We were faced with extremely tight deadlines that other development teams didn't believe would be possible to meet. JUXT hit the ground running adding value from day 1. They helped us develop a complex game engine and Datomic-based data stores for two production systems, both went live smoothly and successfully.

Our Success stories

In 2013 MailOnline, the worlds busiest newspaper website, was rewritten in Clojure. JUXT helped to build a replacement front-end system written in Clojure yielding the benefits of being much simpler and easier to maintain, delivering a range of new functionality to the business.

Our Success stories is a major online property portal advertising hundreds of thousands of new properties to the general public. It was launched with a high profile TV campaign in January 2015 and is now going from strength to strength.

Juxtaposing ourselves with the client, we drew upon our collective experience of past Clojure projects to provide sound architectural guidance and a productive development environment. We provided technical leadership and helped foster an organic developer-led, self-organising culture. and JUXT

JUXT was founded in London, arguably the world's foremost financial centre, in the crucible of highly-complex projects within investment banks, notably Deutsche Bank and UBS. Our staff have many years of software development experience in investment banking and are comfortable working within the technical domain and language of complex financial instruments.


I asked JUXT to use their Clojure wizardry to make sense of some very big and very awkwardly-structured data, which we needed urgently. They were a lifesaver: they produced exactly what was needed, in a tight timescale, while maintaining very high levels of data security. I'll certainly go to JUXT again.

Our success stories

JUXT have collaborated with Mastodon C a few times to help produce solutions for clients.

Energy Saving Trust approached Mastodon C with a small problem but one that required custom development. They were collecting reviews from a number of sustainability experts, who each put their responses into an Excel spreadsheet template.

The problem was to take these spreadsheets, and quickly derive a series of custom reports which could be accessed online by authorised parties. Building a system using Clojure is often a good compromise for a build-versus-buy dilemma.

Future tech

Working with JUXT was a delight. They demonstrated flexibility and used their technical know-how to deliver a solution that meets our immediate needs and will scale as our business grows.

Adrian Ulisse, Better Cities CEO & Founder

Our success stories

Ride On is a public bike scheme with a difference. The advantage with Ride On bikes is that they are electric, meaning that the bike itself will help you pedal. This has positive implications for the environment because fewer trucks are needed to move the bikes from station to station, as people will cycle uphill as well as downhill.

The evidence suggests that people use electric bikes more than standard non-powered bikes, and so this helps to reduce city traffic, whilst giving the rider a happier experience.

It's a win-win and a hugely exciting project. At JUXT we're thrilled to be a part of it.
