Duda Vieira (Maria Eduarda Vieira) is a Brazilian entrepreneur from Goiania who originally trained and worked as a lawyer, graduating from PUC-GO in 2018. After sharing her own study routine on social media and seeing a strong response, she began selling organizational resources, which sparked her move into digital marketing.

In 2021 she left her law career to focus fully on content strategy and personal branding, and has since become one of Brazil's leading voices on Instagram growth and positioning, with a large personal following. She now leads Comunidade CEO Digital, a community of tens of thousands of women entrepreneurs across Brazil built around content, positioning, and community-driven sales.
