Pirros vs Bentley Systems
Side-by-side comparison of AI visibility scores, market position, and capabilities
Blueprint reuse platform for architects and structural engineers finding past design details; $17M Series A with 120% NRR serving 200+ firms competing with Autodesk for AEC drawing management.
About
Pirros is a construction technology company providing a blueprint and drawing management platform for architects, structural engineers, and construction firms — specifically enabling design professionals to find, reuse, and adapt relevant drawings and details from past projects rather than starting from scratch on each new project. Founded by structural engineers Ari Baranian and Peter Johann and backed by Y Combinator, Pirros raised $19 million total including a $17 million Series A in 2024, serving 200+ firms and achieving $3 million ARR with 10% month-over-month growth and 120% net revenue retention.\n\nPirros's platform serves as an intelligent drawing library and search system for engineering and architectural firms — practitioners search for specific design solutions (connection details, structural systems, specification sections) and find relevant drawings from past projects with intelligent filtering by building type, structural system, code version, and other parameters. Rather than each project starting from blank sheets or generic templates, engineers retrieve proven designs from their firm's institutional knowledge base. This reuse reduces drafting time, improves consistency, and prevents re-solving problems that the firm has already addressed on previous projects.\n\nIn 2025, Pirros competes in the AEC (architecture, engineering, construction) software market with Procore, Autodesk (AutoCAD, Revit, BIM 360), and BlueBeam for construction document management. The 120% net revenue retention rate indicates strong expansion within existing accounts — as more teams within a firm use Pirros and contribute drawings to the knowledge base, the value of the platform grows. The engineering firm market is highly relationship-driven, with word-of-mouth between structural engineering firms being an important growth channel. The 2025 strategy focuses on expanding beyond structural engineering to MEP (mechanical, electrical, plumbing) engineering firms, deepening AI search capabilities that surface the most relevant historical details for current projects, and growing from regional to national engineering firm adoption.
Exton PA infrastructure engineering software (NASDAQ: BSY) at $1.35B+ 2024 revenue (91% recurring); Seequent $1.05B (2021), Cesium 3D geospatial (2024), first non-Bentley CEO Nicholas Cumins (Jul 2024) competing with Autodesk Civil 3D.
About
Bentley Systems, Incorporated is an Exton, Pennsylvania-based infrastructure engineering software company — publicly traded on NASDAQ (NASDAQ: BSY) — providing software for the design, construction, operation, and lifecycle management of infrastructure assets including roads, bridges, railways, buildings, industrial plants, power generation, and utilities through approximately 5,200 employees serving engineers and infrastructure organizations in 194 countries with annual revenues of $1.35+ billion in 2024 (91% recurring). Founded on September 5, 1984, by brothers Keith and Barry Bentley in suburban Philadelphia — where Keith had developed CAD software during his tenure at E.I. DuPont — the company grew through five Bentley brothers (Keith, Barry, Scott, Greg, and Ray) into the global infrastructure software leader through 120+ acquisitions over four decades, including Intergraph's civil engineering businesses (2001), Seequent for $1.05 billion (2021, geological and subsurface modeling), and Cesium (2024, 3D geospatial and digital twin platform). On July 1, 2024, Nicholas Cumins became CEO — the first person outside the Bentley family to lead the company in its 40-year history, having previously served as COO — with Greg Bentley transitioning to Executive Chair. Bentley made its NASDAQ IPO on September 23, 2020, and maintains a market capitalization of approximately $15 billion as of October 2024.
