Signs of a data-analysis revolution are everywhere. Remember "Moneyball?" The sports bestselling book and movie trumpeted number crunching over gut instinct. Data analysis now is reshaping the small-business lending space, too.

With bank loan competition still tight, more startups and small-business owners are turning to alternative lenders, which use technology-driven data analytics (aka fancy enterprise software) to gauge loan applicants. The new crop of lenders are also using nontraditional measures to assess applicants. Those measures can include payroll, Better Business Bureau ratings, Yelp ratings and more.
