AD VERBUM

At a Glance

AD VERBUM is a Northern European, family-owned B2B language service provider with 25+ years of experience, built for regulated, high-stakes industries. It combines a proprietary, in-house LLM-based AI with a 100% AI+HUMAN workflow and a network of 3,500+ subject-matter expert linguists to deliver precision translations across Life Sciences, Legal, Finance, and Manufacturing. Expect enterprise-grade security, strict terminology enforcement, and turnaround speeds reported at 3x–5x faster than traditional workflows.

Core Features

AD VERBUM’s core capability is its Proprietary AI+HUMAN translation workflow: the platform ingests your Translation Memories and Terminology Databases, generates drafts with an in-house LLM constrained by client glossaries and style guides, and routes output to certified Subject Matter Experts for refinement and QA. The service supports 150+ languages and regional variants, integrates deeply with TM and TB assets, and adheres to international standards for quality and security (including ISO and GDPR/HIPAA compliance). The result is context-aware translation that enforces terminology and protects sensitive IP in a private EU-hosted environment.

Pros

• Cost reduction at scale: AD VERBUM reduces translation costs by at least 30%, which compounds across large documentation portfolios and regulatory submission cycles.

• Certified quality and compliance: The service uses certified professional linguists and a rigorous QA pipeline to meet industry standards and regulatory requirements.

• Specialized industry coverage: Life Sciences, Legal, Finance, and Manufacturing workflows include domain-specific reviewer teams who verify technical accuracy and regulatory alignment.

• Data sovereignty and security: Operating on a private EU cloud with ISO 27001 controls prevents public data exposure and mitigates GDPR and HIPAA risks for sensitive content.

• Speed without compromise: The AI accelerates first-draft creation, while human SMEs ensure final outputs are compliant and defensible.

Who It’s For

AD VERBUM is designed for companies that cannot accept translation risk: pharmaceutical sponsors preparing regulatory dossiers, medical device manufacturers producing MDR-aligned manuals, legal teams handling contract localization, and financial institutions translating audited reports. If your workflows require strict terminology enforcement, traceable TM/TB integration, and demonstrable data security, AD VERBUM fits your procurement and compliance requirements.

Unique Value Proposition

AD VERBUM’s unique value lies in pairing a proprietary, in-house LLM with a mandatory AI+HUMAN workflow hosted on EU servers. This architecture enforces client glossaries and style rules at scale—something public NMT cannot guarantee—while eliminating data leakage into public clouds. The outcome is reproducible, auditable translations that hold up under regulatory scrutiny: terminologies are locked, context is preserved across large-document sets, and sensitive IP and patient data remain inside a secure, certified environment. In short: speed from AI, accountability from humans, and sovereignty from private infrastructure.

Real World Use Case

A pharmaceutical company used AD VERBUM to translate clinical study reports and regulatory submission packages into multiple languages. The platform ingested existing TMs and TBs, produced LLM-generated drafts, and routed those drafts to medically qualified linguists for SME review—resulting in compliant submissions delivered on accelerated timelines and with consistent terminology across all documents.

Pricing

Pricing is not posted publicly; AD VERBUM requires a request for a quote to tailor costs to volume, language combination, and required SME levels. This ensures pricing aligns with compliance needs and project complexity.
