... with the acquisition of Optimost by Interwoven. This is an interesting acquirer for an MVT firm - only yesterday at E-metrics, I was saying to someone that until MVT was a built-in option in content management systems that essentially allows users to press a button and have the site "deliver the best content/layout", it will always remain something of a challenge for many people. So clearly Interwoven have seen the opportunity to add value to their CMS platform by embedding this kind of capability.
This means that the MVT market is starting to really tighten up. Offermatica and Optimost (the two biggest players in this market) have both been acquired recently, with Kefta acquired earlier in the year by Acxiom. This really only leaves Memetrics, SiteSpect, Vertster and Widemile as independents. It looks like this market could disappear before it's really got started.
