Brian Halligan Returns as CEO

Halligan co-founded HubSpot in 2005 with chief technology officer Dharmesh Shah and served as chief executive for 16 years, leading the company from its founding through its initial public offering to a market value of more than $30 billion in 2021. He never left the board.

Announcing his return on social media, Halligan wrote that he and Shah were completely refounding the company, calling it day one and describing HubSpot as now the Customer Harness Company. He said he would post in the coming days about why he was coming back and what his plans are.

The change comes as HubSpot races to reposition itself around artificial intelligence. In its third-quarter report eight days earlier, Rangan had said AI was moving software from tools that help people do work to agents that do the work and deliver outcomes.

Rangan’s Record

Rangan joined HubSpot in 2020 as its first chief customer officer and became chief executive the following year. Under her leadership, the company said it grew from 135,000 customers to more than 311,000, and from $1.3 billion in revenue in 2021 to an expected $3.7 billion in 2026.

HubSpot’s third-quarter results, reported on 4 November, included revenue of $947.6 million, up 17%, and 311,704 customers, up 12%.

A New Finance Chief Too

HubSpot also announced the long-planned retirement of chief financial officer Kate Bueker, effective 11 February 2027, after eight years in the role. Karen Burgess, currently senior vice president and chief financial officer of Adobe’s Creativity and Productivity business unit, will join HubSpot on 30 November as executive vice president of finance and take over as chief financial officer when Bueker leaves.

The company reaffirmed the fourth-quarter and full-year 2026 guidance it issued with its third-quarter results on 4 November.

Conclusion

Halligan’s return puts a founder back in charge of HubSpot at a moment of rapid change in the software industry. With a new chief financial officer arriving and guidance reaffirmed, the company is betting that a refounding led by its co-founder can carry it through the shift to AI agents.
