Investing in Luminai: Transforming Operations for a $5T Industry

At Peak XV, we spend our time searching for exceptional founders, solving difficult problems. Often, very rewarding companies can be built in areas where complexity has quietly accumulated over decades.

US healthcare presents one such opportunity. Administrative overhead today accounts for nearly a quarter of total healthcare spending. Over many years, hospitals have invested heavily in software and outsourced services to manage this complexity. Yet much of the underlying operational burden remains manual, fragmented, and difficult to scale. Over the past decade, different automation systems promised efficiency gains, but often proved fragile and difficult to maintain. Many solutions relied on brittle workflows that broke under real-world complexity. 

Today, we are excited to announce our partnership with Luminai, as the lead investor for their $38 million Series B. Luminai is building an AI platform for health system operations that addresses one of the most persistent structural challenges in delivering healthcare at scale in the United States. 

In late 2024, I met Kesava for the first time. A Thiel Fellow and a world-record holder in solving Rubik’s cubes, Kesava immediately struck me as a high potential founder who is extremely ambitious, and brings an outsider’s perspective to the healthcare industry. What impressed us was his systems thinking to build an AI platform versus easy tactical tools that are thin wrappers on LLMs.

He believed that health systems needed a single, unified platform to bring together hundreds of processes and replace dozens of legacy software all at once. Even though it might seem like a hard problem to solve, if it was possible, it had to be attempted in stages.

Luminai’s platform uses frontier AI models to transform unstructured operational workflows into inspectable, auditable programs. This distinction matters deeply in healthcare, where reliability and transparency are essential. Health systems need infrastructure they can trust, operate, and build upon. What previously required months of implementation can now be achieved in days. This dramatically improves both speed and economics for healthcare providers.

Over the last few quarters we have been positively surprised by the deep partnerships Luminai is able to establish with large health systems. As a relatively young company, Luminai is already working with dozens of provider institutions. And the most recent biggest endorsement is their enterprise-wide rollout partnership with the Cleveland Clinic, one of the most globally respected health systems serving nearly 16 million patients. With many more enterprise wide transformation partnerships in the pipeline, Luminai is well positioned to become one of the top AI platform companies for US healthcare. 

We are excited to partner with Kesava and the entire Luminai team as they build what we believe will become a foundational AI platform company for US healthcare operations.
