GameScorekeeper is a Danish B2B esports data specialist founded in early 2016 by Felix Klastrup in Aarhus, Denmark. It provides high-integrity, structured data feeds, widgets, and white-label solutions to sports betting operators, fantasy sports platforms, and media companies. The company’s proprietary platform automatically collects and normalizes millions of data points per event across over ten leading esports titles, including CS:GO, League of Legends, Dota 2, Valorant, and Overwatch. Its product suite includes historical, scheduling, and live data delivered via REST and WebSocket APIs, as well as embeddable visualizations and fully branded turnkey esports websites. GameScorekeeper also offers compliance solutions tailored for esports sportsbooks. The company has established partnerships with major industry players such as DraftKings, PrizePicks, and Pinnacle, and in 2021 partnered with Sportsflare to launch the first esports Bet Builder. In November 2025, GameScorekeeper was acquired by Oddin.gg, combining its extensive data archive with Oddin.gg's real-time predictive models and managed betting services. The acquisition positions the combined entity as a comprehensive end-to-end esports data and betting infrastructure provider.
Detailed Review
History and Founding
GameScorekeeper was founded in early 2016 in Aarhus, Denmark, by Felix Klastrup with the vision of making esports data accessible and actionable for businesses. The company quickly established itself as a reliable data layer between raw tournament information and commercial applications, automating the collection and normalization of millions of data points per event from thousands of matches across more than ten esports titles.
Business Model and Products
GameScorekeeper generates revenue through subscription-based data packages and white-label solutions. Its core offering is the Esports Data Platform, which provides historical data for fantasy and odds modeling, scheduling and resulting data, and live play-by-play feeds via REST and WebSocket APIs. The company also offers Esports Widgets – embeddable visualizations such as match calendars, standings, and live scoreboards – and White-Label Esports Websites, fully branded portals launched with minimal development effort. Additionally, GameScorekeeper provides Compliance Solutions to help sportsbooks meet regulatory requirements for esports betting content. In 2021, through a partnership with Sportsflare, the company introduced the first esports Bet Builder, enabling combination markets for CS:GO, League of Legends, and Dota 2.
Market Position and Partnerships
GameScorekeeper’s client list includes major names like DraftKings, PrizePicks, and Pinnacle, who highlight the company’s responsive support and adaptability. The company also partnered with Scientific Games (now part of Light & Wonder) to expand into the esports market, and with Sportsflare to distribute AI-powered odds. The acquisition by Oddin.gg in November 2025 represents a consolidation trend in esports data, combining GameScorekeeper’s deep historical archive with Oddin.gg’s real-time predictive models and managed betting services. While the acquisition has likely shifted the company’s standalone identity, its products and team continue to operate under the Oddin.gg umbrella.
