About Brilliance Inside

Brilliance Inside is a project for harmony and peace. We work with inmates and correctional officers in the US prison system to reduce conflict and increase communication and connection.

Brilliance Inside is working to transform prison from being strictly a container of violence to a creator of peace by growing resilient high-performance individuals contributing their purpose and a safer society on their release.

The first TEDx event organized and led by the inmates was held at Donovan Correctional Facility in 2017.

About Mariette

Read about how Mariette is Facilitating Freedom through TEDx

      After the wild success of TEDxDonovanCorrectional held at San Diego’s Donovan state prison, Mariette Fourmeaux du Sartel has transferred her passion for building resilient high-performing teams and authentic human-centered leadership – honed through two decades in corporate and start-ups – into the unlikely environment that is prison.  She founded Brilliance Inside, a nonprofit program to transform prison from being strictly a container of violence to a creator of rehabilitation and peace.

Prior to this, Mariette spent 17 years in business, developing cutting-edge technologies for world-scale problems, such as a cancer-detecting medical device in Paris, d.light’s solar lanterns for the rural poor without electricity in India and a new augmented reality technology at HP, Inc.  She also grew up intertwined in the creation and expansion of her family wine businesses, starting at the ripe age of 6.  Mariette is a true global citizen:  born in France, she’s lived on four continents and has explored some of the most remote corners of our world.  Finally, Mariette holds a double materials engineering and economics degree from Brown University and a Berkeley MBA.
