RomperJack monetizes through an e-commerce model as it predominantly operates as an online retail business. By selling men's rompers and jumpsuits directly to consumers through its Shopify-powered online store, the company leverages a platform that allows for global reach without the need for physical retail space. This model is especially suited for niche fashion products like male rompers, which initially faced little competition and required a broad audience base to validate market interest. The choice of e-commerce enables RomperJack to maintain lower overhead costs and offers scalability as the brand expands its product line to other apparel items.

While not directly related to RomperJack, Justin Clark has previous experience in this space with Whiz Tutor, an app designed to connect students with local tutors. Although Whiz Tutor operates within the education sector, it shares similarities with digital marketplaces due to its platform-based model. The foundational skills and network developed through Whiz Tutor laid the groundwork for launching RomperJack, highlighting a diverse business acumen that spans both fashion and technology sectors.
