Synup
Synup is a local marketing and digital presence platform that helps agencies and multi-location businesses manage listings, reviews, and social media from one place. Founded in 2013 and headquartered in New York, the company started as a way to keep business location data accurate across hundreds of directories, then expanded into reputation management, local SEO, and AI-driven review responses. In 2025 it launched Synup OS (Agency OS), an operating system that adds CRM, sales pipeline, invoicing, and client-lifecycle tools so agencies can run their whole business - not just their clients' local presence - in a single platform.
