AI Disruption of Legacy Industries: Where Founders Should Be Building

$258.7 billion of AI venture capital is chasing disruption โ€” but it's concentrated in the wrong places. The biggest opportunities are in the industries founders aren't yet targeting.

๐Ÿ“… February 27, 2026 ๐Ÿ”ญ Galileo Research

Executive Summary

AI captured 61% of all global venture capital in 2025 โ€” $258.7 billion out of $427.1 billion total.[1] But this capital is heavily concentrated in a few sectors (legal, healthcare, fintech) while industries with equal or greater disruption potential remain founder-starved. This report maps 12 legacy industries by AI vulnerability, cross-references with startup activity, and identifies where the gap between disruption potential and founder attention creates the best seed-stage opportunities.

Bottom line: Seed capital should flow to vertical AI companies targeting high-vulnerability, low-founder-activity industries โ€” particularly government services, construction, and agriculture. These sectors have the structural characteristics (fragmented, paper-heavy, regulated, labor-intensive) that make them most susceptible to AI disruption, but founders haven't shown up yet. The window is open.

1. The Disruption Vulnerability Framework

Not all industries are equally vulnerable to AI. The factors that predict disruption potential are structural, not just technical:

A critical insight from Goldman Sachs: despite $258.7 billion in AI venture capital in 2025, AI's contribution to U.S. GDP growth was "basically zero."[3] Over 80% of companies report no productivity gains from AI so far. This isn't a failure of AI โ€” it's a failure of application. Capital has flowed to horizontal tools and foundation models while the vertical application layer โ€” where AI actually touches industry workflows โ€” remains underdeveloped.

TrueBridge Capital's analysis (Forbes, Feb 2026) confirms the shift: "If 2024 and 2025 were about foundation models, 2026 is increasingly about application-layer execution."[4] Vertical AI companies like Harvey (legal) and Abridge (healthcare) are demonstrating growth curves dramatically compressed compared to prior software generations โ€” reaching hundreds of millions in ARR within 2โ€“3 years of launch.

2. Sector Vulnerability Ranking

Industry AI Displacement Risk Market Size Current AI Penetration Founder Activity Gap Score
Office & Admin 90%[5] $550B (US BPO) High โ€” horizontal tools (Copilot, etc.) High Low
Finance & Accounting 84%[5] $624B (global accounting) Medium โ€” Big Four investing $10B+[6] High Low
Retail & Customer Support 82%[5] $5.5T (US retail) High โ€” chatbots, personalization ubiquitous Very High Low
Legal Services 75%[5] $1.1T (global) Medium-High โ€” $4.3B legaltech funding in 2025[2] Very High Low
Insurance 72% $6.4T (global premiums) Medium โ€” insurtech โ†’ $239B by 2033[7] High Medium
Government / Public Sector 68% $8.9T (US gov spending) Very Low โ€” pilot projects only[8] Very Low โ˜… Very High
Construction 46%[5] $13T (global) Very Low โ€” <10% meaningful adoption[7] Low โ˜… Very High
Agriculture 52% $3.5T (global ag) Low โ€” $7.8B digital ag market[9] Low-Medium โ˜… High
Logistics & Supply Chain 65% $9.5T (global logistics) Medium โ€” Flexport, project44, etc. Medium Medium
Healthcare (clinical) 55% $4.5T (US) Medium โ€” Abridge, Ambience, Nabla Very High Low
Education 60% $7.3T (global) Low-Medium Medium Medium
Energy & Utilities 45% $8T+ (global energy) Low โ€” Schneider/NVIDIA digital twins[7] Low โ˜… High
Reading the table: "Gap Score" measures the mismatch between disruption potential and current founder/VC activity. โ˜… High and โ˜… Very High gaps represent the most attractive entry points for seed investors โ€” large markets with structural vulnerability but insufficient startup coverage.

