There is a moment that almost every solo founder experiences in their first 18 months of business. It goes something like this: you have invested time and money building a website, crafting your offer, creating content, maybe even running some outreach campaigns. And the market is responding with what can only be described as polite indifference.

People say your offer sounds interesting. They ask thoughtful questions on discovery calls. Then they disappear. Or they say "let me think about it." Or they want something slightly different from what you are offering — and you wonder whether you should reshape your entire business around every new piece of feedback.

The root cause is almost always the same: you built your offer based on assumptions about what the market wants, rather than evidence from the market itself. You skipped customer discovery — or, more accurately, nobody told you that customer discovery is not just a startup concept. It is the most important growth activity any solo founder can do.

What Customer Discovery Actually Means for Service-Based Founders

Customer discovery is a systematic process of talking to potential buyers to understand their problems, the language they use to describe those problems, what they have already tried, and what they would pay for a better solution. It was formalized by Steve Blank in The Four Steps to the Epiphany for tech startups, but the underlying logic applies directly to any expertise-based business.

For coaches, consultants, and fractional leaders, customer discovery answers the questions that determine whether your business works or does not work: Is the problem you solve something your target audience actively thinks about and spends money on? Do they describe the problem the way you describe it — or do they use completely different language? What have they already tried, and why did those attempts fail? What would a solution need to look like for them to invest in it?

These are not questions you can answer from behind your laptop. They require real conversations with real potential buyers.

Why Most Solo Founders Skip This Step

The reasons founders give for not doing customer discovery are consistent. "I already know my market — I worked in this industry for 15 years." "I do not want to bother people by asking for free interviews." "I just need to get my marketing right and the clients will come." "Customer discovery is for tech startups building products, not for coaches."

Each of these objections contains a partial truth, which is what makes them so convincing — and so dangerous.

Yes, you know your former industry. But your former industry is not the same as your target market as an external service provider. The problems people will pay an internal leader to solve are not always the same problems they will pay an outside consultant to solve. The buying psychology is different. The budget authority is different. The perceived risk is different.

And yes, customer discovery was originally codified for product startups. But the core principle — that every business assumption is a hypothesis until validated by market evidence — applies to any business model. If anything, it applies more urgently to solo founders because you are making every decision alone, without the team feedback loops that larger organizations have.

The Mom Test: How to Have Conversations That Produce Truth

At Rent-a-Cofounder, we use Rob Fitzpatrick's Mom Test framework as the operational manual for every customer discovery interview we conduct. The core insight is deceptively simple: you cannot ask people whether your business idea is good, because they will lie to be nice. Even your mother would.

The framework has three rules that govern every interview:

Rule 1: Talk about their life, not your idea. The moment you reveal your concept, you contaminate the conversation. Instead of learning what they actually need, you start hearing what they think you want to hear. Keep the focus entirely on their experience, their problems, their behavior.

Rule 2: Ask about specifics in the past, not generics or opinions about the future. "Would you pay for a leadership coach?" is a useless question — anyone can say yes without commitment. "Tell me about the last time you invested in professional development. What was it? What did you spend? What result did you get?" That produces actionable data.

Rule 3: Talk less and listen more. Your job in a customer discovery interview is to understand their world. Not to pitch. Not to educate. Not to demonstrate your expertise. Just to listen and ask follow-up questions.

The most important signal to listen for is commitment — not enthusiasm. "That sounds amazing" means nothing. "I spent €5,000 on executive coaching last year and I am looking for someone new" means everything.

How We Run Customer Discovery Inside the Rent-a-Cofounder Program

One thing that makes the Rent-a-Cofounder program unusual is that we do not just teach customer discovery — our team conducts five professional interviews on behalf of each client in Month 2 of the engagement. We do this because we have seen, repeatedly, that founders interviewing their own potential customers introduce bias even when they are trained not to.

Here is the process:

Step 1: Define the hypothesis. In Month 1, during our intake process, we develop a clear positioning hypothesis that includes your assumed ideal customer profile, the problem you believe you solve, and how you believe you are differentiated. This is explicitly framed as a hypothesis — a testable assumption, not a fact.

