Fanout was a technology company that specialized in providing real-time messaging infrastructure for developers. Their platform enabled businesses to easily build and scale applications requiring live data push, such as chat, live updates, data broadcasting, and real-time APIs using WebSockets, Server-Sent Events (SSE), and HTTP streaming. Founded in 2013, Fanout empowered developers to focus on application logic rather than complex real-time infrastructure. In March 2022, Fanout was acquired by Fastly, Inc. to integrate its technology into Fastly's edge cloud platform, enhancing Fastly's offerings in real-time and event-driven services.
Served as the primary center for Fanout's operations, including product development, engineering, business strategy, and administration prior to its acquisition by Fastly.
As a startup, Fanout's headquarters likely featured a collaborative and agile workspace optimized for innovation and rapid development, characteristic of tech companies in Silicon Valley.
Fanout likely fostered an energetic startup culture characterized by innovation, engineering excellence, close-knit teams, and a strong focus on solving complex technical challenges in real-time messaging and API services.
Being located in Menlo Park provided Fanout with strategic advantages, including access to a rich talent pool, proximity to investors, and immersion in a vibrant tech ecosystem conducive to growth and partnerships.
Prior to its acquisition by Fastly, Fanout's services were designed for global accessibility, enabling developers and businesses worldwide to utilize its real-time messaging infrastructure. While its physical operations were primarily based in the United States, its platform and APIs catered to an international customer base needing to build and scale real-time applications. Following the acquisition, Fanout's technology has been integrated into Fastly's extensive global edge cloud network.
