This group is for startups building on the Microsoft platform. You may be part of the Microsoft BizSpark startup program but this is not necessary to join. This group will share in our experience with being a startup based on the Microsoft platform and related technologies (.Net, Azure, Silverlight, etc. - you name it). Note: this group is not affiliated with Microsoft, though it was started by a BizSpark member startup and we are big fans!
BizSparkSF is now a BizSpark Network Partner and can recommend startups for the BizSpark program. Please contact the organizers for more information and to apply. Use the email form http://www.bizsparksf.com/members/12937680/
