Lattice Health

Lattice Health is a Y Combinator (Spring 2026) healthcare company building AI governance as a managed service for hospitals. The platform sits beside an existing clinical stack and taps the HL7 and DICOM signals that deployed imaging and clinical AI models already emit, with no rip-and-replace integration, then continuously measures population drift (PSI), subgroup fairness disparity under HHS Section 1557, latency against target, and silent vendor model-update detection across every vendor model running in production. Rather than another dashboard, Lattice delivers a per-role signed PDF report each morning to IT directors, CMIO/CIO, and compliance officers, cryptographically signed with the institution's own signing key so any recipient, including outside counsel or a regulator, can verify the artifact offline with standard open-source tooling and no Lattice account or infrastructure. Radiologist thumbs-up/thumbs-down feedback on AI results is aggregated at model level and folded into the next morning's findings. The company positions itself around standards alignment (IHE UPS-RS work-list status, AI-Results and ERA classification, ONC HTI-1, FDA Predetermined Change Control Plan envelopes with automatic breach detection) and HIPAA-safe egress with a strict-mode PHI redactor, deployed on-premise or in the customer's private cloud so PHI stays behind the hospital firewall. As of this profile Lattice Health publishes no public developer portal, API documentation, machine-readable API specification, SDKs, or pricing; it is a pre-public-API company tracked here as an AI governance and clinical AI oversight lead.

Lattice Health is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Health IT, Artificial Intelligence, and AI Governance.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/lattice-health: open an issue to ask a question, or submit a pull request to add artifacts.
