HubSpot posted Q1 revenue of $881M, up 23% reported. Subscription revenue hit $862.3M, putting ARR at roughly $3.45B. Customer count crossed 299,458, up 16% YoY. Non-GAAP operating margin expanded to 17.8%. They beat consensus by $18M and bought back $211M in stock.
The stock dropped 16% after hours.
The reported 23% growth hides the real number: constant currency growth was 18%. Five full points came from a weakening dollar. Q4 '25 CC growth was 18.2%. Q1 '26 was 18%. Q2 '26 guide is 16%. CFO Kathryn Bueker said explicitly: "Our updated guidance implies a step down in constant currency revenue growth to 16% in Q2." That is deceleration, not acceleration. Full year CC guide sits at 17%, below Q1's 18%.
The market in May 2026 is paying for reacceleration. Twilio went from 4% to 20% in a quarter. Atlassian went from 14% to 32%. HubSpot showed the opposite: flat-to-decelerating CC growth and a CFO flagging a "slow start to Q2."
AI revenue is still a story
Everyone wanted this print to prove AI is driving real B2B revenue. It is not. Not yet.
What is actually there: 8,000 customers activated Customer Agent, 10,000 activated Prospecting Agent (up 57% QoQ), and total credits consumed up 67% QoQ. Impressive growth rates off a base HubSpot does not disclose. Outcome-based pricing launched April 14, three weeks before the call.
Bueker described seats and credits as "emerging" growth levers, not core. She pointed to the AI pricing transition as hurting near-term sales execution, with April spent retraining reps on the new model. Deals are slipping while the go-to-market team learns how to sell outcome-based pricing.
AI activation counts and AI revenue contribution are very different things. The contribution will come. But not in Q1 '26.
Multi-hub remains the actual engine
62% of new Pro+ customers landed multi-hub in 2025. 40% of the Pro+ base by ARR owns 4+ hubs, up 6 points YoY. Customers with 500+ seats grew 5x in 2025. Deals over $5K MRR grew 33%, deals over $10K grew 41%. The 2024 pricing change is still flowing through (90% of legacy customers transitioned, about 50% of ARR has hit first renewal).
CEO Yamini Rangan was clear: "Our core growth levers of upmarket, multi-hub and platform consolidation, and pricing tailwinds remain solid. At the same time, our emerging AI monetization levers of core seats and credits are gaining traction."
The order matters. Core levers are doing the work. AI is secondary.
For sales teams at scale-ups watching this: platform consolidation and upmarket motion remain the most reliable compounding mechanics in B2B. AI is an accelerant on those, not a replacement. And when your CFO says "slow start to Q2" on a public earnings call, your reps are already feeling it.
Worth noting: HubSpot has meaningful ANZ presence through local go-to-market and partner ecosystem, widely used by SMBs and scale-ups across the region as a lower-friction CRM and marketing platform. The deceleration story is global, but the platform consolidation motion is the same playbook ANZ sales teams are running.
