Payments should never be
the reason a user leaves your site.

Why we built Fluid.

The cashier is the most expensive piece of UX an iGaming operator owns — and historically the least loved. Users who clear registration, KYC, and game selection drop off at deposit, exactly when the operator has paid the most to acquire them. After 20 years on the operator side, we decided to fix it.

The cashier should be a retention engine, not a money-in, money-out tool — where great UX drives retention, upsell, and CRM.

How we got here.
