This practice simulation course provides an introduction to the wide range of legal and business matters that lawyers counseling high-growth businesses typically encounter, from initial formation through growth and exit. We will begin with a discussion of entrepreneurship and the startup company ecosystem, and then cover entity formation; capital-raising sources and mechanisms (including seed funding, SAFEs, convertible debt, venture capital, lines of credit and debt finance); attracting and retaining employees and consultants; protecting intellectual property and other rights; and legal and business governance and conflict-of-interest issues. In the latter part of the course, we will discuss exits of various kinds, including downside scenarios (restructurings and refinancings; distressed company sales and dissolutions) and upside scenarios (mergers and acquisitions, secondary sales and private equity buyouts and public offerings). The course will feature active discussion in a seminar format using recent relevant case law, case studies taken from real-world situations and typical deal documents. It is designed for students contemplating a corporate/transactional practice in a law firm, in-house law department or venture capital or private equity fund.
