My name is Maria Nefeli Chatziioannidou and I am a social entrepreneur. I graduated from Bocconi University, Italy with a Bachelor’s Degree in International Economics, Finance and Management. I also hold a Master’s Degree in Social Innovation and Entrepreneurship. In 2020 I started a Bachelor's Degree in Psychology at the University of Sunderland.


In 2013 I co-founded my first social enterprise "Code it Like a Girl" (CLG), aiming to solve the problem of gender inequality in STEM fields. In 2015 CLG was an enterprise with 72 active volunteers and it was supported by the US Embassy, the Angelopoulos and Clinton Foundation, the Greek Ministry of Education, Microsoft and Redbull.

In 2019, I created my second social venture called "Great Women" (Yperoxes Gynaikes), with a mission to educate, empower and motivate whoever identifies as a woman to participate, create and develop projects and ventures that have a positive impact in the communities they live in. Additionally, Great Women provide services to organizations and corporations that want to adjust and invest in Corporate Social Responsibility strategies in their business operations and increase their positive impact to society. Great Women is currently a social enterprise that has built a community of more than 100.000 women.

For my work in Great Women I was recently awarded the Greek International Women's Award 2021 in the Category of Social Responsibility. The introductory speech of the ceremony was given by her Excellency the President of the Hellenic Republic and the award was presented by the vice minister of Labor and Social Affairs.

I collaborate and provide consulting services on social innovation and entrepreneurship to several organizations and start-ups in Greece, like Mindspace, Think Young, Entrepreneurship School, and Ethelon Organization, and I am a mentor in Prince’s Trust International Foundation at the program Be Your Own Boss, in the program WOMENTORS by Active Citizen fund and Lamprakis Foundation and in the "Empowerement Program of Female Refugees" created by IRC Hellas and Women on Top. I have participated in various conferences with proposals for the refugee crisis and I participated in “WOMEN INNOVATORS in SOCIAL ENTERPRISES” (WISE) Program, a program of the European Commission where I was awarded as one of the five Top Women Innovators of the Program. In March 2020 I became a member of Women Mediterranean Fund and in October I became one of the twenty female social entrepreneurs of Women Act Europe through its program Empow Her. I was included in the European list of EuClid Network (EN) of the Top 100 Women in Social Enterprises 2021. EN is a strategic partner of the European Commission and an observer to the United Nations Task Force on Social and Solidarity Economy.

To Philosopheio


"To Philosopheio" is a fresh respond to the existing old-fashion, university cafeterias that exist in Greek Universities. It is a university cafeteria inside the Philosophy Department of the Aristotle University of Thessaloniki with a vision to create a place that respects the university students and staff, by providing a modern environment and a quality break for everyone. Breaking all the stereotypes of the typical Greek university cafeteria, 9 months after its launch, “To Philosopheio” opened its second location.
