Grok, formerly named Numenta, is a company founded March 24, 2005, by Palm founder Jeff Hawkins with his longtime business partner Donna Dubinsky and Stanford graduate student Dileep George. It is headquartered in Redwood City, California.

The company was officially renamed Grok in 2013,[1] to emphasize its transition from a research-based venture to a commercial product.


In the 2004 book On Intelligence, Hawkins and co-author Sandra Blakeslee explain a theory of the neocortex. This theory is the basis for Numenta's technology, called Hierarchical Temporal Memory (HTM).

Numenta's name comes from the Latin mentis (“pertaining to the mind”) genitive of mēns (“mind”).[2]

The word Grok is a term that was coined by Robert Heinlein in his 1961 novel Stranger in a Strange Land.


Grok is the flagship product and shares its name with the company. Grok ingests data streams and makes useful predictions in real time. Grok's automated modeling and continuous learning capabilities suit it to drive intelligent action from fast data.

Legacy / Research Products[edit]

The Numenta Platform for Intelligent Computing (NuPIC) is a set of tools and a runtime engine, including embedded learning algorithms, that enables self-training and pattern recognition based on the theories of Hierarchical Temporal Memory (HTM).

The Research Release of NuPIC was announced on March 5, 2007.[3]

A version for the Microsoft Windows operating system was announced on August 29, 2007.[4]

The NuPIC Open Source Project[edit]

Numenta announced in June 2013 that it would open-source the core software underlying Grok. This was accompanied by the new website[5] and a mailing list for community members. A number of contributors from around the world have since joined, and topics on the mailing list have included both discussions of the HTM theory as well as details of development of the software.

A series of hackathons, started in Summer 2013, allow community members to meet up and collaborate on particular aspects of NuPIC and its applications.
