## Summary

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.

## Company Overview

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.
