GPJ is an experiential marketing agency founded in 1914 in Detroit, Michigan, originally as a flag-making and sail-repair shop. The company now operates globally across North America, Europe, Asia-Pacific, and South America as part of the Project Worldwide network, designing integrated virtual, hybrid, and in-person brand experiences for major companies.
The agency's core offering centres on Strategic Experience Mapping, a proprietary process refined over decades to connect brands with their audiences through measurable experience programmes. This methodology underpins the company's work across traditional event production, virtual and hybrid experiences, and strategic experience design - fields in which it operates across multiple continents.
GPJ maintains a commitment to diversity, equity, and inclusion, alongside a stated culture of innovation and collaboration. The company invests in talent development through Ignite@GPJ, an apprenticeship initiative for emerging experiential marketers, and participates in Project Pledge, a corporate responsibility programme focused on social and environmental sustainability.
