Trunk Tools, Inc.

Trunk Tools, Inc. builds an AI platform for the construction industry, a sector it estimates at $13 trillion. The company's systems manage project information, answer questions drawn directly from specifications, RFIs, drawings and contracts, automate submittal review, and streamline workflows for construction professionals. Its work sits at the intersection of several demanding disciplines: artificial intelligence, AI agents, natural language document question answering, document automation, data science and civil engineering.

Two products define the current technical surface. TrunkText returns answers sourced from project documents in under 30 seconds. TrunkSubmittal automatically reviews 90% of submittals, catching discrepancies before they translate into costly rework. Deployed across more than 500 jobsites and construction volumes exceeding $50 billion, the platform is trusted by industry leaders including Gilbane, Suffolk, Haskell and AMLI. The company has raised $70 million to date.

The engineering philosophy is field-first. Intelligent agents are designed to augment human capability rather than replace workers, with a stated mission of ensuring the right information reaches the right people at the right time. Deep construction expertise is treated as a first-class requirement: the company was founded by Dr. Sarah Buchner, who began as a carpenter at the age of 12 in Austria before earning a PhD in Civil Engineering and Data Science.
