We had a conversation with our BizSpark manager and you can also apply for BizSpark plus. This needs an additional review of your Startup, but if you succeed you get 10.000$ (or 15.000$ - not sure anymore) in Azure credits every month.
Quite nice to get some traction at the beginning :-)
Also the front page says only startups who are members of designated startup-accelerator programs can apply, though it's entirely possible that could be waived by your BizSpark manager.
@darklegend - my startup is already part of the BizSpark program, but it seems that the "Plus" program means that you have to go through an accelerator first. Is this requirement still valid - would have loved to apply directly (our core target market includes Windows Desktop software as well)
