Yes, and no.
It will always be free to Kick around ideas. Most users never pay. You can store an unlimited number of ideas without ever incurring any expense.
However, we do have various small annual subscription fees
for Catchers or Tournament Creators to browse certain types of commercial 'Market' ideas. These fees ensure our Catchers are serious about their role as a Catcher in these market segments.
We also have our flat 5% fee on the sale of all Commercial Ideas and Tournaments (coming soon).
