HubSpot Co-Founder Brian Halligan Returns as CEO as Yamini Rangan Steps Down

2 min read

HubSpot announced on Thursday that Yamini Rangan has stepped down as Chief Executive Officer and from the Board, effective November 12, and that co-founder Brian Halligan has returned as Chief Executive Officer, effective the same day, to lead what the company called a refounding. Rangan will remain with the company through December 1 to ensure a smooth transition, the company said. HubSpot, based in Cambridge, Massachusetts, sells a customer platform, including marketing, sales and service software, to growing businesses, mainly small and medium-sized companies, Reuters reported.

Halligan co-founded HubSpot in 2005 with chief technology officer Dharmesh Shah and served as its chief executive for 16 years, leading the company from its founding through its initial public offering to a market capitalization of more than $30 billion in 2021, and he has served on its board since 2005, the company said. As chief executive, he will reimagine HubSpot from the ground up across product, go-to-market and culture. “Chapter one was creating the inbound marketing category,” Halligan said. “Chapter three is building the customer relationship harness that will enable millions to grow better. This is a refounding, and I can’t wait to start.”

Rangan led HubSpot from September 2021, a period in which the company 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, scaling into a global, multi-product platform, expanding upmarket and building artificial intelligence into its offering, the company said. Board Chairperson Lorrie Norrington said the board is united in its support of Halligan’s refounding, combining, she said, unmatched knowledge of HubSpot’s customers and culture with a clear vision for where artificial intelligence takes the category.

The leadership change extends to the finance office. Kate Bueker, the chief financial officer for eight years, will retire on February 11, 2027, in what the company described as a long-planned move, and will then serve in an advisory role through December 31, 2027. Karen Burgess, currently senior vice president and chief financial officer of Adobe’s Creativity and Productivity business unit, will join HubSpot on November 30 as executive vice president, finance, and will succeed Bueker as chief financial officer on February 11, 2027, the company said.
