Case Study: SeenThis achieves faster, more sustainable ad streaming with Fastly

Fastly enables SeenThis to meet clients' tough sustainability targets and performance needs

SeenThis, the Stockholm-based ad streaming company, needed a faster, more customizable CDN than Amazon CloudFront to support its proprietary adaptive streaming and deliver instant-loading ads at global scale. The company also faced challenges with aging logging and monitoring tools, and later needed better reporting to prove the data and sustainability impact of its campaigns. Fastly helped SeenThis meet those performance and observability requirements with Fastly CDN and Fastly Logging.

With Fastly, SeenThis moved to a highly configurable setup using VCL, improved latency from 50 milliseconds to 5 milliseconds, and began handling more than 4 petabytes of data per month through Fastly. Fastly also enabled near real-time log streaming to BigQuery, giving SeenThis granular reporting by client and campaign and allowing it to calculate data transfer per ad. The result was a scalable system that supports both performance and sustainability goals, with SeenThis now sending 40%–50% less data than conventional methods.
