They are bringing their bidders 13,000 auctions a year within an infrastructure that allows secure transactions, easy bidding and comprehensive searching to ensure no opportunity is ever missed.

Although it’s the most popular and active auction platform in the UK, ATG’s GapLive Online Auction Broadcasting and Live Bidding Application was still using outdated technology. 

It was great for video streaming, but mobile device support was lacking and had performance issues.

While the in-house engineering team was working on the streaming side of the codebase, I ran several workshops with internal stakeholders and marketing as a part of the product discovery process. To support the workshops, I have created different hi-fi prototypes as proof of concept and bring them to life by using Invision.

During the workshops, we have discovered that presenting the auction in a 2 column structure which holds prioritised/grouped information would be the ideal solution for ease of the following activity on lot and auction catalogue in general while enjoying live auction streaming of the biggest auction houses around the world.
