Melt Studio built the event, sponsorship, and moderation features that took Rally — a live chat app for sports fans — to a stable, sellable product in four weeks, as part of its pro-bono prototype program.

Rally Chat: a live chat app for sports fans on game day

Rally is a competitive chat app for sports fans. During a game, fans post their best one-liners and smack talk, other fans boost or bench each comment, and the sharpest voices climb the leaderboard. For teams, venues, and sponsors, it's a way to reach fans in the moment that matters most.

The challenge: turning a fan chat into something events and sponsors can buy

The fan experience existed. To sell Rally to events and sponsors, it needed what a buyer asks about: sponsor presence in the chat, attendance numbers, moderation they can control, and an experience that holds up when thousands of fans watch the same game on different broadcast delays — all without scaling costs out of control.

The solution: event, sponsorship, and moderation features built for game day

• Event sponsorship built into the chat, and attendance tracking to show sponsors the reach.

• Replies and replay, so fans can respond to each other and relive the best moments.

• An anti-spoiler delay button that holds messages back when a fan's stream runs behind the live action.

• Instant content on open: new fans see the conversation already in progress, plus a quick first-time tutorial.

• Event branding, with a color scheme customized for each event.

• Event-specific moderation: admins set banned keywords per event and act on any message that contains them.

• Performance and cost tuning so the app handles scale without the bill growing with it.

• 
  

How a dedicated team built it in three weekly sprints

A dedicated team in one-week sprints: sponsorship, attendance, and replies first; then the delay button, message history, tutorial, and branding; then moderation and a performance pass.

Results: a stable fan chat, ready to sell to events and sponsors

• Sponsorship, attendance, and moderation — the features buyers ask for — live in the product.

• A game-day experience that holds up across broadcast delays.

• A platform confirmed stable and ready to start selling at closing.

• A defined next milestone: moving the real-time layer to infrastructure that stays affordable at scale.
