I'm not; I'm a useless academic. :) Many of the students in my program start small game companies, though (I teach in a game masters program), so I follow that scene a bit.
Most of the small tech companies I know are pretty low-key, though. Besides the game company route, another common one is a small team of 1-3 people making a living doing iPhone app development, that kind of thing. Some congregate around hackerspaces like: https://labitat.dk/
Not as much of the typical 'startup' route per se, although there have been a few (Unity3d and Bitbucket come to mind). There's also Copenhagen Suborbitals, which isn't for-profit, but is probably the most widely recognized organization to come out of the Copenhagen hacker/maker scene.
A few examples that have come out of the program here: http://conquistadorthegame.com/ http://machineers.tumblr.com/ http://www.knapnokgames.com/ http://gutefabrik.com/ http://duckandcovergames.com/ http://www.seriousgames.net/
