How do I prove I have enough money for a Finnish startup entrepreneur permit?

The permit requires that you can support yourself for the entire period it covers, so secured means of subsistence is a key condition.

Acceptable evidence includes bank statements, documentation of startup funding or investment, company accounts, rental income contracts, or an employment agreement that provides additional income.

Gather clear, up-to-date financial documents that cover the full requested permit duration. The same income condition is reviewed again when you apply to extend the permit.
