My name is Leo and I m a new solofounder. I have created this app called Flip Inventory, but oh boy! It has been so hard to get the marketing stuff right (I have a technical background). I realize being solo-founder might not have been the best choice yet. Flip Inventory, for context, helps business owners track materials flowing into their finished goods. This includes stock quantity changes but also incurred expenses. I started Flip to help my brother (e-commerce) stay on top of his backend operations. It has worked wonders for him. Most e-commerce platforms and apps out there are focused on the product sold to consumers and much less on everything else that goes into it (from materials being purchased, to finished product being ready for shipping). This post was not meant to be this long but in short I got only one paying customer after 6 months. And I can t seem to nail down what marketers are calling product market fit . Help and suggestions are sooo welcomed.
