Earn money with no investment
Starting with no upfront money is possible: many SmartExtraLab ideas mainly need time, a phone or a bike you already own. This page lists sheets marked as no investment, meaning a zero starting budget, with that filter already applied. You will find local services, one-off gigs, seasonal work or online activities that need no gear purchase on day one.
Figures on the sheets are indicative only and depend on demand where you live. If later you are ready to invest a little to launch an activity with AI agents, AI Agent Business Lab presents business ideas, including free starting points — the same referral the rest of this site uses for people willing to spend. Until then, stay on zero budget, read the rules guide for any declarations, and try one idea at a time.

Frequently asked questions
Does « no investment » mean everything is free?
It means a zero starting budget on our sheets: nothing you must buy to begin. Small costs may appear later (travel, phone). Read each sheet's budget note.
Why mention AI Agent Business Lab?
Only for people who later accept investing a little. On SmartExtraLab, the AIABL referral follows the same rule as elsewhere (ideas with a budget). It is not required for the zero-euro ideas on this page.
What about taxes?
It depends on country, amounts and status. The rules guide gives the general framework in France and Belgium, not personal advice.
