Who’s taking over from Tez as Giacom swaps CEOs?
Share on LinkedinShare on Twitter

Giacom this morning announced former TalkTalk boss Susie Buckridge will replace longstanding incumbent Tez O’Brien as its CEO.

Buckridge will lead all aspects of the Inflexion Capital-backed business across its 750 colleagues and 6,000-strong channel partner community.

The cloud, mobile comms and connectivity distributor claimed her arrival coincides with efforts to evolve from a channel marketplace into “the platform that powers how MSPs and resellers buy, sell, manage and support technology”.

She was most recently CEO of TalkTalk Consumer, where, Giacom claimed, she “led the business through a significant period of transformation, simplifying the technology estate, introducing a new CRM platform to improve the customer experience, launching products that set TalkTalk apart and strengthening the company’s data and AI capability”.

O’Brien became CEO of Microsoft, BT, Sky, Vodafone, VMO2, Cityfibre, Acronis, Barracuda, Bitdefender and Huntress partner Giacom in July 2023 when it was unified with the Digital Wholesale Solutions business he had previously led since 2019.

In his new role of Corporate Development Advisor, O’Brien will continue to help drive Giacom’s CSR initiatives, including The Big Goal and The Big Green Goal, Giacom Chairman Matthew Riley confirmed in a canned statement.

“The business has created a strong reputation as a trusted partner for MSPs and resellers across the UK. With a 100% channel-only focus, Susie’s appointment marks the beginning of our next chapter of growth,” Riley said.

“Her experience leading large-scale technology and operational transformations makes her the right leader to accelerate our platform and AI ambitions.”

“Giacom has built something special – a business that partners genuinely trust, with the scale and ambition to reshape how the UK channel works. The opportunity ahead is significant,” Buckridge added.
