One of the UN's 17 goals for sustainable development is to achieve gender equality and empower all women and girls. To coincide with International Women’s Day on March 8, we dedicate an episode of Filling the Sink to female entrepreneurs, particularly those in traditionally male-dominated fields such as technology.

Lea Beliaeva Bander visits the Mobile World Congress at the Fira de Barcelona to meet some of the businesswomen who have created startups in Catalonia. At the 4YFN pavilion, she talks to five female entrepreneurs to gain different perspectives on the challenges faced by women in business in technology.

We meet Maja Završnik, CMO and co-founder of the educational platform SheAI, which helps women to learn how to use artificial intelligence in their businesses and to advance their careers. And host Beth Cohen analyses the statistics surrounding female startups in Catalonia and explores the importance of diversity in the business world.

Our Catalan phrase of the week is ‘buscar una agulla en un paller’ - to look for a needle in a haystack. Which we felt like, when looking for female founders at the 2025 MWC in Barcelona.
