What Knock Knock City does
Knock Knock City is a Minneapolis-based, private content platform that operates a free directory of luggage storage options for travelers. Founded in 2017, the company publishes SEO-optimized city guides covering 1,000+ luggage storage locations across 35+ cities in the United States and Europe, directing users to partner storage networks such as LuggageHero, Radical Storage, NannyBag, Schwartz Luggage, and HotelsHero. The site does not store luggage itself; it functions as a discovery and comparison layer, curating pricing, insurance terms, and cancellation policies across multiple storage providers.
The underlying technology is a content management system (WordPress-based, per the site's asset paths) without any disclosed proprietary features, API, SDK, or mobile application of its own. Distribution is organic — primarily search engine optimization, city-specific landing pages, and TikTok content — supplemented by a 2019 CNBC feature that boosted brand credibility. Knock Knock City has no disclosed funding, a headcount of 1–10, and no management team information publicly available.
The business model is purely affiliate/referral-based. The platform is free to end users; revenue is generated when visitors book luggage storage through partner links, primarily with LuggageHero, which is explicitly disclosed as an affiliate in the site footer. The company does not own inventory, does not process transactions, and does not charge consumers. Customer segments are individual travelers including tourists, layover passengers, cruise passengers, and local residents needing short-term bag storage. There is no evidence of enterprise customers, B2B contracts, or premium pricing tiers.
