A viewer finds an online video, clicks play and increasingly, expects a TV-like experience. Hundreds of millions of times per day around the world, this sequence of events happens, and it's only growing in frequency. While surging demand is great for the overall ecosystem, network providers / broadband ISPs are continually struggling to keep up with spiraling traffic, pressed to invest in their networks to create more capacity while still maintaining a strong ROI.
Therefore, any incremental improvement in networks' efficiency in delivering video traffic can quickly add up to huge cost savings, and that's exactly what Qwilt, which has raised another $16 million (led by Bessemer Venture Partners and bringing to $40 million total raised to date), does. Qwilt is in the "transparent caching" business, with networks deploying the company's software solution on off-the-shelf hardware at the edge of their networks to deliver the thin slice of most-frequently viewed video to their users.
