Our leadership

Sergio Rosas

Founder & Chief Executive Officer

Sergio is passionate about creating access to careers that transform lives, and lead to more values-aligned teams, companies, products and experiences.

His belief in connecting others to game-changing opportunities comes from his lived experience as a low-income and first-generation Latino immigrant turned innovation designer and social entrepreneur.

A double-graduate of Stanford University, Sergio holds a BA in Political Science, with Comparative Studies in Race and Ethnicity, as well as a Master’s degree in Learning Science, Design and Technology.

Sergio sources from his consulting background, and his experience partnering with Fortune 500 companies and workforce development organizations.

Through his work, Sergio has built equity-
centered upskilling programs that tech companies use to connect talent with intersectional identities, to tech careers that impact their worlds.

“We work with clients and talent alike to create memorable moments where we collectively build new knowledge. We see ourselves as an extension of your team and talents’ career journey”

Tina Hossain

Chief Operating Officer

Tina opens pathways of opportunity for others by centering their needs and building products and processes to meet them.

Tina draws upon her experience as a first-generation college student and white-collar professional. Her lived perspective, paired with ten-plus years of legislative, management consulting, and business strategy experience, informs her work as COO, and shapes her understanding of how to help others translate their skills into previously unforeseen opportunities. 

Tina holds a BA in Government and International Affairs from Claremont McKenna College, and an MBA in Management & Strategy and Finance from Northwestern University’s Kellogg School of Management.
