- Microsoft will support your business by giving you 3 years of access to development tools, such as Microsoft Visual Studio 2010.
- Microsoft will give you 3 years of rights to use their products for free in a production environment. This includes all flavors of Microsoft Server, but also products such as SQL Sever and SharePoint.
- You can access to VC, angel networks and other folk who would like to be involved in your startup.
It's a great program with few, if any, detractions (as far as I am aware). It doesn't cost anything to join Microsoft BizSpark, but you do need to get assessed and approved by an existing BizSpark Network Partner.
