Subscription-based businesses are super popular and Danny realized that there was a large gap in the market - he wanted to create a new streaming service that only had food-related content - something like Netflix but with only cooking shows!
Danny found a few smart friends to launch his new startup Foodie-Fi in 2020 and started selling monthly and annual subscriptions, giving their customers unlimited on-demand access to exclusive food videos from around the world!
Danny created Foodie-Fi with a data-driven mindset and wanted to ensure all future investment decisions and new features were decided using data.
This case study focuses on using Foodie-Fi data; subscription-style digital data to answer important business questions that could help the startup an insight into critical business metrics relating to the customer journey, payment transactions, and overall business performance.
