A scoreboard for doctors
Garner Health does something that sounds almost too simple to be a company. It reads the receipts. Every visit, every procedure, every prescription in America leaves a paper trail in the form of an insurance claim. Pile up enough of them - Garner says more than 60 billion - and patterns appear. Which surgeon's patients come back for a second operation. Which specialist orders the scan that actually finds the problem. Which primary care doctor keeps people healthy and out of the emergency room.
Reber's company turns that wall of data into a quality score, then does the part nobody else does: it pays patients to choose the doctors who score well. Employers fund the incentive. Garner builds the directory and runs the math. The pitch to a company's benefits team is almost suspiciously tidy - better care and lower spending, without forcing anyone to switch health plans or networks.

The core issue is a failure of the market, and the solution needs to be a market solution.- Nick Reber
What a hedge fund taught him about hospitals
Before healthcare, Reber spent ten years at Bridgewater Associates, the famously analytical hedge fund built by Ray Dalio. He graduated from Brown University in 2006 and went more or less straight into the machine, eventually becoming a partner and co-head of Research Analytics. The job, stripped down, was this: take a chaotic system with millions of moving parts, and find the signal that tells you what is actually working.
That is a strange resume for a healthcare founder, and it is also the entire point. Reber looks at American medicine the way a markets person looks at a mispriced asset. In nearly every market, buyers reward the good suppliers and starve the bad ones. Healthcare broke that loop. Patients rarely know who the good doctors are, prices are invisible until the bill arrives, and the person choosing the care is almost never the person paying for it.
After Bridgewater, he joined the leadership team at Oscar Health, the insurance startup, where he worked on analytics and provider networks as the company grew past $2 billion in revenue. It was a front-row seat to the same problem from the inside. Then in 2019 he left to build the fix himself.
How Garner actually works
The frustrated customer who built the product
Like a lot of good companies, Garner started as a complaint. Reber ran into the wall every patient eventually hits - the maddening difficulty of simply finding out which doctor is actually good at the specific thing you need. He had spent a career measuring quality in complex systems, and here was the most important system of all operating with almost no usable measurement at the consumer level.
His first instinct was to sell the answer to hospitals and health systems. They pushed back. So he pivoted to the people who feel the cost most directly: employers paying for their workers' health plans. That pivot is the whole business. Garner does not try to reform medicine from the inside. It changes who patients see by changing what they know - and by putting a little money behind the nudge.
The proof point is almost a punchline. Garner's product was eventually rolled into the employee benefits package at Bridgewater Associates. His old firm became his customer.
There is no consumer that is actually holding the suppliers accountable the way there is in almost every other market.- Nick Reber
A company built on accountability
Reber's definition of a good doctor is deliberately unsentimental: one who delivers high-quality care at an efficient cost. Both halves matter. A provider who gets great results but orders a fortune in unnecessary tests fails the test. So does the cheap one whose patients keep coming back sicker. The bars below are a rough sketch of where Garner claims its leverage sits.
The funding suggests investors buy the thesis. In 2026 Garner raised $100 million in Series E money at a reported $2.74 billion valuation, in a round led by Index Ventures with a guest list that reads like a Silicon Valley roll call - Sequoia Capital, Founders Fund, Thrive Capital, Kleiner Perkins, Redpoint and others. Total money raised across the company's life runs to roughly $279 million.
Staring into the abyss, on purpose
For someone so committed to data, Reber is unusually candid about the parts of the job no spreadsheet can model. He has described building a company as a constant exercise in confronting self-doubt - the kind of line you only write if you have actually lived it. The Bridgewater years left a mark there too. The fund's house religion of radical honesty and continuous learning, the relentless question of am I sure I'm right, shows up in how he frames the mission: not as a moral crusade against doctors, but as a market that lost its feedback loop and needs it rebuilt.
It is a quieter kind of ambition than the usual founder noise. No promise to disrupt medicine overnight. Just a stubborn bet that if you measure quality honestly and put real money behind better choices, an enormous amount of waste quietly drains out of the system and lands back in the pockets of families and the employers who insure them. That is the trillion-dollar inefficiency Reber set out to diagnose - and, he hopes, to bill for fixing.
On what makes a great doctor
"An excellent healthcare provider is one that delivers high-quality care at an efficient cost." It is a definition with no romance in it, and that is the point. Garner is an argument that the warm, fuzzy way we pick doctors - reputation, bedside manner, a friend's recommendation - is exactly why the system stays broken, and that the boring, measurable stuff is what actually changes outcomes.
