Which commonly believed business myth causes the most financial damage?

Info

Among all business myths, the belief that “If you build it, they will come” is arguably the most financially damaging. This myth implies that building a great product or service guarantees customer interest and sales.

Why this myth causes financial harm:

  • Ignores marketing and distribution: Many founders spend large amounts of money and time building a product, expecting it to sell itself, only to realize there’s no traction.

  • Leads to poor resource allocation: Huge investments in product development without validating market demand lead to wasted resources and financial strain.

  • Customer feedback is overlooked: Assuming demand without engaging real users results in features no one wants or pricing no one will pay.

  • False confidence in innovation: Businesses that rely only on the perceived uniqueness of their product without competitive benchmarking end up blindsided.

Real-world implications:

  • Tech startups: Many startups fail after spending investor money on development but lacking a go-to-market strategy.

  • Retail businesses: Opening a store in a poor location or without promotion leads to unsold inventory and debt.

What to do instead:

  • Prioritize customer discovery and testing before heavy investments.

  • Use the Lean Startup approach—build a minimal version, test it, and iterate based on user data.

  • Develop a sales and marketing strategy in parallel with product development
