8 Powerful Lessons Every Entrepreneur Needs to Build a Lean Startup
Every day, new entrepreneurs dive into the business world armed with groundbreaking ideas for products or services. Yet, despite their passion and ambition, most lack the proper tools to build a lasting and successful business. That’s where Eric Ries comes in.
Ries, who’s seen firsthand the ups and downs of the startup world, has turned his own experiences—both failures and successes—into a formula that can help you build a business that lasts. His approach, as laid out in his book The Lean Startup, offers a strategic framework that allows you to avoid the mistakes most new businesses make and gives you the tools to build a sustainable growth strategy. The Lean Startup approach is designed to help you develop a viable product while ensuring your business’s foundation is strong.
In this post, we’ll walk through the key principles of Lean Startups and how you can apply them to your business today.
What Does It Mean to Run a Lean Startup?

According to Ries, a Lean Startup operates under five key principles. These aren’t just theoretical ideas; they’re the foundation for how you can start, build, and grow your own business.
Entrepreneurs Are Everywhere
Entrepreneurs are not just the ones you read about in magazines or books; they’re in every corner of society. Whether they’re someone who’s just lost their job and is taking the leap of faith into business, or a corporate executive looking to innovate, entrepreneurs are everywhere. And that’s a key mindset shift—entrepreneurship isn’t about having a specific title; it’s about creating new value.
Entrepreneurship Is Management
Building a business is a process, not just an idea. It’s about management—creating a system that can drive the business toward sustainability and scalability. This principle is at the heart of successful businesses, emphasizing the importance of structure in a world of rapid technological change. Having a solid management plan is just as crucial as having a great product.
Startups Are About Learning, Not Just Money
A startup’s primary goal isn’t just to make money or serve customers—it’s about learning how to build a sustainable business. Early on, you don’t know what works and what doesn’t. Through experimentation and learning, including innovation accounting, you’ll discover what your business needs to succeed.
Build-Measure-Learn Feedback Loop
The Lean Startup approach stresses the importance of the build-measure-learn feedback loop. Instead of perfecting your product and then launching, the Lean Startup method urges you to build a basic version, get it into the market, measure the results, and learn quickly. The faster you get through this cycle, the quicker you’ll understand what the market actually wants—and improve your chances of success.
Innovation Accounting
Innovation isn’t just about creating something new—it’s about measuring progress and making decisions based on real data. Tracking milestones, measuring your efforts, and prioritizing feedback from real customers is what makes a business successful. Without these metrics, you’re simply throwing ideas into the wind and hoping they work.
The Foundation of Your Startup
Before you dive into the details, you need to understand who your product is for. It’s vital to create a customer archetype—a clear picture of the person or business you’re building for. This helps guide your product development and resource allocation from the start.
As you move forward, you’ll need to take a leap of faith. No matter how much research you do, there are unknowns. To minimize risks, you can use analogs and antilogs. For example, when Apple was building the iPod, they took inspiration from the Sony Walkman (the analog), but had to make assumptions about whether people would pay for music (the antilog).
Next, build a Minimum Viable Product (MVP)—a version of your product that’s good enough to gather real market feedback. Nick Swinmurn, the founder of Zappos, started his online shoe business with nothing more than a website and photos of shoes from local stores. This allowed him to test the market with minimal risk and cost.
The Power of Data
Once you’ve launched your MVP, it’s time to measure your results. But not all metrics are created equal. Ries emphasizes the importance of focusing on actionable, accessible, and auditable metrics—data that gives you clear insights into what’s working and what’s not.
For example, in the early days of his company IMVU, Ries tracked key metrics like registration, activation, and retention. These gave him insights into how many people were signing up, logging in, and sticking with the service. With metrics like these, you can make informed decisions about how to pivot or persevere with your business strategy.
The Key Decision

At some point, you’ll need to make a critical decision: Do you pivot or persevere? A pivot is a fundamental change in strategy, and it’s often necessary if your original business idea isn’t yielding the results you want.
There are many types of pivots, including:
Zoom-in Pivot: When a single feature of your product becomes the entire product.
Zoom-out Pivot: When your product is too narrow, and you need to broaden your scope.
Customer Segment Pivot: When you realize that a different group of customers would benefit more from your product.
Technology Pivot: When you find a more efficient or cost-effective way to solve your problem.
If your initial idea isn’t working, it’s important to pivot quickly and move towards something that has the potential to succeed.
Sustainable Business Expansion
Once you’ve found a business model that works, it’s time to scale. Ries outlines three types of growth engines that can help you do this:
Sticky Growth Engine: Retaining customers and getting them to keep coming back for more.
Viral Growth Engine: Relying on your current customers to bring in new ones.
Paid Growth Engine: Using profits to reinvest in marketing and customer acquisition.
Each model requires a different focus, but understanding which one suits your business is crucial for sustainable growth. Lean Startups thrive on adapting their growth engines to fit their goals.
Applying Lean Startup Principles to Your Business
If you’re looking to build a lasting, successful business, the Lean Startup model provides a roadmap. From creating a Minimum Viable Product to using the build-measure-learn feedback loop to make informed decisions, the Lean Startup approach gives you the tools to experiment, learn, and pivot when necessary.
