This study investigates sustainability-oriented crowdfunding as a tool for financial institutions to promote sustainable entrepreneurship in Ticino. Using stakeholder insights, expert interviews, focus groups, pilot survey and Business Model Canvas, the research identifies opportunities and challenges in aligning crowdfunding initiatives with sustainability goals. The proposed sustainability-focused crowdfunding platform in Ticino aims to enhance local engagement in sustainability initiatives through a thorough stakeholder analysis. This analysis reveals a diverse range of actors, including institutional organizations, as well as private investors and businesses, each offering unique strengths and varying commitments to sustainability. A bottom-up approach is suggested to counter the perception of sustainability as merely an image-building exercise, focusing on local identity and culture to foster genuine community involvement. However, challenges such as resistance to collaboration due to a silo mentality must be addressed by promoting inclusive and effective communication strategies. Integrating the platform within Cantonal bank’s operations presents both opportunities for increased credibility and challenges in aligning with the bank’s evolving CSR strategy. Ensuring user-friendly access and optimizing project selection based on sustainability criteria are vital for long-term success.
