A start-up with a brilliant business idea is aiming to get its operations up and running. From humble beginnings, the company proves the worthiness of its model and products, steadily growing thanks to the generosity of friends, family, and the founders' own financial resources. Over time, its customer base begins to grow, and the business begins to expand its operations and its aims. Before long, the company has risen through the ranks of its competitors to become highly valued, opening the possibilities for future expansion to include new offices, employees, and even an initial public offering (IPO). However, the path for each start-up is somewhat different, as is the timeline for funding.
