Growth in B2B SaaS and AI companies appears healthy but also uneven, according to Maxio’s new B2B Growth Report based on more than $40 billion in billings data from over 2,000 companies between 2024 and 2025. While year-over-year growth averages came in at an18% clip, more than 35% saw their growth contract. This underscores that execution is now more important than market growth. “Growth didn’t disappear in 2025; it became harder to earn,” said Alan Taylor, COO at Maxio. “The winners weren’t chasing every trend. Whether AI-native or traditional SaaS, the top performers stayed focused on solving real customer problems.”

The report found growth inflection points emerging earlier than expected, particularly around $5 million and $25 million in billings, while vertically focused companies outperformed horizontal peers. AI-driven growth proved effective only when AI sat at the core of the product, not as an add-on. “Average growth numbers only tell part of the story,” said Ray Rike, founder and CEO at Benchmarkit. “What stood out is how early growth friction shows up.” Looking ahead, 72% of companies expect faster growth in 2026, tempered by greater discipline and operational focus.
