Look, I'm Ryan Cole. I want to take you back to a specific moment in my life. It was early 2023. I was sitting at my desk, staring at a spreadsheet, feeling something between frustration and quiet desperation. I had been working on a side project for months. I had poured time, energy, and a decent chunk of money into it. I had built the website. I had set up the social media accounts. I had even recorded a few videos. And after all of that effort, I had made exactly zero dollars. Not "a little bit of money." Not "less than I hoped." Zero. Nothing. The project was dead in the water, and I hadn't even realized it until that moment.

The worst part wasn't the lost time or money. It was the realization that I could have known the project would fail much earlier if I had just thought to test it properly. I had spent months building something that nobody wanted, and the signs were there from the beginning. I just didn't know how to read them. That experience — and the painful lessons it taught me — is why I'm writing this article today. Because I've since learned that this pattern is tragically common. People get excited about a side hustle idea. They invest time, energy, and sometimes significant money into building it out. They launch it with high hopes. And then silence. No customers. No sales. No traction.

It doesn't have to be this way. There are systematic, low-cost, low-risk ways to test a business idea before you commit serious resources to it. Ways to validate that people actually want what you're planning to offer. Ways to gather real evidence instead of relying on gut feelings and wishful thinking. I've spent the last few years studying these methods, applying them to my own projects, and talking to entrepreneurs who are much better at this than I was in 2023. This article is going to walk you through the complete validation framework I now use for every new project. If you apply what I'm about to share, you will save yourself months of wasted effort, thousands of wasted dollars, and the crushing disappointment of building something that nobody wants.

The Hidden Cost of Skipping Validation

Before I explain how to validate an idea, I need to make sure you understand what's at stake. Because the costs of skipping this step are far larger than most people realize. Let's start with the straightforward part: money. When you build a business without validating it first, you spend money on things that may turn out to be completely unnecessary. Domain names and hosting. Logo design and branding. Software subscriptions and tools. Inventory if you're selling physical products. Advertising to drive traffic to an offer that nobody wants. I've talked to people who spent thousands of dollars on a side hustle before they ever made their first sale. Some recovered those costs eventually. Many didn't.

But money isn't even the biggest cost. Time is the one resource you can never recover. Every hour you spend building an unvalidated idea is an hour you could have spent on something that might have actually worked. Think about the weekends you might invest. The evenings after work. All of that life energy poured into something that was destined to fail because the demand was never there in the first place. And then there's the hidden cost nobody talks about: emotional damage. When you pour yourself into a project and it fails, it hurts. It makes you question your judgment. It makes you wonder if you're cut out for this whole entrepreneurship thing. The emotional hangover from a failed project can last far longer than the financial loss. Validation prevents this. When you test an idea early and discover it doesn't have legs, you haven't invested enough to feel devastated.

What Validation Actually Means

Let me define what I mean by validation, because the term gets thrown around loosely and I want us to be precise. Validation is not about asking your friends and family if they think your idea is good. Your mother loves you. She will tell you your idea is brilliant regardless of whether it has any commercial potential. Validation is not about getting likes and positive comments on a social media post. People will happily tell you an idea sounds cool without any intention of ever paying for it. Validation is not even about getting people to say they would buy your product. What people say they'll do and what they actually do are often very different things.

Real validation is about observing behavior. It's about getting people to take actions that demonstrate genuine interest and willingness to pay. A valid idea is one where you have concrete evidence — not assumptions, not compliments, not social media engagement — but evidence that real humans with real money want what you're offering badly enough to exchange their hard-earned cash for it. That's the standard we're aiming for. Evidence of willingness to pay. Everything else is just noise.

The Validation Framework: Five Stages from Idea to Confirmed Demand

I've organized the validation process into five stages. Each stage requires more effort than the previous one, but also provides stronger evidence. You can stop at any stage if the evidence suggests the idea isn't viable. You don't need to complete all five stages for every idea. The goal is to spend the minimum amount of time and resources necessary to make a confident decision about whether to proceed.

Stage 1: The Problem Interview

Every successful product or service solves a problem. Before you think about solutions, before you think about features, before you think about pricing or branding or anything else, you need to verify that the problem you're trying to solve actually exists and actually matters to the people you're trying to serve. This stage involves talking to potential customers — real ones, not your friends and family unless they genuinely fit the profile of your target market. You're not selling anything at this stage. You're not even presenting your solution. You're having conversations to understand their problems, their frustrations, and what they've already tried.

