Vector Systems

Vector Systems, PBC develops and publishes VectorOS, a legal operating system that consolidates matters, executed documents, company records, data rooms and AI-powered intelligence into a single workspace for companies and their legal counsel. The platform is designed to ground answers in a client's own records rather than external sources. Features include Vector Intelligence, which answers questions from permitted documents; a Smart Data Room with integrations for Google Drive, OneDrive, Box and Dropbox; Legal Health Checks for reviewing corporate and equity records; AI Redlining for third-party documents; and Lawyer in the Loop, which provides senior counsel oversight of AI-assisted work.

The company's engineering work spans AI-powered document intelligence, document automation and review across DOCX, XLSX and PPTX files, Office Open XML processing, and data room and records management. It also contributes to open-source software: Blackline, an Office Open XML toolkit for DOCX, XLSX and PPTX files written in Rust, is MIT licensed and publicly available.

Vector Systems operates as a Public Benefit Corporation and is backed by Y Combinator, Base10 and Transpose Platform. Legal services are delivered through Vector Legal, P.C., a licensed California law firm, alongside Vector Systems, PBC as the software publisher. The stated focus of the product is accessible legal technology for in-house legal teams and outside counsel, with an emphasis on keeping human legal judgment in the loop on AI-generated work.
