Articulate

Articulate is a San Francisco, California-based software company that develops business-to-business platforms designed to automatically execute clash detection within complex construction drawings. The proprietary technology enables architecture, engineering, and construction professionals to systematically identify structural, mechanical, and architectural conflicts prior to the physical building phase. By utilizing this automated system, project management teams can mitigate costly design errors and minimize necessary rework throughout the commercial real estate development lifecycle. Operating with a current headcount of two employees, the early-stage enterprise focuses on delivering specialized software licensing solutions directly to commercial design firms and general contractors. Although specific financial metrics and initial customer deployments remain undisclosed, the platform specifically targets the broader architecture, engineering, and construction sectors to streamline pre-construction planning workflows. Articulate was officially founded in 2025 by entrepreneurs Blake Passe and Milind Sagaram.

High-Level Overview

Articulate (the construction AI startup) is an AI-driven platform designed to automatically detect clashes and discrepancies in construction and solar project drawings before construction begins, helping contractors avoid costly rework, delays, and coordination errors. It generates Requests for Information (RFIs) and streamlines communication and procurement processes, significantly reducing the $177 billion annual loss in the US construction industry due to rework. Its long-term vision is to create an intelligent system that can generate safe, buildable, and code-compliant building designs from natural language prompts, drastically shortening pre-construction timelines from months to minutes[1][4].

For an investment firm, Articulate would represent a mission to leverage AI to transform construction workflows, focusing on sectors like construction technology and solar energy. Its investment philosophy would likely emphasize AI-driven automation and efficiency gains in traditionally manual industries. The startup impacts the ecosystem by introducing cutting-edge AI applications to construction, a sector ripe for digital transformation, potentially inspiring further innovation and investment in construction tech.

For the portfolio company perspective, Articulate builds an AI-powered clash detection and design validation product serving construction and solar contractors. It solves the problem of costly design errors and project delays by catching issues early in the design phase. The company shows strong growth momentum, having recently emerged from Y Combinator’s Fall 2025 batch and raising initial funding, positioning itself at the forefront of AI adoption in construction[1][4].

Origin Story

Articulate was founded in 2025 in San Francisco, emerging from Y Combinator’s Fall 2025 cohort. Its founder, Blake, has a background in AI research at Northrop Grumman and the Mayo Clinic AI Lab, with expertise in quantized large language models and prior experience developing popular AI-driven apps. Growing up in a small Minnesota town with many friends in construction, Blake was personally aware of the inefficiencies and costly errors in construction drawings, which inspired the creation of Articulate. Early traction includes successful participation in Y Combinator and initial funding rounds, validating the product’s potential to disrupt construction workflows[1][4].

Role in the Broader Tech Landscape

Articulate rides the wave of AI-driven automation and digital transformation in the construction industry, a sector traditionally slow to adopt new technologies. The timing is critical as construction projects increasingly demand faster, more accurate design validation to reduce costs and meet sustainability goals. Market forces such as rising labor costs, supply chain complexities, and the push for green energy installations (solar) favor solutions that improve efficiency and reduce errors. By integrating AI into design clash detection and project communication, Articulate not only reduces waste but also sets a precedent for AI’s role in construction, potentially accelerating broader adoption of intelligent automation in the built environment[1].

Quick Take & Future Outlook

Articulate is poised to significantly impact construction project management by reducing costly errors and delays through AI-powered design validation. The next steps likely involve scaling its platform, expanding beyond clash detection to full design generation, and deepening integrations with construction workflows. Trends shaping its journey include the growing adoption of AI in industrial applications, increased demand for sustainable and efficient building practices, and the digitization of construction processes. As Articulate evolves, it could become a foundational tool in construction tech, transforming how buildings are designed and constructed, and influencing the broader ecosystem by demonstrating AI’s tangible ROI in heavy industry[1][4].
