Teamups.net is a free platform where you can look for others to collaborate on a startup or idea. It is ideal for indiedevs. You can also look for people that can promote your application or company or look for script writers etc.
It’s a bit like kickstarter only it is used for skill funding instead of crowd funding 
With this service I hope to bring creative people together and create some awesome indie stuff. It just started last week and is still a bit in Beta phase but all basic functions to find people for your idea are working. I still have a lot of plans for improving the service, but I first need to know if people are interested in a concept like this before I start spending even more precious hours in developing this.
