Our read

AEO and GEO exist because discovery is moving from blue links into AI answers. Academics coined 'generative engine optimization' in a 2023 paper, vendors adopted AEO and GEO as product names in 2024, and G2 created a dedicated category in March 2025. It's early and crowded at the same time. We count about 33 dedicated tracking tools, roughly 13 of them with disclosed venture funding. Profound leads on capital, with $155M raised, including a $96M Series C in 2026. Incumbents are buying in: Adobe bought Semrush, Sitecore bought Scrunch, and HubSpot is bundling AI-visibility tracking into a platform buyers already use, which gives it distribution the standalone tools don't have. The criticism is forming just as fast: AI-visibility tools look commoditized, and their share-of-voice metrics are unstable. We've audited eight companies here.

Open question for founders
If every tool tracks the same prompts across the same engines, how do tools differentiate to compete?
