Following a few case studies I posted earlier this year (Kelkoo, Skype, mysql), here is a more generic analysis about the process of equity splitting. The document is a pdf file I have used a number of times with students, entrepreneurs and I think it is helpful even if not new. At the end, there are also cap tables of other famous and less famous start-ups.
From the inception where a few founders share the initial equity between them to the exit (IPO or M&A) through a possible number of financing events, shares of a start-ups will be shared, distributed among founders, employees and investors. It is one of the most important decisions in a company’s life and should be handled with care.
