About Rhythmone, LLC

One targeted ad for the lady? RhythmOne (formerly Blinkx) serves up targeted adverts to online audiences across desktop and mobile video, rich media, display, social, and native formats. The company's primary product, RhythmMax, is a programmatic advertising platform with pre- and post-bid filtering technology that protects brand adverts from being displayed on undesirable webpages or other negative contexts. It has worked with brands including Honda, Nestle, Ford, and McDonalds. Headquartered in the UK, RhythmOne derives most of its revenue from the US. It was founded in 2004 by Suranga Chandratillake, former CTO of Autonomy Corporation, and changed its name from Blinkx in 2017 after the company completed its shift towards being a programmatic advertising company.
