Applied AI · Digital engineering · AI test and assurance

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.

How we work The Proof-First Lifecycle, in six scenes. A short scroll-through of one engagement, from agreeing the test to running what we built. Take the tour
What we do

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.

Decide01

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 more
Model02

Digital 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 Conversion
Prove03

AI 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 more
Ready04

Training & 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 more
Secure05

Cybersecurity & 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 more
Modernize06

Data & 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 more
Connect07

Spectrum & 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 more
Why Artheus

Four things you can hold us to.

01

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.

02

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.

03

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.

04

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.

Careers

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.
