What Horizon Software does

Horizon Software, also operating as Horizon Trading Solutions, is a privately held electronic trading technology vendor founded in 1998 and headquartered in Paris, France. The company builds a single, integrated multi-asset electronic trading platform that combines an Order and Execution Management System (OEMS), a Smart Order Router (SOR), high-touch and low-touch execution, internalization and matching, market-making technology, and proprietary trading/arbitrage capabilities into one modular architecture. The platform supports equities, derivatives, structured products, DeltaOne, bonds, and digital assets, and connects to over 150 markets, brokers, data sources, and crypto venues. Clients can build proprietary trading strategies and execution algorithms on top of the core platform using the Horizon Extend development environment.

The firm sells primarily to enterprise financial institutions — banks, brokers, hedge funds, and exchanges — with named clients including HSBC, Santander, ING, Natixis, Nomura, Bank of East Asia, Saudi National Bank, BOCI, Arqaam Capital, EFG Hermes, Vontobel, Euronext, and the London Metal Exchange. Revenue is generated through three streams: (1) annual subscription licensing of the platform and its modular components, (2) managed services including high-performance hosting, application management, and 24/6 support, and (3) professional services for client onboarding, customization, and Horizon Extend implementations. Pricing is enterprise quote-based and not publicly disclosed.

Horizon operates across 26 countries with six staffed offices (Paris, Montreal, Hong Kong, Bangkok, mainland China, and Dubai) and reports approximately 100 employees supporting over 100 clients. The company holds SOC 2 Type II certification and has won recognition including TradingTech Insight's Best Platform for Electronic Market Making, FOW International Awards for Buy-Side and Multi-Asset Trading System of the Year, Bobsguide/FStech awards for Best Sell-Side EMS/OMS and Best Trading System, and SRP China awards for Best Technology Provider and Best Technological Solution.
