Luminai Raises $38M Series B and Deploys Autonomous Referral Processing Agents Across Cleveland Clinic's 23 Hospitals

Luminai, an AI-native enterprise automation platform for healthcare, has closed a $38M Series B led by Peak XV Partners, bringing its total funding to $60M. Simultaneously, the company announced a deployment with Cleveland Clinic to automate referral processing across 23 hospitals and 80,000 employees using autonomous AI agents.

The Workflow

Cleveland Clinic receives thousands of referrals per day. Many still arrive by fax. The manual process requires staff to classify each document, extract clinical and administrative data, match to the correct patient and provider, and route to the appropriate department. It is labor-intensive, error-prone, and bottlenecked by the volume of unstructured documents.

Luminai’s agents now handle this end-to-end. According to HIT Consultant, the system ingests documents, determines whether they are referrals, extracts key data, matches to patient and provider records, and routes to the correct destination. The system achieves over 80% automation on document types that previously required full human review.

When confidence falls below threshold, the system routes to a human operator with context pre-populated. That human decision feeds back into the system as a learning loop, according to HIT Consultant.

How It Works Technically

The core challenge, according to CEO Kesava Kirupa Dinakaran in Unshackled VC’s analysis, is unstructured data. “The biggest barrier was unstructured data,” Dinakaran said. “Without structuring that data, you can’t actually automate the workflow.”

Luminai addresses this by encoding each hospital’s specific Standard Operating Procedures (SOPs) into the software. As HIT Consultant reported, the system translates unstructured inputs into actionable data using the exact routing logic a trained human operator would apply. This is distinct from both traditional RPA (which breaks on non-standard fax layouts) and generic LLMs (which lack hospital-specific clinical and business context).

Cleveland Clinic’s Chief Digital Officer told Forbes: “The goal is to reduce administrative burden and allow our caregivers to focus on patient care and more substantial work.”

Funding and Timeline

The $38M Series B was led by Peak XV Partners (formerly Sequoia India/Southeast Asia). Prior investors include General Catalyst (which led the $16M Series A) and Unshackled Ventures (pre-seed in March 2020). Dinakaran was also a Y Combinator Winter 2021 alum, Thiel Fellow, and Forbes 30 Under 30 honoree.

Luminai reports an average time-to-value of 48 days, per HIT Consultant. In enterprise healthcare software, where implementation cycles typically run 18 to 24 months, that speed is a competitive differentiator.

Healthcare as an Agent Deployment Vertical

The Cleveland Clinic deal validates a pattern emerging across healthcare: autonomous agents handling high-volume, document-heavy administrative workflows where the cost of manual processing is measurable and the tolerance for error is bounded by human-in-the-loop fallbacks. The 80% automation figure gives other health systems a concrete benchmark. The partnership is expected to expand across Cleveland Clinic’s broader operations beyond referral processing.
