A clinician who spent 18 years in the emergency room, now building the company that decides what happens after the hospital doors close behind you.
There is a moment in nearly every hospital stay that no one owns. The paperwork is signed, the ride home is arranged, and a patient walks out the door into a stretch of days where a lot can go wrong and almost no one is watching. Caroline Hodge decided that moment deserved a company.
Hodge is the co-founder and chief executive of Dimer Health, a company built around a deceptively simple idea: someone should be accountable for you after you leave the hospital, not just while you are inside it. She came to that conviction the hard way, through nearly two decades on the clinical front line. As a physician associate, she logged 18 years in emergency medicine, the specialty where the system's gaps show up first and most vividly.
The emergency room is where you learn how the rest of the machine is running. Patients arrive who were treated well and discharged properly and still ended up back in a waiting room days later, not because the medicine failed but because the handoff did. Hodge saw the pattern often enough that it stopped looking like bad luck and started looking like a design flaw.
Before she was a founder, she was an operator at scale. Hodge served as National Vice President for Advanced Practice Providers at Envision Healthcare, then as National Vice President of Clinical Operations, Growth, and Strategy at DocGo. Those roles gave her something a lot of health-tech founders lack: a working knowledge of how care actually gets delivered across thousands of encounters, and how quickly good intentions dissolve when they hit real operations.
In 2023, she stopped diagnosing the problem from the inside and started building the answer from the outside. Dimer Health was founded with Team8, the Israeli venture-creation firm, which named Hodge a "ProFounder" and backed the company from concept through launch. Her co-founders came from strikingly different worlds: Sarig Reichert, who led Wix Bookings, runs product as chief product officer, and Gidon Coussin, an emergency-medicine physician associate and former IDF paramedic captain, serves as chief strategy officer.
The combination is intentional. Dimer is a technology company, but Hodge insists it is a clinician-led one. The product uses AI to reach patients at scale during their recovery, while licensed clinicians stay accountable for the outcome. That balance - software for reach, humans for judgment - is the whole argument. Automate the follow-up and you get volume without trust. Staff it entirely with people and you cannot afford to serve everyone. Dimer's bet is that you need both, wired together deliberately.
The company gave the role a name that Hodge repeats like a thesis statement: the Transitionist. It is the clinician who owns the patient from discharge through home recovery, the missing counterpart to the hospitalist who owns the patient inside the building.
"The hospitalist did not exist before 1996. Today there are more than 60,000. That specialty emerged because outcomes were proven and the system adapted. The Transitionist is next." Caroline Hodge, Co-Founder & CEO, Dimer Health
Hodge's favorite argument is a chart she carries in her head. In 1996 the hospitalist was not a job. Today it is one of the largest specialties in American medicine, tens of thousands strong, because someone proved that a dedicated role produced better outcomes and the system reorganized to fund it.
She points to that arc for a reason. New medical specialties do not appear because they sound good; they appear when the results are undeniable and the economics finally line up. Hodge is trying to walk the Transitionist down the same path, and she treats the metrics as the argument.
Dimer says its model has delivered up to a 67 percent reduction in unnecessary readmissions, kept Net Promoter Scores above 90, and grown revenue 30 percent a quarter across four straight quarters. For investors, that last set of numbers is the tell. It suggests the model is not just clinically effective but financially repeatable.

Chief Product Officer. Previously led Wix Bookings, bringing consumer-grade product discipline to a clinical setting.
Chief Strategy Officer. An emergency-medicine physician associate and former IDF paramedic captain.
The $13.5M Series A was led by venture-creation firm Team8 and Bill Ackman's Table Management, with Silver Circle and TechAviv participating.
She carries three credentials that rarely land on the same business card: MS, PA-C, and MBA. She still thinks like a clinician first.
Her co-founders come from Wix and the Israel Defense Forces - a product leader and a paramedic captain sharing a cap table with an ER veteran.
Dimer's Series A drew in the firm run by activist investor Bill Ackman, an unusual name on a clinical-care round.
She frames a new job title, the Transitionist, as the natural sequel to the hospitalist - and treats that comparison as her north star.
Hodge is not trying to sell a better app. She is trying to make a role permanent.
The aspiration behind Dimer Health is larger than any single feature or funding round. Hodge wants structured, accountable care in the days after discharge to become the standard rather than the exception, and she wants the Transitionist to become a recognized specialty the way the hospitalist did a generation ago. It is an audacious goal precisely because it depends on the system changing its own habits.
What makes the bet credible is the shape of the person making it. Hodge has been the clinician doing the work, the executive running the operation, and now the founder assembling the pieces. She has seen the gap from every angle, and she has spent a career refusing to accept that the space between the hospital and home should be a place where care simply stops. Whether the Transitionist becomes as common as the hospitalist is still an open question. Hodge is spending her days trying to make the answer obvious.
