Brett is an award-winning software designer and a veteran Silicon Valley entrepreneur and executive. His love for the natural world and passion for environmental justice was shaped early in his life by Rachel Carlson’s Silent Spring. After a period of early environmental activism, Brett went to Williams College followed by a career in software. His first coding assignment was to help develop Bank of America’s first online banking system. He then joined Symantec Corporation shortly after its founding, where he designed that company’s flagship product.

In the decades that followed he started several companies where he created software programs that became market leaders. As the climate crisis deepened, however, he began to think about how he could use his skills to make a difference. The withdrawal of the U.S. from the Paris Agreement provided the impetus to take action. He sold his company and formed Climate Action Now with the mission of giving everyone the means to take meaningful climate action.
