Muck Rack is an American software company that develops an AI-powered, cloud-based public relations management (PRM) platform. Founded in 2009 by Greg Galant and Lee Semel, the company began as a free online directory for journalists to create portfolios and track engagement of their work. It later evolved into an integrated software-as-a-service (SaaS) platform used for media relations, monitoring, analytics, and press release distribution. The company expanded its AI initiatives through strategic leadership hires and acquisitions.

The company's name references the term "muckraker", used for reform-minded journalists during the Progressive Era.

Muck Rack was founded in 2009 by Greg Galant and Lee Semel. More than 10,000 journalists signed up in the platform's first year. In 2011, after observing PR professionals using the site to find journalists, the company introduced its first paid SaaS product.

In September 2022, Muck Rack announced a $180 million Series A investment led by Susquehanna Growth Equity, one of the largest investments in the PR technology sector.

In September 2024, Muck Rack acquired Keyhole, a Toronto-based social listening and analytics platform, adding real-time monitoring across major social platforms.

In January 2025, the company acquired Ruepoint, an Ireland-based media intelligence firm.

Muck Rack's platform supports media monitoring, outreach, workflow automation, and analytics, with heavy use of AI and machine learning.

The platform provides a media database of journalists, podcasters, freelancers, and outlets, along with AI-powered journalist recommendations.
