How Juicero Raised $120M to Build a $400 Machine That Squeezed Juice Bags

Doug Evans envisioned Juicero as "the Keurig for juice": proprietary pre-packaged fruit/vegetable packs that a connected machine would press into fresh juice. The machine was beautifully engineered, with custom-milled aluminum and 4 tons of pressing force.

The problem: nobody asked whether 4 tons of pressing force was necessary to squeeze a bag of pre-chopped fruit.

What went wrong — No First Principles on the core value: First Principles would have asked: "What does making juice fundamentally require?"

• Extracting liquid from fruits and vegetables
• "Do pre-cut, pre-packaged fruits in a bag require 4 tons of force?" → No. You can squeeze them by hand.

The entire $400 machine was unnecessary. This is the textbook case of solution-first thinking — building an impressive technology without verifying the problem requires it.

What they needed — Abstraction Laddering:

• Going up: "Why do people want a juicer?" → "For fresh, healthy juice" → "For convenient nutrition"
• Going down: "How do we provide convenient nutrition?" → Options: juice bars, pre-bottled juice, fruit delivery, a simple manual press, OR a $400 WiFi-connected machine

The $400 machine was the most complex, most expensive answer to a simple need. Every other option was cheaper and simpler.

Inversion: "What would guarantee this product fails?"

• Make it expensive ($400 machine + $5-8/pack subscriptions)
• Make it do something customers can do by hand
• Make it WiFi-connected (the machine refused to work if the WiFi was down or if it detected an "expired" pack)
• Don't validate that the machine is necessary before building it

Juicero did all four.

Juicero became Silicon Valley's most infamous failure:

• Bloomberg's exposé showed reporters squeezing the bags by hand — getting the same juice without the machine
• The video went viral, becoming a symbol of Silicon Valley excess
• Shut down in September 2017, just 16 months after launch
• $120M in funding from Kleiner Perkins, Google Ventures, and others — essentially wasted
• "Juicero" became shorthand for overengineered, unnecessary products

The lesson for VCs: Kleiner Perkins invested $120M without apparently asking: "Can you squeeze the bags by hand?" A single First Principles question would have revealed the fundamental flaw.
