Greatly Health, a healthtech company delivering integrative oncology at scale, has raised a $4 million seed round co-led by Pear VC and Commonweal Ventures, with participation from Flare Capital Partners and strategic investors. The company is building a new category of cancer care by integrating evidence-based supportive therapies, including exercise, nutrition, and mind-body interventions, directly into the cancer treatment journey.
Greatly was founded by digital health executive Chip Stine alongside Dr. Jun Mao, Chief of Integrative Medicine and Wellness at Memorial Sloan Kettering Cancer Center, and Dr. Robert Daly, an Associate Attending Physician at MSK and researcher in cancer care delivery innovation. The company’s virtual program was originally developed and clinically validated at MSK, where a randomized trial led by Greatly’s co-founders demonstrated significant improvements in clinical outcomes compared to usual care, including a 16% absolute improvement in overall survival at two years, a 69% reduction in hospitalization rates, and a 42% reduction in treatment disruptions.
Cancer care represents more than $200 billion in annual U.S. spending, with nearly 40% of individuals diagnosed in their lifetime. Patients face significant symptom burden during treatment, including fatigue, pain, and depression, which often leads to hospitalizations and interruptions in care. Integrative approaches to address these symptoms are recommended in oncology guidelines, but access remains limited and fragmented outside major academic medical centers.
Greatly delivers care through a virtual platform built for the realities of cancer treatment, offering live expert-led group sessions in exercise, yoga, tai chi, and mindfulness, alongside personalized care planning, symptom tracking, and ongoing coaching support. A community-based model where patients participate in live sessions together reduces isolation and improves adherence. The company currently serves patients both directly and through sponsored programs, including a collaboration with a global life sciences company and a patient advocacy group supporting approximately 200 patients with metastatic breast cancer.
Greatly is expanding through partnerships with health plans, oncology providers, and life sciences companies, with a long-term strategy to shift integrative oncology from an out-of-pocket or philanthropy-funded service to a reimbursed component of standard cancer care. The new funding will support team expansion, technology platform enhancement, and broadening of the clinical offering.
KEY QUOTES:
“There is no reason this level of care should be confined to top cancer hospitals. The evidence exists. The model works. The remaining barrier is access. This funding allows us to move with urgency to make integrative oncology a standard part of cancer care.”
Chip Stine, Co-Founder and CEO, Greatly Health
“The magnitude of improvement we observed is comparable to what we’ve seen with recently approved therapies. We believe the mechanism is straightforward: better symptom control enables patients to stay on treatment, avoid hospitalizations, and ultimately achieve better outcomes.”
Dr. Robert Daly, Co-Founder, Greatly Health
“What stood out to us is that this is not a theoretical model. It has already been validated and delivered meaningful improvements across survival, acute care utilization, and medication adherence. Greatly is now taking that proven approach and making it accessible to far more patients through technology and industry partnerships.”
