This startup says it's made ChatGPT for construction sites. Read the pitch deck it used to raise $40 million.

A startup based in New York has successfully secured $40 million in funding to develop an AI solution aimed at streamlining administrative tasks within the construction sector. Known as Trunk Tools, the company specializes in converting unstructured data from the construction industry—such as documents, blueprints, and project schedules—into organized datasets for its AI systems. Construction professionals can interact with the AI using straightforward language, asking questions like, "Does this door require electricity?" The AI responds with answers and cites the relevant source material. "It's essentially a ChatGPT tailored for your job site," shared CEO Sarah Buchner in an interview with Business Insider. Over the past year and a half, Trunk Tools has introduced AI agents capable of autonomously managing comprehensive workflows, including scheduling and project tracking. Buchner noted that the company has developed specialized large language models tailored to the construction field, as generic AI often struggles with industry-specific data. "We constructed multiple models from the ground up using construction drawings and room boundaries," she explained. The company primarily offers its software through a subscription model, but some of its latest AI agents are billed based on business outcomes. Among its clients are major construction firms like Suffolk Construction, Gilbane, and DPR Construction. With a team of 60, Trunk Tools operates in both the United States and Canada. Buchner's journey began at the age of 12, working as a carpenter alongside her father in a small Austrian village. She climbed the ranks in the construction industry, eventually becoming a group leader, developing a construction safety app, and earning a Ph.D. in civil engineering and data science. She likened Trunk Tools' approach of embedding AI specialists within client organizations to the methods used by Palantir for promoting behavioral change through engineering. The recent $40 million Series B funding round was led by Insight Partners, with additional contributions from Redpoint Ventures, Innovation Endeavors, Stepstone, Liberty Mutual Strategic Ventures, and Prudence. This latest investment brings the company's total funding to $70 million, following a $20 million Series A round raised in 2024. Looking ahead, Buchner indicated that the startup plans to allocate half of this new capital toward product development and the other half to enhancing its market strategy. An exclusive look at the pitch deck used to secure this funding reveals the ambitious plans Trunk Tools has in store for the industry.
