Reacting Forward (5): Proof of Concept
About this lesson
“No one will need more than 637KB of memory for a personal computer. 640KB ought to be enough for anybody.” – Bill Gates, 1981
(Co-founder and chairman of Microsoft)
From Planning to Committing
If you’ve done this properly — really done it — something has changed.
Your idea is no longer a fantasy.
It has:
- Faces attached to it
- Voices behind it
- Objections wrapped around it
- Numbers supporting it
- Risks exposed within it
You are no longer guessing.
You are informed.
And that’s dangerous.
Because once you truly understand the market…
You lose the right to procrastinate.
The Comfortable Trap
Many people love the business plan phase.
Research is safe.
Talking is safe.
Refining is safe.
It feels productive.
But there is a point — subtle and critical — where planning turns into avoidance.
You can tweak a plan forever.
Add another graph.
Interview two more people.
Rewrite the executive summary again.
At some point, the plan is no longer improving.
You are simply protecting yourself from risk.
The Real Question
Once you know:
- There is a customer
- There is a problem
- There is willingness to pay
- There is a path to reach them
Then the question becomes:
Are you going to commit?
Because planning informs.
But commitment transforms.
The Shift
Up to now, we have focused on:
- Understanding the market
- Understanding customers
- Understanding structure
- Understanding risk
The next step is different.
It is psychological.
It is behavioral.
It is decisive.
It is about moving from:
“I have a well-researched idea.”
To:
“I am building this.”
That shift changes everything.
The Next Lesson
In the next lesson, we step beyond analysis.
We talk about what separates people who understand opportunity…
from those who actually build it.
Because insight without action fades.
And you didn’t come this far to fade.
Let’s move.

Proof of Concept: Where Dreams Meet Revenue
Let me introduce you to George.
George is not impressed by pitch decks.
He is Managing Partner at Red Rocket Ventures — advising growth-stage companies in digital tech. He’s also a venture investor and a serial entrepreneur. Between investment banking, startup leadership, consulting, and running his own B2B e-commerce company, he has seen it all.
More importantly:
He has met over 500 startups.
And they almost all make the same mistake.
George puts it bluntly:
“Most founders come to me right after finishing their product — a website, an app, some cool technology. They’re seeking venture capital to fund sales and marketing. So I ask them:
‘Do you have users? How fast are you growing?’
And they respond:
‘Not yet. That’s why we need the funding.’
At that point, I have to tell them they’re not ready.”
It’s a painful conversation.
And it happens over and over again.
The Fatal Founder Focus
Why does this keep happening?
Because founders fall in love with building.
They obsess over:
- Features
- Code
- Design
- Technology
- Functionality
They keep their heads down, convinced that:
“If we build something great, users will come.”
Sometimes that’s true.
But George’s question cuts through the romance:
By when?
And more importantly:
With what proof?
The Missing Step
Investors don’t fund ideas.
They fund evidence.
Before you ask for capital — from investors, banks, or even friends — you must answer one question clearly:
Where is the proof this works?
That is the purpose of a Proof of Concept.
Prototype vs Proof of Concept (They Are Not the Same)
Many founders confuse these two.
They are not interchangeable.
A Prototype
A prototype is a working model.
It shows:
- How the product looks
- How it functions
- How users navigate it
- What the experience feels like
It is visual.
Interactive.
Tangible.
It answers:
“Can we build this?”
Valuable — but incomplete.
A Proof of Concept (POC)
A Proof of Concept answers a different question:
“Will this work in the real world?”
A POC demonstrates that:
- Customers have tested it
- They see value
- They are willing to engage (or better, pay)
- Distributors can integrate it
- Engineers confirm scalability
- The model holds under pressure
A prototype proves functionality.
A POC proves viability.
Big difference.
The Real Purpose of a POC
A POC is not about perfection.
It is about validation in motion.
It is a controlled, small-scale test designed to answer:
- Does the problem truly exist?
- Does our solution meaningfully address it?
- Will stakeholders participate?
- Can we deliver at small scale?
