Software and research for the parts of medicine doctors were never taught.
GigHz is a physician-led venture studio in West Hollywood, California. We build and operate software businesses in healthcare and data research: clinical AI that supports a physician's judgment, tools and data for the business and money decisions medicine never trained doctors for, and research that uses public data to show what's actually happening.
It's led by Pouyan Golshani, MD, a practicing interventional radiologist. One rule runs through all of it: the software proposes, the physician decides.
Startup credits awarded by AWS and Google Cloud.
What GigHz does
Four areas. Most of the tools in each are free.
Clinical AI
Two products and a shelf of free tools. The physician stays in charge.
- GigHz Precision AI — a radiology reporting assistant. You dictate; it structures the report and suggests the guideline category (Fleischner, LI-RADS, Lung-RADS, Bosniak). You review and sign. $99 a month, free for 90 days with an institutional email.
- Pogosh CDS — chart-aware clinical decision support for clinics and EHR vendors. It reads the chart and returns the labs, imaging, routing and escalation that change management, as coded output software can act on.
- Free clinical tools: imaging appropriateness, CT and MRI protocols, radiation dose, report templates, PERC and Wells, periprocedural anticoagulation, IR CPT coding.
Practice economics & facilities
The numbers behind an ASC, OBL or imaging center.
- CenterIQ — hospital price-transparency rates turned into payer benchmarks and pro formas, so the reimbursement assumption gets checked before the capital is committed. Free to explore.
- ASC, OBL & imaging-center consulting — we've consulted on facility projects and worked alongside consultants in the space. If you're weighing a build, reach out.
- Where this is going — we're interested in building the next generation of ASCs and imaging centers: technologically advanced and AI-enabled from day one.
Physician money
Taxes, debt, real estate and the deals doctors get pitched.
- Free tools: Physician Finance Hub, calculators, and a personal finance course.
- Real estate data — through Repit: ZIP-level housing data, free to search, plus data and research for family offices and funds.
- Oil & gas — we've invested in it ourselves and know where the pitfalls are. The IDC guide and calculator share what we learned.
- CPA introductions — we introduce physicians to accountants we know and trust.
We don't sell investments, place deals, or invest on anyone's behalf. Nothing here is investment, tax or legal advice.
Physician ownership →Research & policy
Public data, practical questions, method published.
- FDA AI devices — of 1,430 authorizations from 1995 to 2025, 76.5% went through the radiology panel. Cureus, 2026
- Hospital prices — posted rates show up to 8-fold geographic variation in commercial prices for IR procedures (medRxiv preprint, not yet peer reviewed).
- California policy briefs — price transparency, SB 503 clinical AI oversight, provider identity in the AI era.
How we build
The physician signs
Every clinical tool drafts or suggests. A clinician reviews, edits and decides. Nothing goes into a report or a chart on its own.
Show the source
When a tool recommends something, it names the guideline behind it. You shouldn't have to take a recommendation on faith.
Collect less
The free tools are designed to work without patient identifiers, and most run entirely in your browser. Data we don't hold can't leak.
Used by the person who built it
The reporting tool gets used in a real reading room by the radiologist who wrote it. Problems show up fast that way.
A note from the founder
Pouyan Golshani, MD
Founder · Interventional radiologist
I've been building websites since I was about ten. I started trading around the same age. Neither habit stopped when medicine started.
Medicine still takes most of my week. I trained in diagnostic radiology at Montefiore and in interventional radiology at Emory, and I practice as an interventional radiologist: ablations, embolizations, vascular work, and a lot of diagnostic reading.
GigHz is where those two habits met. In the reading room I kept running into problems that looked like software problems. A follow-up recommendation that never made it into the impression. A guideline buried in a PDF. Colleagues making seven-figure ownership and investing decisions without data that was sitting in a public file the whole time. So I started building.
GigHz is small. I lead it, and I work with outside help on specific projects. I'd rather tell you that than dress it up.
Some of what we build already runs on its own site: Pogosh, Repit, Savng. The ones that earn it may become their own companies one day. None has yet.

The study people ask about
Thirty years of FDA authorizations, and where clinical AI actually took hold
We went through all 1,430 AI/ML-enabled medical device authorizations on the FDA list from September 1995 to December 2025. Radiology accounts for 1,094 of them. Authorizations rose from about 1.8 a year through 2014 to 264 a year across 2023 to 2025. Psychiatry and behavioral health have none.
The part worth arguing about: clinical AI concentrated where data was already digital and standardized, not where the clinical need was greatest. That gap is now measurable instead of anecdotal.
