Metaweb

Metaweb Technologies, Inc. was a San Francisco–based company that developed Freebase, described as an "open, shared database of the world's knowledge". The company was co-founded by Danny Hillis, Veda Hlubinka-Cook and John Giannandrea in 2005.

Metaweb was acquired by Google in 2010. Google shut down Freebase in 2016, transferring some of the data that met the required notability criteria to Wikidata.
