Charles River Interactive

Based in Waltham, Massachusetts, Charles River Interactive is a small digital marketing agency working with clients across the country rather than a single regional base. Its client list spans automotive dealerships, security technology companies, and educational institutions, including work for Bernardi Honda Auto Parts, Duo Security, MIT Sloan, and MIT CTL. The agency positions itself as functioning like an extension of a client's in-house team, emphasizing collaboration to translate business goals into digital strategy rather than treating campaigns as isolated tactical work. Services described include search engine optimization, paid search, social media marketing, creative services, analytics, and web services, built around what the agency calls a search engine marketing core. Work is organized around strategy development that starts by identifying target audiences, followed by integrated campaigns intended to be data-driven and measurable. Documented project examples include a LinkedIn strategy for Duo Security aimed at increasing engagement and conversion, a webinar series produced for MIT Sloan Executive Education, and ecommerce strategy work with Bernardi Honda Auto Parts focused on fourth-quarter performance. The agency also references analytics as a component used to shape ongoing digital marketing decisions and to connect strategy to business outcomes such as lead generation and return on investment. Leadership includes a president, a head of client success, and two directors, reflecting the agency's small team size.
