Part 3 of 3: Build Something Series
The Practical Playbook: From Idea to Traction
You've got an idea. Maybe it came from the disruption of a layoff. Maybe it's been sitting in the back of your mind for years. Maybe Part 2 of this series convinced you that building is actually possible now.
Ideas are the easy part. Execution is everything.
This is Part 3 of our series on building something - the practical playbook for going from idea to actual traction. Not theory. Not inspiration. The actual work of figuring out if your idea can become a business.
I've been doing this for 25 years across six startups. I've mentored hundreds of entrepreneurs through SBDC and SCORE. I've seen what works and what doesn't. What I'm about to share isn't from business school - it's from building.
First, A Reality Check
Before we get into the playbook, let me be honest about what "starting something" actually involves.
Most new ventures fail. Not because the founders are stupid or lazy - because building a business is genuinely hard. The market might not want what you're building. The timing might be wrong. The competition might be too strong. You might run out of runway. Any number of things can go wrong.
This isn't meant to discourage you. It's meant to ensure you go in with realistic expectations.
The good news: failure is usually recoverable. You learn things. You develop skills. You make connections. Even failed ventures often lead somewhere valuable.
The bad news: success typically takes longer and costs more than you expect. If your plan only works under best-case assumptions, it's not a good plan.
With that reality check done, let's get practical.
Product-Market Fit: The Only Thing That Matters
Everything in startups flows from one question: have you built something people actually want?
This sounds obvious. It's not. Most failed startups die because they build something nobody wants, or something that isn't different enough from what already exists, or something that solves a problem that isn't painful enough to pay for.
Product-market fit means you've found a significant group of people who want what you're building enough to pay for it. Not "think it's cool." Not "might use it someday." Actively want it and will exchange money for it.
Here's what product-market fit looks like:
- Customers find you (not just you finding them)
- They tell other people about it
- Usage goes up without you pushing constantly
- Customers get upset when it breaks
- Revenue grows without heroic effort
Here's what the absence of product-market fit looks like:
- Every customer requires convincing
- People try it and don't come back
- The only growth is from your own marketing push
- Nobody cares enough to complain
- Revenue is flat or declining
Most early-stage startups are pre-product-market-fit. That's normal. The work is finding it.
How to Validate an Idea
Before you build anything substantial, you want some evidence that the idea is worth pursuing. This is validation.
Talk to people who have the problem.
Not friends who will be nice to you. People who actually experience the problem you want to solve. Ask them:
- How do they currently deal with this problem?
- What have they tried? What worked and didn't?
- How much time/money/frustration does this problem cost them?
- Would they pay for a solution? How much?
Listen for enthusiasm, not politeness. "That's interesting" means no. "When can I use it?" means maybe.
Look for existing solutions.
If nobody is solving this problem, ask why. Maybe nobody has thought of it (rare). Maybe people tried and failed (learn why). Maybe the problem isn't painful enough to pay for (common).
If people are solving it, that's actually good news - it means there's a market. Your question becomes: why would your solution win?
Find your unfair advantage.
What do you bring that others don't? Domain expertise? Existing relationships? A technical insight? Willingness to serve a segment others ignore?
If your only advantage is "we'll work harder," that's not enough. Hard work is table stakes.
Build the smallest possible version.
Not a complete product. The smallest thing that tests your core hypothesis. A landing page that gauges interest. A manual version of the service. A prototype that looks rough but demonstrates the concept.
The goal isn't to build the business yet. It's to learn whether the business should be built.
The Minimum Viable Product (MVP)
Once you have some validation, you build an MVP - the minimum viable product.
"Minimum" is the hard part. People almost always build too much before getting it in front of users.
Your MVP should:
- Solve the core problem (not all problems)
- Work well enough to actually test with real users
- Be built fast enough that you can learn and iterate
Your MVP should NOT:
- Have every feature you eventually want
- Be polished or beautiful
- Address every edge case
- Try to please everyone
The purpose of an MVP isn't to impress people. It's to learn whether your core concept works.
The Tension Nobody Talks About with MVPs: Viable vs. Valuable
Here's something that standard MVP advice gets wrong, or at least incomplete: there's a real tension between "viable" and "valuable."
Viable should really mean valuable. And sometimes you can cut a feature set down so far that it's not compelling enough to gain any traction - giving you a false negative. You conclude the idea is bad when actually the execution was just too minimal to demonstrate the value.
