Mini Business Ideas is a free directory of 526 small business ideas and 40 guides for people starting their first business. Instead of one-line lists, every idea has the same spec sheet: a realistic startup cost, what a solo founder commonly earns after about 12 months, a step-by-step launch plan and a 7-day validation test. You can browse by category, budget or location, take a 5-question quiz, and use free tools such as a startup cost calculator, a profit margin calculator and a business name generator. The income figures are ranges, not promises, and the site says plainly that plenty of businesses earn less. Everything is free to read, and there is no sign-up wall.
