The BankerThe Banker

A live group tracker bringing your bets and friends together to watch sports.

Modern sports betting apps isolate fans by locking the tension into private, individual screens. The Banker is a full-stack web application designed to bring the sweat back to the group. By combining frictionless OCR betslip entry with a live-updating, account-free shared dashboard, it transforms a solitary habit into a collective, real-time social experience.

Sport has always been social for me

Some of my best memories are watching games with friends. The laughs, the arguments, the joy — you can’t replicate that.

Most recently one of the things we got into was going round a mate’s, cracking some beers and sticking small bets on the football. It had us watching crazy games from all over the world — good fun, and still cheaper than going down the pub.

  • Some fans struggle to commit to watching without something at stake
  • Disengaged crowds kill the atmosphere for everyone else
  • Non-bettors feel excluded when the conversation shifts to odds
  • Nothing at stake removes a big emotional engagement layer
  • Bettors juggling multiple apps creates noise and distraction
  • Modern sports can lack the constant tension spikes that esports has

Betting creates emotion, but keeps it private

The ProblemThe Problem

The moment money goes on a game it goes private

What that looks like

  • Everyone locked into their own sportsbook app
  • Tracking bets their friends can’t see
  • Constantly asking “what do you need?”
  • Group chat full of noise and screenshots
  • Non-bettors cut out of the conversation entirely

Sports are public and social. Why does betting make it private?

An OpportunityAn Opportunity

“All they talked about was their lines and their parlays. I just wanted a way to talk about the game.”

Nathaniel · 24 · Non-Bettor

“Being able to check everyone’s different bets throughout the game, that could be quite neat.”

Heath · 21 · Casual Bettor

The market is built for the bettor.
Nobody has built it for the room.

Every competitor is bettor-only, account-required, single sportsbook.

Not one of them is built for the group watching together.

How might we make betting social again?

What I LearnedWhat I Learned

Lessons Learned

  • Building something this complex end to end is within reach
  • Users are lazier than you expect
  • This product relies on the game — if the game is boring, the product dies

Next Steps

  • Get the OCR to absolute confidence
  • Add a chat to the room
  • Organise a bigger scale test to validate with built-in chat
  • Find the best audience — maybe a tipster’s private room where followers see their bets live
