Display data publicly to an unlimited number of end users for a simple flat monthly price.

The most common challenges our customers face are the licensing restrictions and controls associated with displaying real-time data to end users. With other real-time data products, data must be secured behind an entitlement (login) system, end-users need to be classified as pro/non-pro with cumbersome onboarding processes, and user counts must be reported directly to the exchanges every month.

Poly.feed+ eliminates this complexity, allowing you to display data publicly to an unlimited number of end users for viewing via television, websites, and mobile devices — no entitlement system, end-user classification, or reporting necessary.
