The Importance of Team Dynamics

In the pre-investment stage, the dynamics of the team are crucial for success, with nearly half of evaluation criteria focusing on the people involved. Engaging founders in discussions about their learning experiences and areas of uncertainty can provide valuable insights. These conversations help illuminate the experiments being conducted to understand market needs and develop effective solutions. By prioritizing the team’s ability to adapt and overcome challenges, investors can gauge the potential for growth and innovation.
