HubSpot is turning to one of its founders to lead its next phase of growth. The software company has brought back Brian Halligan as chief executive, replacing Yamini Rangan, as it looks to reshape its business around artificial intelligence and changing customer needs.

Halligan, who co-founded HubSpot in 2006, took over the CEO position. Rangan stepped down from the role and also left the company's board. The leadership change comes as HubSpot attempts to rethink how it develops and sells software in an increasingly competitive AI market. 

Co-Founder Returns to Lead HubSpot

Halligan previously served as HubSpot's CEO before handing the position to Rangan in 2021. His return signals a significant shift in leadership as the company prepares for what it describes as a new chapter.

The move follows organisational changes announced in October, when HubSpot cut approximately 7% of its workforce, affecting nearly 660 employees. The company said it wanted a flatter structure, fewer management layers and teams with clearer responsibilities.

HubSpot has been placing greater emphasis on AI-powered tools that can help businesses manage sales, marketing and customer relationships. 

CFO Kate Bueker to Retire in February

The executive changes also extend to HubSpot's finance department. CFO Kate Bueker plans to retire on February 11, 2027, with Karen Burgess appointed as her successor. Burgess is expected to take over on the same date, allowing time for the transition.

The appointment adds another important change to the company's senior leadership as it works through its restructuring plans. 

AI Strategy Drives Company's Reset

HubSpot's leadership overhaul comes at a time when AI is changing the software industry. The company reported third-quarter 2026 revenue of $947.6 million, up 17% year over year, but is facing pressure to adapt its products and operating model.

Its challenge will be to turn its AI ambitions into products that customers are willing to pay for while maintaining growth and profitability. Halligan's return puts the company's co-founder back in charge at a particularly important point in that transition.
