Most businesses begin with someone who is skilled and passionate about their craft.

A great designer opens a design agency. A skilled tradesperson starts a construction company. A marketing expert launches a consultancy. A talented baker opens a café.

Yet, turning expertise into a thriving business is a different challenge.

This is one of the central lessons in Michael E. Gerber’s book, The E-Myth Revisited.

Gerber describes what he calls the “entrepreneurial myth”: the belief that most small businesses are started by entrepreneurs. In reality, many are started by skilled professionals who decide they would rather work for themselves.

It is easy to find yourself in a demanding job rather than in a business that can grow and thrive.

When Everything Depends on the Founder

In the early stages, it is normal for a founder to do almost everything.

You sell the product, answer customer inquiries, manage finances, deliver the service, solve problems, and make every important decision.

Being hands-on is often essential in the early days. As the business grows, though, relying on one person for everything can start to limit progress.

When every decision has to go through the founder:

• Customers wait longer for answers.
• Employees are unsure what they can decide.
• Important tasks are completed inconsistently.
• Growth creates more pressure rather than more freedom.
• The founder has little time to focus on the future.

A busy business is not always a stronger or more manageable one.

A useful question for every founder is:

What would happen to the business if I stepped away for two weeks?

Would the team know what to do, or would progress stall?

Start with One Area of Dependency

There is no need to transform everything at once.

Start by noticing one area of the business that depends most on you.

It might be preparing quotations, responding to enquiries, approving content, managing customer complaints, or onboarding new clients.

Then ask:

1. What currently happens?
2. Where does the process slow down?
3. What information is repeatedly requested?
4. Which decisions could someone else make?
5. What checklist, template, or tool would make the process easier?

Sometimes, a simple checklist or guide is all it takes to begin building a business that is less reliant on one person.

Many founders make the mistake of thinking they have validated their idea when they actually have not.

Friends often describe the idea as brilliant. Family members claim they would purchase it. Potential customers respond with enthusiasm.

Yet, no one makes a purchase.

This problem is so common that Irish entrepreneur Rob Fitzpatrick wrote a book about it called The Mom Test.

The main idea is simple:

• People generally want to be supportive.
• They aim to avoid causing disappointment.

So when you ask whether your idea is good, people often say what they think you want to hear rather than what you really need to know.

Even close family members are likely to say your business idea sounds promising.

That’s why the book is called The Mom Test.

The Problem With Asking for Opinions

• Would you use this?
• Do you like this idea?
• Would you pay for this?
• What is the issue?

The Problem?

These kinds of questions make people guess what they might do in the future. But people are usually not very good at predicting what they’ll actually do.

A customer might genuinely think they will buy your product, but when it comes time to buy, their priorities can change.

This leads to a false sense of confidence. Founders might see positive feedback as proof of product-market fit, even when it isn’t really there.

Here’s a real-world example: Before launching Dropbox, founder Drew Houston faced a big challenge.

Cloud storage was a novel concept, and many people found it difficult to understand.

Instead of building an expensive product right away, the team made a simple demo video that explained the problem and how Dropbox could solve it.

The response was highly positive. Thousands of individuals joined the waiting list.

Instead of just asking for opinions, Dropbox looked at what customers actually did.

Customers took concrete action.

This gave the team real confidence that the problem was real and worth solving.

Here’s the main takeaway:

Actions tell you more than opinions ever will.

What Should You Ask Instead?

According to The Mom Test, effective customer conversations focus on past behavior rather than future intentions.

Instead of asking:

“Would you use this?”

Ask:

“How are you solving this problem today?”

Instead of asking:

“Would you pay for this?”

Ask:

“What have you already spent money on to solve this problem?”

Instead of asking:

“Do you like this idea?”

Ask:

“Tell me about the last time this problem happened”

Good customer interviews are more like investigative journalism than sales pitches. The goal is to find out the facts.

You’re not there to collect compliments.

This results in many startups failing because they build solutions before really understanding the problem. Founders often get attached to their own ideas.

Customers, however, value solutions to their own problems.

These perspectives do not always align.

