It’s been a frenetic few days for top leadership changes in the channel, with Kaseya, Infinigate, Exclusive Networks and Iomart all almost simultaneously announcing big departures, arrivals or promotions.
Dimes departs

Iomart got the ball rolling on Friday by announcing CEO Lucy Dimes has stepped down.
Dimes took the reins of the AIM-listed private and public cloud provider in September 2023 following the abrupt departure of predecessor Reece Donovan – and oversaw its £57m acquisition of Microsoft partner Atech in October.
Despite Iomart’s efforts to pivot Iomart more towards public cloud, its shares have more than halved in 2025 (and have fallen by over 90% since 2021).
Dimes’ departure comes a month after Iomart announced in a pre-close trading update that revenue for its year to 31 March 2025 is set to rise 13% to £143m. Its core business is on course to shrink by 7%, however.
Chair Richard Last will become Executive Chair while a successor is sought, Iomart said.
“The Board would like to thank Lucy for all her work in helping to reposition iomart’s business to more fully address the opportunities in the Public and Private Cloud and Security markets,” it stated.
Schlichtherle splits

Just one working day later, Bridgepoint-backed cybersecurity VAD Infinigate also announced its CEO is stepping down – although in its case it has a successor lined up.
Klaus Schlichtherle said he felt it is a “good time to hand over the reins” of the Switzerland-based outfit after eight years.
He will be succeeded by Marco van Kalleveen on 16 June.
Former McKinsey & Company and DKV Mobility leader van Kalleveen boasts “considerable experience in architecting successful strategies to manage and scale B2B businesses, supported by private equity sponsors”, according to Infinigate President Graeme Watt – who led the CEO hunt.
Schlichtherle’s exit comes after Infinigate last week confirmed it is on course to break the €5bn revenue barrier by 2027-28 after outgrowing its 11 major EMEA peers.
“We have achieved a lot together, most notably through the additions of Nuvias, Starlink, Vuzion and Wavelink to the Group, which have been critical in helping Infinigate establish itself as a global leader. I am excited to see what the next phase of growth under Marco’s leadership holds for the company,” Schlichtherle stated.
Tomlin takes on Northern Europe

Infinigate’s biggest like-for-like peer, Exclusive Networks, also announced a change at the top today as UK&I leader Rob Tomlin was handed a beefed-up role.
As the €6bn-sales cybersecurity VAD’s Regional Vice President, Northern Europe, Tomlin will now also look after the Nordics, Benelux and Baltics regions.
Having joined Exclusive from Dell last March, Tomlin’s tenure has seen him spearhead a major UK push into the data management space, led by the signings of NetApp and Druva.
His promotion comes after Paris-listed Exclusive sold a 66.7% stake to CD&R and Permira in December.
“In my time as Managing Director, UK & Ireland, I’ve absorbed everything that is unique and special about this company and I’m excited to now take that experience into the Northern Europe region and continue our growth in the way only Exclusive Networks can,” Tomlin said in a canned statement.
Succar says ‘yes’ to Kaseya

Kaseya completed the CEO-swapping action by today unveiling a new talisman in the shape of Rania Succar.
The MSP software vendor’s hotseat had been sitting vacant since predecessor Fred Voccola abruptly departed the role in January.
Succar has over the past nine years been “helping small and midmarket companies thrive” at Intuit, most recently as Head of Intuit Mailchimp.
Her appointment comes after Insight Partners-backed Kaseya wrested the RMM and PSA marketshare lead from ConnectWise for the first time since records began, according to Canalys. It now claims to serve nearly 50,000 MSPs globally.
“In our search for a new CEO, we sought a leader with the vision and capability to elevate Kaseya into one of the most essential platforms for MSPs and the broader SMB technology ecosystem,” stated Mike Triplett, Chairman of the Board at Kaseya and Managing Director at Insight Partners.
“Rania’s bold leadership and track record in building and scaling innovative, customer-centric businesses for the SMB market make her an ideal leader to guide Kaseya into its next chapter and potential IPO.”
