Vertical SaaS Top 20 Public Companies Now Valued at $300B+ — AI-Native Platforms Pulling Away from AI-Enabled Ones
Stax·medium signal
The top 20 public vertical SaaS companies in the U.S. are now collectively valued at over $300B, with Toast (restaurant POS) and Procore (construction) leading. Procore now uses AI to scan drawings, change orders, and safety reports, flagging inconsistencies across thousands of documents. The market is splitting into three tiers: traditional SaaS (declining), AI-enabled SaaS (maintaining), and native AI SaaS that executes entire workflows autonomously (growing fastest). Investors no longer fund generic vertical software without proprietary data moats.
