Sapient has been caught up in its options issues, leading to a change in executive management and board (I had some dealings with the new CFO, Joe Tibbetts a long time ago at PwC. He was recently CFO at Novell, which acquired Cambridge Technology, long a Sapient Boston based peer firm).
Somehow, I think it will ride this change out reasonably well. It is a firm which has survived, and thrived some pretty wide swings in its focus areas and business model. It started life as a custom development shop which won clients with fixed price bids when most of the industry avoided those. It then took advantage of the e-business boom in the late 90s. It survived the services nuclear winter in the early part of this decade by aggressively growing an India center. Now as web advertising and digital "experience" marketing booms, it is poised to take advantage of that market.
