Part One: Vision; Overcoming the Illusion of the Perfect Business Plan
When many of us hear the word “startup”, we picture a group of young geniuses in a dark garage, writing code for a revolutionary software, who suddenly become billionaires overnight. In his book “The Lean Startup”, Eric Ries puts an end to this Hollywood myth.
Ries begins his story with a bitter confession. Early in his career, he spent immense time, energy, and millions of dollars building products that ultimately no one wanted to use. He and his team worked in secret for months, drafted a flawless Business Plan on paper, built the product with every conceivable feature, and when they proudly launched it to the market… they were met with dead silence. Nobody wanted their product!
This is exactly where the spark of a new mindset was lit in his mind: “What if, instead of assuming we know what the customer wants, we use a scientific method to discover their true desires?”
Defining a Startup from Eric Ries’s Perspective
One of the biggest misunderstandings in the business world is considering a startup merely as a scaled-down version of a large corporation. Ries, however, offers a completely different definition:
“A startup is a human institution designed to create a new product or service under conditions of extreme uncertainty.”
The keyword in this definition is “uncertainty”. When a global automotive company like Ford wants to produce a new model, it knows exactly who the customers are, how big the market is, and what the competitors are doing. But when you are creating a new platform or an innovative service, you are walking in absolute darkness. In such conditions, writing five-year plans and precise financial forecasts is nothing but wasting time and deceiving yourself.
The Deadly Trap of Business Plans
In traditional management, we are taught that we must have a detailed plan before starting anything. However, Eric Ries argues that in the startup ecosystem, business plans only work if future conditions perfectly mirror the past—an absolute impossibility in the world of innovation.
This is where the “Lean” approach comes into play. The lean concept, rooted in Toyota’s manufacturing system, is based on a simple principle: eliminating anything that does not create value for the customer. In the startup world, any effort that does not lead to validated learning about the customer is an absolute waste.
Validated Learning
The best global example for this concept is the origin story of Dropbox. Drew Houston, the founder of Dropbox, knew that building a file-synchronization infrastructure was incredibly complex and expensive. Instead of spending months building the final product, he simply recorded a 3-minute video showing how the product was supposed to work. He published the video just to see if anyone was even interested in the idea. The result? Their waiting list skyrocketed from 5,000 to 75,000 people overnight!
This is precisely what Ries calls Validated Learning. You shouldn’t measure your success by the number of hours worked, lines of code written, or beautiful graphic designs. The only true measure of progress in a startup is: How effectively and affordably have you been able to test your assumptions about customers in the real world?
💡 Note from Hamed Asghari (CEO of Stinoment)
One of the biggest traps founders and managers worldwide fall into is “falling in love with the product” rather than “falling in love with the customer’s problem.” At Stinoment, we have seen time and again how early-stage businesses lock all their capital and energy behind closed doors to build a “perfect and flawless” product. They forget that perfectionism in the early days is the number one enemy of innovation.
In today’s fast-paced global economy, the “build in stealth and launch big” strategy no longer works. Markets are too ruthless to wait for your idea to be perfected. If you are not embarrassed by the first version of your product, you’ve launched too late. The biggest risk in modern business is not having your idea stolen; it is building a product only to realize post-launch that no one on earth is willing to pay for it. Agility and rapid learning are the only valid currencies in today’s business landscape.
