Customers & use cases

Built where being wrong is expensive.

The work spans regulated industries, from carrier integration to editorial content. Anywhere a wrong output is costly and every output has to be provable.

Use cases

Where we build

Two areas of deep, regulated work today. Each is a small family of models that share one evidence pack and one accepted format.

Area 01

Carrier integration

Getting regulated data to move correctly between a platform and every carrier it touches, with the tests and provenance to prove it.

Integration model

Validates data flowing to and from each carrier against its schema and rules, catching mismatches before they reach production.

Mapping-doc model

Reads a carrier's integration spec and produces the field mappings and transforms, each one cited back to the doc it came from.

QA generator

Turns the integration rules into test suites, so every mapping ships with the tests that prove it holds.

Area 02

Content generation & editorial

Producing editorial content that clears compliance the first time, grounded in approved sources and gated on the rules.

Editorial-gate model

Checks every draft against editorial standards, disclosures, and regulatory rules. It refuses to pass what it cannot cite.

Writer model

Drafts in the house voice for each vertical, grounded only in approved sources, never inventing facts.

Data-analyst model

Turns performance data into briefs a human can act on: the query, the finding, and the source it came from.

Featured case · Regulated coding agent

15,000 rules, one 20-year codebase

A generic coding agent skips the rule it cannot see. This one refuses to ship until it can point at the rule, the code, and the test.

Across industries

The same method travels.

The evidence pack that clears one committee clears the next. A few places it goes:

Healthcare

Prior-authorization drafting · clinical-note structuring, cited back to the chart.

Banking & finance

Credit-memo drafting · adverse-action reason codes · model-risk documentation.

Insurance

Rating and pricing models · claims triage, each with the evidence pack.

Scientific & R&D

Literature synthesis · protocol drafting · lab-data QA with provenance.

Legal

Contract review and clause extraction, cited to the source paragraph.

Public sector

Records classification · FOIA redaction with an auditable trail.

Every change carries its record.

Every change shows which rule it satisfies, which code it touched, and which test covers it, traced end to end. A reviewer can follow it and a regulator can trust it. It is the same provenance an owned model carries into your committee.
