Robert Sepucha, Chief Executive Officer
Sepucha joins Atlas at an inflection point in the company’s growth. Having just secured a significant funding round in partnership with investors Rubicon Founders and Flare Capital Partners, including a commitment to make available up to $100 million in additional capital, Atlas is establishing itself as a market leader. It currently partners with oncology practices across three states and has entered into a value-based arrangement with a large national payer. Atlas is poised for expansion, with a robust pipeline of additional practice partnerships for launch in the remainder of this year and 2027.
“As healthcare moves toward value, providing excellent clinical care is only the starting point,” said Sepucha. “Cancer patients need coordinated support that treats the whole person, and oncologists need the resources to provide it. Atlas’ unique clinical model provides community oncologists with those capabilities while allowing them to remain at the center of their patients’ care. I am excited to join the Atlas team to partner with community oncologists to help cancer patients live their best lives.”
Sepucha joins Atlas from Interwell Health, the nation’s largest value-based kidney care provider, where he led a team caring for more than 150,000 Americans with advanced kidney disease and managed more than $7 billion in total medical cost. As Chief Executive Officer, Sepucha helped lead the organization through a three-way merger of Cricket Health, Interwell Health, and Fresenius Health Partners and into a period of national scale. He previously served as CEO of Cricket Health and spent nearly a decade in government affairs and policy at Fresenius Medical Care. His experience building physician partnerships, working with national health plans, and scaling value-based specialty care will be central to Atlas’s next phase of growth.
“Bobby has already done in kidney care much of what we’re setting out to do in oncology: build deep physician partnerships, work with national health plans, and create the infrastructure required to care for complex patients at scale. As Atlas enters its next phase of growth, that experience is incredibly valuable,” said Kate Roberts, co-founder and President of Atlas Oncology Partners.
“Atlas has built real momentum in a short period of time, including partnering with practices in multiple states and establishing a value-based relationship with a national health plan since Atlas’ founding in 2025,” said Matt Kim, Partner at Rubicon Founders. “That traction validates both the need for this model and the opportunity ahead. Bobby has the experience to build on that foundation and help Atlas become a leading national platform for value-based oncology care.”
