Word up Juicers - before you get started launching and shipping, a word of warning:

The moment you opened this email, a few things happened:

  • A founder somewhere ghost-launched a product no one wanted. Again.

  • Our espresso machine groaned and fired up on its own.

  • And Mr. Juice whispered: “Time to save a few start-ups.”

See, most founders build on lies.
Not because they’re shady.
But because they never test the assumptions running the show behind the scenes.

Today, we’re calling BS on your blind spots - before your launch becomes a LinkedIn post-mortem.

Let’s get into it.

📡What’s on this Week

This week’s Juice?

Think Top Gun with a keyboard.


We’re mixing up our start up cocktail like everyone’s favourite fighter jet action star - fast, loud, and a little bit reckless.


Expect rogue missions, AI co-pilots, and a few G-force pivots along the way.

Buckle up. Mr. Juice is taking flight. ✈️🥤

Here’s what’s on the Juice Menu – spicy, signal-dense, and served daily:

😲 Today - Are You Building on a Lie?

Most founders build on lies - unspoken assumptions about the problem and the customer.

But you’re not like most founders.

You’re a member of the Business Juice crew, and you test your assumptions.

🩼 Tuesday - 2 Prompts That Stop You Building the Wrong Thing - and Help You Launch Something People Actually Want

Building fast is easy. Building what people actually want? That’s the game.

This checklist helps you go from “what should I build?” to “hell yes, let’s ship it.”

Build the MVP Define how to get your first 10 users

Wednesday - Don’t Build Yet, Ask these 3 Questions First

Your first customers know more than you do.

Ask the wrong questions? You’ll get false confidence.

Ask these 3 instead - and get the trust you need to build something that sticks.

🫂Thursday - How to Get Your First 10 Customers (Even with Zero Reach)

Your first 10 customers won’t come from ads.

They come from you - DMs, emails, convos, cold outreach.

Here’s how to find, approach, and convert them without cringe or spam.

🤑 Friday - Your First Payment Is a Test - Here’s How to Pass It

You don’t have a business until money changes hands.

The first $1 is more than validation - it’s momentum.

Here’s how to get it quickly, cleanly, and without feeling salesy.

🧪Testing Your Assumptions

🧠 Big Idea:

Everyone lies when giving you feedback.

Everyone especially lies to founders (that’s you).

They want to be nice.

But they do more harm than good by saving you pain that ultimately kills you.

Your start up success hinges on truth, not compliments.

Your job is to get brutally honest about your assumptions, then test them.

Assumptions are healthy - what kills start-ups is not testing them.

You don't need a full launch to learn; you just need sharp questions and fast feedback.

🤑 Why:
When you break down the assumptions you’ll really get to know what’s true - about the user, the problem, and how they’ll find and buy your solution.

This clarity helps you focus your build, sharpen your pitch, and skip months of wasted effort. No more “I thought this would work” moments.

📝Process / Logic:
This isn’t about endless discovery calls. It’s about identifying two assumptions every founder is already making (whether they know it or not):

  1. the problem you're solving, and

  2. how you'll get customers who want it solved.
    You don’t need permission to test those - just awareness and a simple plan.

🎬Action Steps:

Run the two prompts below, save them into a doc and keep testing until you have un-deniable proof that you’re right (or wrong).

Your job isn’t to be right on day one – it’s to get closer to the truth, faster.
