Eoghan McCabe, one of the founders of Irish tech unicorn Intercom, is to return to the chief executive's role, two years after he moved out of it to become chairman.
Karen Peacock, who replaced Mr McCabe in 2020, is stepping down from the CEO role and moving to an advisory role.
In a letter to staff posted on the company's website, Mr McCabe said he was returning now because he had been asked to do so by the board.
"In the two years since, I got the break I needed, started some new passion projects, and found more time for investing in and helping some great new founders, a number of which are former Intercom employees," he wrote.
"But I could never stay too far from this company. I still deeply cared about its success and its place in the world. Recently, some of our board members asked if I’d come back and I felt called to finish what I started. And so here I am!"
Mr McCabe continued that he has a very specific vision for the company and how to achieve it.
"It involves going back to our roots, some extreme focus, and a bet that we’ve never been willing to make before: picking a lane and being clear about what we’re not going to do," he said.
He added that the company is aiming to become the dominant platform for customer support, by going head to head with Zendesk.
Valued at over $1bn at its last fundraising, Intercom is one of Ireland’s tech unicorns.
Last month it was reported that it had laid off just under 5% of its workforce around the world, amidst the difficult economic outlook.
23 of the 49 staff work who lost their jobs work in the Dublin office.
In total the firm, which makes customer communication and support software, employs around 1,000 staff, with 400 of those in Ireland.
