$23k/month with excel fomulas, crazy! | Starter Story

This episode of Starter Story breaks down how a simple, almost absurdly straightforward website—Excel FormulaBot—generates $23,000 a month. The core insight is not about complex technology or marketing funnels, but about identifying a massive, painful problem for a huge audience and solving it with the absolute minimum viable product. The conversation walks through the mechanics, the psychology of the paying user, and the conditions that allowed a solo founder to hit product-market fit within minutes of launch.

The Problem: The Billion-Person Niche

The episode opens with a striking number: over a billion people use Microsoft Excel. The founder of Excel FormulaBot recognized that a significant portion of these users, from accountants to project managers to students, share a common frustration: writing complex formulas. The product is deceptively simple. You type a plain-English question like "how do I get the average of column A," and the website, powered by an LLM, spits out the exact formula.
