Atlas Oncology Partners

Atlas Oncology Partners (operating at atlasoncpartners.com and atlasonc.com) is a value-based oncology care enablement platform engineered to bridge community oncology practices with whole-person supportive care. Founded in 2025 by Kate Barnard Roberts, Dr. David Johnson, and Dr. Gabrielle Rocque in collaboration with Rubicon Founders and headquartered in Nashville, Tennessee, Atlas aligns financial incentives across payers, providers, and patients by assuming full medical cost risk for cancer populations. Rather than displacing existing oncologists, the platform embeds interdisciplinary extended care teams directly into local community practices—offering 24/7 symptom triage, care coordination, psychosocial support, advanced care planning, and on-site management of cancer-adjacent conditions. Under the hood, Atlas leverages an advanced health economics, actuarial, and analytics stack—including multi-scenario contract modeling and dynamic risk stratification—to negotiate outcomes-based contracts across Medicare Advantage and commercial plans. Backed by a $28M Series A led by Flare Capital Partners and Rubicon Founders, Atlas lowers non-drug total cost of care, prevents avoidable emergency room visits, and maximizes quality of life for patients undergoing active treatment.
