About the Axiom Foundation
The world's rules, encoded. Axiom Foundation is the nonprofit home of The Axiom Project, with Axiom Labs prototyping the applied layer on top of the canonical rules core.
Our mission
Our mission is to make legal rules machine-readable, verifiable, and accessible to everyone. The Axiom Project focuses on the bounded public-good core: source documents, encoded rules, provenance, and validation. Axiom Labs prototypes intake, packaging, and other applied tooling on top. We're a fiscally sponsored project of the PSL Foundation.
How we're organized
Axiom Foundation
The nonprofit steward: long-term governance, funding, community, and public accountability.
The Axiom Project
The bounded core: canonical rules encodings, provenance, compilers, and validation.
Axiom Labs
The applied layer: reference intake flows, adaptive questioning pilots, and delivery tooling built on top of the core.
What we do
Axiom
Open platform for exploring encoded law. The Archive holds 53 USC titles, 570+ IRS guidance documents, and 48 states. Axiom brings together source documents, RuleSpec encodings, and validation results.
RuleSpec
RuleSpec DSL for encoding statutes with citations, temporal versioning, and tests. Purpose-built for legal encoding.
Encoder
AI-powered encoding pipeline with 3-tier validation. Automated statute encoding with CI testing, oracle validation, and LLM review.
Team
The Axiom Foundation is led by Max Ghenis, who also founded PolicyEngine. We're an open-source community project and welcome contributors from all backgrounds — developers, policy experts, legal researchers, and anyone passionate about making rules more transparent and accessible.
