GameChanger launched its Gran Cave campaign on May 18, 2026, with Donna Kelce as the face of a push aimed squarely at grandparents, a group the youth sports tech industry has largely left out. The company paired the launch with a contest that asks families to nominate the grandparent who never misses a game, even from miles away.

The campaign opens a submission window from May 18 through May 31, 2026, at gc.com/grancave. One family will win a custom in-home broadcast setup valued at more than $10,000, while 365 runners-up will get free GameChanger Premium subscriptions. Winners will be announced in June 2026.

The pitch lands because it lines up with how the service says families already use it. GameChanger said more than 83% of games streamed on its platform draw viewers from outside the team’s home state, and that the average game is followed across more than three different states. The company said it covers nearly 10 million games and over 1 million teams annually, a scale that gives it a direct view into how youth sports viewing now travels far beyond the local field.

Kelce brings a recognizable face to that shift. As the mother and grandmother whose years on the sidelines have made her a public symbol of the modern sports grandparent, she framed the campaign in personal terms. She said she knows how hard it is to be at every game in person and how much it means to have a mom or grandma cheering from afar.

Sameer Ahuja, GameChanger’s president, said youth sports fandom no longer stops at the sideline or even at state lines. He said grandparents are among the most engaged people in that network of supporters, but also the ones who face the most distance friction.

That is the gap Gran Cave is trying to fill. The campaign creative leans into a “Grandmacore” look, with intentional easter eggs, custom sports-themed memorabilia and an immersive viewing wall built to make a home feel like a front row seat. It is a branded attempt to turn a practical problem — missed games, long drives, out-of-state family — into something warmer and more shareable.

The contest is open to legal U.S. residents in 48 states and Washington, D.C., age 18 and older. GameChanger is making a clear bet that the most overlooked person in youth sports may also be one of its most loyal viewers. For a company that sits inside nearly 10 million games a year, the message is not just sentimental. It is a market map.
