Muck Rack

Muck Rack

Gregory Galant and Lee Semel founded Muck Rack in 2009, initially as a tool to help journalists build digital portfolios using social-verification signals. The firm bootstrapped for years before raising its first institutional funding, a $180 million Series A from Susquehanna Growth Equity in 2022 (per the firm, September 2022). The original journalist-facing product remains live and drives the freshest, most validated media-contact database in the market — their structural advantage is that the database is populated and maintained by the journalists themselves, not scraped by an internal data team. Muck Rack's platform covers media monitoring, PR measurement, and journalist database management for communications teams. The firm processes monitoring across digital news, broadcast, newsletters, and podcasts, integrated with a CRM-like contact database verified by AI that scores journalist responsiveness and topic expertise. Its analytics module replaces legacy measurement standards like AVE (Advertising Value Equivalency) with quantitative metrics on share of voice, sentiment, and message pull-through. The firm competes directly with Cision and Meltwater but differentiates by refusing to sell contact-list downloads, requiring instead that users email through the platform — ensuring journalists get relevant, non-spammy pitches. Confirmed enterprise clients include Duolingo, Zapier, and the Susan G. Komen Foundation. From its Miami headquarters, Muck Rack employs a remote-first team with a concentrated presence in Florida and New York. In September 2022, the firm accepted a minority growth investment of $180 million from Susquehanna Growth Equity, its first outside capital after 13 years of bootstrapped profitability (per the firm and Axios, September 2022). The capital was earmarked to accelerate product development in generative AI and expand the executive-tier analytics offering. The founding pair retain control, with Galant continuing as CEO building on the thesis that earned media measurement is a software problem, not a services business. Muck Rack's structural differentiator is the bidirectional model: the journalist-facing side of the platform generates the freshest media database in PR tech, making the buyer-side product self-improving. No competitor replicates this loop because it requires maintaining a free product that gives journalists direct value — verified profiles, portfolio pages, and pitch controls — which in turn produces the data foundation that justifies enterprise pricing on the PR side. This architecture creates a data moat that grows more defensible as the number of active journalist users scales.
