All companies face challenges designing a governance system that works best for their particular situation and structure. Even the owners of privately held companies sometimes struggle with issues of separation and control. The challenges can be particularly acute when a company founder has considerable influence over the organization and its culture, and third-party investors have been brought in to share ownership.
