Problem

Who sports apps are built for

~70%

of 183M sports fans have never bet

~30%

bettors — every major app serves them

Fan sentiment

48%

support banning sports betting ads

Washington Post

45%

say betting isn't good for society

Up 29 pts in three years — Washington Post

The 30% is big business

Sports apps chase bettors, not fans who care about the game. Buzzr is for the fan who wants to feel something.

How might we help sports fanscapture and share how a game felt,not just how it ended?

Competitors

The sports app market hits $13B by 2034. It is fragmented.

Buzzr pulls the useful social pieces into one sports home.
