Many tech and media businesses have been disrupted by power loss and connectivity issues in the wake of Superstorm Sandy. But several companies, like the social media optimization service SocialFlow, are fortunate to have fully operational offices. In addition to being able to offer uninterrupted service to clients, they’ve been generous with their good fortune by opening their offices to entrepreneurs who need space and resources. The workspace sharing hub PivotDesk  has stepped up to create a dedicated page for entrepreneurs affected by the storm. “Entrepreneurial communities thrive when people give before they get,” reads the site, which lists available office spaces at tech companies throughout New York and New Jersey.
