When a startup first begins, cash flow is non-existent. And it can often fall on the entrepreneur's spouse to help provide for the family while the startup gets on its feet. This can cause a number of challenges, as you can imagine. Recently, I revisited Meg Cadoux Hirshberg's Founders School series, looking to the module "When the Breadwinner Gets Crusty". Meg is an author featured regularly on Inc.com, whose writing focuses on the trials and tribulations a family encounters when one of the members jumps into founding a business.