- Does someone pay?
It reduces risk.
It builds credibility.
It creates leverage.
Without it, you are asking people to believe.
With it, you are showing them evidence.
Why POCs Matter So Much
If you go to investors with:
- A finished product
- No users
- No traction
- No revenue
- No adoption curve
You are asking them to fund an experiment.
If you go with:
- Early users
- Documented feedback
- Repeat engagement
- Early revenue
- Clear unit economics
You are asking them to accelerate momentum.
Investors fund momentum.
The Subtle Founder Trap
Here’s the uncomfortable truth:
Building feels like progress.
Testing feels like exposure.
Many founders avoid POCs because real-world feedback can bruise the ego.
What if customers don’t love it?
What if adoption is slow?
What if pricing is wrong?
Good.
Better to discover that before you run out of money.
The Proof Before the Scale
In the new business world, you do not:
Build → Raise Money → Hope
You:
Test → Prove → Refine → Then Scale
The POC is the bridge between imagination and enterprise.
Without it, you have a product.
With it, you have a business in motion.
Why Investors Need Proof
An idea without evidence has no valuation.
You might see a billion-dollar future.
An investor sees:
- No customers
- No revenue
- No traction
- No validation
And remember — it’s usually not their money. It’s their investors’ money.
They cannot fund belief.
They fund proof.
Until you demonstrate that:
- Customers respond
- The model works
- The economics make sense
You are asking for faith.
Professional capital does not run on faith.
Proof Before Capital
The most effective way to create that evidence is simple:
Run a Proof of Concept.
Start smaller.
Invest your own money.
Your own effort.
Your own reputation.
Build a scaled-down version of the model and test it in the real world.
If customers respond at small scale, investors can envision scale.
If you can’t prove it small, you won’t convince anyone it works big.
My First Proof of Concept
When I incorporated my first company, I believed I had a winning idea.
I targeted an asset generating under $700,000 in revenue. It wasn’t very profitable. I believed I could expand it dramatically and offered $2.1 million — three times annual revenue.
There was one small problem.
I had $30,000 in savings.
Banks declined me.
Venture firms liked the concept — but wanted proof.
The model had never been tried before.
I had never been a CEO.
No one was prepared to leap with me.
So I adjusted.
Instead of chasing the $700,000 asset, I found a smaller one:
- $20,000 in annual revenue
- Losing money
- Available for roughly one times revenue
Unloved.
Undervalued.
Perfect.
I reworked the plan.
When our home sale closed, I used the proceeds to buy that small asset and fund working capital.
That was my Proof of Concept.
Building the Miniature
Within months:
- Revenue increased
- Profit appeared
- Contract manufacturers were aligned
- Distributors were secured
- Marketing began generating new customers
- Outsourced accounting, regulatory, and customer service were installed
In effect, I built a fully operational “hub model” company around a tiny, struggling asset.
Then I went back to the same venture firms.
This time my pitch was different:
“Look at what I did with this worn-out asset.
Imagine what I can do with the bigger one.”
Now they could see it.
Not as theory.
Not as projections.
As evidence.
I got the funding.
Bought the larger asset.
QOL Medical was born.
Without Proof of Concept, it likely would never have existed.
The Expensive Founder Mistake
I see this constantly:
Founders spend every dollar building the product.
Then they have nothing left to test it.
They know they need to:
- Put it in customers’ hands
- Offer pilots
- Run trials
- Collect real data
But they’re out of cash.
They built the engine.
They never fueled the test drive.
Proof of Concept must be built into your business plan — financially and strategically.
You must reserve capital for:
- Testing
- Iterating
- Waiting
- Measuring
A POC is not optional.
It is the bridge between invention and investment.
The Rule
If you cannot risk your own capital, time, and ego on a small-scale proof…
Why should anyone risk theirs at scale?
Prove it small.
Then scale it big.
That’s how real companies are born.

Homework:
🔥 Founder POC Challenge
Prove It. In 30 Days.
You do not need more planning.
You need evidence.
