Actually, the original Minecraft project was a collaboration between Mojang, koalaexpert and suparMacho (now "TheNerd" and "Michael"). They had posted a project before and gathered many supporters, and Mojang noticed the project. Mojang then offered the two users the chance to be part of a collab project.
