Hi! Quick story about pizza and founders.

Our Premium pass costs $19. That's one large pizza.

You know what happens after you eat a large pizza? Nothing. It's gone. Maybe some regret.

But $19 on Premium? Your product gets a permanent dofollow backlink from a DR 75 directory. Featured on the homepage. A guaranteed tournament slot.

That listing stays there for years. The pizza? Gone in 20 minutes.

The price is identical. The value is not.

Launch your product, not your calories.
