Companies that use Fastly

Source: Analysis of job postings that mention Fastly (using the Bloomberry Jobs API)

My analysis reveals that Fastly is primarily purchased and evaluated by senior engineering leadership. Directors of Engineering (16%), Vice Presidents of Engineering (9%), and Platform Engineering leaders collectively represent over a third of decision-makers. These buyers are responsible for critical infrastructure decisions around CDN, edge computing, and perimeter security. They prioritize scalability, reliability, and developer experience, seeking solutions that can handle massive scale while enabling rapid deployment cycles.

Day-to-day users are predominantly DevOps Engineers and SREs (14%), along with platform engineers and full-stack developers who manage the technical implementation. These practitioners configure WAF rules, manage CDN routing, implement edge logic using VCL, and integrate Fastly with observability platforms like Datadog. They work hands-on with configuration management, DNS routing, security policies, and performance optimization across multi-region deployments.

The pain points emerging across these postings center on three themes: handling extreme scale, maintaining security at the edge, and enabling developer velocity. Companies describe needing to process "billions of requests per month," deliver "high-traffic web applications," and support "millions of users worldwide." They seek engineers who can "optimize caching, routing, and edge logic" while ensuring "robust protection against DDoS attacks" and maintaining "scalable, high-performance infrastructure." The emphasis on both security and speed reflects Fastly's positioning as a performance-focused edge platform for enterprise-scale applications.

I noticed that Fastly's customer base is remarkably diverse, spanning media companies like Spotify and Twitter to industrial manufacturers like JUMO and SÜSS, alongside retailers, healthcare providers, legal firms, and even non-profits. What connects them isn't a single industry but rather a common need: these companies operate digital properties that matter to their business. Media companies stream content, manufacturers provide technical documentation and e-commerce, service businesses run customer portals, and even traditional industries like construction firms and car dealerships maintain significant web presences.

The maturity spectrum is wide. There are obvious scale players like Spotify (17,645 employees), Twitter, and Bruker (publicly traded), alongside mid-stage growth companies like Xendit (Series D, $300M raise) and Holafly (600+ employees), down to small operations like TrueVoIP (4 employees) and local dealerships. However, even smaller companies often describe decades of history or significant regional presence, suggesting established businesses digitizing rather than pure startups.

I noticed that Fastly users are predominantly enterprise companies running complex, content-heavy digital experiences, particularly in retail and e-commerce. The massive overrepresentation of Adobe Commerce Cloud and Adobe Experience Manager tells me these are organizations managing sophisticated customer touchpoints across multiple channels. They're not running simple websites. They're orchestrating entire digital ecosystems where performance and content delivery are mission-critical.

The pairing of Adobe Commerce Cloud with Fastly makes perfect sense. E-commerce sites need lightning-fast page loads because every millisecond of delay costs conversions. When you're running an enterprise commerce platform serving millions of customers, a CDN like Fastly becomes essential infrastructure. Similarly, Adobe Experience Manager is a heavyweight content management system used by large organizations with complex governance needs. Companies using AEM typically have massive libraries of digital assets that need to be delivered quickly to global audiences, which is exactly what Fastly excels at.

The presence of Adobe Dynamic Tag Manager and Google Search Console points to companies deeply invested in digital marketing and SEO. These aren't just building products and hoping customers find them. They're actively managing their digital presence, tracking user behavior, and optimizing for search visibility. GlobalSign's appearance suggests these companies handle sensitive transactions and need enterprise-grade SSL certificates, reinforcing that we're looking at serious e-commerce operations.