Note on displacement scores: The FAIR Framework scores (marked with citations) measure job-level displacement risk โ€” how much competitive pressure AI creates. A 46% displacement score for construction doesn't mean 46% of the industry will be automated. It means nearly half of construction work processes will be fundamentally reshaped by AI, creating massive demand for tools that help the industry adapt.[5]

3. The Gap Zones: Where Founders Aren't Building

๐Ÿ›๏ธ Government & Public Sector โ€” The Largest Gap

The U.S. government alone spends $8.9 trillion annually. State and local governments process millions of permits, licenses, benefits applications, and compliance reviews โ€” overwhelmingly through manual, paper-based workflows. AI adoption is in early pilot stages at best.[8]

Why it's underserved: Government procurement is slow, opaque, and relationship-driven. Sales cycles are 12โ€“24 months. Founders prefer faster-moving enterprise markets. But the structural characteristics scream disruption: massive data volumes, repetitive rule-based decisions, chronic staffing shortages, and immense political pressure to modernize.

Who's building: Almost nobody at scale. Polimorphic ($18.6M Series A, 2025) sells AI chatbots and permitting tech to local governments.[8] EffiGov (YC) is building an "AI OS for local governments" starting with 311 call operators.[10] Deloitte published a major GovTech Trends 2026 report focused on "digital agents" for citizen services.[11] But compared to the ~$4.3B flowing into legaltech, government AI is essentially unfunded.

The opportunity:

๐Ÿ—๏ธ Construction โ€” The Physical-World Frontier

Construction is the world's largest industry at $13 trillion globally, and one of the least digitized. Meaningful AI adoption is below 10%.[7] AI in construction is expected to grow from $1.3 billion in 2022 to $13.5 billion by 2030 โ€” a 10x expansion that's still a fraction of the industry's size.[12]

Why it's underserved: Construction data is messy, fragmented, and physical-world. Unlike legal or finance, you can't just throw an LLM at a corpus of text. You need integration with sensors, drones, BIM models, project management tools, and safety systems. The technical bar is higher, and the customer base (general contractors, trade subcontractors) is notoriously resistant to new technology.

The opportunity:

๐ŸŒพ Agriculture โ€” Scale Meets Complexity

The global agricultural market is $3.5 trillion, with a digital agriculture market of $7.8 billion growing at 10.4% CAGR to $17.2 billion by 2033.[9] AI in agriculture specifically is projected to reach $8.5 billion by 2030.[13] But adoption remains concentrated in large-scale operations, leaving the vast majority of the world's 570 million farms untouched.

Why the gap matters: The AI-as-a-Service model is finally making precision agriculture accessible to smaller farms via cloud-based subscriptions rather than heavy hardware investments.[13] This is an inflection point โ€” the technical capability to serve the long tail of agriculture is arriving, but the startups to capture it haven't scaled.

โšก Energy & Utilities โ€” Resilience as Competitive Advantage

The Heathrow substation fire (ยฃ40M cost) and the Iberian Peninsula blackout (โ‚ฌ1.6B lost economic output) in recent months have laid bare how fragile energy infrastructure is.[7] Every $1 invested in AI-powered resilience and disaster preparedness saves $13 in post-event costs.[7]

Schneider Electric's partnership with NVIDIA on AI-driven digital twins for energy management is a leading indicator, but the vast majority of utilities โ€” particularly smaller municipal and cooperative utilities โ€” have no AI capability whatsoever. This is structurally similar to the government sector: large, slow-moving incumbents with immense data and clear ROI for AI, but a procurement culture that repels startups.

4. The Crowded Lanes: Where Founders Are Already Swarming

For context, here's where capital is concentrated โ€” these are validated categories, but entry windows are compressing:

Legal (Saturating)

Harvey: $800M+ raised, $8B valuation, $100M ARR, serves 8 of 10 top-grossing US law firms.[2][14] Clio: $500M Series G, $5B valuation.[15] Total legaltech funding hit $4.3B across 356 deals in 2025, with AI-powered tools driving 70% of investment.[2] The growth is real โ€” Harvey reached $100M ARR in roughly two years โ€” but the top of the market is claimed. Seed opportunities exist in legal sub-verticals (regulatory compliance, contract lifecycle for mid-market, litigation analytics) but not in general-purpose legal AI.

Healthcare AI (Crowded, Specialty Gaps Remain)

Clinical documentation (Abridge, Ambience, Nabla) and medical imaging are well-funded categories. But specific clinical specialties, revenue cycle management for smaller practices, and clinical trial operations remain less contested. Jack's defense and deep-tech focus may find overlap in healthcare AI for military/VA applications.

