Mini Business Ideas is a free directory of 526 small business ideas and 40 guides for people starting their first business. Most business idea lists are 50 one-liners. Mini Business Ideas treats an idea as useful only if you can judge it, so every entry has the same structured spec sheet: a realistic startup cost for a lean launch, including tools, equipment, basic legal setup and first marketing; what a solo founder or small team commonly earns after about 12 months of consistent work; how long it usually takes to reach the first revenue; a step-by-step plan to land the first customer; and a 7-day validation test you can run before spending real money. The income figures are ranges, not promises, and the site says plainly that plenty of businesses earn less. You can browse ideas by category, budget and location, or take a 5-question quiz to narrow them down. The site also has free tools including a business idea generator, a business name generator, a startup cost calculator and a profit margin calculator. Everything is free to read, there is no sign-up wall, and the ideas are updated regularly.
