Remarkable Group appoints Ian MacArthur as new CEO of Sagittarius

Remarkable Group (The Remarkable Group International) has appointed Ian MacArthur as the new CEO of Sagittarius, a top 50 UK digital agency, a specialist in digital customer experience and Sitecore platinum partner.   

MacArthur joined Sagittarius in 2018 as its director of global digital strategy, later becoming the agency’s Chief Experience Officer overseeing experience optimisation, and eventually taking on additional responsibility for sales, marketing and client services functions.

In his new role as CEO, which takes effect on 6th September, he will oversee the company’s growth both in the UK but also into new markets across the US and Middle East, in line with Remarkable Group global expansion plans. 

Leading the charge on new client wins including Liontrust, Cooke Optics, ICIS and Saga – MacArthur speaks with passion about his appointment, saying: “It’s an honour to be given the guardianship of Sagittarius from the original founders and previous CEOs, Paul Stephen and Nick Towers – the gravity of that is not wasted on me. As a progressive digital business, Sagittarius has a long history in helping great brands shape their destiny online through creating experiences that convert and, as a creative leader that obsesses over my customer’s customer, I’m thrilled to take that same winning mindset and apply it to our own growth story.”

Bringing nearly 30 years of experience, MacArthur has held senior roles across client brands, consultancies and now the agency space. From large NGOs such as NSPCC/ChildLine, where as CMO he led the famous FULL STOP Campaign through to advising commercial brands like Apple and Nike.

MacArthur has been recognised in The Guardian’s Future 50 to watch, The Drum’s Digerati and BIMA HOT 100 for his work. He has also won a raft of awards and multiple Grand Prix for his groundbreaking use of digital in advertising, design, marketing and customer experience. 

Outside of work, he continues his passion for supporting causes as co-chair of the British Interactive Media Association’s charity council.

Sagittarius, as a leading UK digital agency, was formed in 2010, and currently counts five offices globally. In 2020 Sagittarius co-founders, Nick Towers and Paul Stephen leveraged the expertise and value created by Sagittarius to build the Remarkable Group, a new group focused on connected digital experiences and digital transformation of which Sagittarius continues to sit at the heart.

Commenting on the appointment, Nick Towers, Sagittarius Co-Founder, former Sagittarius CEO  and now Remarkable Group CEO, said: “We are really excited for Ian and his team to be taking the reins at Sagittarius. Ian has been a part of the senior leadership team for some time now and has used that time to build a deep understanding of our clients, their needs and how to deliver great work and experiences that convert for them. Ian has a fantastic mind – curious, innovative and creative and we know he will do great things at the helm of Sagittarius.”

More recently, the Group acquired Tanasuk, expanding its footprint into the Middle East with Tanasuk’s best-in-class Sitecore and Microsoft engineering capabilities and is to announce its next acquisition in the customer experience space in the coming weeks.
