# Pirros

> Pirros is an AI-powered content intelligence platform for architecture and engineering firms that lets designers find, compare, reuse and standardize Revit details and families across every project, team and office. Founded by former structural engineers Ari Baranian and Peter Johann, the Los Angeles company automatically ingests a firm's historical drawing sets and makes them searchable by geometry - no manual tagging - so designers stop digging through cluttered server folders and start reusing vetted work. Often described as 'GitHub for construction,' Pirros integrates directly with Revit and Autodesk ACC/BIM 360 and serves over 300 firms and 15,000+ users.

- **QA/QC & Approval Workflows** — Built-in quality control, markup, version control and approval workflows so firms can vet details and control which content is reference-only versus standard.
- **Standards Library & Analytics** — Data-driven standards identification plus firm-wide usage analytics and detail-reuse tracking, letting standards libraries grow and self-organize based on what teams actually use.
