With the F10 FinTech Hackathon in Vienna coming up, we have analysed what successful teams have in common. The findings: gender-diverse teams perform best. The diversity factor is even believed to have greater implications than the intelligence of individual members. The presence of female team members in male-dominated work areas increases objectivity, the group’s performance and overall satisfaction with the tasks. F10 therefore highly encourages the Hackathon participants to form diverse teams.
