What Linkhouse does
Linkhouse, founded in 2014 and headquartered in Katowice, Poland (operating as the legal entity Grupa KBR Chlewiński i Kozłowski S.K.A.), runs a content marketing and link building marketplace that connects advertisers seeking SEO backlinks with publishers monetizing website inventory. The platform serves two primary customer segments: brands, agencies, and SEO professionals purchasing backlinks, and website owners selling guest posts, link insertions, and advertising banners. With a database of 79,228 publisher websites across 25 languages, Linkhouse facilitates approximately 9,700 publications monthly and processes over $5 million in annual marketplace GMV.
The core technology stack combines a two-sided marketplace database with a set of integrated AI-assisted tools. The proprietary Link Planner uses a custom Link Score spanning 30+ parameters to automate campaign planning, subpage and keyword selection, and budget allocation, generating executable campaigns in under a minute. Complementary modules include Backlink Gap (competitive link analysis), a Topical Backlinks Tool, an SEO Backlink Finder, and a Surfer AI integration for content optimization. Linkhouse has built free integrations with major third-party SEO platforms — Ahrefs, Semrush, Majestic, and Surfer (plus Semstorm) — embedding their domain metrics directly into the marketplace interface. In 2024, the company launched a ChatGPT Plugin that exposes Link Planner functionality conversationally within OpenAI's platform, and explicitly repositioned the offering to cover AI-search visibility across ChatGPT, Perplexity, Claude, and Gemini.
Linkhouse's revenue model rests on marketplace transaction fees supplemented by usage-based Link Planner credits priced at $22 each. Registration is free with no subscription required, supporting a self-serve product-led growth motion complemented by dedicated account managers for agency clients (with claimed time savings of up to 40%). Distribution is primarily direct through the online platform (app.linkhouse.co), augmented by an affiliate/referral program and content marketing via a Polish-language and English-language blog. Geographic footprint includes a registered US office in Dallas, TX alongside Polish operations, with global marketplace coverage. The company employs 11-50 staff, has no disclosed external funding rounds, no M&A activity, and no leadership changes in the source material.
