Chicago-based Base, a company that develops a cross-platform CRM product, has raised $6.8 million in Series B funding led by Index Ventures with Social+Capital Partnership, OCA Ventures and the I2A fund participating. The startup previously raised $1.1 million in funding. Founded in 2009 by Uzi Shmilovici, Base is a CRM product that is catered towards small businesses. Base wants to let businesses manage their customers and sales everywhere they are, and offers applications for the Android phone, the iPhone, Mac and Windows. The company also plans to release tablet and Windows Phone 7.5 apps soon. You can capture, track and visualize your sales leads; manage contacts with notes, tasks and reminders and more. Shmilovici explains that most CRM products are web-based and don't offer mobility for users. As mobility becomes increasingly popular in the enterprise, Base wants to be the go-to CRM option for companies that need sales operations to be managed on the go. "The cloud was only act one of the enterprise software revolution. The end game is to have your data with you on any device, at any time, anywhere you are. This kind of ubiquity, together with a focus on product design and user experience, is what makes the next generation of CRM”, said Shmilovici. Since the beginning of the year, the company grew its user base by more than 500% and is currently being used by tens of thousands of businesses worldwide.
