Moat

Core Rule

A SaaS moat is not a feature, a UI, a model wrapper, or "we will move fast."

A real moat must pass both tests:

1. Benefit: it creates higher customer value, lower cost, better retention, faster distribution, or better margins.
2. Barrier: competitors cannot cheaply copy, neutralize, or bypass it.

For SaaS, judge moats by their effect on profitability:

• Higher willingness to pay.
• Lower churn and higher gross revenue retention.
• Expansion revenue and stronger net revenue retention.
• Lower CAC or faster CAC payback.
• Higher gross margin or lower cost-to-serve.
• Stronger pricing power.
• Lower support/onboarding drag over time.
• More durable distribution.

Operating Workflow

1. Identify the SaaS idea, customer, buyer, and workflow.
2. Identify the profit engine:
   • Pricing model.
   • Gross margin drivers.
   • Cost-to-serve.
   • Acquisition channel.
   • Retention and expansion mechanism.
3. Identify candidate moat types:
   • Switching costs.
   • Workflow/system-of-record depth.
   • Network effects.
   • Data advantage.
   • Integration depth.
   • Distribution advantage.
   • Brand/trust.
   • Scale or cost advantage.
   • Process power.
   • Ecosystem, marketplace, partner, reseller, or white-label channel.
   • Compliance, regulatory, procurement, or operational trust.
4. Test each candidate moat:
   • What customer behavior proves it?
   • What product function creates it?
   • What business metric should improve?
   • What must compound over time?
   • How would a competitor attack it?
   • Is it a real barrier or only temporary differentiation?
5. Convert the moat into product requirements:
   • Data model.
   • Dashboard/workflow.
   • Integrations.
   • Collaboration.
   • Permissions.
   • Audit/history.
   • Automation.
   • Sharing.
   • Billing/entitlements.
   • Analytics.
6. Output a moat plan with proof metrics and build sequence.

Default Stance

Be skeptical.

Treat these as weak moat claims unless proven:

• "We use AI."
• "We have data."
• "We have a better UI."
• "We are first."
• "We will ship faster."
• "Customers will not switch because migration is annoying."
• "We have many features."
• "We will build a community later."
• "Competitors are old."

Push every moat claim toward a measurable structural barrier.

Reference Routing

Load only what is needed:

• references/moat-framework.md: moat theory, SaaS translation, moat types, false moats, and how to turn moat claims into product functions.
• references/profitability-model.md: SaaS metrics and business-model checks for NRR, GRR, CAC payback, gross margin, Rule of 40/Rule of X, pricing power, cost-to-serve, and margin protection.
• references/product-function-patterns.md: practical SaaS product patterns that create moat through workflow depth, data loops, integrations, collaboration, compliance, marketplace, reseller, white-label, and AI workflows.
• references/review-scorecard.md: structured review template, scoring rubric, red flags, questions, and implementation outputs.
• references/research-sources.md: source map and research takeaways used to shape this skill.

If used with saas-kit, let saas-kit drive spec approval and use this skill to add moat/profitability requirements to Goal, Scope, Requirements, Backend, Database, APIs, UI/UX, Security, Testing, and Implementation Steps.

If used with saas-product-growth, use that skill for full SaaS component/growth coverage and this skill for defensibility, profit protection, and moat proof.

Output Shapes

For a SaaS idea:

• Moat thesis.
• Customer value created.
• Business profit protected.
• Product functions that create the moat.
• Proof metrics.
• Competitor attack paths.
• Weak assumptions.
• MVP moat path.
• Production moat path.
• Scale moat path.

For an existing SaaS app:

• Real moats found.
• Claimed moats that are only features.
• Missing product functions needed to create defensibility.
• Profitability risks.
• Metrics to instrument.
• Prioritized build plan.

For implementation after approval:

• Build the smallest product function that strengthens a measurable moat.
• Avoid overbuilding enterprise friction unless it protects real revenue, retention, trust, or margin.
