Greatly Health offers a virtual platform that delivers evidence-based supportive therapies—live expert-led group sessions in exercise, yoga, tai chi, and mindfulness—alongside personalized care planning, symptom tracking, and ongoing coaching. Its program was developed and clinically validated at Memorial Sloan Kettering Cancer Center, where a randomized trial led by the company’s co-founders demonstrated substantial improvements in outcomes, including a 16% absolute survival benefit at two years and large reductions in hospitalizations and treatment disruptions. Greatly serves patients directly and via sponsored programs, including a partnership with a global life sciences company and a patient advocacy group supporting roughly 200 metastatic breast cancer patients. The company aims to expand access through partnerships with health plans, oncology providers, and life sciences firms, and to shift integrative oncology from out-of-pocket or philanthropy-funded care to a reimbursed component of standard cancer treatment. Financially, Greatly recently raised a $4 million seed round to support team growth, technology enhancements, and expansion of its clinical offerings.
