Juicero: $120M in Engineering Without a Single Validated Problem
Type: case-study
Stage: Stage 4: Prototype Proof
Difficulty: advanced
Raised $120M for a Wi-Fi juicing machine. Prototypes were engineering marvels. Bloomberg revealed users could squeeze equal juice by hand. Juicero solved a complex problem users didn't have. Discontinued after 16 months. The canonical example of over-engineering without problem validation.
