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.
Ari Baranian is the co-founder and CEO of Pirros (YC W23), a Los Angeles startup building a detail management platform for architects and structural engineers. A structural engineer turned software builder, he created Pirros to solve a problem he lived daily at his old firm: engineers constantly recreating the same construction details from scratch. Pirros integrates with Revit, automatically extracts and catalogs details with their metadata, and makes a firm's institutional knowledge searchable and reusable. The company is profitable, reached roughly $6M ARR with 300+ firms on the platform, and closed a Series A reported around $15-17M in 2025.
