An applied-AI company built to prove its work.
AI pilots rarely stall because the model is weak. They stall because nobody can show the person carrying the risk that the system is accurate, secure and safe to depend on: a CISO, a plant safety manager, an agency's authorizing official. We call that the Sign-off Gap. We prepare the evidence to close it, and that person decides.
Who we are
Artheus is an applied AI, digital engineering and AI test and assurance firm. When the three are bought separately, the work breaks where they meet: an assistant nobody can trace, a model nobody can verify, an AI test that starts after the build. We run all three under one method, the Proof-First Lifecycle, for companies and government agencies alike. You approve the test before we build, and nothing goes live until it passes.
Move AI from the demo into daily work, with proof, so the people who make high-stakes decisions can trust what the system tells them.
Why we existCommercial and government, from day one.
Artheus LLC was formed in Virginia in July 2026. We work for manufacturers, energy operators, technology companies, defense suppliers, federal civilian and defense agencies, and international development programs, and hold every engagement to the same standard of proof.
Subject matter experts, fixed scope.
We take on only the work we can staff with subject matter experts, and we name who will do it before you sign. As a new firm, we show our own measured work instead of client logos. We built a document-to-model pipeline at our own expense, scored it on a synthetic test corpus with 40 defects planted on purpose and traced every element to its source page.
Our record so farFive rules for every engagement.
The test comes first
The questions, the pass mark and who signs off are agreed with you in writing. Every later change to the test is recorded, so results are measured against what you approved.
The people who scope it build it
The people you meet in the first conversation build and hand over the work.
Yours to run
You own the code, the data and the test harness. Every build ends with documentation, runbooks and training so your team can run and change it without us.
Security evidence built with the system
Security requirements are set before we build: people and AI agents get only the access their job needs (least privilege), and every request is verified (zero trust). We collect the evidence your assessor or auditor will ask for as we go.
Straight talk
If something will not work, is not ready or is not worth the money, we say so early and in plain language.
How we work: the Proof-First Lifecycle
Skip the tourAgree on the test first
A risk team has more reports than answers. We pick the one question worth answering, check that the data can answer it and agree the pass mark in writing.
You get: a clear question, proof your data can answer it, and a pass mark agreed in writing.
AI Readiness SprintConnect the field to the desk
In transportation, the facts live in sensors along the line. We bring those readings into one pipeline, record where each came from and check for gaps before they reach a decision.
You get: one trusted pipeline, every reading traced to its sensor, and gaps caught before they reach a decision.
Data Readiness and PipelinesBuild a model you can check
For a plant, we turn drawings, manuals and equipment records into a working engineering model, every part traced to its source, with the approved test running on every change.
You get: a working engineering model, every part traced to its source and tested on every change.
Document-to-Model ConversionProve it before anyone trusts it
In a lab, an AI result must hold up. We test the model on results it never saw, red-team it and record how it scored and where it falls short. It passes, or it goes back.
You get: proof the model holds up: scored on results it never saw and red-teamed, with the record to show it.
AI Test & AssuranceSecure what the work depends on
Security requirements are set in the first stage and built in, zero trust included. Here we test the controls and package the evidence for the official who authorizes a defense system.
You get: security built in from day one, tested controls, and an ATO evidence package ready for sign-off.
Zero Trust ArchitectureKeep it working in people's hands
A system pays off only when people use it. Store staff can rehearse a new layout in a headset before opening day. Once live, alarms send it back for re-testing if accuracy drifts.
You get: staff who rehearsed the new layout before opening day, and monitoring that keeps the system accurate after launch.
