Blackwave has raised $7 million in Series C funding from return backers Globespan Capital Partners, Flybridge Capital Partners and Sigma Partners, the Acton, Mass.-based company announced today, after being outed yesterday for an SEC filing that disclosed part of the round.
Blackwave has been around for quite a while, and had previously raised more than $22 million, but it brought in a new team this year and finally shipped its first product, the Blackwave R6, an appliance that uses hard disks optimized for video storage and delivery. The company said the new funding would be used to bulk up its sales force. Here’s an excerpt from our story on the R6, when the company signed CDNetworks as its first customer and said it would be courting wireless operators that need to build out video infrastructure:
By optimizing conventional disk drives for video, Blackwave can offer a viable and cheaper alternative to solid-state drives. It brings the price for delivering a 3.5 Mbps stream to under $20, said Kilian. Some of its special sauce is in the real-time scheduling of data as well as avoiding overprovisioning of disk space. Those tweaks improve on addressing some common strains induced by video — for instance, big bursts of concurrent watchers, or on the other hand, UGC that’s only seen by a few people.
Blackwave bragged today in an emailed press release that one R6 customer condensed its storage and delivery infrastructure from 20 racks to two, and another lowered planned infrastructure expansion costs by 70 percent.
