A circular directory of thousands of tiles. The closer to the center, the bigger the spotlight.
CircleSaaS is a circular directory of startups: thousands of tiles arranged in concentric rings, one tile per product. Closer to the center means a bigger tile and more attention; every ring out from there, all the way to the free outer rim, is still a real spot on the board.
A list ranks; a circle just shows everyone at once, at whatever size they picked. There is a free tier so anyone can join, and paid tiers for a bigger tile closer to the middle. Same board, one straightforward pricing idea.
