Bro makes $40K per month with such a simple website... | Starter Story

In 2021, a solo founder launched a tool called Bank Statement Converter. It does one thing: it converts bank statement PDFs into Excel or CSV files. Today, it generates $40,000 in monthly recurring revenue, has 75,000 total users, about 1,000 paying customers, and 40,000 monthly visitors. The product is a simple, single-purpose website that solves a narrow but painful problem for accountants, bookkeepers, and small business owners.

The Origin: Solving a Real, Boring Problem

The founder didn't set out to build a startup. He was working as a freelancer and doing his own bookkeeping. He kept receiving bank statements as PDFs and needed to get the data into a spreadsheet. Manually typing numbers from a PDF into Excel was tedious and error-prone. He looked for existing tools, found them either too expensive or too complicated, and decided to build a simple converter for himself.
