It just so happens that Interwoven and Vignette are both looking. Vignette's Thomas Hogan is moving on to HP Software (one of the companies occasionally rumored to acquire a content management vendor), while Interwoven's Martin Brauns is retiring, for the 2nd time. Both announcements came today, when simultaneously both companies reported decent Q4 earnings (Vignette, Interwoven), rounding out successive years of steady but very modest growth. Hogan and Braun are respected in the community, but perhaps it's a good time for change at both companies. Neither vendor can seem to break the $200m annual revenue barrier, and as CMS Report readers know, their flagship Web content management tools remain the weaker links in their ECM product suites.
