The gap between AI capability and audit requirements.

The gap between AI capability and audit requirements.

Large language models hallucinate. They cite sources that do not exist. They present fiction as fact with absolute confidence.

For audit and tax professionals, that is not a minor inconvenience, it is a liability. Your work requires evidence. Your clients expect proof. Generic AI cannot deliver that.

Structured standards. Verifiable results.

Structured standards. Verifiable results.

Prevector provides MCP (Model Context Protocol) servers consisting of structured databases of official standards that AI systems can query directly.

Every response is traced to its source. Every citation points to an exact paragraph. Your AI becomes a research tool you can actually rely on.

What makes us different

Domain expertise

Founded by a Dutch Chartered Accountant with ten years at PwC and Deloitte. We have been on the other side of the table and reviewing workpapers, defending positions and demanding evidence. Prevector is built on that experience: solutions designed for how auditors actually work.

Custom-built, not configured

Behind every Prevector MCP server is a database architected for that specific standard with hierarchy preserved, cross-references mapped and search tools calibrated. CSRD has different retrieval needs than Dutch corporate tax law. We build for those differences instead of forcing everything through a generic pipeline. Precision by design, not by luck.
