The company publishes a regularly released digital B2B magazine covering the full range of the global maritime industry — shipbuilding, ship management, ports and terminals, towage, and environmental awareness — accompanied by a continuously updated website with news, company profiles, and shareable digital brochures. The publication is part of a group of seven vertical B2B titles under Proactive Publications Ltd (alongside Inside Sustainability, Inside Mining, Inside Food and Drink, Inside Oil & Gas, Inside Technology, and Inside America), enabling shared back-office and cross-vertical advertiser relationships.

The core product is the Inside Marine Magazine, distributed as a digital publication accessible online and on mobile devices. The company also operates an in-house creative team of writers and graphic designers producing sponsored articles, company profile brochures, and advertisements in sizes ranging from quarter-page A4 to four full A4 pages. Distribution channels include the website, an email newsletter, a LinkedIn presence, and active media coverage of major international maritime exhibitions (Posidonia, SMM, APM, Nor-Shipping, Oceanology, Monaco Yacht Show, INAMARINE).

The business model is sales-led and advertising-driven, with revenue streams from magazine advertising, sponsored editorial articles (convertible into digital brochures), digital magazine subscriptions, copyright licensing of articles for advertiser reuse, event media partnerships and sponsorships, and a marketing services suite covering social media campaigns, email campaigns, brochures, product reviews, and web advertising. The go-to-market is relationship-based, leveraging brand recognition in the maritime vertical, a large portfolio of advertiser logos across shipping lines, ports, shipbuilders, and marine service providers, and physical presence at key industry events where decision-makers congregate.
