I have to work with other people and companies on almost all of my projects. Here are some the ones I like to collaborate with:

Meld
We work togheter on a lot of projects, both personal and business related. The best designer out there.

Felt
My main tech guy. His main target is to make better web. Can someone get this guy fired from his day job?? Just kidding. But I would want to work more with him. :)
Cobra
I work with Cobra on some projects where they need an Information architect. I enjoy working with them, because I always learn a lot from these people. And they are fun!

Jobi
Jo is soon lost as a potential freelancer, starting his career as a hired consultant. But I have a strong feeling he will come back.

Espen Dalløkken
Espen is an engaged developer who wants to create better web solutions. He has a high standard for himself, and is definately someone to learn from.

Urgle Network
A network of web developer, IA’s and designers, all wanting to make better web experiences.
