Company history

F5 was founded in Seattle in 1996 by Jeff Hussey, Mike Almquist, and Adam Feuer. After initially exploring virtual-reality gaming, the founders pivoted to managing internet traffic and developed BIG/ip, an early product for directing application traffic.[38] F5 completed its initial public offering in June 1999.[39]

During the 2000s and early 2010s, F5 broadened its offerings through acquisitions: MagniFire Websystems in 2004 added web application security technology, and Acopia Networks in 2007 expanded its reach into file virtualization and storage networking.[40][41] In 2012, it acquired Traffix to add telecom signaling capabilities, followed in 2013 by LineRate Systems, which brought software-defined networking technology.[42][43]

François Locoh-Donou became president and CEO in April 2017, succeeding John McAdam.[44] F5 completed its acquisition of NGINX in 2019, extending its capabilities in modern application delivery, and acquired application security company Shape Security in 2020.[45][46] In 2021, it acquired Volterra to expand into edge and distributed cloud services; that year, the company also adopted the name F5, Inc., replacing F5 Networks.[47][48]
