§LegalTech & Document AI

LegalTech without the
AI hallucination tax.

We build document-AI systems that paralegals and attorneys actually trust — grounded retrieval, citations on every claim, evals on every deploy. We have already shipped a pipeline that cut drafting time by 60% across 200+ matters, with zero unreviewed outputs leaving the system.

60% drafting time reduction · 100% reviewed outputs

Compliance & data

Built right.
From day one.

Compliance is an architectural concern, not a checkbox. We scope the regulatory surface before writing a line of code — so you are not retrofitting controls at Series A.

Privilege & confidentiality

Per-matter data isolation, no cross-tenant leakage in vector stores or LLM calls.

Audit trails

Every model call, prompt version, and output logged for review and reproducibility.
