Launching a business can feel like strapping into a rocket—equal parts thrilling and terrifying. But before you fuel up, ask yourself: does this idea even have legs? Not just one or two. You need four solid ones to keep your business standing through real-world bumps and pivots.

Think of this as a pre-flight checklist for entrepreneurs—an idea stress-test built around four crucial legs: Demand, Distribution, Differentiation, and Dollars.

1. Demand: Does anyone actually want what you're selling? And no, your mom’s enthusiasm doesn’t count as validation. You need clear evidence of customer demand. This can come from:

   • Keyword research (are people searching for your solution?)

   • Early sales or waitlists

   • Conversations with real potential customers

   • Existing pain points in the market

According to the Harvard Business Review, 42% of startups fail because there's no market need for their product. That’s nearly half of all new ventures. CB Insights confirms this is the number one cause of startup death.

Try tools like Google Trends and Answer the Public to get a sense of what your audience is already talking about. If you’re not solving a burning problem, you’re probably building a very elegant solution to something nobody cares about.

2. Distribution: Even if people want your product, can you actually get it in front of them—consistently and affordably?

In his book Zero to One, Peter Thiel famously said, “Poor distribution—not product—is the number one cause of failure.” Don’t be that startup with a great product and no customers because you underestimated how hard it is to cut through the noise.

Distribution channels can include:

• Paid ads (if the margins make sense)

• SEO/content marketing

• Direct sales

• Influencer partnerships

• B2B outreach

3. Differentiation: Let’s be blunt: if your startup sounds just like the next guy’s, you’re headed for mediocrity.

You must clearly answer: “Why would someone pick us instead of the competition?”

Is it:

• Price?

• Brand story?

• Features?

• Delivery model?

• Convenience?

Positioning matters. Take time to read April Dunford’s classic book, Obviously Awesome, or skim her excellent podcast interviews like this one on Lenny’s Podcast.

Standing out doesn't mean being outrageous—it means being precise about your edge.

4. Dollars: Finally, the cold hard math: does this idea make money? Will it ever?

You’d be shocked how many founders skip this part.

"We’ll figure it out later" only works if you’re a VC darling with deep pockets.

Use a simple formula:

(Expected revenue per user × # of users) – Costs = Enough to survive?

You can prototype this with free tools like the Lean Canvas or a basic spreadsheet.

And remember: Profit ≠ Cash Flow. You can be profitable and still go bankrupt because of timing. Learn how to read a basic cash flow statement—here’s a great explainer from Bench.

Before you register a domain or print business cards, pressure-test your concept. A solid business doesn’t hobble into the market—it walks on four legs, confidently.

Need a checklist version of this? Let me know. Or better yet, run your idea through this framework and share where you’re stuck. That’s where the real clarity lives.
