Qwilt, a firm that specializes in online video delivery and transparent caching, has sealed up a $16 million Series C round led by Bessemer Venture Partners, with help from current investors Accel Partners, Redpoint Ventures and Marker LLC
With previous rounds factored in, Redwood Shores, Calif.-based Qwilt has raised about $40 million.
Qwilt said the funds will be used to expand its international sales and engineering teams and to shore up its flagship product, the Qwilt QB-Series Video Fabric Controller, a platform that monitors video traffic on operator networks, identifies popular and trending titles, and then stores those titles at the subscriber edge to help partners save on online video transport costs.
Qwilt holds that the approach reduces network traffic and congestion by eliminating the need for replicating content streams from origin servers or content delivery networks.
Among recent wins, Choice Cable of Puerto Rico tapped Qwilt’s platform to address demand for over-the-top video across its network. In May, Qwilt formed a technology partnership with CDN provider Limelight Networks.
