Less than I'd like, actually — the scene is connected with Missoula's, but it seems to be a somewhat loose connection (despite the two cities only being a three-hour drive through beautiful country from each other).
They do have a solid community, though, from everything I've heard so far. http://Startupbozeman.com has some info, and I went to the HATCH conference this year (http://hatchexperience.org/) which takes place in Bozeman, and met some wonderful representatives from the city. Good people, a nice downtown, and though not QUITE as walkable or cheap as Missoula, it's absolutely beautiful over there, and I always enjoy a visit.
Not sure about the startup scene here, but the major tech employers I know about in Bozo are RightNow/Oracle, Zoot and Montana State University. Keep in mind, though, that one doesn't move to Montana for the salary. Also, real estate in the Gallatin valley is expensive compared to other places in MT. I moved back to MT (grew up in Butte) 2 years ago and while the salary isn't great, it beats the hell out of Los Angeles traffic.
