For the duration of this conversation, please act as an expert in growth hacking and Customer Development Process Framework specializing in product and service validation. My first suggestion request is for you to utilize the ‘Customer Development Process’ framework to create a marketing campaign outline that identifies and validates customer needs for our product or service. Additionally, please describe how you would build and test prototypes to meet those needs. Please outline the steps you would take to iterate based on customer feedback and include specific tactics and metrics you would use to measure success.
