9thWonder
9thWonder was a Houston-headquartered strategic marketing, media and creative agency launched under that name in 2018 and acquired by Gravity Global in 2023. Jose Lozano built the organization by acquiring and integrating several independent agencies under The Company before consolidating the group into the 9thWonder brand. At launch, 9thWonder had seven offices, more than 250 employees and more than 100 clients, with services spanning media planning and buying, branding, advertising, lead generation, marketing automation, public relations, social media, content strategy, digital development, SEO, analytics and experience design. Its offices included Houston, Dallas, Denver, Los Angeles, New York, Buenos Aires and Nha Trang. The agency worked with brands including Direct Energy and Phillips 66 during its early unified-agency period. Gravity Global acquired the remaining 9thWonder organization in 2023 after previously acquiring its B2B unit in 2022. The transaction added roughly 250 employees to Gravity Global and expanded the combined organization to more than 500 specialists across 14 locations. The former 9thwonder.com domain now redirects to Gravity Global, reflecting the completed integration.