Insurance (Maturing)

Insurtech market projected to reach $239.2 billion by 2033 at 27% CAGR.[7] Agentic AI in underwriting and claims is becoming standard โ€” by mid-2025, industry publications documented real-world deployment in claims processing, fraud detection, and underwriting.[16] FurtherAI ($25M Series A from a16z) is automating underwriting, claims, and compliance in the $7T insurance industry. Seed opportunities remain in specialty lines, parametric insurance, and the intersection of AI + climate risk.

Accounting & Tax (Early-Crowding)

The Big Four are collectively investing $10B+ in AI (Deloitte $3B by 2030, KPMG $5B, PwC $1.5B).[6] Thomson Reuters launched agentic AI for tax and audit workflows in December 2025.[17] 64% of accounting firms plan AI investments in 2025, up from 57% in 2024.[6] But the mid-market and SMB segments remain underserved โ€” the Big Four investments serve enterprise, leaving millions of smaller firms without AI-native tools.

5. Accelerator Batch Composition: Where Founders Are Actually Building

The best leading indicator of where startups will cluster in 18 months is where accelerator batches are concentrated today. We analyzed recent cohorts from YC, Neo, and HF0 to map founder activity by vertical.

Y Combinator (W25 + S25)

YC's recent batches represent the single largest dataset of early-stage founder intent. The pattern is unmistakable:

Metric W25 Batch S25 Batch Signal
Total companies ~155 ~160โ€“169 Steady at scale
AI-native / AI-centric ~90%[20] 88%[21] AI is table stakes, not differentiator
B2B / Enterprise ~80% 80โ€“85%[22] Consumer is out of fashion
Dev tools / Infrastructure ~30% ~30%[22] Picks-and-shovels crowding
Agentic AI ~50% 50%+[22] Agent verticalization is the dominant pattern
Defense / dual-use 5 companies Growing[21] Emerging but small
Government / GovTech 1โ€“2 (EffiGov, Permitify) "Least common"[22] โ˜… Massive gap
Construction 1 (Permitify โ€” straddles gov + construction) ~0 โ˜… Massive gap
Agriculture 1 (Red Barn Robotics) ~0 โ˜… Massive gap
Energy / Utilities ~0 ~0 โ˜… Massive gap
The critical datapoint: YC itself acknowledged that "education and government were least common" in the S25 batch.[22] When YC โ€” the single most sensitive barometer of founder intent โ€” says a category is underrepresented, it's a direct signal that the gap in our framework is real, not a measurement artifact.

Where YC founders are swarming: Dev tools (30%), AI copilots for sales/recruiting/finance (~20%), healthcare AI (~8%), fintech (~10%). The typical S25 company is "an AI agent that does [specific B2B task] for [specific persona]" โ€” vertical agentic AI applied to information-worker workflows. Almost no one is building for physical-world industries.

Neo (Ali Partovi)

Neo is smaller (12โ€“15 startups per cohort, <1% acceptance rate) but ultra-high-signal โ€” Partovi's track record includes Cursor ($30B valuation), Kalshi, and Bluesky.[23] Recent portfolio reveals:

Pattern: Neo's portfolio is heavily concentrated in fintech, healthcare AI, and developer tools โ€” the same crowded lanes as YC. Notable absences: zero construction, zero agriculture, zero energy, zero government. This is consistent with Neo's focus on "exceptional young technologists" โ€” founders who come from Big Tech and build for information-worker workflows they personally experienced. Physical-world industries don't attract this founder profile.

HF0 (Repeat Founders)

HF0 is the most selective accelerator (~15 teams per batch, <1% acceptance), focused on repeat founders with technical depth. Portfolio companies include:[24]

Pattern: HF0 is the only top accelerator with any meaningful physical-world representation. Roofer.com ($7.5M seed, Dallas) is genuinely AI-native construction โ€” using drones and AI for roofing inspections and estimates, not just a lead-gen marketplace with an AI veneer. Smartroof appears construction-adjacent but with less verifiable AI depth. Even so, HF0's dominant pattern remains dev tools and B2B software โ€” these physical-world companies are the exceptions that prove the rule.

