Fun facts about Fastly, Inc.

Quirks, history, and lore behind FSLY — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. technology company · mid-cap · listed on NYSE · headquartered in San Francisco, California.
2
The Numbers
Annual revenue in the low hundreds of millions of dollars, with a customer base heavily weighted toward large enterprise and media companies — think big traffic, big bills.
3
The History
Founded around 2011, it rode the wave of the modern internet's demand for real-time content delivery and went public in 2019 at a valuation that made Wall Street do a double-take.
4
The Secret
Unlike older rivals, it was built from the ground up around programmable edge infrastructure, letting developers push logic to the network itself rather than just files and images.
5
The Lore
Its stock famously surged over 500% in 2020 — then cratered just as dramatically — partly because one of its biggest customers, TikTok, faced a U.S. ban scare.
6
The Giveaway
Its ticker is a portmanteau of "fast" and a adverb suffix, its logo leans hard into speed, and its whole pitch is making the internet edge-delivered and blazingly quick.
