This chapter examines the role of crowdfunding in social finance, focusing on how it provides social enterprises (SEs) with alternative methods of raising capital. Crowdfunding allows SEs to engage directly with backers motivated by social and financial returns. The chapter covers various crowdfunding models, including donation-based, reward-based, equity-based, and debt-based, while addressing the challenges SEs encounter, such as illiquidity, regulatory barriers, and market saturation. It also discusses emerging trends, like blockchain technology and hybrid crowdfunding models, as potential solutions for improving social finance transparency, liquidity, and flexibility. The chapter discusses the importance of policy support and standardized social impact metrics to ensure the continued growth of crowdfunding as a sustainable tool for financing socially impactful ventures.
