Venture financing provides startups and high-growth companies with capital in exchange for equity. It carries high risk but potential for significant returns. There are different types of venture financing including seed funding from founders' savings, angel investors who are wealthy individuals, and venture capital firms who invest larger sums and provide support. Venture capitalists invest professional funds in later-stage companies while angel investors back earlier-stage ventures and offer mentoring. The venture financing process involves researching investors, creating a compelling pitch, and negotiating terms of the investment.
