Brian Halligan

In a 2026 interview, he recalled growing up in Massachusetts, delivering newspapers, working in restaurants and running a painting business from high school through college. His original ambition was to become a technology-company executive.⁠[3]

He graduated from the University of Vermont in 1990 after studying electrical engineering with a biomedical option. Returning to campus, he credited his engineering education with helping him communicate with technical colleagues.⁠[4]

After graduation, he spent roughly a decade at PTC, rising into sales leadership and developing its Asia-Pacific business.⁠[1]

He recalled accepting a last-minute assignment to Japan in 1993 and beginning work in an unfamiliar market.⁠[3]

He was vice president of sales at Groove Networks from 2000 to 2004 and served as a venture partner at Longworth Ventures before founding HubSpot.⁠[5]

He earned an MBA from MIT Sloan, whose records identify him as a member of the class of 2005.⁠[6]

A June 2006 seed-funding announcement said Halligan and Dharmesh Shah had founded HubSpot in 2005 while studying at MIT and had raised $500,000 from private investors.⁠[7]

In his later Sequoia biography, he dates HubSpot’s beginnings to 2006, differing from the early funding announcement.⁠[2]

Recounting the company’s beginnings, he contrasted declining results from outbound sales with the audience attracted by Shah’s blog. The team built around inbound marketing and committed to serving small and midsized businesses.⁠[8]

He co-authored Inbound Marketing with Shah.⁠[9]

He and David Meerman Scott co-authored Marketing Lessons from the Grateful Dead, first published in 2010, with a foreword by Bill Walton.⁠[10]

HubSpot began trading on the New York Stock Exchange as HUBS on October 9, 2014; an October 15 announcement confirmed the IPO’s completion. That September, it had announced a sales platform including a free CRM and Sidekick.⁠[11]

Following an investigation into executives’ attempts to obtain a book manuscript, HubSpot’s board sanctioned Halligan for delayed reporting. It also found that he had not participated in the underlying conduct or impeded the review.⁠[12]

Halligan acquired Jerry Garcia’s Wolf guitar at a charity auction in late May 2017 benefiting the Southern Poverty Law Center. A longtime Grateful Dead fan, he also studied its approach to building a community.⁠[13]

HubSpot announced that Yamini Rangan would become CEO on September 7, 2021. Halligan moved to executive chairman, focusing on products, partnerships and long-term strategy; Rangan had already managed daily operations during his absence.⁠[14]

He later wrote that a 2021 snowmobile accident prompted him to reconsider his desire to remain CEO and the leadership skills needed for the company’s next stage.⁠[15]

In 2022, Propeller announced a $100 million fund for ocean and climate technologies and a partnership with Woods Hole Oceanographic Institution. Halligan and the team supported commercialization of research and introduced a three-day Ocean MBA.⁠[16]

MIT awarded Halligan its 2023 Monosson Prize for Entrepreneurship Mentoring.⁠[17]

In a 2024 essay, he treated company culture as another product to develop and emphasized increasing attention to customers as the business grew.⁠[15]

A May 8, 2025 proxy supplement states that Halligan stepped down as executive chairman and became a non-executive director effective that day. Lorrie Norrington became chair; Halligan remained on the board.⁠[18]

In November 2025, Scott announced their revised edition of the Grateful Dead marketing book, updating its discussion of the band and business.⁠[10]

Sequoia’s Long Strange Trip is hosted by partner Halligan and features CEOs discussing company growth and transformation.⁠[19]

Propeller’s current team page lists him as a general partner.⁠[20]

MIT continues to list him as a senior lecturer teaching Scaling Entrepreneurial Ventures.⁠[6]

His public personal website redirects to his Delphi page, which offers a digital twin and links to public accounts.⁠[21]
