Healthcare startup Luminai raises $38 million for administrative automation
Luminai closed a Series B funding round of $38 million on Thursday, bringing the San Francisco-based startup's total fundraising to $60 million since 2020. Peak XV Partners led the round, with participation from General Catalyst, Y Combinator, and Define Ventures.
The company automates manual administrative workflows in healthcare systems using AI agents and automation. Its platform converts unstructured documents like faxes and PDFs into usable data, applies institution-specific routing rules, and processes work without human intervention in most cases.
How the platform works
Luminai's system operates in three layers, according to CEO Kesava Kirupa Dinakaran. The first layer transforms messy documents into structured data by distinguishing relevant clinical information from noise.
When a health system receives referral faxes, for example, many are not actually referrals. "The rest could be pizza flyers, sales spam, thank-you notes from providers and dozens of other document types mixed in," Dinakaran said. Traditional software cannot distinguish between them. Luminai's model identifies what is a referral, extracts relevant information, and passes clean data to downstream systems.
The second layer is a knowledge graph that learns how each health system operates-its routing rules, policies, exceptions, and decision-making patterns. This allows the system to route referrals automatically, even in complex cases where routing logic isn't documented.
"Every health system has its own unique processes and policies," Dinakaran said. "Luminai encodes that operational logic into versioned, auditable infrastructure, rather than relying on tribal knowledge that lives in people's heads."
The third layer executes workflows using agents that classify documents, match them to patients and providers, route them to departments, and trigger downstream actions. When the system lacks confidence, it routes work to a human operator with full context already prepared.
Administrative burden reduction
Health systems often employ over 100 people whose sole job is processing incoming faxes. Luminai's platform reduces this administrative workload, freeing staff from work that must happen but few chose to do.
Cleveland Clinic is currently using the platform to automate referral management and plans to expand to other high-volume administrative workflows.
The shift reflects a broader trend: health systems want AI platforms that handle complete operational workflows, not just individual tasks. Referral management is the starting point for Luminai, with expansion planned across other administrative processes.
For management professionals, this type of automation raises questions about workforce planning, process redesign, and how to integrate AI systems into existing operations while maintaining quality and compliance.