The Accelerator Gap Map

Vertical YC (W25+S25) Neo HF0 Total Signal
Dev Tools / Infra ~95 companies Cursor + others Fileread, Delv Saturated
Fintech ~25 companies Moment Crossmint Crowded
Healthcare ~15 companies Anterior โ€” Competitive
Government 1โ€“2 companies โ€” โ€” โ˜… Empty
Construction 0โ€“1 companies โ€” Roofer, Smartroof โ˜… Nearly empty
Agriculture 1 company โ€” โ€” โ˜… Empty
Energy / Utilities 0 companies โ€” โ€” โ˜… Empty

6. Grassroots Launch Activity: Product Hunt & Hacker News

Accelerator batches show what institutional gatekeepers are funding. Product Hunt and Hacker News show what founders are independently choosing to build โ€” a grassroots signal of where energy and excitement concentrate.

Product Hunt: What's Launching

Product Hunt's top AI categories in 2025โ€“2026 reveal where indie founders and small teams are building:[25]

Hacker News: What's Being Discussed

HN front-page AI discussions in late 2025 / early 2026 are dominated by:

Conspicuously absent from HN discourse: AI for construction, agriculture, energy, government, manufacturing. These industries simply don't exist in the developer/founder community's consciousness. When they do appear, it's typically in the context of "AI winter" skepticism โ€” "AI hasn't actually changed anything in the real economy."

The attention arbitrage: Product Hunt and HN are proxies for where technical founder attention concentrates. That attention is overwhelmingly on information-worker tools โ€” because that's what technical founders themselves use daily. Physical-world industries suffer from a founder-experience gap: few YC/Neo/HF0 founders have ever worked in construction, agriculture, or local government. This creates a structural blind spot that will persist until domain-expert founders (not just technical founders) start building in these spaces โ€” or until someone creates the "Cursor for construction" narrative that makes these industries legible to the technical founder community.

Every red dot in the bottom-right (legal, finance, office/admin, retail) is a category where capital and founders have already arrived in force.

8. Where to Place Seed Bets

The Framework: High Gap Score + Jack's Thesis Overlap

Cross-referencing the gap analysis with Jack's investment thesis (AI, energy, deep-tech, defense, robotics), three categories offer the strongest fit:

Opportunity Why Now Ideal Founder Profile Estimated Entry Window
AI for Government Services DOGE-era political pressure to modernize; chronic staffing shortages; Deloitte GovTech 2026 signals enterprise readiness Ex-government + technical; understands procurement; patient with sales cycles 12โ€“18 months before category crowds
AI for Construction 10x growth trajectory ($1.3B โ†’ $13.5B); labor shortage crisis; infrastructure bill deployment creating demand Construction domain expert + ML; understands jobsite realities, not just software 18โ€“24 months; physical-world complexity creates natural moat
AI for Energy/Utility Resilience Recent infrastructure failures (Heathrow, Iberia); 13:1 resilience ROI; Jack's energy thesis alignment Energy sector operator + AI; understands grid dynamics, regulatory environment 12โ€“18 months; regulatory push accelerating
AI for Agriculture (SMB) AIaaS model makes precision ag accessible to smaller farms for first time; $8.5B market by 2030 Ag-tech domain expert; understands farmer behavior and seasonal cycles 24+ months; adoption is slow but inevitable

The Contrarian Bet: Physical-World AI

The consistent pattern across the highest-gap industries (government, construction, agriculture, energy) is that they involve physical-world complexity. Most AI capital has flowed to information-first industries โ€” legal, finance, healthcare documentation โ€” where the data is clean and digital.

2nd Order Physical-world AI is harder to build, which means it's harder to compete against. A legal AI startup faces the risk that OpenAI or Google ships a competitive feature in a model update. A construction AI startup that integrates with drones, BIM systems, project management tools, and safety hardware has a defensibility moat that model improvements can't easily replicate.

3rd Order Physical-world AI unlocks GDP growth that information-only AI can't. Goldman Sachs says AI has added "basically zero" to GDP so far.[3] That's because information-worker productivity gains are real but small in economic terms. The big GDP unlock comes when AI makes physical processes more efficient โ€” construction, manufacturing, agriculture, energy. The $7 trillion GDP boost Goldman predicted requires AI to reach the physical economy. The companies that bridge that gap will capture enormous value.

The seed investor's edge: VCs with patience and domain networks can access these high-gap sectors before the generalist capital arrives. Construction, government, and energy have long sales cycles that deter impatient capital โ€” which is exactly what creates durable early-mover advantage. By the time the sector heats up, well-positioned seed investments will have 18โ€“24 months of customer learnings, data, and workflow integration that later entrants can't replicate.
