We’re Cantarus, an independent agency wholly owned by our employees with a view to keeping it that way as we build for the next decade. This structure allows us to invest in our relationships with clients, our people, and our technology, which ultimately leads to better results for everyone.

As the UK technology scene has rapidly expanded, competition for the most talented people has become increasingly fierce; as such we’ve invested heavily in making Cantarus a great place to work. We provide a true meritocracy where skillsets are continually honed, challenged, and expanded every day – a place to do the best, most rewarding work of your career - and having a great time while doing so!

We are very proud of our reputation for providing the highest levels of customer satisfaction in the industry. Our Net Promoter Score of +82 is well beyond even the world-class mark of +70 and nearly triple that of the industry average of +30!

Whether you're looking for a complete rebrand, a new website, an innovative mobile app, or creative strategy consultancy, please get in touch. We'd love to help!

"Our working partnership began back in 2015-2016 when Lee & Darrin came on board to help us design, develop and launch our new website. The partnership has been growing steadily over the years which has enabled us to launch our member Community platform. We're now working on designing and developing our new member's App which is an exciting next step!"
