Default a platform for finding other devs to collaborate is a free platform where you can look for others to collaborate on a startup, idea or project. It is ideal for indiedevs. You can also look for people that can promote your application etc. A fact is with more skilled people you can build better quality products in less time.

It's a bit like kickstarter only it is used for skill funding instead of crowd funding :P
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.

If you have any questions about it just ask!
