If you’re a founder or thinking of starting a business, here’s the truth: Investors don’t care about your pitch deck as much as you think. They care about one thing: Traction.

Josh Payne, an angel investor, recently shared 10 red flags that make investors walk away. But beyond impressing investors, these red flags also highlight the key mistakes that kill businesses before they even start.

If you’re building a startup, this is the best reality check you’ll get. Let’s break it down.

1. No Real Customers, Only ‘Vision’ and Fancy Slides

A startup without customers is like a restaurant with no food, it might look nice, but no one is eating.

Many founders spend months crafting the perfect pitch decks and landing pages, but investors (and even customers) are not impressed by what you plan to do. They want proof. Show paying customers. Even better, show customers coming back.

💡 Fact: Research shows that 42% of startups fail because there is no market need for their product (CB Insights).

💡 Takeaway: Focus on getting actual customers. If people aren’t willing to pay for your product, you’re not solving a real problem.

2. No Path to Profitability

Imagine raising $100 million, yet your business is still burning money like Lagos traffic burns patience. That’s the story of many startups that eventually collapse.

Investors want to know:

  • How will you make money?

  • When will you be profitable?

  • How will you sustain growth?

Without answers to these, you’re just running on vibes.

💡 Fact: In 2023, over 400 tech startups shut down globally due to lack of a profitable business model (Crunchbase).

💡 Takeaway: Growth is important, but cash flow is king. If your business doesn’t generate money, you’re not building a business, you’re running an expensive experiment.


3. Founders Who Won’t Sell

If you’re scared to sell your own product, who will?

Sales is not just for your sales team, it’s a founder’s job. The best founders sell their vision to:

  • Customers (to drive revenue)

  • Employees (to build a strong team)

  • Investors (to secure funding)

💡 Quote: "If you can’t sell, you can’t build a business." – Mark Cuban

💡 Takeaway: Selling is non-negotiable. Get comfortable with it.


4. No Differentiation (‘We’re Like Uber, But Cheaper’)

Copycats don’t win. If your only edge is price, you will lose, because someone else will come and undercut you.

Instead, ask yourself:

  • What makes us truly different?

  • What do we have that competitors don’t?

  • Why should customers choose us over others?

💡 Example: When Slack launched, it wasn’t just another messaging app, it was built specifically for team collaboration, which made it stand out.

💡 Takeaway: If your product isn’t solving a unique problem, you don’t have a business.


5. No Urgency (‘We’re Exploring Ideas’)

Founders who succeed act like time is running out. If you’re still thinking about launching or considering raising funds next year, someone else is already taking action.

💡 Quote: “The best way to predict the future is to create it.” – Peter Drucker

💡 Takeaway: Move fast. If you take too long, the market will leave you behind.

6. Raising Money Before Proving Anything

Too many founders believe that funding solves all problems.

🚨 Reality check: If your business can’t survive without funding, it’s not a business—it’s a risky experiment.

💡 Fact: Investors prefer to fund businesses that have already gained traction, not just ideas on paper.

💡 Takeaway: Focus on proving your concept first before looking for external funding.


7. No Clear Distribution Strategy

Many founders think a great product will sell itself. It won’t.

The best founders don’t just build, they obsess over distribution:

  • How will people discover your product?

  • How will you acquire customers?

  • How will you retain them?

💡 Example: Dropbox grew to 4 million users in 15 months using a simple referral program.

💡 Takeaway: Your product is only as good as your ability to distribute it.


8. No Ownership Mentality

If a founder’s response to challenges is “We need to hire someone for that”, it’s a red flag.

Great founders:

  • Learn new skills before outsourcing

  • Solve problems before delegating

  • Own the process before handing it off

💡 Quote: “A CEO does whatever it takes to move the company forward.”

💡 Takeaway: Before you hire someone, understand the role yourself.


9. A CEO Who Can’t Attract Talent

Your first 5–10 hires can make or break your company.

If talented people don’t want to join you, it could mean:

  • Your vision isn’t strong enough

  • You’re not a leader people trust

  • Your company isn’t exciting to work for

💡 Fact: Over 90% of successful startups had strong founding teams in the early days (Harvard Business Review).

💡 Takeaway: If you can’t convince great talent to join you, it’s a problem.


10. No Skin in the Game

If a founder won’t invest their own money, take a pay cut, or make sacrifices, why should investors take the risk?

💡 Example: Elon Musk poured his last $35 million into Tesla when it almost collapsed.

💡 Takeaway: Investors and customers will only believe in you if you believe in yourself first.
