Decision-grade AI, proven before anyone depends on it.
Artheus builds AI and engineering models for defense programs, federal agencies and the companies that supply them, from your own documents and data. Every answer and model element points to its source, and uncertain calls go to a person. It all runs where your data is allowed to live, including sites with no internet. You approve the test before we build, and nothing goes live until it passes.

Who we are
A working demo is easy. Getting someone accountable to sign for it is not. We call that the Sign-off Gap. Artheus closes it with one method, the Proof-First Lifecycle, across applied AI, digital engineering and AI test and assurance, so the system that answers the question can also defend its answer.
Pick one problem to solve first.
Each starts with a named, fixed-scope first step you can begin this quarter, so the engagement is never open-ended.
Applied AI & Decision Support
Assistants and agents that answer only from your own sources, cite the passage behind each answer and log every action.
AI Readiness Sprint and moreDigital Engineering
Engineering documents become a model engineers can query and check. Our pipeline, measured on our own synthetic test corpus, traced every element to its source page (technology readiness level 3).
Document-to-Model ConversionAI Test & Assurance
AI tested against a pass mark locked before development, red-teamed the way an adversary would attack it and measured after launch, with evidence your reviewer can check.
AI Test and Evaluation and moreTraining & Readiness
Check that each person understood each safety-critical step, in their own language, and put the right manual page in front of maintenance crews at the job. FirstShift is our working prototype.
FirstShift and moreCybersecurity & CMMC Readiness
Evidence an assessor or auditor can check: CMMC readiness against NIST SP 800-171 Rev. 2, zero trust designed to NIST SP 800-207, and plant control systems protected without risking uptime.
CMMC and NIST SP 800-171 Readiness and moreData & Modernization
Replace legacy systems one function at a time behind a stable interface, with a way back at every step, and test your data before any AI is built on it.
Incremental Modernization and moreSpectrum & Wireless Networks
Plan and test 5G and private wireless networks that share crowded spectrum with the users already there, and prove coverage and reliability before a network scales.
Spectrum Sharing and Coexistence Analysis and moreFour things you can hold us to.
The test comes first
The questions, the pass mark and who signs off are agreed in writing at the start. Any later change to the test is recorded.
Security evidence built with the system
Access rules, logging and control mappings are designed in from the first build, so the evidence your security reviewers need is ready when the system is.
Runs where your data is allowed to live
On your servers, in your private or government cloud, or at a site with no internet, on commercial or open-weight models. We design so your data is not used to train anyone else's model.
Yours to run
You own the code, the data and the test harness. Every build ends with runbooks, documentation and training, so your team can run and change it without us.
Where a wrong answer has a cost.
Here it means a tripped breaker, a failed audit, a part built to the wrong drawing or a mission planned on bad data.
Defense & National Security
Engineering baselines still held in documents, and AI that has to run on the program's own network or at sites with no internet.
ExploreFederal Research & Civilian Agencies
Applied research with the test agreed first, AI built to the practices OMB M-25-21 sets for high-impact uses, and legacy systems modernized while services keep running.
ExploreDefense Suppliers & Technology Companies
CMMC readiness against NIST SP 800-171 Rev. 2, and a nontraditional defense contractor for prototype teams.
ExploreEnergy & Critical Infrastructure
Control systems secured starting with passive asset discovery, and AI that advises while a person approves any control change.
ExploreManufacturing & Industrial
Safety training checked for understanding, and bills of material and drawings reconciled into one model.
ExploreInternational Development
Monitoring and evaluation designed for field data an independent party can verify: collected offline, time-stamped and geotagged.

Help build a new applied-AI firm from the start.
Early hires will build assistants that cite their sources, evaluation harnesses, document-to-model pipelines and zero trust designs, and measure all of it. See our mission, values and open roles.
