Mini Business Ideas is a free directory of 526 small business ideas and 40 guides for people starting their first business. Each idea has a structured spec sheet with a realistic startup cost, an income range for a solo founder or small team after about 12 months, a step-by-step plan to land the first customer, and a 7-day validation test. Income figures are ranges, not promises. Browse ideas by category, budget or location, or take a five-question quiz to narrow them down. Categories include AI, local services and e-commerce, with lists for beginners, students, developers and people starting with little money. The site also offers free tools and references, including business idea and name generators, startup cost and profit margin calculators, a self-employment tax calculator, sample business plans and founder case studies. Everything is free to read.
