MM started her career in business, as a consultant in New York and Europe and as an associate in the Silicon Valley office of JP Morgan's Private Bank. During that time, she started writing pseudonymously, including several viral essays, copy for a high-end sex toys company, and a Young Adult series under the pen name Sadie Hayes (Social Code & The Next Big Thing; St. Martin's Press, 2012). She finally quit finance to serialize and then publish her debut novel, THE UNDERWRITING (Penguin, 2015), which was published in 20 languages and whose television adaptation she also wrote for Fox.
She is a Tribeca Disrupt Fellow, a French-American Young Leader and a Trustee of the Belarus Free Theatre. She holds a BA in Literature and an MBA from Stanford University, and currently splits her time between London and Asheville, North Carolina, where she was born and raised.
