It's worth noting that Quantrix Modeler [1] (founded in 2002) did carry on the torch after Lotus Improv, and continues to exist. That said, it's not clear how much traction Quantrix got either. It was bought out in 2010 by IDBS and te deal value wasn't disclosed, but it was reported that they had only nine employees at the time of acquisition. Another very interesting earlier attempt in this market was Javelin [2].