Start by identifying where your target customers already spend time. Online communities are goldmines for this. Facebook groups related to the problem area. Reddit communities. LinkedIn groups. Niche forums. Discord servers. The comments sections of relevant YouTube videos and blog posts. You can reach out to people directly with a simple, honest message: "Hey, I noticed your comment about struggling with X. I'm researching this topic to better understand the challenges people face. Would you be open to a quick 15-minute chat? Not selling anything — just trying to learn." Most people won't respond, and that's fine. Some will. Those conversations are incredibly valuable.

During these conversations, listen more than you talk. Ask them to tell you about their experience with the problem area. How do they currently deal with it? What have they tried? What worked? What didn't? How much time or money does the problem cost them? Toward the end, you can introduce your concept gently: "I've been thinking about creating something that would help with this by doing X. Does that sound like something that would be useful to you?" Pay attention to their reaction. Genuine enthusiasm is different from polite agreement. Conduct at least five to ten of these interviews. You'll start to hear patterns. If nobody seems particularly bothered by the problem you're trying to solve, that's also a signal worth paying attention to.

Stage 2: The Smoke Test

Once you've confirmed through conversations that the problem is real and meaningful, the next step is to test whether people are interested enough in your proposed solution to take action. This is where the smoke test comes in. A smoke test is a small, low-effort experiment designed to gauge genuine interest. You create a simple representation of your product or service — a landing page, a description, a mockup — and you see if anyone responds. The name comes from the idea that you're looking for smoke before you invest in building the fire.

The most common smoke test is a landing page that describes your offering and includes a call to action. That call to action could be a "Buy Now" button that leads to a page explaining the product isn't available yet but offering a waitlist. It could be an email signup form. It could be a request for a deposit or pre-order. Another approach is a "concierge test" — instead of building the full product or service, you manually deliver the value to a small number of customers. If you're thinking of creating an online course, you coach a few people through the material live. If you're considering a software tool, you perform the service manually behind the scenes while making it look automated to the customer.

You need to drive targeted traffic to whatever you've built. Leverage the communities and platforms where you've already been doing your problem interviews. Post about what you're working on if the rules allow it. Paid advertising is another option — with $50 to $100 on Facebook, Instagram, or Google Ads, you can drive enough targeted traffic to get statistically meaningful data. Set clear criteria before you run the test. For a landing page with an email signup, a conversion rate above 5% is generally considered strong. For a pre-order or deposit request, even a handful of conversions can be meaningful because putting down money represents much stronger intent.

Stage 3: The Minimum Viable Offer

If your smoke test shows promising signals, it's time to create something real — but still minimal. This is what I call the Minimum Viable Offer, or MVO. It's the smallest, simplest version of your product or service that someone will actually pay for. This is different from a smoke test because you're actually delivering value and collecting payment. The goal isn't just to measure interest anymore. It's to prove that people will exchange money for what you're offering, and that they'll be satisfied enough to not ask for refunds or leave negative feedback.

Think about what's absolutely essential and strip away everything else. If you're creating a course, your MVO might be a single live workshop, not a complete curriculum. If you're offering a service, it might be a single defined package with a clear scope. If you're selling a physical product, it might be a small batch produced manually rather than a manufactured run. Don't give your MVO away for free. Free users behave differently than paying customers. Charge something — you can offer an early-adopter discount in exchange for feedback, but the transaction itself is part of the validation. Your first paying customers are a goldmine of information. Talk to them. Ask what they expected versus what they received. Ask what they'd change. Ask what almost stopped them from buying. These conversations will teach you more about your business than any amount of internal brainstorming ever could.

Stage 4: The Retention and Referral Test

Getting a first sale is validation. Getting a second sale from the same customer is stronger validation. Having a customer refer someone else to you is the strongest validation of all. This stage is about measuring whether your early customers stick around and whether they bring others with them. Retention looks different depending on your business model. For a service business, it means clients who book you again. For a product business, it means customers who come back to purchase additional items. For a subscription business, it means subscribers who don't cancel. High retention tells you that the value you're providing matches or exceeds what customers expected when they purchased.

