Prior to joining FirstMark, Beth was a Managing Director & Partner at BCG, where she led the global venture and business building team, formerly BCG Digital Ventures and now known as BCG X. In that role, she oversaw a team of almost one thousand product managers, engineers, data scientists, designers, growth marketers, operators and more in service of the creation and launch of new businesses across industries—from a GenAI skincare platform for L’Oréal, to fintech tools for first-time homebuyers, to new ventures with Ontario Teachers’ Pension Plan, Equinox, and Allergan. She also served as Global Chair of DEI for BCG X and sat on BCG’s Audit & Risk Board Committee.

Earlier in her career, Beth served as COO and CMO at Kickstarter, where she set and implemented company-wide strategy and supported the development of new products and services for creators. She was CEO of Interbrand in New York and San Francisco, and spent nearly a decade at IDEO, where she helped build and lead new practices and studios. Her early experience spans roles at Trilogy Software, Ford, and Nike.

Beth holds an MBA from Stanford University and BAs in Communication, History, and Spanish from the University of Pennsylvania.