MVP should also stand for Minimum Valuable Product.
The question isn't just "what's the least I can build?" It's "what's the least I can build that meaningfully solves the problem?"
Those are different questions. And the second one is harder.
The false negative trap.
Imagine you're building a project management tool. You strip it down to just task lists - no assignments, no due dates, no collaboration. That's minimal. Is it viable? Maybe for personal to-do lists. But if you're trying to solve team coordination problems, you've cut so deep that you're not actually solving the problem anymore.
You launch. Nobody uses it. You conclude: "People don't want another project management tool."
But that's the wrong conclusion. People didn't want that project management tool because it didn't actually help them manage projects with their team. You didn't test your idea - you tested a stripped-down version that couldn't demonstrate the value.
Switching costs and crowded markets.
This gets even more important if you're entering a space where alternatives exist. People already have solutions - even if those solutions are imperfect. To get them to switch, you need to overwhelm them with value that exceeds the switching cost.
A marginally better solution won't do it. People won't switch from their current tool to yours unless yours is meaningfully better in ways they care about. "Slightly improved" doesn't clear the hurdle.
How this played out with ReApply.
Let me be specific about this tension in my own experience.
ReApply started as a set of Python scripts. That was my MVP - but I was the only user. It validated that AI could analyze fit and gaps in useful ways. Concept validated.
But when I built it as a platform for others, I faced the minimum vs. valuable tension directly.
I could have built an MVP that was just gap analysis. Upload your resume and a job posting, get a report on where you fit and where you don't. That's valuable information. That's interesting.
But then what do people actually do with it? They know their gaps... now what? I'd built something interesting but not actually useful enough to change behavior.
So the MVP had to include resumes. Gap analysis, custom resumes, and cover letters. That's the minimum that's actually valuable for the problem I'm solving.
How to find the right minimum.
Some questions to ask:
- Does this solve the problem completely enough that someone would actually change their behavior? Not "is this interesting" but "would someone actually use this instead of what they're doing now?"
- What's the minimum feature set where the "aha moment" is possible? What does someone need to experience to understand why this is valuable?
- If I cut this feature, does the remaining product still deliver meaningful value? Keep cutting until the answer is "no" - then add that feature back.
- What are people comparing me to? If alternatives exist, what's the minimum to demonstrate superiority?
Build the minimum valuable product. Then iterate from there.
Finding Your First Customers
This is where most people get stuck. You've built something - now who's going to use it?
Start with people you know.
Not to sell to them necessarily (though maybe). To learn from them. Do they have this problem? Do they know people who do? Can they introduce you?
Your first customers almost always come through some connection - even if it's a weak one. Cold outreach works, but warm intros work better.
Go where the problem exists.
Where do people with this problem gather? Online communities? Industry events? Specific companies? Go there. Not to spam - to understand and participate. Become useful before you become salesy.
Content marketing isn't just for big companies.
Writing about the problem you solve attracts people who have that problem. This series you're reading? It's content marketing for ReApply. I'm not hiding that. But I'm also providing genuine value - these posts are useful even if you never use my products.
What can you write or create that would be useful to people with the problem you solve?
Your first users should be accessible.
Don't start by trying to sell to Fortune 500 companies. Start with people you can actually reach, who can make decisions quickly, who will give you feedback. Small businesses. Individual practitioners. Early adopters who like trying new things.
You can go upmarket later. Get traction first.
Go-to-Market Strategy: How People Find You
"Build it and they will come" is not a strategy. You need to think clearly about how customers discover you.
Understand the customer journey.
How does someone with this problem currently look for solutions? Do they Google? Ask colleagues? Browse marketplaces? Read reviews? Go to conferences?
Your go-to-market should meet people where they already are.
Choose channels you can actually execute.
There are dozens of possible marketing channels. You can't do them all. Pick 2-3 that:
- Make sense for your customer (where they actually are)
- You can actually do well (your skills and resources)
- Have reasonable economics (cost to acquire < lifetime value)
For ReApply, my primary channels are:
- Content marketing (like this blog)
- Generous free tiers (let the product speak)
- Word of mouth (from satisfied users)
I'm not doing paid advertising, enterprise sales, or influencer marketing. Not because those don't work - because they don't fit my situation as a solo founder.
