Who is Fastly's CEO?

Kip Compton has been CEO since June 2025. He previously served as Fastly's chief product officer and earlier as a senior executive at Cisco.

Artur Bergman founded Fastly in San Francisco in March 2011. Bergman had been CTO at Wikia and saw that existing CDNs were built for static file delivery of a previous web era, unable to handle dynamic, personalized, API driven content. He built Fastly on Varnish, an open source caching engine, exposing it as a programmable platform developers could control in real time.

The company's early customers were exactly the technical organizations it was designed for: developers at Github, Twitter, and media properties adopted it for the instant cache purging and API control that legacy CDNs could not match. Venture rounds through the decade funded network expansion: $10 million Series B in 2013, $40 million Series C in 2014, $75 million Series D in 2015.

Fastly went public in May 2019 on the NYSE, riding demand for edge infrastructure. In 2020 it made its largest acquisition, buying security vendor Signal Sciences for approximately $775 million to add a web application firewall and API protection layer. That deal defined the modern product: delivery plus security plus compute at the edge.

Leadership turned over repeatedly. Bergman stepped down as CEO in February 2020, handing the role to Joshua Bixby, then Todd Nightingale in August 2022, then Kip Compton in June 2025. Bergman returned to a technical role as founder and CTO in April 2024.

The transformation under Compton produced fiscal 2025 results the market read as an inflection: record revenue of $624.0 million, record gross margins, and the company's strongest security growth, with AI workload demand emerging as a new driver. The company remains GAAP unprofitable but narrowed losses 23 percent year over year.

Fastly's most significant public incident was the June 8, 2021 outage, when a customer configuration change triggered a software bug that took down major portions of the internet, including Amazon, Reddit, and government sites for roughly an hour. The company disclosed the root cause transparently and resolved it without lasting reputational damage.
