Prompts to Use
Act as a financial analyst for startups. I need to understand my unit economics. My business is {business_description}. My average customer pays {average_price} per month. It costs me {cost_to_serve} to deliver the service per month. I spend {marketing_spend} to acquire one new customer. Calculate my Gross Margin, Customer Acquisition Cost (CAC), and Lifetime Value (LTV) assuming a 2-year average customer lifespan. Output the results in a simple markdown table and provide a 2-sentence summary of my business health.
