*A YouNoodle Score is a measurement, on a scale of 0 to 100, of a startup's progress as an early-stage company. Typically, a 0-15 company is just getting started, a 30-60 company has experienced some very strong growth (through traffic, funding, or revenue), and a 90-plus company is a strong IPO or acquisition candidate. The score is based on a sophisticated algorithm using information from thousands of online sources: traffic, level of mainstream media coverage, funding, blogosphere activity, and other key factors.
