Santa Monica-based Nimble, the customer relationship management and contact management software developer headed by Jon Ferrara, has snagged a high profile hire this morning, hiring former Salesforce Director of Mobile Product Jason McDowall as its new Director of Product. Nimble said that McDowall will lead the expansion of its platform and mobile strategy. McDowall apparently lead product development for Salesforce.com's Chatter Mobile product. Ferrara is a serial entrepreneur who founded popular contact tracking application firm GoldMine, heading it until it was sold in 2000. Ferrara is now applying what he learned at GoldMine to add links to social services to his new platform at Nimble. Nimble's backers include Google Ventures, Mark Cuban, and Jason Calacanis.
