Angel investors are individuals who provide financial support to early-stage startups or entrepreneurs in exchange for equity or convertible debt. They often invest their personal funds and may also offer valuable advice and mentorship to help the business grow. These investors typically seek high-potential companies that can deliver significant returns on their investment. Unlike traditional venture capitalists, angel investors usually invest smaller amounts of money and are more willing to take risks on unproven ideas or businesses. Their support can be crucial for startups looking to launch or expand.
