In our new blog series, we aim to help startups navigate the network of unavoidable concepts, methods, and challenges in the startup ecosystem. In our second blog post, we introduce the lean startup methodology, which is closely related to the Problem-Solution Fit discussed in our previous post.
What is the Lean Startup Methodology?
The method’s predecessor is a combination of Customer Development and Lean Management, which was originally designed for large corporations. It even helped the resource-strapped Toyota car factory in post-World War II Japan restart production. The Lean Startup methodology adopted principles such as minimizing waste, continuous improvement, and active learning from consumer feedback. Eric Ries ultimately adapted this methodology to the startup ecosystem, providing a framework for how to turn an idea into a business (startup) quickly and cost-effectively.
Core principles of the Lean Method
- Anyone can be an entrepreneur: The methodology can be applied to any organization that provides new products or services in an uncertain environment. Think, for example, of Amazon or Apple testing new technologies.
- Management is as important as the product/service: Just like any business, startups also require management. A startup is an organization, so it needs structured management as well.
- Validation through learning: A fundamental element of startups is learning how to build a sustainable business. Experimenting with and testing different parts of the idea is essential.
- Setting milestones and measuring progress: Innovators are responsible for their work, and it is important to track their progress.
Build, measure, learn
The methodology breaks product development into three cycles: build, measure, and learn, which continuously repeat. These cycles should be as short as possible, and it’s crucial to measure as soon as possible whether the solution is valuable to customers and whether the idea is working. If it isn’t, immediate changes must be made.
Build: A product experience based on previous research, test results, and experiments.
Measure: The reaction and feedback from targeted customers regarding the product experience.
Split test (A/B testing): Testing different solutions with different groups, such as various website designs, and using feedback to evaluate the product.
Funnel Analysis: Identifies the path customers take to reach the product. The goal of “funnel analysis” is to determine at what points potential customers drop off and why.
Cohort Analysis: A type of behavioral analysis where user groups are examined based on shared characteristics to better track and understand their actions.
Net Promoter Score: Measures brand loyalty and customer satisfaction.
Learn: Learning from the collected data.
Conducting customer interviews
5 Whys Root Cause Analysis: Asking a series of questions where each answer prompts a new question, leading to the identification of the “root causes.”
Lean Startup Methodology vs. Traditional Methods
Turning ideas into businesses (startups) can be a long and chaotic process. However, this method helps bring structure, providing tools for continuous measurement and testing. It replaces the “just do something” approach with a more conscious strategy.It also reduces uncertainty, one of the biggest challenges in today’s startup world. Studies show that most startups fail due to lack of product-market fit. This methodology helps mitigate initial risks by ensuring that the product meets customer needs before launch.
Cheaper and Faster Product Development & Validation: The method distinguishes between what can be done and what should be done. Founders often become emotionally attached to their ideas, which can lead to biased decision-making. To avoid wasting resources, it’s crucial to conduct objective tests that validate ideas.
Customer Involvement Offers Additional Benefits: Engaging customers fosters commitment, creates stronger emotional bonds between customers and the company, and leads to long-term relationships, increased brand loyalty, and better profitability.
Even though startups are small, they require management. Instead of imitating large corporations in smaller steps, startups should create an organization that fits their ecosystem (rapid change, growth) and supports innovation.
How to use Lean Startup Methodology?
Failure is Not the Enemy, but an Opportunity to Learn! Integrate what you learn into your business for faster growth! Ensure that team members approach experimentation with the same mindset as the founders. Ideally, build your company culture around this approach.
Initially, entrepreneurs should compile hypotheses about their (future) business and structure them in a business model. This model illustrates how the startup intends to create value.
Test your model! Hypotheses can be adjusted or replaced based on customer feedback. Through an agile development process, the startup creates a Minimum Viable Product (MVP)—a basic version of the product that allows for early testing and learning.
An MVP is an early version of a product/service that reflects key features of the final product, making it suitable for gathering valuable consumer feedback. The goal of testing the MVP is to find Problem-Solution Fit (PSF).
Once this is established, the next step is achieving Product-Market Fit (PMF)—not just ensuring the solution effectively solves a problem, but determining whether there is actual market demand for it.
Continue the Build-Measure-Learn Cycle! Throughout this process, it's vital to maintain continuous communication with customers. Don’t rely on blind assumptions—ask potential customers if they are interested in your product and whether they’d be willing to pay for it.
Potential challenges:
- Choosing the right target audience and recruiting enough test subjects can be difficult at first.
- Prioritizing decisions and setting the right focus is not always easy.
- If a startup is not structured for fast iteration and adaptation, the Lean Startup method may be difficult to implement. The organization must be flexible, but the methodology should also be adapted to fit the specific startup.
- For revolutionary innovations, the method has some limitations: testers must be open-minded and fully understand the product/service.
- If an MVP fails to capture customers’ interest, it can generate negative perceptions before the product even launches.
- Negative feedback can be discouraging and reduce a founder’s motivation. However, it’s important to learn from constructive criticism and accept that not everyone will love the product. False positive feedback (politeness bias) can also be misleading.
- Customer feedback should be carefully evaluated: Is it the opinion of many or just one person? Is it worth implementing? Don’t get lost in minor details!
- The iterative cycle can become endless, leading to an endless development spiral where there is always something to improve. It’s crucial to recognize when the initial product development phase is complete.
Did You Know?
Many Successful Startups Use the Lean Startup Method.
Dropbox: Thanks to this methodology, Dropbox grew from 100,000 registered users to over 4,000,000 in just 15 months.
Wealthfront: Founded in 2009, Wealthfront currently manages over $200 million and processes more than $2 million in transactions daily.
IMVU: Reached 50 million registered users and generates over $40 million in annual revenue.
From experiments to expression
The Lean Startup process helps you refine your product through testing and feedback, but communicating what you’ve learned is just as important. Turning validated insights into a clear and consistent story builds trust with customers, partners, and investors alike. Our CMO Partner service supports startups in shaping authentic communication and a strong personal brand that evolves with their growth.
