Fastly, Inc.

Fastly is an edge cloud platform founded by Artur Bergman in March 2011. Bergman came to it from the CTO role at Wikia, where he managed traffic for millions of wiki pages, and built the company around a specific gap: content delivery that could accept real-time configuration changes and instant cache purging at global scale.

The technical breakthrough was making dynamic content behave like static content. Traditional CDNs took minutes or hours to propagate cache updates globally; Fastly introduced instant purging through its Surrogate Keys system. When an e-commerce site updates a product price, the affected content can be purged across the entire global network in under 150 milliseconds.

The platform is built around Varnish Configuration Language (VCL), which gives developers programmatic control over how content is cached and delivered. That made the edge itself programmable: custom logic for routing, security, and content transformation executes at edge locations worldwide.

Fastly is publicly traded (NYSE: FSLY) and serves media companies and e-commerce platforms that absorb large traffic spikes during events such as Black Friday. The platform now spans content delivery, security, compute, and observability, on the premise that modern applications need real-time control over global infrastructure.

The positioning is developer-first, paired with enterprise security and observability tooling: running complex applications at the edge with data-center-level control, rather than only moving content closer to end users.
