Peer5 offers a WebRTC based P2P eCDN that runs in-browser to solve congestion issues. Our mesh networks are self-balancing and automatically scale as the number of viewers rises. Since it is a WebRTC based eCDN it doesn't require any installation on end-users computers nor changes to the physical network infrastructure. Instead, we integrate with any existing player within the event web page. Peer5 was designed from scratch for WebRTC, written completely in JavaScript. We contribute to the WebRTC community and are active members of the W3C steering committee. Peer5 is backed by Y Combinator and additional top Silicon Valley investors.
