Despite a slight drop in revenue, London-based Sabio moved up two spots in the list this year.

The Amazon, Avaya and Google Cloud partner cited vendor turbulence in the wake of Covid-19 as a driving factor behind its figures, alongside continued market instability and the war in Ukraine driving up consumer costs.

Sabio entered the CRM space by acquiring Salesforce consultancy makepositive in March 2021, after the 2020 acquisition of Team Vision, a comms technology specialist.

According to the company, much of its most recent financial year was spent fully integrating the businesses as part of its ‘Sabio One' strategy.
