Growth Strategy Simulator

How it works

The simulator runs three parallel channel models using the same budget, CAC, and churn inputs. Each channel has a base efficiency factor and a monthly compound rate. Paid-only runs at 1.0x base efficiency with no compounding: every dollar buys the same number of customers each month. SEO-heavy starts at 0.70x base efficiency but compounds at 5% per month, simulating the slow build of organic reach. Blended starts at 0.85x and compounds at 2% per month. For each month in the simulation, the model calculates a channel efficiency value as: base times (1 + compound rate) raised to the month index. New customers acquired that month equals the floor of (monthly budget times efficiency) divided by CAC. Active customers at end of month equals the floor of previous active customers times (1 minus churn rate), plus the new customers acquired. This means churn is applied before adding new customers, which is the conservative calculation. The simulation runs for up to 12 months (the default shown in the interface). MRR at any point is active customers multiplied by ACV. The key design insight is what the curves reveal over time. Paid-only grows linearly and stops the moment budget stops. SEO starts slower than paid but at 5% monthly compounding, efficiency is about 63% higher by month 12 than at month 1. That gap, visible in the chart, is the core argument for organic investment having a longer time horizon than most growth plans account for. The blended channel sits between the two, compounding more slowly but starting from a higher base than SEO. The numbers are illustrative, not predictive. Real CAC varies by month and channel maturity. Use the simulator to stress-test your assumptions, not to forecast revenue.
