Wavii
Wavii was a Seattle startup founded by Adrian Aoun in 2008, and was subsequently acquired by Google, Inc. in April 2013. Wavii developed an iPhone app that allowed users to follow topics (e.g., a company, celebrity, politician, athlete, city, etc.) and receive short updates about them in their feed. This app was based on data produced by Wavii's proprietary technology, which used natural-language-processing and machine-learning approaches to convert content on the web (e.g., news articles and blogs) into structured summaries of the stories they contained.
Wavii's team was primarily former Last.fm, Microsoft, and Amazon engineers.
