QuinStreet is a performance marketing company that connects consumers shopping for financial and home services products with providers. QuinStreet operates on a cost-per-action model, charging clients only when it delivers measurable consumer actions, including clicks, leads, phone calls, applications, or completed transactions, rather than ad impressions. The company operates in two main verticals: Financial Services and Home Services. In Financial Services, QuinStreet primarily serves auto insurance carriers and agents through click marketplaces, lead generation, call distribution, and its comparison rating platform, alongside personal loan, credit card, and deposit offerings. In Home Services, QuinStreet connects homeowners with contractors for projects like roofing, HVAC, and solar through brands including Modernize and HomeBuddy. QuinStreet generates revenue by earning a margin spread between client payments per delivered action and media acquisition costs. The company acquires consumer traffic through third-party publisher revenue shares and higher-margin owned-and-operated media. QuinStreet relies on proprietary data and matching algorithms to route consumer traffic to clients, and pursues growth through digital marketing transition, product expansion, and acquisitions.
