Healthcare AI infrastructure · Medical imaging AI governance
Lattice Health
A one person startup building a monitoring and governance layer that watches medical imaging AI after a hospital turns it on, checking whether each model still agrees with the radiologist, whether it is drifting, and whether it works evenly across patient groups.
A morning report instead of a dashboard
Lattice does not build an imaging AI model. It sits beside the ones a hospital already runs, from whichever vendors sold them, and reads the signals those models already emit over HL7 and DICOM. Each morning it turns that into a single signed PDF per reader: an alert log for the IT director, a drift and fairness summary for the CMIO, and a compliance posture readout for the hospital's compliance officer. The idea, as the company describes it on its own site, is that "leadership doesn't log into SaaS; they read email."
The company says it never touches patient care. "Lattice never touches patient care, it only watches, so if Lattice stops, care continues," founder Christine Park wrote in the company's Y Combinator launch post.
The gap it is aimed at
The pitch rests on a specific and fairly narrow claim: once an imaging AI model goes live in a hospital, almost nobody is watching whether it keeps working. "Models drift, a scanner upgrade or a shift in the patient population can quietly degrade accuracy, and performance often varies across patient groups," the launch post says. "Most of that goes unseen today, and it's the hospital, not the vendor, that carries the risk."
Lattice frames the timing around a set of regulatory frameworks converging on the same requirement. "AI is moving into clinical use under a wave of new expectations from the FDA, ONC, and the ACR, and they all point to the same gap: continuous post-deployment monitoring," Park wrote. The company's website names specific frameworks it says it tracks posture against, including ARCH-AI, Assess-AI, ONC's HTI-1 rule, the FDA's predetermined change control plan process, and HHS Section 1557 nondiscrimination requirements for subgroup fairness. Those are company statements about what the product targets, not evidence that Lattice has been evaluated against any of them by a regulator or standards body.
Founder
Lattice Health has one person listed as an active founder: Christine Park. A summary of her background posted to Y Combinator's LinkedIn page at launch said she "spent more than a decade in medicine, including neurosurgery training and deep exposure to radiology workflows," and that "in parallel, she has extensive experience in clinical machine learning research." A separate assessment from an outside reviewer site, the YC Tier List, described her as a "neurosurgery-trained MD" with a CS PhD program underway at Stanford, and called that combination rare for a clinical imaging AI founder.
A Christine Park who was a medical student interested in neurosurgery, with an undergraduate chemistry degree from Dartmouth College and a master's in AI underway at Duke's Pratt School of Engineering, appears in bios published by the Duke Institute for Health Innovation and the Goodwin Lab at Duke, both dated 2021. Whether this is the same Christine Park who founded Lattice Health is not confirmed by any source found for this profile.
Where it stands
Lattice launched publicly on Y Combinator in 2026 with a team of one and, by its own account, no named customers. The launch post asks for introductions to "health system and radiology leaders, CMIOs, and anyone running AI governance at a hospital," along with imaging AI vendors who want their models monitored, language that reads as a company still looking for its first pilots rather than one reporting live deployments. Commenters on the launch post, none identified by full name in the material reviewed for this profile, raised a consistent question: that a drift alert only matters if it reaches someone in the radiology workflow who can act on it, and that the harder product is the loop from an alert to a fixed protocol.
What is proven, and what is still claimed
| Evidence | What the record shows | Source type |
|---|---|---|
| Company registration or filings | No SEC Form D found under the company's name in EDGAR searches as of Sep 25, 2026. | Not found |
| FDA record | No 510(k) or PMA record found. The product is described by the company as a read-only observer of other vendors' models, not itself a diagnostic device, which may be why no clearance record exists. | Not found |
| Clinical trials, NIH or NSF awards, PubMed | No registered trial, no NIH or NSF award, and no PubMed record tied to Lattice Health found. NSF award search returned only unrelated hits from institutions with "Health Sciences" in their name. | Not found |
| Named customers | None. The company's launch post and website both solicit pilots rather than describe live ones. | Company-stated |
| Team | Team size listed as 1 on the YC company page. An outside review independently described the company as a "solo founder." | Public record |
| YC batch | The YC company page lists "Batch: Spring 2026." A review site's URL path for the company uses the slug "s26." | Public record |
| Founder credentials | Described in company-adjacent material as neurosurgery-trained with clinical machine learning research experience. An independent review separately described an MD and MEng with a CS PhD in progress at Stanford. Neither claim carries a named degree-granting record in the sources reviewed. | Independent, unverified |
Read plainly: Lattice Health is a very new company with a clearly stated product idea and no public evidence yet of a working deployment, a paying customer, a clinical evaluation, or outside capital. The strongest thing on the record is the founder's stated clinical and machine learning background, and even that rests on company-adjacent summaries rather than an independently documented history.
What to watch
- Whether Lattice names its first hospital or health system pilot.
- Whether a Form D or a reported funding round appears in SEC or press records.
- Whether the team grows beyond one person.
- Whether any of the compliance frameworks Lattice says it tracks, including ARCH-AI, Assess-AI, ONC HTI-1 and the FDA's predetermined change control plan process, come with a documented third party assessment of the product itself.

“no visible product, no press, no website, no customer traction, and no supporting team, which is a significant structural risk for what is positioned as deep infrastructure play.”

“Every signed artifact verifies with standard tooling against your institution’s published public key. No Lattice infrastructure required.”
