May 5 Finance Note: Unit Economics Before the Fundraise
A plain-English look at contribution margin, payback, churn, retention, and why investors ask for the math behind growth.
Unit economics explain whether growth is creating value or simply buying activity. Founders should know what it costs to acquire and serve a customer, what revenue remains after direct costs, and how long it takes to recover acquisition spend.
For early startups, the numbers may be rough. That is acceptable if the assumptions are explicit and improving. Investors mainly want to see that the founder understands the levers: pricing, gross margin, churn, expansion, support cost, and sales cycle.
Regional founders can use capital efficiency as a strength. Lower operating costs help only when paired with revenue quality and retention proof.
