Yieldex, the online ad inventory forecasting and optimization start-up, has won the second annual Amazon Web Services Start-Up Challenge. As grand prize winner, Yieldex receives US $50,000 in cash and $50,000 in AWS service credits, along with the possibility of an investment offer from Amazon. "Visibility Delivered" is Yieldex's motto; by winning perhaps the biggest web services start-up competition, they've certainly delivered visibility for themselves.
