AI-native companies command a 21.2x revenue multiple versus 5.5x for traditional SaaS. Pricing is shifting towards hybrid and usage-based models, with 63% expecting hybrid to become most relevant within two years. Per-seat pricing is losing ground, though 40% still use it as primary, while outcome-based models rise. The report also highlights AI's growing role in discovery: 85% of brand mentions in AI answers come from external domains, 41% see LLM-based search as the biggest change, and AI Overviews reduce top-result click-through from 27% to 11%. Companies must adapt strategies for machine readability and transparent pricing as AI influences purchasing decisions.