Successful founders spend time trying to understand:

• What frustrates customers?
• How frequently does the problem occur?
• How expensive is the problem?
• What are people currently doing to solve it?
• What happens if they do nothing?

Three Questions Every Founder Should Ask

1. What are customers doing today to solve this problem?
2. How much time, money, or frustration is the problem causing?
3. Have customers already tried to solve it themselves?

If customers are already spending time, money, or effort to solve a problem, there’s a much better chance that a real market exists.

The Scaling Lesson

A major risk in business is developing a product or service that lacks demand.

The Mom Test makes it clear that positive feedback isn’t the same as real validation.

Validation is demonstrated through customer behavior.

• People joining a waiting list.
• People introducing you to others.
• People investing time.
• People spending money.

Businesses that grow successfully do more than listen to feedback. They pay attention to what customers say and watch what customers actually do.

Your Challenge

Rob Fitzpatrick says founders learn the most when they stop trying to prove their ideas and start focusing on understanding their customers.

The next time you speak to a potential customer:

• Don’t tell them about your solution.
• Don’t ask if they like your idea.
• Don’t ask what they would do in the future.

Instead, ask them about a recent time they experienced the problem you are trying to solve.

Listen carefully for:

• What happened?
• How often does it happen?
• What did they do about it?
• What did it cost them in time, money, or frustration?

At the end of the conversation, ask yourself:

Did I learn something new about the problem, or did I spend the conversation trying to prove my idea was right?

The best customer conversations don’t just confirm what you already think.

They challenge your assumptions.

Most founders believe they need more customers, more funding, more staff, or more marketing.

Yet one of the most influential business books ever written argues that growth is often being held back by something much simpler.

In The Goal, Eliyahu Goldratt introduced a powerful concept that transformed manufacturing and later influenced businesses worldwide:

Every system has a constraint.

And until that constraint is addressed, growth will always be limited.

What Is a Bottleneck?

A bottleneck is the point in a process where work slows down and begins to pile up.

Imagine an hourglass.

No matter how much sand sits at the top, the amount flowing through is limited by the narrowest point in the middle.

Businesses work the same way.

Examples include:

• A founder approving every major decision.
• A sales team generating more opportunities than can be delivered.
• A manufacturing process is waiting on one machine.
• Customer onboarding is taking weeks instead of days.
• Product development struggling to keep pace with customer demand.
• A recruitment process that delays key hires.

Most businesses try to improve everything at once.

Goldratt’s argument was different:

Find the constraint first.

Because improving non-constraints often creates activity, but not meaningful results.

A Billion-Dollar Example

One of the most striking examples of a bottleneck occurred during the global semiconductor shortage.

Car manufacturers had customers waiting, factories ready to operate, employees available to work, and dealerships ready to sell vehicles.

Yet production slowed dramatically because one small component, computer chips, became the constraint.

Despite billions invested in factories, logistics, and sales operations, the entire industry was limited by the availability of a tiny component.

A single bottleneck disrupted global supply chains and cost the automotive industry billions in lost production and revenue.

The lesson is simple:

The strength of a system is determined by its weakest point.

It doesn’t matter how effective the rest of the business is if one critical area is limiting growth.

What This Means for Founders

In early-stage businesses, the constraint is often not where founders expect.

At startup events, investors repeatedly highlight a common issue:

Founders spend months building products, websites, branding, and technology before fully understanding what customers actually need.

In these situations, the bottleneck isn’t marketing.

It isn’t funding.

It isn’t technology.

It’s customer understanding.

Before scaling, businesses must ensure they are solving a real problem for a clearly defined customer.

Three Questions Every Founder Should Ask

1. What is currently slowing growth the most?
2. Where does work consistently get stuck?
3. If I solved one problem this month, which would have the biggest impact on the entire business?

The answers often reveal the true constraint.

The Scaling Lesson

One of Goldratt’s most important insights was that businesses do not scale by improving everything equally.

They scale by identifying and removing the biggest obstacle to progress.

Then they identify the next one.

And the next.

Growth is not usually about working harder.

It is about systematically removing the constraints that prevent progress.

The businesses that scale successfully are rarely the ones doing the most.

