Early years.
Dubinsky grew up in Benton Harbor, Michigan, where her father, Alfred Dubinsky, worked as a scrap-metal broker. She later attended Yale University where, as a student in Jonathan Edwards College, she majored in history and earned her bachelor's degree in 1977. Dubinsky then worked for the Philadelphia National Bank before obtaining an MBA from Harvard Business School in 1981.
After graduating from Harvard Business School, she went to Apple Computer where she worked as a customer-support liaison. By 1985, she ran part of the company's distribution network. 
In 1986, Bill Campbell recruited her to a senior position in Claris, a software subsidiary of Apple. Dubinsky was responsible for international sales and marketing, and within four years, her group was responsible for 50% of Claris's sales. However, Dubinsky decided to leave in 1991, when Apple did not allow Claris to become an independent company.
Palm Inc. and Handspring.
After a year's sabbatical in Paris to study French, Dubinsky met Jeff Hawkins through the introductions of Bill Campbell and Bruce Dunlevie. Hawkins was looking for a CEO to manage Palm Inc.
In 1995, U.S. Robotics acquired Palm Inc. for US $44 million. The first PalmPilot went on sale in April 1996. After a few months, sales started ramping quickly. In its first 18 months, more than one million PalmPilots had been sold. 3Com acquired U.S. Robotics, with its Palm subsidiary, in 1997.
Dubinsky, Hawkins, and Palm marketing manager Ed Colligan quickly became disillusioned with 3Com's plans for Palm, Inc. and left in June 1998 to found Handspring. Handspring became a leader in the market of smartphones with the Treo. The bursting of the dot-com bubble took its toll and Dubinsky lost her place on the Forbes 400 Richest Americans list in 2001. Furthermore, in 2003, Handspring merged with Palm, Inc. The company, formed through the merger was named palmOne. In 2005, palmOne was renamed to Palm, Inc., returning to its roots, and the independent PalmSource was acquired by Access Corporation of Japan.
Numenta.
In March 2005, Donna Dubinsky, Jeff Hawkins and Dileep George, founded Numenta, Inc. The company is based in Redwood City, California. Their goal is to create machine intelligence by developing theory based on the principles in the neocortex.
Numenta focuses on large-scale brain theory and simulation. Numenta researchers work with experimentalists and published results to derive an understanding of the neocortex. Their main research focus areas are cortical columns, sequence learning and sparse distributed representations. They have written a number of peer-reviewed journal papers and research reports on these topics.
Numenta is a technology provider and does not create go-to-market solutions for specific use cases. The company licenses their technology and application code to developers, organizations and companies who wish to build upon their technology." Numenta has several different types of licenses, including open source licenses, trial licenses and commercial licenses. Developers can use Numenta technology within NuPIC using the AGPL v3 open source license.
