Reviews Startups funded by Y Combinator (YC) 2026

AI assistants are replacing search for local businesses. When someone asks ChatGPT for a plumber or hotel recommendations, reviews are the primary training signal, especially in local markets where other data is sparse. This is GEO (Generative Engine Optimization). Cheers is the full-stack GEO platform for local service businesses. We audit AI visibility, build optimization plans (schema markup, citation fixes, review strategy), and give frontline teams NFC tools to generate reviews with employee-level attribution. Vivint generated 70,000+ five-star reviews in 5 months. They now rank #1 on ChatGPT and Google Search across their markets.
