Our usual advice to hardware founders is to focus on getting a product to market to test the core assumptions on actual target customers, and then iterate. Instead, Juicero spent $120M over two years to build a complex supply chain and perfectly engineered product that is too expensive for their target demographic.
Note: These are not sprints. I despise the word sprints. Sprints and work don’t go together. This isn’t about running all out as fast as you can, it’s about working calmly, at a nice pace, and making smart calls along the way. No brute force here, no catching our collective breath at the end.
