What Parallel 42 does

Parallel 42 is a privately held, founder-led developer of add-on software, scenery, and vehicles for consumer flight and driving simulators, with a parallel branded merchandise line. The company builds products for Microsoft Flight Simulator 2024 and 2020, American Truck Simulator, and legacy Lockheed Martin Prepar3D / FSX platforms, sold as one-time digital licenses through its own e-commerce storefront. Core software titles include ChasePlane (a camera and viewing tool with trademarked features such as Let's Go Spotting), Skytrails (flight trail visualization), Sunset Strip / 42SS (scenic scenery), GoFish (a data-driven fishing experience), and Hogsback Ranch (American Truck Simulator scenery). Underpinning these is Flow Pro, a custom scripting framework with widget extensibility that has begun hosting third-party integrations such as the SayIntentions.AI widget.

The business model combines direct-to-consumer e-commerce across 17+ currencies, branded apparel and accessories (caps, beanies, bomber jackets, patches) produced and fulfilled through Fourthwall's print-on-demand infrastructure, and a recurring Club 42 membership with subscription billing. Go-to-market is product-led and community-driven: marketing channels consist of the company's own website/blog, an active Discord server, an email newsletter, and annual participation in FlightSimExpo as an exhibitor. The company lists a Santa Monica, California mailing address but explicitly notes that Terms of Service target a US audience while shipping and pricing support a global customer footprint spanning North America, Europe, Asia-Pacific, the Middle East, and South America. No venture capital funding, acquisitions, or institutional investors are identified, and headcount is not publicly disclosed; the team self-describes as technologists united by a shared interest in flight and visual simulation.
