Over a year on from the last ranking, at which point the UK entity's Companies House filings were overdue, NTT's UK revenues have increased significantly to £242.5m. Meanwhile, gross profit grew 82.6 per cent to £63m, even as the business bought out London-HQ channel partner Sapphire in November.

Backed by Horizon Capital since December 2019, Sapphire has a headcount of around 420 people and delivers software and services to primarily mid-market customers in the US and UK through its partnerships with SAP, ServiceNow and more.

The acquisition was crystal clear for NTT DATA Business Solutions, a group company of NTT DATA and a global strategic partner of SAP.

Speaking to CRN about his agenda for 2024, Gabriel says the takeover tops the list.

"My top priority is the integration into NTT DATA and how we can help them in the UK accelerate their mid-market as well as helping them engage their install base of existing customers with some of our enterprise propositions.

"We're going to be their mid-market engine in ERP. But obviously our ServiceNow proposition fits beautifully into their customer base.

"Our data analytic proposition fits beautifully in there. Our asset management proposition fits beautifully in there. So it will be becoming their engine room in the mid-market, as well as enabling them to access some of our great capabilities that we've built over the last three years."