Generous free tiers can be your best marketing.
This is my strong belief based on experience: in many products, the best marketing is letting people use it.
ReApply gives three free applications. FitCheck gives 10 free fit checks per month. Why? Because once people experience what the product actually does, some percentage of them become paying customers.
Free tiers have costs - server resources, support load, freeloaders. But if your product genuinely provides value, letting people experience that value is often your most efficient marketing.
Thinking About Financials
Most early-stage founders either obsess about financials too early or ignore them too long. The right approach is in between.
You don't need a complex financial model on day one.
You need answers to a few basic questions:
- How much does it cost to acquire a customer?
- How much revenue does a customer generate?
- Is there margin between those numbers?
- How much runway do you have?
That's it. Everything else is refinement.
Unit economics is the game.
Unit economics means: what happens at the level of one customer? This applies whether you're building software, running a massage therapy practice, or starting a landscaping business.
You need to understand:
- What does it actually cost to serve one customer? Not rough estimates - actual costs.
- What does it cost to acquire a new customer? Marketing spend, time invested in sales, referral incentives - all of it.
- What revenue does each customer generate? One-time purchase? Recurring? Multiple transactions over time?
- Is there margin between those numbers? If it costs you $50 to acquire and serve a customer who pays you $40, you lose money on every customer.
Stress test your assumptions.
Your financial model works with your current assumptions. But what if you're wrong?
- If your conversion rate is half what you projected, does the business still work?
- If your costs are 50% higher than expected, do you have margin to absorb that?
- If it takes twice as long to acquire customers, do you have the runway?
Build your model, then break it. Find the assumptions that would kill you if they're wrong. Those are the ones to monitor most closely.
Cash flow matters more than profit.
You can be "profitable" on paper and run out of cash. What matters is: do you have enough money to keep operating until the business sustains itself?
Track your cash. Know exactly when you run out at current burn rate. Plan accordingly.
The Paid Advertising Trap
This deserves its own discussion because it's where a lot of early-stage businesses waste money.
Without recurring revenue, paid advertising rarely makes sense.
If you're selling a one-time $20 product, how much can you afford to spend acquiring each customer? If paid advertising costs $15-25 per conversion (common in competitive markets), you're either breaking even or losing money on every sale.
The math changes with recurring revenue. If that customer pays $20/month for an average of 12 months, you can afford to spend much more to acquire them.
The alternative: earned attention.
Content marketing. Word of mouth. Building in public. Community engagement. These are slower but often more sustainable for bootstrapped businesses.
You're trading money for time. If you have more time than money (common when bootstrapping), that's often the right trade.
The Funding Reality Check
This might be the most important section in this entire series. Because I've watched countless aspiring entrepreneurs make the same fundamental mistake: assuming that getting funding is a given.
That's not true. And even when it is available, it often comes with massive downsides.
The venture capital math.
Let's be clear about what venture capital is looking for: unicorns. Billion-dollar outcomes. That's not an exaggeration - it's the explicit model.
VCs make placed bets across a portfolio. Most of their investments will fail completely. They need a small number of massive winners to make the whole model work. That means they're only interested in ideas that have billion-dollar potential.
If you're building a service that compares car wash prices in your local community - no investor will ever be interested. Not because it's a bad business. It might be a great business. But it's not a billion-dollar business.
Other funding options aren't much better.
What about bank loans? Banks need collateral. If you don't have assets to secure the loan, you're not getting one. And if you do get one, you're personally guaranteeing it.
SBA loans? Better terms, but still require collateral, personal guarantees, and a credible business plan.
Home equity loan? Please don't bet your house on an unproven business idea.
Even if you get funding, it's complicated.
You have investors to answer to. Board meetings. Reporting requirements. People with opinions about how to run your company.
You have pressure to hit milestones, raise the next round, show the growth metrics that justify the valuation.
You've traded creative autonomy for capital. Sometimes that's the right trade. Often it isn't.
The Case for Bootstrapping
So what's the alternative? Build it yourself. Start small on purpose. Bootstrap.
Yes, it's slower. Yes, it's harder. Yes, it's lonely. There's a lot of silence, a lot of small failures, a lot of figuring things out alone.
But here's what you get in return:
Whatever you build is yours.
