Trunk Tools: The $40M AI Revolution Transforming Construction Sites

Trunk Tools has successfully raised $40 million in its Series B funding round, marking a significant milestone for the New York-based startup. The company specializes in developing AI agents tailored for the construction industry, effectively acting as a "ChatGPT for your job site."

How Trunk Tools is Changing the Game

• Custom AI Solutions: Trunk Tools transforms unstructured construction data—like documents, drawings, and schedules—into structured datasets. This enables workers to ask questions in plain language, such as "Does this door require electricity?" and receive accurate answers along with source materials.

• Autonomous Workflows: Over the past 18 months, the startup has introduced AI agents capable of handling entire workflows autonomously, including scheduling and project tracking.

• Tailored Large Language Models: Unlike general-purpose AI, Trunk Tools has developed custom models trained specifically on construction data, ensuring higher accuracy and relevance.

The Vision Behind Trunk Tools

Founded by Sarah Buchner, who started her career as a carpenter at age 12, Trunk Tools combines deep industry knowledge with cutting-edge technology. Buchner's journey from construction worker to CEO underscores her commitment to bridging the gap between traditional construction practices and modern AI solutions.

Funding and Future Plans

The $40 million Series B round was led by Insight Partners, with participation from Redpoint Ventures, Innovation Endeavors, and others. This brings Trunk Tools' total funding to $70 million. The fresh capital will be split between product development and go-to-market strategies, aiming to expand its footprint in the US and Canada.
