The AI that reads the fax, verifies the insurance, files the claim - and lets a clinician check the work.
Here is a fact about American healthcare that is boring, enormous, and mostly ignored: roughly a quarter of the country's $5 trillion medical spend goes not to treating patients but to the paperwork around treating them. Faxes. Referrals. Insurance verifications. Denial appeals. Someone, somewhere, is retyping a handwritten note into a portal right now. Luminai's entire premise is that this someone should not have to.
The company was founded in 2019 by Kesava Kirupa Dinakaran and Dmitry Dolgopolov, two immigrant founders who, by their own account, paid rent early on by winning hackathons out of a San Francisco hacker house. It started as DigitalBrain, a tool for automating customer-support work - take any multi-click, multi-step process and make it one click. That is a nice pitch. It is also a pitch you can make to almost anyone, which is a problem.
So they did the thing founders are always told to do and rarely actually do: they narrowed. They looked at where the multi-click pain was worst and the budgets were deepest, and the answer was healthcare operations. They rebuilt the product from scratch, rebranded to Luminai, and stopped selling to everyone in order to sell to hospitals. In venture parlance this is a "zoom-in pivot." In plain terms it is choosing to have one hard customer instead of a thousand easy ones.
The bet is that recent AI is finally good enough to handle unstructured medical inputs directly - the fax, the scrawl, the PDF that is really a photo of a PDF - and then execute the whole downstream workflow rather than just flagging a task for a human. Crucially, Luminai keeps a person in the loop. It does not try to be a doctor. It tries to be the forty clicks around the doctor, done correctly, and audited.
Note: cumulative funding figures vary by source (~$57M-$62M); the $38M Series B is confirmed by primary press.
Recent advances in AI have made it possible to handle that complexity directly - not just automate isolated tasks, but execute full workflows reliably.
Luminai converts the mess of healthcare inputs into structured data, then runs the administrative process end to end - with clinician-in-the-loop validation and compliance baked in.
Intake, validation, patient-provider matching, and routing - the flagship workload in the Cleveland Clinic partnership.
Patient registration and insurance verification, handled from unstructured source documents.
Claims processing, denial appeals, and pharmacy renewals - the money side of hospital operations.
HIPAA compliant, SOC 2 Type II, zero data retention on AI models, customer-owned credentials, isolated execution.
Three rounds, one thesis that never wavered: manual labor becomes digital labor.

Joins YC's Summer 2020 batch as DigitalBrain and raises a $3.4M seed round.
Raises a Series A led by General Catalyst and rebrands from DigitalBrain to Luminai.
Refocuses the entire product on healthcare operations - referral, revenue cycle, patient access.
Closes a $38M Series B led by Peak XV and announces an enterprise partnership with Cleveland Clinic.
Luminai is building the intelligent orchestration layer that will define how healthcare operations function in the future.
Kesava holds a Guinness World Record for solving Rubik's cubes - and grew up on a coconut farm in India.
The founders reportedly funded their early days by winning hackathons from a San Francisco hacker house.
The move from support automation to healthcare meant rebuilding the product from scratch - not a rebrand, a re-founding.
Luminai deliberately keeps clinicians in control, automating the workflow around them rather than the clinical judgment itself.
Founder conversations and product context from around the web.
Luminai is an AI-native automation platform for healthcare operations. It converts unstructured inputs like faxes and handwritten notes into structured data and runs end-to-end administrative workflows - referral intake, patient registration, insurance verification, claims and denial appeals - with a clinician in the loop.
Luminai was founded in 2019 by Kesava Kirupa Dinakaran (CEO) and Dmitry Dolgopolov. It went through Y Combinator's Summer 2020 batch, originally under the name DigitalBrain.
Luminai has raised roughly $57-62M across seed, a $16M Series A in 2022, and a $38M Series B in April 2026 led by Peak XV Partners. Exact cumulative totals vary by source.
Yes. Luminai is HIPAA compliant and SOC 2 Type II certified, with controls including zero data retention for its AI models, customer-owned credentials, and isolated execution.
Luminai works with large US health systems. Its flagship partner is Cleveland Clinic, and the company reports working with dozens of provider institutions.
