It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.

History & Notes
Instart Logic was a notable CDN player, raising $167 million across multiple funding rounds from investors like Andreessen Horowitz and Kleiner Perkins. Its Digital Experience Cloud used AI and machine learning to optimize content delivery, particularly for e-commerce and media companies. The 2020 acquisition by Akamai included customer contracts and IP, primarily to enhance Akamai’s page integrity solutions. No official EOL notice remains publicly accessible, but Akamai’s press release confirms the transition (https://www.akamai.com/newsroom/press-release/akamai-technologies-acquires-customers-and-select-intellectual-property-from-instart).
Viblast was recognized for its innovative use of WebRTC for P2P video streaming, winning awards like the Streaming Media European Readers’ Choice for Delivery Network in 2014. Its technology was particularly suited for large-scale live streaming, claiming up to 90% bandwidth savings. No official EOL announcement was found, but PitchBook data confirms the company ceased operations by March 2023. No evidence of asset sales or successor entities exists, and its website (viblast.com) is no longer active.
