, Duncan will lead operations across the United States and the broader Americas region, with a focus on accelerating market adoption, deepening customer partnerships, and strengthening Harrison.ai’s position as the leader in AI-driven healthcare.
Duncan’s appointment signals Harrison’s commitment to meaningful, long-term growth in the Americas and reflects the company’s broader mission to use advanced technologies to extend the reach of medical expertise and improve health outcomes worldwide. Harrison’s focus on rapidly building a U.S. presence builds on its swift rise to success as a global leader in healthcare AI across the UK, EMEA, and APAC.
“Josh is a visionary commercial leader who understands not just how to drive growth, but how to align it with meaningful, systemic change in healthcare,” said Dr. Aengus Tran, Co-Founder and CEO of Harrison.ai. “His ability to anticipate where the market is heading — and to build teams and partnerships that deliver real clinical and economic impact — makes him uniquely equipped to lead our expansion across the Americas.”
Harrison’s radiology and pathology tools assist clinicians with identifying signs of cancer and other critical illnesses earlier, improving treatment decisions and patient outcomes. The company’s technology is currently deployed in 1,000+ healthcare facilities across the globe and has already received 12 FDA clearances. One of its CT Brain algorithms earned the FDA’s rarely granted Breakthrough Device Designation, recognizing its potential to significantly improve the diagnosis of life-threatening or debilitating conditions. Harrison.ai has also qualified for Medicare reimbursement under the New Technology Add-on Payment (NTAP) program.
Duncan joins Harrison following four years at Rad AI, where he served as Senior Vice President of Sales, Marketing, and Customer Success. Under his commercial leadership, Rad AI became one of the fastest-growing companies in healthcare technology, forging partnerships with some of the most prominent radiology practices and health systems in the US and Canada. At Harrison, he will be responsible for building and leading the Americas team, scaling strategic partnerships, and shaping how Harrison delivers clinical and economic value in the Americas region.
“Our work is rooted in solving real challenges — from the increasing burden on diagnostic services to the inequality in access to quality care,” said Duncan. “I’m excited to join Harrison.ai at a critical time of growth and look forward to leading at a company that’s building scalable, clinically validated AI solutions capable of making a global impact.”
The urgency to increase clinician capacity is intensifying, with new cancer cases expected to rise to 35 million by 2050, according to the World Health Organization (WHO), with radiologists and pathologists playing a crucial role in diagnosing these cases. Harrison.ai helps clinicians manage this overwhelming demand by serving as a “second pair of eyes”, reducing the burden on human resources and ultimately saving lives by detecting critical conditions earlier and more quickly.
“Josh brings a rare combination of commercial acumen, deep radiology market expertise, and a genuine commitment to building lasting customer relationships,” said Dimitry Tran, Co-Founder of Harrison.ai. “With Josh leading the Americas Commercial team, we look forward to bringing our best-in-class, life-saving technology — already widely used globally — to healthcare systems in the U.S. and across the Americas. This will help address some of the most pressing challenges facing healthcare, including capacity, physician burnout, and quality of care, while also providing the financial security that health systems and physician groups need through NTAP.”
