An advisory board is crucial for several reasons: 1. Expertise: Entrepreneurs often lack experience in certain areas. An advisory board brings in diverse expertise in fields like marketing, finance, operations, and product development. 2. Networking: Advisors can open doors to new opportunities and connections that can help the business grow. 3. Credibility: Having a well-known advisory board can enhance the credibility of the startup in the eyes of investors, partners, and customers. 4. Strategic Guidance: Advisors provide strategic advice that can help navigate challenges and seize opportunities.
