While Salesforce.com has been an active investor in startup companies for years, it's taking these efforts to the next level with its first dedicated venture capital fund. The Salesforce1 Fund will initially invest $100 million in emerging companies over the next few years, said John Somorjai, executive vice president of corporate development and strategy. The fund will focus on new mobile application startups that are building products on the vendor's Salesforce1 platform, Somorjai said.
