Marchex announced this afternoon that it has acquired VoiceStar, which provides pay-per-phone-call (PPCall) and call tracking services to a range of companies online and their advertisers. The reported acquisition/investment price is $28 million. VoiceStar is expected to generate $1.5 million for the full year 2007 and double that in 2008. However Marchex sees a much bigger opportunity in integrating VoiceStar’s technology and PPCall capabilities into its current advertising and search distribution platforms.
I have more detail on my personal blog.
