What problem does it solve?

Many founders hold a revenue target without walking the numbers backward to see what it actually requires; this Skill converts a high-level revenue goal into concrete customer, funnel, and audience metrics so you can tell if the plan is realistic or off by orders of magnitude.

Core Features & Use Cases

• Stepwise funnel modeling: Converts an annual revenue target to monthly revenue, required paying customers, free/trial user counts, and total audience reach.
• Gap analysis & sensitivity: Compares current growth to required growth, quantifies X-fold gaps, and tests levers like pricing, conversion, premium tiers, and paid acquisition.
• Scenario stress tests: Generates base, conservative, exceptional, and worst-case outcomes and highlights which assumptions matter most.
• Use case: Evaluate whether a $1M ARR target at a given price point is achievable in 12 months given current customers and organic growth rates.

Quick Start

Provide your revenue target and timeline, your price or average revenue per customer, and current customers or growth rate and ask me to build a back-of-napkin funnel model.
