Company Profile

About VetRx Ledger

We build compliance infrastructure for veterinary medicine. VetRx Ledger is the purpose-built controlled-substance logbook for multi-DVM hospitals — replacing paper binders and EMR workarounds with a DEA-aligned, audit-grade, offline-capable platform that works at the speed of clinical practice.

Mission

“Make DEA-compliant C-II recordkeeping as fast, reliable, and defensible as the clinical care it documents.”

What we stand for

Compliance is a feature, not a checkbox

Every design decision is anchored to 21 CFR §1304.04. Dual-witness enforcement, append-only audit logs, and hash-chain verification aren't add-ons — they're the core.

Speed and rigor aren't opposites

Veterinary techs deserve tools that match their pace. Under 20 seconds per event isn't a marketing claim — it's a design constraint that shaped every UX decision.

Offline-first because hospitals don't stop

Network outages happen. Our PWA queues every event in IndexedDB and syncs when connectivity returns. Patient care should never wait for the internet.

Privacy by default

AES-256-GCM field encryption, minimal PII collection, and badge-number-only mode mean clinic data stays in the clinic.

Built from discovery, not assumption

VetRx Ledger started with 50+ interviews across solo practices, multi-DVM hospitals, and corporate veterinary groups. We heard the same frustrations everywhere: paper logs scanned and filed after the fact, EMR add-ons that technically exist but fail the dual-witness requirement, no running balances between reconciliation cycles, and zero chain-of-custody for DEA audit defense.

The product roadmap is anchored to a validated pain-point hierarchy, a persona priority order (Practice Manager → Lead Tech → DVM Owner → Corporate Ops), and a competitor matrix that confirmed: no purpose-built C-II logbook targets the 2–15 DVM segment.

The full HBS-style customer discovery — coded interview quotes, journey map, assumptions log, hypotheses set, and DEA alignment document — is available on request to investors, partners, and compliance consultants.