Step 2: Design the interview guide. We build a conversation guide that follows Mom Test principles. Questions are structured to explore the prospect's world, not validate our assumptions. We are looking for evidence of real pain, real spending, and real attempts at solutions.

Step 3: Conduct the interviews. Our team runs five structured conversations with people who match the hypothesized ideal customer profile. Each interview is recorded, transcribed, and analyzed for patterns.

Step 4: Analyze for patterns. We look for recurring themes: What problems come up most frequently? How do prospects describe their situation — what exact words do they use? What have they tried and what did not work? Where are the commitment signals?

Step 5: Confirm or challenge the hypothesis. By the end of Month 2, the milestone is Problem-Hypothesis-Confirmation. Either the data supports the positioning hypothesis — and we proceed to build content and outreach around validated positioning — or the data reveals a better direction, and we pivot before investing further in the wrong message.

This step saves founders months of wasted effort. It is the difference between posting content that gets crickets and posting content that generates conversations.

The Real-World Impact of Customer Discovery on Business Growth

The downstream effects of doing customer discovery properly cascade through every part of your business.

Content creation becomes dramatically easier. When you know exactly how your target audience describes their problems — in their own words, not yours — writing LinkedIn posts stops feeling like pulling teeth. You are no longer guessing at what might resonate. You are reflecting their reality back to them, which is the most effective form of content possible.

Outreach conversion rates improve. Cold or warm messages that reference a real, validated pain point get responses. Messages that reference a hypothetical pain point get ignored. The difference is not copywriting skill — it is market knowledge.

Sales conversations accelerate. When prospects arrive at a discovery call and hear you describe their situation with specificity and accuracy, trust forms immediately. They stop evaluating whether you understand their problem and start evaluating whether they want to work with you. That shift alone can cut your average sales cycle in half.

Offer design gets sharper. Customer discovery data tells you not just what problem to solve, but how to package the solution. What scope feels right? What price point matches the perceived value? What entry-level offer reduces perceived risk? Every answer comes from the market, not from your imagination.

Customer Discovery Is Not a One-Time Event

One of the most important things we teach our clients is that customer discovery is not a phase you complete and leave behind. It is an ongoing practice that should be woven into the fabric of how you run your business.

Every client engagement generates discovery data. Every sales call that stalls gives you feedback. Every piece of content that outperforms expectations tells you something about what the market cares about. The founders who grow fastest are the ones who treat every market interaction as an opportunity to learn.

Inside the Rent-a-Cofounder program, we train clients to conduct their own customer discovery interviews and embed the habit so it continues long after the engagement ends. By the time we reach Month 6 and hand over the system, you are not just equipped with a sales funnel and content engine — you are equipped with the skill to continuously refine your positioning based on real market feedback.

How to Start Customer Discovery This Week

If you are not currently running customer discovery interviews, here is how to start with minimal friction:

Identify 10 people who match your assumed ideal client profile. They can be former colleagues, people in your network, or connections you have built on LinkedIn. They should be people who plausibly have the problem you want to solve — not friends or family.

Reach out with a genuine request for insight. Do not pitch. Do not sell. Say something like: "I am building a practice focused on [area]. I am doing research to make sure I am solving the right problems in the right way. Would you be open to a 20-minute conversation about your experience with [problem area]? I am genuinely interested in your perspective, not trying to sell you anything."

In the conversation, follow the three rules. Talk about their life. Ask about past specifics. Listen more than you talk. Take notes on exact language — the words they use to describe their problems are marketing gold.

After five conversations, look for patterns. What came up more than once? What surprised you? What language did they use that you had not thought of? Where did your assumptions match reality, and where did they diverge?

Five conversations will not give you statistical certainty, but they will give you something infinitely more valuable than zero conversations: directional data that makes every subsequent business decision better.

When You Are Ready for a Structured Approach

Customer discovery is powerful even when done informally. But it becomes transformative when it is part of a structured system — when the interviews feed into positioning, the positioning feeds into content, the content feeds into outreach, and the outreach feeds into sales conversations that convert.

That structured system is exactly what the Rent-a-Cofounder program delivers. We are not a marketing agency that needs a brief. We are embedded partners who learn your business, run the discovery, build the content, configure the outreach, and coach your sales conversations. Over six months, we build a client acquisition engine that you own and operate independently.