This challenge is designed to force you to create real-world validation — not a prettier slide deck.
You have 30 days.
Phase 1: Define What “Proof” Means (Day 1–3)
Answer these in writing:
- What specific assumption must be true for this business to work?
- Customers will pay $X?
- They will switch from current provider?
- They will use it weekly?
- Distributors will stock it?
- What is the smallest measurable signal that proves this assumption?
Be precise.
Not:
“People like it.”
But:
“10 customers pre-pay $100.”
“3 companies agree to pilot.”
“25% of trial users convert.”
Your POC must produce measurable evidence.
If you cannot define the metric, you cannot prove the concept.
Phase 2: Build the Smallest Test (Day 4–10)
Create the leanest possible version of your idea that allows testing.
Examples:
Digital product
- Landing page + waitlist
- Mock demo + pre-orders
- Manual service behind a “fake automation”
Physical product
- Small batch production
- 3D prototype + pre-sell
- Distributor trial run
Service
- Paid beta clients
- Pilot program
- Limited-time founding offer
Rule:
Do not build the full product.
Build only enough to test willingness to engage or pay.
Speed over perfection.
Phase 3: Get It in Front of Real Humans (Day 11–21)
This is where most founders fail.
You must:
- Speak to at least 25 real potential customers
- Present the offer clearly
- Ask for action (not compliments)
You are not collecting praise.
You are collecting:
- Payments
- Commitments
- Signed pilots
- Pre-orders
- Letters of intent
No “sounds interesting.”
Money, commitment, or rejection.
Rejection is data.
Phase 4: Measure and Adjust (Day 22–26)
Now ask:
- Did the market respond?
- Where did friction occur?
- Was pricing wrong?
- Was messaging unclear?
- Was the problem weaker than expected?
Refine once.
Test again quickly.
POCs are about iteration — not ego.
Phase 5: Present Your Proof (Day 27–30)
Create a one-page “POC Evidence Summary” including:
- The assumption tested
- The model used
- Number of people contacted
- Conversion rate
- Revenue generated (if any)
- Lessons learned
- What changes next
This document is more powerful than any 30-page business plan.
Non-Negotiable Rules
- No hiding behind product development.
- No waiting for perfect branding.
- No additional features.
- No investor outreach during this phase.
You are proving viability, not raising capital.
The Psychological Shift
This challenge does something deeper than validate your idea.
It rewires you.
You stop being:
“I have an idea.”
And become:
“I test ideas.”
That identity shift is powerful.
The Standard
If, after 30 days, you have:
- No real conversations
- No offers made
- No measurable attempt at validation
Then you do not have a startup.
You have a hobby.
Harsh.
Accurate.
Advanced Version (For High Performers)
Shorten the timeline to 14 days.
Set a revenue target.
Force paid validation.
Pressure creates clarity.
At the end of this challenge, one of two things will happen:
- You prove demand and gain unstoppable confidence.
- You discover weaknesses early and pivot intelligently.
Both outcomes are wins.
Now go prove it.
Call to Action: Build Your Soul Dossier
A proof of concept isn’t just something you apply to a product.
You can apply the exact same thinking to your life.
Entrepreneurs often rush straight into building companies without first testing something even more important:
What kind of life are they actually trying to build?
Before you invest your time, energy, and money into a new venture, it’s worth stepping back and running a proof of concept on yourself.
What motivates you?
What kind of work energizes you?
What kind of environment allows you to do your best thinking?
This is where the Soul Dossier comes in.
Your Soul Dossier is a personal document where you begin to record the patterns of who you are at your best — your natural interests, motivations, strengths, and curiosities. Over time it becomes a guide that helps you choose opportunities that are aligned with who you truly are.
Because when your business idea fits the person building it, something powerful happens.
Work feels lighter.
Decisions become clearer.
And persistence becomes natural rather than forced.
So before chasing the next big idea, start collecting the data that matters most.
Start building your Soul Dossier.
It may turn out to be the most valuable proof of concept you ever run. To learn more take a trip here www.souldossier.com
