Emotional support is not just externally obtained by entrepreneurs, but also individually created through agency and networking. In this study, we aim to understand the dynamic relation between emotional support and perceived venture goal progress as it evolves over time. We employ a repeated measurement design of up to 10 measurements over twelve months from 86 entrepreneurs participating in a Danish startup program. We find that emotional support enhances perceived venture goal progress, and that venture goal progress boosts emotional social support continuously in a dynamic loop. We also show how brokerage behavior works as a boundary condition for the dynamic support-progress link.
