The Numbers
SaaStr AI Annual 2026 had 78 Gold-to-Diamond sponsors. Only 15 (19%) also sponsored in 2025. That means 63 sponsors (81%) were net new, and 48 of last year's sponsors did not come back.
Four out of five sponsors were companies that did not sponsor 12 months earlier. Nearly half of the previous year's sponsors were gone.
Founder Jason Lemkin calls it rebuilding, not refreshing. The customer base for B2B budget shifted under their feet in one show cycle.
Who Left, Who Stayed
Of the 48 sponsors who did not return, 40 (83%) were classic pre-AI B2B or legacy services firms. Only 8 (17%) were AI-native.
The churn was not random. It was a category collapse. Companies that spent $250k+ on booths 18 months ago: gone. Not because the event got worse, but because their growth slowed, CMOs got fired, and marketing budgets got cut. Some are quietly winding down entirely.
The sponsors who stayed: Google Cloud, Okta, Rippling, G2. Companies with an authentic AI story or horizontal platform play. The pure-play "we sell software to mid-market sales teams" sponsor of 2022 simply disappeared.
The Replacement Floor
The 63 new sponsors are overwhelmingly AI-first: Replit, Lovable, Harvey, Cohere, Vercel, Relevance AI. Companies that mostly did not exist at sponsor scale in 2024. Some literally did not exist as companies. In 2026 they are writing $50k, $100k, $250k checks because their customers are at the event.
SaaStr started prospecting AI-first sponsors 12 months ago. Most were not ready then. Most are now.
What This Means for Sales Teams
Your customer base is doing the same thing. If 75% of SaaStr's paying customers turned over in 12 months and the event still grew, the replacement rate of who is willing and able to spend money in B2B has gotten brutal.
The accounts you signed in 2022 are not the accounts that will grow you in 2026. A meaningful chunk are getting acquired, stalling, or quietly cutting your line item.
The companies writing checks in 2026 and 2027 are mostly: AI-native companies spending aggressively to land mindshare, old-guard companies that successfully repositioned around AI, and infrastructure plays riding the AI capex wave.
If your 2026 pipeline still looks like your 2023 pipeline, you have a problem you may not see yet. The lead time is real. If you wait until they are already buying, you are at the back of the line behind every other vendor chasing the same logos.
