Third Door Media

What Third Door Media does

Third Door Media is a B2B marketing education, publishing, and lead-generation company founded in 2006 and headquartered in Boston, Massachusetts, that operates a portfolio of digital-marketing media brands — Search Engine Land, MarTech, Search Engine Roundtable, and Digital Marketing Depot — and runs the SMX (Search Marketing Expo) and MarTech Conference event series. Its core asset is an audience of more than one million digital marketers per month, supported by 170,000+ newsletter subscribers across MarTech, MarTech FYI, Search Engine Land, Search FYI, and Search Engine Roundtable, plus 11,000+ paid registrations across MarTech Spring and Fall digital events in 2023. The company does not develop software; its core technical footprint consists of owned websites, newsletter infrastructure, event platforms, and proprietary audience engagement data accumulated over 12+ years.

Revenue is generated through four primary streams: (1) event sponsorships across SMX Advanced (in-person), SMX Next (digital), and MarTech Spring and Fall (digital) with guaranteed-lead mechanics; (2) lead generation and content syndication programs, including MarTech Intelligence Reports buyer's guides with full-page ad placements; (3) digital display advertising and email promotions across all owned newsletters; and (4) a Content Studio producing custom articles, white papers, surveys, and webinars. Pricing is fully quote-based — there is no publicly disclosed price list — with multi-component programs assembled by account executives for B2B clients, primarily marketing technology vendors, agencies, and software companies. The company distributes exclusively through a direct-sales motion and a structured website inquiry form. Audience surveys cited on the site indicate 74–79% of MarTech Spring attendees have buying authority or are actively in-market, and 89% of MarTech readers and attendees influence purchasing decisions, with an average stated intent to purchase 7.8 platforms or services in the next 12 months. Customers include Salesforce, Snowflake, Conductor, Bruce Clay Inc., BlueConic, DemandJump, and Cloudinary. In October 2024, Third Door Media was acquired by Semrush (NYSE: SEMR) for an undisclosed sum and continues to operate its brands as standalone properties.
