About PDI Med

I graduated residency July 1, 2025.
The next day I started building.

Not because I wanted to be a software company. Because I looked for the tool every new OB/GYN physician needs, found that it didn't exist, and decided that wasn't acceptable.

01 — Where This Started

By the time I defend my case list, I'll have four kids. I don't have time to waste.

That's the context every new attending knows. Full practice. Young family. Board requirements. Sleep debt from the last four years that never quite goes away.

Case log collection has always been treated as acceptable suffering. Build your spreadsheet. Go back through charts in June. Reconstruct the gestational age you forgot to note. Piece together the complications from a case six months prior that you now barely remember.

I graduated July 2025. I checked the EMR — queries didn't exist in ABOG format. I asked IT — not possible. I looked for purpose-built software — nothing. Not a single product built specifically for what new OB/GYN attendings have to do in year one of independent practice.

"The tools should exist. They didn't. That bothered me enough to do something about it."

02 — Why Nobody Built This

Because the people who fund software don't feel the problem.

EMR companies build what health systems pay for. Health systems pay for billing infrastructure, compliance tools, and workflow optimization — not for the professional credentialing needs of the physicians inside them. ABOG case log collection is not a billing problem. It's not an institutional problem. It's a physician problem, which meant no one with a budget was asking for a solution.

Board prep companies built question banks. Generic, static, no connection to your actual cases. They solved the wrong problem because the profitable problem was test prep, not the year of case collection that precedes it.

The physicians who needed the tool most — new attendings in their first July — are among the least powerful buyers in healthcare. They're not procurement departments. They're not enterprise contracts. They're individual doctors trying to survive year one with a full panel, a young family, and a 12-month deadline no one is helping them meet.

"Nobody built it because nobody asked for it — and nobody asked because the people who could build it didn't feel it."

03 — The Journey

From a pain point to a patent to a platform.

MILESTONE 01

The Problem

"No tool existed for this. So I built one."

The EMR wasn't built for ABOG case log collection. The software didn't exist. I taught myself Python — not to become a developer, but because the clinical intelligence was already there, in the notes I was already writing. It just needed a way out.

MILESTONE 02

The Call

"Dan called Josh. Two different superpowers. One shared obsession."

I called my twin brother. I had the clinical insight — what physicians actually need, what the architecture had to protect. Josh had spent a decade building and shipping complex systems at a Fortune 5 company. He knew how to turn what I was describing into something real, defensible, and lasting.

MILESTONE 03

The Patent

"Filed first. Shared second. That's how serious we were."

Before we told anyone about this, we filed a patent on the de-identification and clinical intelligence architecture. Not because we feared competition — because the idea deserved to be protected before it was made public. Architecture first. Always.

MILESTONE 04

Physician Zero

"I have the same deadline, the same requirements, and no interest in shipping something that doesn't work."

I am not a neutral observer of this platform. I am collecting my own cases under the same ABOG requirements as every physician who uses it alongside me. The product has been pilot-tested and vetted — and I am the first one to know when something falls short. That proximity is not a coincidence. It is the only accountability structure that matters. If you see a gap, a flaw, or a better way to do this — I want to hear it. Build this with me.

04 — The Founders

Identical twins — one physician, one systems architect — bound by the same discovery: the tools were never built for the people using them.

Dan Bristow MD

Dan Bristow, MD

Clinical Founder

OB/GYN physician. Father of three. Built PDI Med because the gap was real and the existing tools were not.

Josh Bristow

Josh Bristow

Systems Founder

Systems architect. Has built at Fortune 5 scale. Knows the difference between software that works in a demo and software that works in the field.

Dan lives inside the clinical reality. Josh lives inside the system reality. PDI Med exists at the intersection.

05 — Where We're Going

"PHI stays with you. Clinical Intelligence travels."

PDI Med starts in OB/GYN because that's where the gap is sharpest, the trust most fragile, and the need most immediate. Case log collection is a problem every new attending faces alone — and it was one we could solve without compromising what matters: physician sovereignty over their own data.

But this was never just about case logs.

The clinical notes physicians write every day are evidence. The decisions they make in the gray zone — where guidelines end and judgment begins — are evidence that no published trial can generate. That intelligence has always evaporated at the end of a busy day. It's documented but not retrievable. Stored but not reasoned about. Present but not useful.

We are building the infrastructure to change that. Physician by physician. Specialty by specialty. Without surveillance. Without employer dashboards. Without any of the architecture of control that has made physicians rightfully suspicious of clinical data platforms.

The physicians who start with us now are not just using a case log tool. They are the founding layer of something that will change how clinical wisdom travels in medicine.
