Proceed with Caution

Big Market,
Thin Moat

Large TAM but incumbents catch up fast. Only viable with exceptional distribution advantage or unique dataset.

AI-Powered CRM / Sales Automation

Horizontal

Risk: Salesforce Agentforce, HubSpot AI absorb this in 12–18 months. Only works with proprietary data angle.

SMB Finance & Accounting Automation

Office of CFO

Risk: Intuit, SAP, and Xero all moving aggressively. Viable only in underserved geographies or highly specific niches.

AI Marketing Content Generation

Horizontal

Risk: Commoditized rapidly by foundation model providers. Runway measured in months, not years.

Vertical AI for Mid-Market Healthcare

Vertical

Opportunity: Large TAM. Risk: Epic, Oracle Health have distribution. Requires genuine clinical workflow depth to survive.

Build Here

Strong Market,
Durable Moat

Greenfield surface area, structural complexity keeps incumbents out, proprietary data compounds over time.

AI Governance & Model Audit Infrastructure

Compliance

Why now: Regulatory mandates accelerating globally. No incumbent owns this. Adversarial distance from AI vendors is a feature, not a bug.

Greenfield Vertical AI (Trades, Agriculture, Maritime)

Vertical

Why now: Horizontal platforms will never prioritize these. AI-native build cost is 10× lower. Domain expertise is the real barrier.

AI Agent Orchestration & Workflow OS

Infra

Why now: Multi-agent enterprise environments have no coordination layer. MuleSoft-equivalent for agentic AI. Deeply embedded once deployed.

Non-Tech Industry Data Infrastructure

Data

Why now: Manufacturing, logistics, agriculture data environments are incompatible with Snowflake/Databricks. Bespoke build cost has collapsed with AI tooling.

Avoid

Crowded Market,
Commoditizing Fast

Incumbents are well-resourced, AI is eroding differentiation, and foundation models are absorbing the value layer.

Horizontal AI Copilots / Wrappers

Horizontal

Why not: OpenAI, Anthropic, Google absorb capability within a product cycle. No proprietary data, no lock-in, no path to Series B.

Standalone Social Media Management

CRM / CX

Why not: Sprout Social at -76% LTM tells the story. Salesforce / HubSpot absorb this as a feature. No standalone future.

Generic Document / E-Signature SaaS

Horizontal

Why not: Docusign is defending aggressively at commodity pricing. Adobe Sign bundled. No new entrant can build a business here.

"AI-Powered" [Existing SaaS Category]

Horizontal

Why not: The graveyard of 2022–2024 cohort funding. Incumbents ship the same feature in 18 months. This is an acqui-hire outcome at best.

Niche but Viable

Smaller Market,
Real Defensibility

Not venture-scale on their own, but strong acquisition targets or durable cash flow businesses with the right capital structure.

AI-Native Billing & Pricing for Agentic SaaS

Office of CFO

Why viable: Per-seat model is breaking down. Usage-based and outcome-based billing requires entirely new infrastructure. Real switching costs once embedded.

Specialty Manufacturing Workflow OS

Vertical

Why viable: Too small for SAP to prioritize, too complex for generic AI tools. Founder domain expertise creates genuine 10-year moat in a specific sub-vertical.

AI-Native Law Firm / Accounting Practice OS

Professional Svcs

Why viable: Billable-hour model is structurally disrupted. Existing LegalTech / FinTech too slow. Requires deep industry credibility to sell but extremely sticky.

Municipal / Sub-Tyler GovTech

GovTech

Why viable: Tyler Technologies ends at a certain market size. Smaller municipalities are structurally underserved and have 0% churn once deployed.

The Core Thesis

Horizontal AI application layer is largely captured. Real opportunity lives in vertical depth, regulatory complexity, and coordination infrastructure — areas where domain expertise is the real barrier, not engineering talent.

The Structural Advantage

10×

Reduction in build cost with AI tooling means sub-$50K ACV verticals that were previously uneconomical are now viable markets for a lean team with domain credibility.

The Unavoidable Risk

Commoditization speed is brutal. Any pure software capability without proprietary data or deep integration lock-in gets replicated by foundation model providers within 12–18 months. The clock starts at launch.
