The Problem
Without a model, marketing budgets are based on gut feelings, last year's numbers, or competitor mimicry.
You pour money into channels without knowing your unit economics. Is that $50 CAC profitable? Without LTV context, you are flying blind.
What happens if CAC goes up 20%? Or if you expand to a new channel? Without modeling tools, every budget decision is a gut call.
Operating across markets with different currencies makes it nearly impossible to compare unit economics in a spreadsheet.
