The perioperative health company

Surgery has an operating room. Not an operating system.

PERIOME is building it — preparing every patient before surgery, quantifying their readiness, and guiding recovery after. One system, across the entire perioperative window.

Building the clinical infrastructure for perioperative medicine.

The point of view

Cleared is not the same as ready.

Cleared

Safe to proceed.

Medical clearance confirms the patient can survive the procedure. It says nothing about the body walking into it.

Ready

Prepared to recover.

The harder question: is the physiology optimized for what surgery will demand — and for the recovery after?

PERIOME measures the difference — and closes it.

The gap in plain sight

Five people touch the case. None of them owns it.

A PCP clears the patient. A scheduler sets the date. Pre-admission testing runs the labs. An anesthesiologist meets the patient shortly before induction. A surgeon performs the procedure. Every one of them does their job well.

04AnesthesiaManages the anesthetic
05SurgeonPerforms the case

Everyone owns a moment. PERIOME owns the window.

Preparing the body, measuring its readiness, and guiding recovery — across the entire perioperative window.

The comparison

An athlete training for a marathon spends months preparing: building capacity, tapering the final week, fueling for race day, following a structured plan through recovery.
Surgery asks more of the body than a marathon ever will.

Right now, a surgical patient gets a date and a list of instructions: when to stop eating, which medications to hold. Nothing about the body itself.

PERIOME is defining perioperative health for the first time: a partner that optimizes the patient’s readiness before surgery, supports their physiology on the day of surgery, and sees their recovery through after.

Physician-founded

Built by the physicians at the head of the bed.

PERIOME was founded by two board-certified anesthesiologists who identified the same perioperative gap across thousands of cases, and built the infrastructure to close it.

"The science was never the missing piece. The infrastructure was — a way to act on the evidence for every patient, and learn from every outcome. That's what PERIOME is building."

"I can prepare the room, the medications, the plan. The one thing I can't fix at induction is the physiology the patient walks in with. PERIOME is the system built to fix it — for every patient, across the entire window."

PERIOME OS

Medicine built the operating room. PERIOME is building the operating system.

Six layers, one compounding system for the perioperative window. Each builds on the one beneath it — anchored by the protocol available today, and getting smarter with every patient.

The perioperative window

The window opens at scheduling. It closes smarter than it opened.

Tap a stage for detail

The window closes on one patient and opens smarter for the next. Every outcome makes the next patient's care smarter. That compounding loop, not any single product, is the company.

The field

Perioperative medicine has defined where surgical care is going. PERIOME is building the infrastructure to get there.

The direction is set by the specialty itself. Leading anesthesiologists and the field's own institutions have described a future where the perioperative window is a connected, measurable, continuously improving standard of care, not a gap between specialties. The evidence base for perioperative optimization has been accumulating for decades in the peer-reviewed literature. What the field has not had is a company that turns that direction into infrastructure at the point of care. That is what PERIOME is building.

The mission

No patient enters surgery unknown.

Readiness measured before induction. Physiology prepared. Recovery seen in real time. Every outcome makes the next patient's care smarter.

The perioperative window becomes a connected, measurable system, not a gap between specialties. This is perioperative medicine, redefined as intelligence.
