Sharethrough

Independent omnichannel ad exchange known for native advertising innovation, ad quality, and sustainable advertising solutions, competing against larger SSPs and walled gardens

Sharethrough was an independent omnichannel ad exchange (acquired by Equativ in June 2024; brand unified under Equativ on June 9, 2025) specializing in native advertising technology and creative optimization. The company provides a supply-side platform (SSP) and exchange infrastructure that enables premium publishers to monetize their inventory while offering advertisers access to high-quality, non-intrusive ad placements across web, mobile, and connected TV environments. Sharethrough is particularly known for its proprietary Sharethrough Score, a creative quality metric that evaluates and optimizes ad creative performance in real time. Founded in 2011 and headquartered in New York, Sharethrough built its reputation on native advertising — formats that blend seamlessly with editorial content — before expanding into a full omnichannel exchange. The company's technology stack includes tools for header bidding, supply path optimization (SPO), and sustainable advertising initiatives, including its Green Media Products designed to reduce the carbon footprint of digital advertising. In 2021, Sharethrough merged with District M, a Canadian ad tech company, to form a combined independent exchange with significantly expanded scale and publisher reach. The merged entity operates under the Sharethrough brand and is considered a subsidiary of the combined organization. The company continues to differentiate itself through its focus on ad quality, sustainability, and publisher-first monetization strategies, positioning itself as a credible independent alternative to the major walled gardens in the programmatic advertising ecosystem.
