I find it redeeming that despite having a gift for development - software and hardware - the biggest factors affecting profitability and growth here are things that most MBAs would do in a business quite regularly (outsourcing design/packaging/fulfillment, streamlining costs, doing price elasticity experiments, polling customers and markets for product improvement).
I enjoyed seeing the inverted perspective that product/engineering is straightforward and low risk but things like optimizing fulfillment and operating costs is a new exciting endeavor.
One tip I suggest doing is leveraging google ads to figure out features that customers are willing to pay for before you build them... if they're clicking the ad they are searching for it and interested in buying it. Start a few very low cap campaigns calling out features you are thinking of building into the product, and see which one get's the most impressions and clicks per marketing dollar and focus on that. The added advantage is you know it will be easier to buy advertising for it once the feature is done.
