TL;DR: Business ideas for women are easy to list and hard to start, so this guide only uses ideas that real women in Europe already turned into companies with their own money. You get 13 ideas from founders in 9 countries, each with the founder's first steps, our estimate of the first-month cost in euros, the time to a first sale and one thing to do this week. The cheapest start was £20 of flyers and a hoover (Mrs Bucket, Wales), the most expensive about €70,000 of savings (Mokosh, Poland). Price your own version in the free planner below before you spend anything.
Practise your business before you spend a cent. In the Fe/male Switch startup game you build a startup step by step with an AI co-founder: you test your idea, set a price and plan your first customers, and the mistakes cost game points instead of savings.
