Best business to start in 2027? ideas with proven demand, ranked by proof
Most lists of business ideas are opinions. This one ranks ideas with proven demand, by what we could measure: how long their ad has been running, the price on their page and, when we have it, how many people search for that kind of product each month.
No idea has passed our proof check yet. We publish an idea only when its proof holds, so this list is empty for now.
How this ranking works
- Each idea gets six scores from 0 to 5. Each score is calculated from a fact we measured, not from anyone’s opinion, and the idea’s page shows that fact with its source.
- In this ranking, every criterion counts the same.
- A criterion we haven’t measured doesn’t move an idea up or down.
- Every week we check that the proof still holds. If the seller’s ad stops or the page disappears, the idea comes off this list.
