Engineering intelligence.Securing agency.

We design, attack, evaluate, and ship consequential AI systems for leaders who need more than a convincing prototype.

INDEPENDENT AI LAB + ADVISORYDENVER · WORKING GLOBALLY

Agency changes
the risk model.

When software can plan, choose tools, spend resources, and act on someone’s behalf, every abstraction becomes a trust boundary. We help teams make those boundaries explicit, testable, and resilient.

How we work

Four ways into the problem.

02ATTACK / DEFEND

AI security

Threat modeling, adversarial testing, red teaming, permissions, control design, and operational defenses for systems that reason and act.

03PROVE

Evals & reliability

Curated datasets, scenario evaluations, deterministic and LLM judges, failure taxonomies, regression gates, and measurable improvement loops.

04LEAD

Technical advisory

Architecture direction, build-vs-buy decisions, platform strategy, executive counsel, and hands-on enablement for senior teams.

OPEN-SOURCE SECURITY RESEARCH

ExploitHunter

A local-first offensive-security and agent-evaluation lab for studying how models discover, validate, and communicate findings across long-running attack workflows.
