How would you design a 2-sided marketplace app?

Focus on identifying the two user groups that will interact within the marketplace and clearly define their needs and pain points. Consider the core functionalities that will facilitate interactions between these groups, such as user profiles, listing features, and communication tools. Discuss how you would ensure a seamless onboarding experience for both sides and how you would handle trust and safety measures, like reviews or verification processes. Additionally, think about the monetization strategy and how you would balance the interests of both user groups to ensure a thriving marketplace ecosystem.
