Trunk Tools, a North American construction technology startup, successfully raised $40M in a 2024 Series B round. Their pitch deck centers on the 'humanly impossible' task of managing construction data, citing that a single project can generate 3.6 million pages of documentation—three times the height of the building itself (Slide 3). The deck positions Trunk Tools as the market leader in a $13T global industry, specifically targeting the $4T spent on knowledge work (Slide 2). By integrating with legacy systems like Procore and Autodesk, the platform claims to automate 65.3% of administrative…

Trunk Tools Series B Teardown: The Rise of Vertical AI in Construction
Trunk Tools raised $40M in 2024 to tackle one of the most document-heavy industries on the planet. Their Series B deck is a masterclass in visualizing a 'hidden' problem—the sheer weight of paperwork that slows down multi-billion dollar infrastructure projects. While many AI decks focus on general productivity, Trunk Tools leans into 'Vertical AI,' arguing that construction requires specialized agents to handle its unique complexities.
Slide 1-2: The Macro Opportunity
The deck opens with a clear identification of the founder, Dr. Sarah Buchner, and immediately pivots to the market size. Slide 2 establishes the stakes: a $13T global industry. Crucially, they segment this into '$4T Knowledge Work.' This is a strategic move; by highlighting the knowledge work component, they define their Total Addressable Market (TAM) not by the physical buildings, but by the administrative friction required to build them. The claim 'And We Are the Market Leader' sets a confident tone for a Series B round.
Slide 3: Visualizing the 'Humanly Impossible'
Slide 3 is arguably the most effective slide in the deck. It uses a skyline visual to compare a 400 ft building to the 1,200 ft stack of paper generated by its construction. By quantifying the data—120,000 files, 3.6 million pages—they move the problem from an abstract annoyance to a physical impossibility. The tagline 'Humanly impossible' justifies the need for AI without needing to explain the technology first.
Slide 4: The Integration Layer
A common hurdle for construction tech is the fragmented software landscape. Slide 4 addresses this by showing Trunk Tools as the 'brain' sitting beneath existing giants. They list integrations with Autodesk Construction Cloud, Procore, Oracle P6, Box, SharePoint, Microsoft Project, and Egnyte. This slide reassures investors that Trunk Tools isn't trying to replace the industry's record-keeping systems, but rather to make them searchable and actionable through their AI agents: TrunkPrepare, TrunkSchedule, TrunkText, TrunkSubmittal, and TrunkStandard.
Slide 5: The Automation Breakdown
Slide 5 provides the 'meat' of the efficiency claim. It features a pie chart stating that 65.3% of work is automated. The breakdown is granular, which adds credibility. They identify Plan Discrepancy (16.3%) and RFIs (14.3%) as major areas of impact. By naming their specific agents alongside these metrics, they link product features directly to time-saving outcomes.
Slide 6-7: Product in Action
Slide 6 introduces 'TrunkDetect v1: TrunkSubmittal' with a video placeholder. This indicates a shift from theory to demonstration. Slide 7 (though not explicitly detailed in the text beyond the header) likely continues this product-led narrative, showing how the AI interacts with the unstructured data mentioned in the earlier slides.
Slide 8: The Thesis for Vertical AI
Slide 8 explains 'Why Construction Needs Vertical AI.' It identifies four pillars: Data & Document Complexity, Skilled Labor Shortage, Siloed Systems & Slow Decisions, and High Stakes & Low Margins. This slide serves as the 'Why Now?' and 'Why This Industry?' argument. It frames the labor shortage not just as a lack of boots on the ground, but as a lack of capacity to handle the increasing administrative burden.
Slide 9: Brand Equity and Leadership
Slide 9 focuses on 'Invaluable Brand Equity.' It features a collage of media appearances, awards, and conference speaking engagements. Dr. Sarah Buchner is highlighted as a 'Top 25 Newsmaker.' For a Series B, showing that the founder is a recognized thought leader in a traditional industry like construction is a significant de-risking factor for investors.
Slide 10: Real World Impact
The final content slide (Slide 10) delivers the hard metrics. It claims a construction volume of over $50 Billion. The most compelling figures are the '25 hrs/week saved per Project Manager' and the '$375K-$750K weekly time value reclaimed.' These are the numbers that justify a $40M check. The mention of '87% Verified field accuracy' is also vital, as AI hallucinations are a primary concern in high-stakes environments like construction sites.
Slide 11-19: The Closing
The deck concludes with a contact slide featuring a QR code and the hashtag #LetBuildersBuild. The remaining slides in the 19-slide count likely included appendix data, case studies, or deeper technical dives that were not part of the primary narrative flow provided in the images.
What Works in the Trunk Tools Deck
The Scale Comparison: Using the height of a building to represent the volume of paperwork (Slide 3) is a brilliant way to make a boring problem (data management) feel urgent and massive.
Granular Automation Metrics: Instead of saying 'we save time,' Slide 5 breaks it down into specific categories like 'Plan Discrepancy' and 'Meeting Preparation.' This shows a deep understanding of the customer's daily workflow.
Integration Focus: By showing logos of Procore and Autodesk (Slide 4), they position themselves as a 'must-have' layer on top of existing expensive investments, rather than a 'rip and replace' risk.
What is Missing from the Trunk Tools Deck
Detailed Unit Economics: The deck is heavy on customer ROI but light on company ROI. There is no mention of Customer Acquisition Cost (CAC), Lifetime Value (LTV), or specific pricing tiers.
Competitive Landscape: While they claim to be the 'Market Leader,' the deck does not show a competitive matrix or explain how they differ from other construction AI startups or the AI modules being built natively by Procore and Autodesk.
The Full Team: The deck is very founder-centric. While Dr. Buchner has impressive credentials, a $40M Series B usually requires showing the strength of the broader executive team (CTO, Head of Sales, etc.).
What Founders Should Copy
The 'Humanly Impossible' Frame: If your startup handles large amounts of data, find a way to visualize it that makes the manual alternative look ridiculous. The '3x building height' metric is the '1,000 songs in your pocket' moment for construction tech.
Vertical Specificity: Trunk Tools doesn't talk about 'LLMs' or 'Generative AI' in a vacuum. They talk about 'RFIs,' 'Submittals,' and 'Change Orders.' Founders should use the specific vocabulary of their target industry to build immediate trust.
Outcome-Based Headlines: Every slide header in this deck tells a story. From 'Real Impact' to 'Invaluable Brand Equity,' the headers ensure that even a skim-reader gets the core message of the company's value proposition.
