The Leader in Real-Time Messaging and Data Streaming

Lightstreamer is a global leader in real-time messaging and data streaming solutions. Since the beginning, Lightstreamer has been focused on real-time technologies aimed at making the Web a live environment, and superseding the traditional Web paradigm, where any update had to be “pulled” by the client rather than “pushed” by the server. Lightstreamer anticipated and helped develop new technology paradigms, such as Comet and WebSockets, and is now leading the real-time messaging space, including Mobile and the Internet of Things.

The Lightstreamer products have been used by a growing number of organizations, from startups to Fortune 500 enterprises, including top-tier financial institutions, as well as aerospace, defense, energy, gaming, sporting, media, and entertainment companies. In 2012, Weswit (the name of the Lightstreamer company at that time) was recognized as a “Cool Vendor in Application and Integration Platforms” by Gartner, the world’s leading information technology research and advisory company.

Lightstreamer has millions of end-users served by hundreds of customers worldwide, including NASA, Delta Airlines, Sky, eToro, Fidelity Investments, Fannie Mae, IG Group, Societe Generale, UBS, DNB, Intesa Sanpaolo, StoneX, Forex.com, OOCL, and many others.
