Startups are new businesses that apply innovative solutions. To start a startup, you need an idea, investment, and time. You must understand your target market, develop your product, and build your company culture. Startups often fail due to lack of funding, ineffective management, or better competitors. Successful startups have a strong business model and can position themselves in a growing market. There are various stages of startup funding including bootstrapping, angel investors, venture capital, and IPO.
