Pirros

United States-based Pirros operates a software-as-a-service platform that helps architecture, engineering, and construction firms centralize, manage, and track their structural design details. The system functions as a specialized version control repository, integrating directly with drafting tools like Revit to analyze firm metadata, surface reusable design elements, and maintain organized digital blueprints. Operating with a workforce of 36 employees, the company provides its cloud-based document management software to an active customer base of more than 300 design and engineering firms. The enterprise currently generates approximately $6 million in annual recurring revenue and recently secured a $17 million Series A funding round in 2025. Pirros is backed by venture capital firms and strategic industry investors, including Y Combinator, Funders Club, PlanGrid, and Elephant. The organization was founded in 2022 by former structural engineers Ari Baranian and Peter.

High-Level Overview

Pirros is a detail management system designed specifically for the architecture, engineering, and construction (AEC) industry. It provides a cloud-based platform that aggregates, organizes, and makes searchable all the technical details—such as wall assemblies and beam-to-column connections—that firms have developed in past projects. By integrating with industry-standard software like Revit, Pirros enables architects and structural engineers to quickly find, reuse, and download these details, significantly reducing redundant work and accelerating project delivery. The platform primarily serves AEC professionals who need efficient access to historical design data to improve quality and productivity[1][2][5].

Founded in 2022 and headquartered in Los Angeles, Pirros is reshaping how AECO (Architecture, Engineering, Construction, and Owner) firms manage design details in a $12 trillion industry that has been underserved by technology. Its mission is to reduce the time and cost associated with developing construction details by centralizing and making searchable a firm's entire detail library, thus enabling better reuse of knowledge and faster design workflows[1][3][6].

Origin Story

Pirros was founded by Ari Baranian and Peter Johann, both former structural engineers who experienced firsthand the inefficiencies and frustrations of managing design details across multiple projects. Their background in structural engineering and their exposure to multiple design firms highlighted a persistent problem: firms often recreate the same details repeatedly because accessing past work is cumbersome and time-consuming. This insight led them to create Pirros as a solution to centralize and streamline detail management.

The company launched in the early 2020s, backed by institutional investors and notable industry veterans such as Autodesk’s Carl Bass. Early traction came from onboarding structural engineering and architectural firms eager to improve their design workflows and reduce redundant work. Their participation in Y Combinator’s Winter 2023 batch further validated their approach and accelerated growth[2][4][5][6].

Core Differentiators

• Integration with Industry Software: Pirros seamlessly integrates with Revit, AutoCAD, and Autodesk Construction Cloud, extracting details and metadata automatically to make them searchable without manual tagging[2][5].

• Machine Learning-Driven Organization: The platform uses machine learning to auto-categorize unstructured detail files, cluster similar design solutions, and suggest frequently used details for inclusion in customer libraries, enhancing discoverability and reuse[2].

• Centralized Detail Library: Unlike traditional file servers, Pirros offers a single cloud-hosted repository where all past project details are stored, indexed, and easily accessible, saving time and reducing errors[1][4].

• User Experience: The platform provides a Google-like search experience tailored to AEC professionals, allowing quick filtering and retrieval of relevant details, improving speed and ease of use[5].

• Focus on AECO Industry: Pirros is built by former engineers for engineers and architects, addressing a niche that has been largely overlooked by general software solutions[6].

Role in the Broader Tech Landscape

Pirros rides the wave of digital transformation in the AEC industry, which has historically lagged behind other sectors in adopting cloud-based and AI-driven tools. The timing is critical as construction firms increasingly seek to improve efficiency, reduce waste, and accelerate project timelines amid rising costs and labor shortages.

The platform addresses a fundamental pain point—knowledge reuse in design—that has broad implications for productivity and sustainability in construction. By enabling firms to leverage their accumulated design knowledge, Pirros helps reduce duplicated effort and errors, contributing to faster project delivery and cost savings.

Moreover, Pirros contributes to the growing ecosystem of specialized software solutions that integrate with dominant platforms like Autodesk Revit, fostering interoperability and a more connected digital construction environment[1][2][3].

Quick Take & Future Outlook

Looking ahead, Pirros is well-positioned to expand its footprint within the AEC industry by deepening integrations, enhancing AI capabilities for smarter recommendations, and scaling its user base. As the construction sector continues to embrace digital tools, Pirros could evolve into the “GitHub for construction details,” becoming the standard system of record for design knowledge management.

Future trends shaping its journey include increased adoption of cloud collaboration, AI-driven design automation, and the push for sustainability through smarter resource use. Pirros’ influence may grow beyond detail management to become a critical enabler of digital workflows that improve quality and reduce waste in construction projects globally.

In sum, Pirros is transforming a traditionally manual and fragmented process into a streamlined, searchable, and reusable knowledge system, unlocking significant value for AEC firms and the broader construction ecosystem[1][2][5][6].