Referrals are the ultimate signal of product-market fit because they represent a customer putting their own reputation on the line to recommend you to someone they know. You can measure referral potential simply by asking your early customers whether they've told anyone about your product or service. If your early customers are actively recommending you without being asked or rewarded, that's a very strong signal. If they're not, it's worth investigating why — but it doesn't necessarily mean the business is doomed. Some products are simply less referral-prone than others.

Stage 5: The Scaling Signal Check

The final stage of validation isn't about whether the business can work at all — by this point, you've already proven that. It's about whether the business can grow to the size you want it to reach. At this stage, you should have enough data to understand the economics of a single sale. How much does it cost you to acquire a customer? How much revenue does that customer generate over their lifetime with you? If the lifetime value significantly exceeds the acquisition cost, you have a business that can scale profitably.

Is the market you're serving large enough to support your goals? If your ambition is a modest side income, almost any market will do. If you're hoping to build something larger, look at the size of relevant online communities, the search volume for related terms, and the revenue of competitors in the space. Competition is not inherently bad — it validates that there's demand. But you need a clear answer to the question: why would someone choose you over the alternatives?

What to Do When Validation Fails

Most ideas will not pass every stage of validation. That's normal. That's expected. The whole point of this process is to filter out the ideas that aren't worth pursuing so you can focus your energy on the ones that are. But when an idea fails validation, you have options beyond just abandoning it.

Sometimes the core insight behind an idea is sound, but the specific implementation is wrong. In these cases, a pivot — changing one element of the idea while preserving the rest — can transform a failing validation into a passing one. Some ideas fail because they're too broad. Narrowing the focus to a specific niche within the broader market can make all the difference. Instead of serving "freelancers," serve "freelance graphic designers who work with e-commerce brands." Not every idea's time is now. Shelving an idea — putting it aside with the recognition that it might be worth revisiting later — is a perfectly valid outcome. And some ideas simply aren't good ideas. When this is the case, the best thing you can do is kill the idea cleanly and move on. Every dead idea is a bullet dodged.

Tools and Techniques That Make Validation Easier

Over the years, I've found a handful of tools and approaches that streamline the validation process. You can build a simple, effective landing page in an afternoon using tools like Carrd, ConvertKit's landing page builder, or even a simple Google Doc shared publicly with a payment link. You don't need a full website. You don't need branding. You need a clear description of the offer, an explanation of who it's for and why it's valuable, and a call to action. That's it.

Cold outreach gets a bad reputation because most of it is terrible. But thoughtful, personalized messages to people who have expressed interest in the problem you're solving are not spam. I've validated multiple ideas simply by messaging people who commented on relevant posts and asking if they'd be open to chatting about their experience. If you're building something that requires more resources to deliver, pre-selling can validate demand while also funding the initial production. Platforms like Kickstarter and Indiegogo are built for this, but you can also pre-sell directly through your own landing page. A waiting list is a lower-commitment alternative that measures interest without requiring payment upfront — useful data, especially about the size of the interested audience.

The Mindset That Makes Validation Work

I want to close this article by talking about mindset, because the biggest obstacle to effective validation isn't lack of knowledge about the techniques. It's the psychological resistance that makes us not want to test our ideas in the first place. Your idea is not your identity. When an idea fails validation, it doesn't mean you failed. It means you successfully identified an idea that wasn't worth pursuing before it could do real damage to your time and finances. That's a win. Train yourself to see it that way.

The validation process only works if you're genuinely open to discovering that your idea is flawed. If you go into it looking only for confirmation of what you already believe, you'll find it — and you'll be misleading yourself. Real validation requires intellectual honesty. The goal isn't just to get to "yes" so you can move forward. It's to learn. Even when an idea passes validation, the process teaches you things about your customers, your market, and your offering that make you better prepared to execute. Validation should happen fast — weeks, not months. Speed is a competitive advantage because it lets you test more ideas in the same amount of time.

