Board dynamics over the startup life cycle

We explore the dynamics of venture capital (VC)-backed startup boards using novel data on director entry, exit, and characteristics. At formation, a typical board is entrepreneur-controlled. Independent directors join the median board after the second financing, when control becomes shared, and hold a tie-breaking vote. Their presence is particularly likely when the potential for VC-entrepreneur conflicts is higher. At later stages, control switches to VCs and independent director characteristics change. These patterns are consistent with independent directors playing both a mediating and advising role over the startup life cycle, and thus representing another potential source of value-add to startup performance.
