Direct Digital Holdings Inc (NASDAQ: DRCT) is a programmatic advertising technology company that operates both a sell-side platform and a buy-side advertising services business. Revenue comes from two streams: selling digital ad inventory through its proprietary Colossus SSP to demand-side platforms, agencies, and advertisers, and providing managed digital advertising campaigns to small and mid-sized clients through its buy-side brands, Huddled Masses and Orange 142. The company processed approximately 170.4 billion average monthly impressions in FY2025, reaching on average approximately 174,000 advertisers per month. DRCT focuses on underserved small and mid-sized clients across verticals including travel and tourism, higher education, energy, healthcare, financial services, and consumer goods. Revenue declined sharply from $157.1 million in FY2023 to $62.3 million in FY2024 and $34.7 million in FY2025, primarily due to a major sell-side customer pausing its connection in Q2 2024. The company reported a net loss of $27.7 million in FY2025. Mark Walker serves as Chairman and CEO; Keith Smith serves as President.

Revenue model

Transactional on the sell-side: DRCT earns revenue by purchasing digital ad inventory from publishers and reselling it to advertisers via the Colossus SSP programmatic platform. On the buy-side, revenue is earned through managed advertising campaign fees under insertion orders or master services agreements, with smaller clients on short-term arrangements and mid-sized clients on contracts ranging from one to five years (per FY2025 10-K).

Products and services

Colossus SSP: proprietary sell-side programmatic platform supporting display, OTT/CTV, in-app, native, online video, digital audio, and DOOH inventory. Buy-side managed advertising services offered through Huddled Masses (acquired 2018) and Orange 142 (acquired 2020), covering programmatic, social, paid search, mobile, native, email, video, OTT/CTV, audio, and DOOH channels. Supply Path Optimization (SPO) agreements providing custom data integrations and campaign transparency to agencies and advertisers.

Customers and end markets

Sell-side customers include DSPs, agencies, and individual advertisers, averaging approximately 174,000 advertisers per month in FY2025. Buy-side customers are approximately 195 small and mid-sized companies as of the FY2025 filing, spanning travel and tourism, higher education, energy, healthcare, financial services, and consumer goods. Large advertising holding companies managing multiple advertiser accounts are also served on the buy-side.

Value-chain role

DRCT operates at both ends of the programmatic advertising supply chain. On the sell-side it acts as a supply-side platform (SSP) intermediary between publishers and media buyers. On the buy-side it acts as a managed-service advertising agency and media buyer for small and mid-sized advertisers, positioning itself at the first dollar of spend prior to agency involvement in many cases.
