HubSpot Says AI Is Changing How Customers Buy. It Guided Growth Down to 12%.

HubSpot told investors its fourth-quarter revenue will grow 12%, down from 17% in the third quarter, as buyers weighing AI slow its sales and a $60 million to $70 million severance charge arrives.

Growth is slowing while use of HubSpot’s AI products rises. For a buyer, that gap is the question: AI usage a vendor reports does not by itself show up as upgrades and renewals in the vendor’s results.

What is slowing the sale?

CEO Yamini Rangan said customers now want proof before they buy and want AI to work with their own data. HubSpot added free trials and pricing tied to outcomes in the second quarter, knowing both would stretch buying cycles. Agent trials grew 64% from the second quarter to the third, but customers need hands-on help to turn a trial into a paid plan.

Larger customers bring more people into each decision: bigger buying committees, with CEOs, chief technology officers and boards involved. Smaller customers are cutting costs. Win rates run nearly three times higher in deals with five or more committee members when HubSpot’s team engages multiple stakeholders, Rangan said. CFO Kate Bueker said the guidance assumes these pressures last into 2027.

HubSpot is also changing what it charges. A pilot of seats plus credits began in the Nordics in April and Benelux in June, and HubSpot has extended it to new customers across Europe, the Middle East and Africa in the fourth quarter. In the Nordics and Benelux pilots, which HubSpot calls early results, credit use runs two to three times higher than in regions outside the pilot, at a lower average selling price.

Are agents making up for it?

Usage keeps climbing. Customer Agent resolved more than 2 million support issues in the third quarter, monthly credit consumption has risen nearly 2.5 times since the start of the year, and monthly agent actions among Pro+ customers are up fivefold.

Net revenue retention fell about a point from the second quarter to 101%, Bueker said, as budget optimization held back upgrades. HubSpot expects full-year 2026 retention to finish about two points below 2025, and net new annual recurring revenue to fall from 2025.

What does the reorganization cost?

The reorganization announced Oct. 6 cut about 7% of HubSpot’s workforce, its quarterly filing shows. Bueker said fourth-quarter operating income under generally accepted accounting principles (GAAP) will carry the $60 million to $70 million severance charge. The filing’s larger range, $65 million to $75 million, is the estimate for the whole plan, mostly severance, notice periods, transition support and benefits.

The cut lifts fourth-quarter operating profit, Bueker said, but HubSpot is reinvesting a significant part of the savings in employee retention, AI talent and its platform. Fourth-quarter guidance puts the non-GAAP operating margin at 23%, and its 2027 target stays at 23% to 24%.
