What CPMStar does

CPMStar is a Santa Monica-headquartered advertising technology company that operates a real-time bidding (RTB) platform purpose-built for the gaming and youth-oriented entertainment vertical, founded in the mid-2000s by Josh Goldstein. The company runs three interconnected modules: an SSP for Publishers (header bidding, direct campaigns, proprietary bidding technology, Prebid Adapter integration, In-Game API for intermission and rewarded video ads, and adblock-bypass technology), a Managed DSP for advertisers (end-to-end campaign management with real-time auto-optimization), and Integrated Marketing Services (fully managed media planning including programmatic guaranteed and direct IO for brands and agencies). Underlying technology includes proprietary bidding logic tuned for gaming inventory yield, machine-learning-based ad serving and rate optimization built over 15+ years of R&D, and connections to 45+ SSPs/DSPs including Verizon Media and IndexExchange.

CPMStar monetizes through three revenue streams: (1) publisher advertising fees via its SSP, taking a cut on impressions sold across ~2,000 publisher websites; (2) managed DSP services with hands-on campaign management for advertisers; and (3) integrated marketing services for brands and agencies. Pricing is quote-based and not publicly disclosed, with custom multi-year contracts at the enterprise tier. The go-to-market combines a direct enterprise sales team (targeting top game studios, agencies, and brands) with a self-serve publisher dashboard at dash.cpmstar.com. CPMStar reports scale metrics of 700+ partners, 4.7B annual page views, 1B unique visitors, and 24B+ annual impressions.

The company is privately held and was acquired by Aditude Inc. in 2024, following prior ownership by GSN (Game Show Network) from 2010 to 2018 and a buyback by founder Josh Goldstein in 2018. It currently operates as a subsidiary of Aditude, with headcount in the 11-50 range and offices across the United States and Europe. Named enterprise customers include Tencent, Wargaming, Amazon Games, NetEase, NCSOFT, Pearl Abyss, Wizards of the Coast, Nexon, and developers such as Stunlock Studios and Nexters; publisher partners include Armor Games, Ninja Kiwi, MMOBomb, CrazyGames, Chess.com, HLTV, and Valnet.
