The New York company that turned messy business listings into an operating system for agencies.
A wrong phone number is invisible - until it costs you customers.
Synup is a local marketing platform. In plain terms, it makes sure a business looks the same everywhere online - the same name, address, phone number, and hours across Google, maps, directories, and dozens of other places customers check before they walk in or call. That sounds trivial until you run more than one location, at which point the small inconsistencies multiply into a real problem: profiles drift, duplicates appear, reviews pile up unanswered, and local search quietly stops sending people your way.
Founded in 2013 and headquartered in New York, Synup grew out of a marketing consultancy where the founders kept watching clients struggle with exactly this. The company built a single dashboard to push accurate location data out to a wide network of publishers, monitor and respond to reviews, schedule social posts, and track how a business ranks in local search. Over time it added AI that drafts replies to reviews and analyzes customer sentiment, always with an approval step so brands keep control of what gets posted.
In 2025 the company took a bigger swing. It launched Synup OS, also called Agency OS - an attempt to run not just a client's local presence but an agency's entire business, from lead to pipeline to invoice to upsell, in one place.
Synup's primary customer is the marketing agency - SEO shops, web design firms, and advertising agencies that serve local and multi-location businesses. Around that core sit franchises, multi-location brands, and channel partners like web hosts, telecoms, vertical SaaS companies, and payment processors that resell Synup's tools under their own branding. Together these partners manage millions of business locations through the platform.
The problem underneath all of it is fragmentation. A restaurant group with 40 locations might exist on a hundred directories, each with its own quirks and its own stream of reviews. Keeping that accurate by hand is impossible, and getting it wrong is expensive: inconsistent listings suppress local search rankings, and unanswered reviews erode trust before a customer ever makes contact. Synup's job is to make that whole tangle manageable from one login.
“Synup emphasizes agency- and SMB-friendly local listings, review monitoring, and multi-location workflows.”
Distributes and syncs accurate location data across a broad network of directories, maps, and publishers, with automated updates and duplicate suppression.
Monitors reviews across sites, surfaces sentiment analytics, and generates or automates responses - including AI-driven replies with approval workflows.
Local search optimization, audit tools, and visibility tracking to improve how a business appears in local results.
Schedules, publishes, and analyzes social content across multiple locations and channels from one dashboard.
An operating system for agencies: CRM, lead gen, sales pipeline, invoicing, payments, white-label client portals, churn forecasting, and upsell tooling.
Reseller and white-label options plus integrations that let partners embed Synup's local-marketing tools inside their own products.
The local-presence market is crowded - Yext, Birdeye, Podium, SOCi, Uberall, Moz Local, and others all compete for versions of the same job. Synup's distinction is where it points. While Yext built its business around enterprise brands with a large publisher network and deep data integrations, Synup went after agencies and small-to-mid businesses with flexible contracts, lower entry pricing, and white-label branding.
Agency OS pushes that difference further. Most competitors sell a better tool; Synup is trying to sell the agency a way to run its business - measuring not just listings and reviews but pipeline, retention, and revenue. Whether that consolidation wins is an open question, but it is a genuinely different bet.
Synup runs on B2B SaaS subscriptions, sold in tiered plans to agencies and multi-location brands, with per-location and add-on fees plus a partner/reseller program. Agency OS extends that revenue into CRM, billing, and payments - deepening how much of an agency's workflow lives inside Synup.
Its expertise is local: the unglamorous, high-consequence work of keeping business data accurate across a fragmented web, layered with reputation and, increasingly, AI. In the broader market, Synup sits in the local-marketing and digital-presence category - not the biggest enterprise name, but a well-rated challenger (roughly 4.5/5 across major review sites, a recognized G2 High Performer) that has carved out the agency-and-SMB middle of a large market.
