A start-up is a newly established business, often focused on developing a unique product or service. These companies typically aim to solve a specific problem or meet a market need. Start-ups often seek funding from investors to help them grow and scale their operations quickly. Many start-ups operate in the technology sector, but they can be found in various industries, including healthcare, finance, and retail. The goal of a start-up is to achieve rapid growth and eventually become profitable, often leading to an acquisition or an initial public offering (IPO).
