Why systematic moat investing?

01

Economic Moats Compound

The best businesses become harder to compete with over time. Pricing power, switching costs, and network effects strengthen as the business scales, delivering above-market returns on capital for decades.

02

AI Rewrites the Playbook

Most competitive advantages are AI-vulnerable. We weight proprietary data, regulatory lock-in, and network effects 60% more heavily — the moats AI cannot replicate or destroy.

03

Concentration Beats Diversification

Owning 500 companies means funding mediocrity at scale. 25 high-conviction positions, each earning its place by scoring ≥75/100, concentrate capital where it compounds fastest.

Not all moats survive the AI era

Every business is scored across 10 competitive advantages. Five are AI-resilient (60% of the score) because AI cannot replicate them; five are AI-vulnerable (40%) because intelligent agents can increasingly substitute for them. Each moat is rated strong (100) · intact (75) · weakened (50) · destroyed (10).

Network Effects

Value compounds with every new participant

w=15

Following Metcalfe's Law, value scales with the square of participants. Every new user makes the network more valuable for all existing users — an enormous structural disadvantage for any challenger.

Proprietary Data

Private, compounding data flywheels

w=15

Data that accumulates privately over time and cannot be purchased or replicated. The longer the company operates, the harder it becomes to catch up. Think HealthKit biometrics, Palantir's classified datasets, or Visa's transaction graph.

System of Record

The authoritative source of truth

w=12

The company's data store is the canonical reference all downstream systems defer to. Replacing it requires migrating years of history and retraining every workflow built on top — so customers never voluntarily leave.

Regulatory Lock-In

Government licences, certifications & mandates

w=10

Advantages granted by law: FDA approvals, financial licences, index inclusion, spectrum rights. These cannot be automated away; the certification process itself is the moat.

Transaction Embedding

Sitting inside the payment layer

w=8

The business is embedded directly in the financial flow of every transaction. Removing it requires rebuilding critical infrastructure — not just switching a preference.

Business Logic

Embedded operational workflows

w=14

The software encodes years of accumulated business rules that employees rely on daily. While this creates significant switching costs today, AI can increasingly model and reproduce business logic, gradually eroding the cost of migration.

SAP ERP configurationsMDM device policiesLegacy COBOL systems

Bundling

Value from combining complementary products

w=10

Multiple products packaged together create convenience that point solutions can't match. AI-driven software commoditises features rapidly, making it easier for focused challengers to replicate any single element.

Learned Interfaces

Fluency built through years of UI habit

w=8

Users invest time mastering a specific interface — keyboard shortcuts, mental models, workflows. AI agents increasingly abstract away the interface layer, letting users command outcomes without learning a specific UI.

macOS / iOS UXFinal Cut ProAdobe Creative Suite

Talent Scarcity

Rare human expertise as competitive advantage

w=5

The business depends on a small pool of specialists whose skills are hard to find. AI augments and in some domains replaces highly skilled human work, compressing the scarcity premium over time.

Public Data Access

Privileged access to publicly available information

w=3

The company has a head-start aggregating data that is technically public but expensive to compile. AI web-crawlers and LLMs rapidly close this gap by training on the same underlying sources.

Each moat is rated strong (100) · intact (75) · weakened (50) · destroyed (10). N/A moats are excluded and weight redistributed within the group. A breadth bonus of +1 to +4 rewards businesses with more applicable moats, producing the Moat Score (40% of composite).
