In 1996, he left IBM to become a consultant and entrepreneur.^[2] In 1999, Brown co-founded SmartArrays, Inc. with James Wheeler, and has held a senior position in the company for many years.^[2] The firm develops specialized analytic software based on columnar databases, with memory-resident vector processing, for uses where customers consider commercial off-the-shelf software to be more expensive, slow, or limited. Note: SmartArrays ceased operations and the corporation was dissolved as of February 2019.

In November 2016, on the occasion of the 50th anniversary of the APL workspace 1 CLEANSPACE, Dr. Brown published and presented the paper "A Personal History of APL" which describes how he became involved with APL and some information on the early days of APL not available elsewhere.

The paper is available in two pieces:

• The body of the paper is the main discussion of his early involvement with APL leading to his creation and development of APL2.
• Supplementary sections including "Vignettes and Anecdotes", "APL Blossom Time" Lyrics and "Empty Array Jokes" among others
