What is the auction app

Source stock without chasing the market

Spinny Partners is the app 80,000+ used-car dealers use to source their cars - thousands of inspected cars in live auctions with verified condition reports, so buying stock is fast and low-risk instead of guesswork across the market

Why a rewards programme

Keep dealers bidding, stop them drifting away

Trust was built. Now dealers needed a reason to bring more of their business to Spinny - and stay

Business is split

High-volume dealers bid on rival platforms too room to consolidate

Rewards land

Hook them with TVs, gold coins and trips for hitting milestones

Power users notice

Every small app change gets seen - like a heavy social user spotting updates

They love to compete

Dealers boast about their volumes and take pride in where they transact

Recognition is prized

Some office had a wall of awards on display

Easy to switch

A competitive market - dealers hop platforms chasing better incentives

December Dhamaal - Spin the Wheel

The problem - existing incentives had no instant hook, so low-tier dealers tuned out

How it works

Instant win on hitting the daily target

Reward right now - no wait, no ambiguity

Fun & suspense a leaderboard can't match

Higher targets unlock bigger spins

How we got there

01

Discovery

Dug into engagement data and talked to low-tier dealers

02

Framing

They needed an instant trigger, not a points dashboard

03

Design

Built the spin, reward reveal & tiered unlocks - 3 playtests

04

Launch

Shipped - deliveries, bids & wins all jumped in month one

Moodboarding

Moodboard - in-app games & rewards from other apps

The screens
