Direct Digital Holdings, Inc.

Direct Digital Holdings, Inc. is an end-to-end, full-service advertising and marketing platform providing advertising technology, data-driven campaign optimization, and other solutions. The company helps brands, agencies, and middle market businesses achieve successful marketing results and drive return on investment across both the sell- and buy-side of the digital advertising ecosystem. Incorporated in Delaware on August 23, 2021, and headquartered in Houston, Texas, Direct Digital Holdings is the holding company for DDH LLC. DDH LLC was formed in 2018 through the acquisitions of Colossus Media and Huddled Masses. The company operates two main business segments: sell-side advertising and buy-side advertising. Its sell-side advertising business, operated through Colossus Media, provides a proprietary programmatic platform under the trademarked banner of Colossus SSP™. This platform automates the sale of ad inventory, leveraging proprietary technology to help advertisers of all sizes, including brands, media holding companies, independent agencies, or emerging businesses, reach audiences and curated creators. It also helps publishers find brands for their readers and drives advertising yields across web, mobile, and connected TV (CTV) channels. The buy-side advertising business, now operating as Orange 142, provides technology-enabled advertising solutions and consulting services to clients. This segment utilizes multiple leading demand-side platforms (DSPs) and serves various industry verticals such as travel and tourism, higher education, energy, healthcare, financial services, and consumer products. It particularly focuses on small and mid-sized businesses transitioning into digital advertising with growing digital media budgets. DDH LLC acquired Orange 142 in September 2020 to bolster its programmatic buy-side advertising platform. In October 2024, the company announced the unification of its buy-side businesses, Orange 142 and Huddled Masses.
