Car buying where the dealers do the competing
Car buying is hours of listings, calls and haggling. RevXtra flips it: describe the car once, and approved franchise dealers compete for your business with blind offers in a 24-hour window. We designed and built the complete product, buyer journey, dealer bidding desk and admin operation, over a hundred screens deep.

Sides of the platform
01 / the problem
Buyers do all the work. RevXtra makes dealers do it.
The model lives or dies on its mechanics. Offers are blind, so dealers bid their best price rather than a pound under the competition, and the 24-hour window creates urgency on the dealer side instead of the buyer's. Every screen had to reinforce that this is offers from dealers competing, never an auction the buyer runs.
It also had to work three ways at once: a consumer experience that feels as easy as ordering a taxi, a dealer desk that makes structured bidding fast, and an admin operation for approving dealerships and tracking the £250-per-unit fee model.
- 01 Design blind bidding buyers and dealers both trust
- 02 Make a 24-hour offer window feel effortless
- 03 Give dealers a pipeline worth working
- 04 Run approvals and fees from a real back office
02 / the solution
One platform, three sides, a hundred-plus screens.
Buyers get a guided search wizard, matched results, rich vehicle pages with history checks, a live offer board with countdowns, side-by-side comparison, reservation and in-app chat, plus Your Garage to run several searches at once. Dealers get onboarding, live leads, a structured blind-bid form, pipeline, stock and multi-branch management. Admin covers dealership approval, listings, fees and reporting.
The whole experience runs as a fully clickable product with realistic data, every flow walkable end to end, backed by a full copy pass that stripped auction language out of the platform. The backend substrate it wires into is the same marketplace core that powers our production platforms.

RevXtra exists as a complete, walkable product: 106 screens across buyer, dealer and admin, holding page live while the client takes it to dealer groups and investors.
“We’ve been working with James and the team at Code23 on the development of RevXtra and the experience so far has been excellent.
From the outset, they’ve taken the time to really understand what we’re trying to build rather than simply doing what we ask. They’ve challenged ideas when needed, offered solutions and helped turn what started as a concept into a genuine product.
Communication has been great throughout and it genuinely feels like they’re invested in making RevXtra a success, rather than us just being another client.
I’d have no hesitation recommending James and the Code23 team.”