My Personal Validation Checklist

I want to leave you with something practical. This is the checklist I now run through before I commit significant resources to any new project. First, can I articulate the specific problem this solves in one sentence that a stranger would understand? Second, have I talked to at least five people who experience this problem and confirmed that it's genuinely painful for them? Third, have those people described their current attempts to solve the problem — what are they paying for now and what's frustrating about it? Fourth, have I tested the offer in some way and observed actual behavior, not just collected opinions? Fifth, did that test generate evidence of willingness to pay? Sixth, based on what I've learned, can I acquire customers at a cost that makes the economics work? Seventh, am I the right person to build this — do I have the skills, resources, and genuine interest to see it through? If I can answer yes to all seven, I proceed with confidence. If I can't, I know I have more work to do before I'm ready to commit.

Final Thoughts

I think back to that version of me in early 2023 — sitting at my desk, staring at a spreadsheet, realizing I had wasted months on something nobody wanted. I wish I could go back and hand him this article. But I can't go back. What I can do is share what I've learned so that maybe you don't have to learn it the hard way. Validation isn't complicated. It's not expensive. It doesn't require special skills or connections. What it requires is discipline. The discipline to test before you build. The discipline to listen to evidence even when it contradicts what you want to believe. The discipline to kill ideas that don't pass the test and move on to the ones that do.

If you take nothing else from this article, take this: the most expensive words in entrepreneurship are "I think this is a good idea." Replace them with "the evidence suggests this is worth pursuing." That shift will change everything. Now I want to hear from you. Have you ever built something without validating it first? How did that turn out? Or have you used validation techniques that worked well for you? Drop your experiences in the comments. I read every one, and these conversations are where some of the best insights come from. As always, I'm Ryan Cole. Thanks for making it to the end of this long one. I'll see you in the next article.

FAQ ⬇️

What does it really mean to validate a side hustle idea?

Real validation means gathering concrete evidence of willingness to pay, not just collecting opinions. It's not about asking friends if your idea sounds good or counting social media likes. True validation involves observing actual customer behavior — people opening their wallets, submitting pre-orders, or signing up for paid concierge services. The goal is to prove demand exists before investing significant time and money.

How do I conduct effective problem interviews for validation?

Find potential customers in online communities like Facebook groups, Reddit, and niche forums where they already discuss their problems. Send a simple, honest message stating you're researching the topic and would appreciate a 15-minute chat with no sales pitch. During the interview, listen more than you talk. Ask about their current attempts to solve the problem, what's frustrating about existing solutions, and how much time or money the problem costs them. Conduct at least five to ten interviews to identify patterns.

What is a smoke test and how do I run one?

A smoke test is a low-effort experiment to gauge genuine interest before building your full product. You create a simple landing page describing your offering with a call to action like a waitlist signup or pre-order button. Drive targeted traffic through online communities or a small ad budget of $50 to $100. A conversion rate above 5% for email signups is strong, while even a handful of pre-orders represents meaningful evidence since putting money down signals real intent.

What is a Minimum Viable Offer (MVO)?

An MVO is the smallest, simplest version of your product or service that someone will actually pay for. Unlike a smoke test, you're actually delivering value and collecting payment. For a course, it might be a single live workshop instead of a full curriculum. For a service, it's one defined package. The key is charging real money — free users behave differently than paying customers, and the transaction itself provides the clearest validation signal possible.

What are the hidden costs of skipping validation?

Beyond wasted money on domains, tools, and inventory, the bigger costs are unrecoverable time and emotional damage. Months spent building something nobody wants represents lost opportunity to work on viable ideas. The emotional hangover — questioning your judgment, doubting your ability, and hesitating to pursue future opportunities — can last far longer than the financial loss. Validation prevents this by filtering out bad ideas before you're deeply invested.

What should I do if my idea fails validation?

You have four productive options. You can pivot — changing one element of the idea while preserving the core insight. You can narrow the scope to a more specific niche within the broader market. You can shelve the idea for later if market conditions aren't right yet, documenting what you learned. Or you can kill the idea and move on, recognizing that every dead idea is a bullet dodged that could have consumed months or years of your life.

How fast should the validation process take?

Validation should happen in weeks, not months. The goal is gathering enough evidence to make a confident decision, not eliminating all uncertainty. You'll never have perfect information. Move quickly through the stages — problem interviews, smoke tests, and minimum viable offers — and be willing to make judgment calls based on imperfect data. Speed lets you test more ideas in the same timeframe, increasing your odds of finding one that works.