No investors to answer to. No board telling you what to do. Your company, your decisions, your equity.
You learn hard lessons fast.
When you're spending your own money, you can't afford to be sloppy. Every decision matters.
You build what the market actually wants.
Without funding, you can't build speculatively for years. You have to find customers and revenue quickly.
You stay focused.
When you're bootstrapping, you can't afford to chase every opportunity. That focus is a competitive advantage.
The bar is lower than it used to be.
This connects directly to what we discussed in Part 2: bootstrapping is more possible than ever.
AI tools can fractionally replace what used to require full-time employees. Cloud infrastructure means you don't need to buy servers. The cost of starting something has dropped dramatically.
A decade ago, building what I've built with ReApply would have required a team and significant capital. Today, it's a company of one with AI tools and cloud services.
What bootstrapping looks like in practice:
- Start small on purpose. Don't try to build the full vision on day one.
- Get users. Not millions - enough to learn from.
- Get customers. Even a few paying customers validates that you're building something people value.
- Get traction. Organic growth, even if it's slow.
- Achieve positive cash flow. Revenue exceeds costs.
- Build organically. Reinvest profits into growth.
Don't skip steps. Don't growth-hack your way into something you don't understand. Business has to be earned. Profit has to be earned.
The Mindset That Kills Ideas
Ideas die from execution failure more than from being bad ideas. Here are the mindset traps I see kill ventures:
"I need to get it perfect first."
Perfectionism is procrastination. Ship something imperfect. Learn. Improve.
"Someone might steal my idea."
Ideas aren't worth stealing. Execution is worth stealing, and you can't steal that.
"I need funding to start."
Most ideas can be validated with minimal capital. Don't use "I need funding" as an excuse to not start.
"I need a co-founder/team/developers."
What can you do alone? Start there. You'll learn what you actually need as you go.
"The market is too crowded."
Competition means there's a market. Differentiation beats domination.
"I'll do it when I have more time."
You won't. Time doesn't appear. You make time for priorities.
When Things Aren't Working
Let's say you've tried and it's not working. Nobody's buying. Growth is flat. What do you do?
First, make sure you're actually trying.
"It's not working" sometimes means "I haven't really launched." Have you put it in front of actual potential customers? Have you asked for sales?
If you have tried, ask: why isn't it working?
- Wrong customer? (You're talking to people who don't have this problem)
- Wrong message? (They have the problem but don't understand how you help)
- Wrong channel? (You're in the wrong places)
- Wrong product? (It doesn't actually solve the problem well)
- Wrong price? (Value doesn't match cost)
- Wrong timing? (They're not ready)
Each diagnosis leads to different actions.
Talk to people who didn't buy.
Not people who did (they'll tell you what you want to hear). People who didn't. Why not? What would have changed their mind?
Know when to stop.
This is the hardest judgment. When is persistence valuable and when is it denial? If you've tried multiple approaches, multiple customer segments, multiple value propositions, and nothing works - it might be time to move on.
Moving on isn't failure. Spending years on something that will never work is failure.
The Companies of One Future
I want to come back to something I mentioned in Part 2: the rise of companies of one.
This isn't a hypothetical. It's happening now. Technology has made it possible for individual operators to build real businesses serving real customers.
Not massive businesses. Not billion-dollar unicorns. But sustainable businesses that provide good incomes and solve real problems.
ReApply is a company of one. FitCheck is a company of one. I have no employees. No office. No investors. Just me, AI tools, and customers who find value in what I've built.
I think we're going to see many more of these. People with domain expertise, building for specific niches, using AI to extend what they can do alone.
If the traditional startup path (raise money, hire fast, grow or die) doesn't appeal to you, know that there's an alternative. It's not for everyone - it's lonely, you wear every hat, there's no safety net. But for some people, it's exactly right.
Your Next Steps
If you've read all three parts of this series, you've got a framework:
The rest is up to you.
Maybe you decide this isn't your path - that's a valid conclusion. Better to decide consciously than to drift.
Maybe you decide to explore further - talk to people, research the market, build something small. That's how most ventures start.
Maybe you decide to go all in - quit your job, burn the boats, bet on yourself. Just make sure you've done the validation first.
Whatever you decide, I hope this series has given you clearer thinking. Building something is hard. But it's also one of the most meaningful things you can do.
Good luck.
