Crowdfunding has emerged as one of the most innovative and rapidly growing methods of digital financing in the modern era. It enables individuals, entrepreneurs, startups, social organizations, and creative professionals to raise funds from a large number of people through online platforms.

It discusses different crowdfunding models including donation-based crowdfunding, reward-based crowdfunding, equity-based crowdfunding, debt-based crowdfunding, and hybrid crowdfunding models.
