Kiptronic, a San Francisco ad startup that inserts ads into audio and video files as they are downloaded, has raised a $3 million second round of funding, according to VentureWire.
The company’s technology also targets by the usual metrics — age, sex, geographic location, content type and so forth — and works across multiple device and file types. Kiptronic works with Akamai, and competes with companies including Podbridge (update: Podbridge is now known as VoloMedia).
The investors in the $3 million round were not named. Kiptronic’s first round of $4 million, from Blueprint Ventures and Prism VentureWorks, was disclosed in January of last year.
