Working as a developer at a startup and going through the process of launching new services, I naturally became interested in user growth and product improvement. Beyond simply implementing features, I was contemplating how to attract more users to our service and keep them engaged continuously, which led me to take this course. Through the course, I was able to learn extensively from core growth marketing concepts to real-world case studies, understanding the process of defining a product's core value and improving it based on data. It was a great opportunity for developers to learn the mindset that connects marketing and product growth. Thank you for the great course!! :)