They are often the ones focusing on the right thing.

Your Challenge

Goldratt suggested that before trying to improve everything, leaders should first identify the factor limiting the entire system.

Take 15 minutes this week and ask yourself:

• What is the one thing limiting growth right now?
• If that constraint disappeared tomorrow, what impact would it have on the business?
• Are we spending most of our improvement efforts on the constraint or on everything else?

The answers may reveal where your next breakthrough lies.

Because sometimes the fastest path to growth is not adding more.

It’s removing what is holding you back.

Build What Customers Actually Want

One of the biggest mistakes entrepreneurs make is spending months building a product, service, or business idea before speaking to potential customers.

The reality is that most business failures are not caused by poor execution. They happen because businesses build something that customers simply do not need.

This is where the Lean Business approach comes in.

What is Lean Business?

Popularised by Eric Ries in The Lean Startup, the Lean Business approach focuses on reducing risk by testing assumptions early and learning from real customers before investing significant time and money.

Rather than spending months creating a perfect product, successful entrepreneurs start small, learn quickly, and improve based on feedback.

The goal is simple:

Build → Measure → Learn

Why Lean Businesses Grow Faster

Traditional business thinking often follows this path:

• Build the product
• Launch the product
• Hope customers buy

Lean businesses take a different approach:

• Identify a problem
• Test whether people will pay to solve it
• Build a simple version
• Gather feedback
• Improve and repeat

This allows businesses to avoid costly mistakes and focus their resources on opportunities that have genuine market demand.

What Investors Want to See

One of the key themes emerging from recent technology and startup events is that investors are placing greater emphasis on customer validation than ever before.

At London Tech Week and other startup events, investors consistently highlighted the importance of speaking to customers before building solutions.

Many investors are no longer impressed by a polished pitch deck, a detailed business plan, or even a finished product. What they want to see is evidence that real customers have validated the problem and are interested in the solution.

A message heard repeatedly from investors was:

“If you haven’t spoken to at least 100 potential customers, you’re probably not ready to scale.”

Why? Because customer conversations reduce risk.

Investors know that businesses succeed when they solve genuine problems. Speaking directly to customers helps founders understand pain points, validate demand, refine their value proposition, and avoid building products that nobody wants.

Before seeking investment, ask yourself:

• Have I spoken to potential customers?
• Have they confirmed this is a real problem?
• Have they shown genuine interest in a solution?
• Have any agreed to trial, pre-order, or pay for it?

The strongest founders don’t start by building.

They start by listening.

Five Questions Every Founder Should Ask

Before investing heavily in a new idea, ask:

1. What problem am I solving?
2. Who experiences this problem?
3. How are they solving it today?
4. Would they pay for a better solution?
5. What is the simplest way to test this?

If you cannot answer these questions, you may need more customer research before moving forward.

The Power of Customer Conversations

Many founders spend more time building than listening.

Yet some of the most valuable business insights come from speaking directly with customers.

Try conducting 20, 50, or even 100 customer interviews before launching your next product or service. Ask open-ended questions and focus on understanding their challenges rather than pitching your solution.

You may discover that the problem is different from what you originally thought. You may even uncover entirely new opportunities that are more valuable than your original idea.

Every conversation is a chance to learn.

Start Small, Learn Fast

Perfection is often the enemy of progress.

The most successful businesses learn quickly by launching small experiments, gathering feedback, and making improvements over time.

Instead of asking:

“How do I build the perfect product?”

Ask:

“What is the smallest test I can run this week?”

That might be:

• A landing page
• A survey
• A prototype
• A customer interview
• A pilot project
• A pre-order campaign

The objective is not to prove you are right.

The objective is to learn.

Key Takeaway

Businesses rarely fail because they learn too quickly.

They fail because they spend too long building without learning.

The Lean Business approach helps entrepreneurs reduce risk, conserve resources, and create products and services that customers genuinely value.

The faster you learn, the faster you grow.

Before you build, talk to your customers. Before you scale, validate your assumptions. Before you seek investment, gather evidence.

Because the most successful businesses don’t start with a product.

They start with a problem worth solving.
