Trunk Tools raises $40 million

Trunk Tools, a New York-based startup offering an AI-driven platform for the construction industry, announced a $40 million Series B funding round led by Insight Partners with participation from Redpoint Ventures, Innovation Endeavors, Stepstone, Liberty Mutual Strategic Ventures, and Prudence. The new investment brings total funding to date to $70 million.

Founded in 2021, Trunk Tools uses AI to organize and provide insight into the millions of documents–drawings, specs, RFIs, schedules, and submittals–generated throughout the lifecycle of a project. The platform enables teams to ask natural-language questions and receive “instant, accurate, and actionable answers” sourced from the relevant information.

The company is already deployed on hundreds of construction projects and has scaled revenue 5x over the past six months.

“Construction is the backbone of our global economy and daily life, yet the industry is still bogged down by outdated tools, fragmented systems, and overwhelming bureaucracy. We built Trunk Tools to eliminate the guesswork. General-purpose AI simply isn’t advanced enough for an industry built on proprietary data and complex workflows. This new round of funding gives us the resources to bring vertically tailored AI reasoning agents to every job site.” – Trunk Tools CEO Dr. Sarah Buchner.

“Trunk Tools is helping define a new category of AI with its construction platform. Project-level information in the construction industry lives in multiple siloed systems, and accessing that data is a time-consuming and error-prone process for field teams who need it in real time. Sarah and her team of construction tech experts are applying their deep industry experience to address this with modular AI agents.” – Jeff Horing, Co-founder and Managing Director at Insight Partners.
