PROBLEM: I have assumptions about my customer's problem, but I haven't tested them with real people.
To be sure a problem is worth your time and resources, you must speak to real people exoeriencibg the problem
Step 5: Customer Discovery
So far, you’ve been working with hypotheses.
You think you know:
What problem people have
Why they care about it
What they experience
What progress they’re trying to make
But you don’t know it for sure yet. The only way to find out is to talk to the people experiencing the problem.
The Evunn Mindset Shift
From What I Believe → What I Can Learn
Don’t ask customers to confirm your idea. Don’t try to convince them that your solution is valuable.
Instead ask:
“What can I learn from their real experiences?”
Your goal isn’t to hear yes, I’d buy that. Your goal is to discover what is actually true.
To find out if the problem is real from people with the problem, use Book 5. Title: Mom Test

The Big Idea from Mom Test
Good customer conversations don’t ask people to predict what they might do. They uncover what people have actually experienced and done.
Instead of saying would you pay for help getting more clients?
Ask: Tell me about the last time you struggled to get clients.
The first question produces opinions. The second produces evidence.

Your Step 5 Outcome
By the end of this step, you should have:
Conducted conversations with 10 people who actually experience your potential problem
Evidence about whether the problem exists in the way you expected
Real examples of the customer’s experiences
Evidence of what they currently do to deal with it
Evidence of the consequences of the problem
Evidence of what they have already tried
A clearer understanding of which assumptions were supported, challenged or disproved
This is a critical milestone.
You are no longer relying entirely on what you think customers need.
You now have evidence from real people.
But you may discover something uncomfortable:
Not every problem you investigated deserves to become a business.
Some may be painful but rarely acted upon. Some may be important but poorly suited to your expertise.
Some may have stronger evidence than others.
That’s why the next step is about choosing what deserves your attention.
🔒 Ready To Run Your Customer Discovery?
Reading about customer interviews won’t give you the evidence.
You need to plan the conversations, recruit the right people, ask the right questions and capture what you learn.
The EVUNN Customer Discovery Interview Kit helps you do exactly that.
It gives you a structured system for:
Recruiting → Preparing → Interviewing → Recording → Analyzing → Learning
One Payment. For All EVUNN Stage 1 toolkits.
What Should I Learn Next?
You’ve now investigated your potential problems with real people. You discovered more than one problem worth pursuing in step 1.
The question is no longer: What problems exist?
It’s which problem deserves my attention first to build a busibess around?
Step 6: Problem Prioritization
You’ll learn how to evaluate your evidence and choose the problem with the strongest business potential to build a profitable business around
That takes you from:
Assumptions → Evidence → Priorities
