58%
share of top 10 vendors in 2026 (vs 71% in 2022)
Stack concentration is reversing.
The top 10 CRM vendors held 71% of review volume in 2022 — they hold 58% in 2026. The long tail is real, fragmented, and growing 1.4× faster than the named leaders. CI strategies anchored on Salesforce + HubSpot + Microsoft miss the vendors actually winning Series A and Series B deals.
