Customer development is a formal process of identifying potential customers and determining how to meet their needs using testable hypotheses. Entrepreneur and business professor Steve Blank highlighted the Customer Development Manifesto principles in The Startup Owner’s Manual as the core principles for modern startups.
| Element | Description |
|---|---|
| Concept Overview | Customer Development is a methodology for building and growing startups by systematically searching for a scalable and repeatable business model. It was developed by Steve Blank and is designed to help startups avoid failure by focusing on customer feedback, validation, and iteration. The key premise is that startups must first discover who their customers are and what they want before scaling operations. |
| Customer Discovery | Customer Discovery is the first phase of Customer Development. It involves identifying and validating the problem-solution fit by engaging potential customers in interviews and discussions. The goal is to gain insights into customer needs, pain points, and preferences. |
| Customer Validation | Customer Validation follows Customer Discovery. In this phase, startups seek to validate whether the proposed solution effectively addresses the identified customer problem. It includes creating prototypes or minimum viable products (MVPs) and testing them with real customers to collect feedback and assess product-market fit. |
| Customer Creation | Once validation is successful, the focus shifts to Customer Creation. This phase aims to build scalable and repeatable customer acquisition processes. Strategies for attracting and retaining customers are developed, and growth tactics are implemented to expand the customer base. |
| Company Building | The final phase is Company Building, where the startup transitions into a sustainable business. It involves scaling operations, optimizing processes, and setting a growth trajectory. The startup aims to become a fully-fledged company with a clear business model, revenue streams, and the ability to serve a broader market. |
| Implications | – Customer-Centric Approach: Emphasizes the importance of customer feedback and validation in building a successful startup. – Risk Mitigation: Helps identify and mitigate risks early in the startup’s development. – Iterative Process: Encourages continuous iteration and adaptation based on customer insights. – Scalability: Aims for scalable growth after validating the business model. |
| Benefits | – Reduced Failure Rate: Increases the likelihood of startup success by addressing customer needs from the start. – Efficient Resource Allocation: Ensures resources are invested in areas with validated customer demand. – Product-Market Fit: Facilitates the achievement of product-market fit, a critical milestone for startups. – Sustainable Growth: Provides a foundation for sustainable and scalable growth. |
| Drawbacks | – Time-Consuming: Customer Development can be time-intensive, especially in the early stages. – Requires Adaptability: Startups must be willing to pivot or change direction based on customer feedback, which can be challenging. – Market Risk: Success still depends on market dynamics, competition, and other external factors. – Skill Requirements: Requires expertise in customer research, validation, and marketing. |
| Use Cases | – Startup Development: Used by early-stage startups to navigate the path from idea to a sustainable business. – Product Launch: Applied to validate product ideas before launching them to a wider audience. – Business Model Testing: Assists in testing and refining business models for viability. – Innovation: Used to drive innovation within established companies by focusing on customer needs. |
Introducing the customer development manifesto

The customer development manifesto is the foundation of the lean startup.

Understanding customer development
Customer development is one of the three foundational elements of a lean start-up. However, many start-ups allocate too many resources to product or service development without first considering the needs of their target audience. Who is the ideal customer and what do features do they need? How can they be reached?
Ultimately, no product or service will ever be successful if no consumers are lining up to buy it. Even if the product in question does satisfy a need, is the size of the addressable market large enough to support it? Indeed, does the business have the ability to scale to meet demand if required?
Customer development addresses all of the above questions by discovering, testing, and validating assumptions that many organizations fail to verify.
The four steps of customer development
Customer development is built on the premise that the business must understand market needs and come up with multiple potential solutions. These solutions must have the capacity to be evaluated by testable hypotheses.
This is performed by implementing these four steps.
1 – Customer discovery
First, the vision of the start-up must form the basis of several purely hypothetical business models. Then, the hypothesis of each model should be tested and validated by understanding the needs of real or potential customers. The focus in customer discovery must remain on customer needs and not on technical features.
2 – Customer validation
As noted earlier, a product or service has to address customer needs and be viable. Customer validation is any method that allows the business to develop a predictable sales process.
Viability can be assessed by considering scalability, market fit, market size, feasibility, and repeatability. Furthermore, what is the weight of the problem? Is the product important? That is, will consumers be willing to part with money to own it? Hypotheses that fail customer validation are scrapped and the business must return to the first step.
3 – Customer creation
During the third step, the business must create demand among end-users and direct them through the preferred sales channel. Only after initial sales are made should efforts be made to increase product awareness. This helps control the cash burn rate and ensures that start-ups avoid spending money trying to attract customers from the wrong target audience.
Of course, every market is different. Some start-ups will need to put more thought into product positioning if there is pre-existing competition.
4 – Company building
In the final step of the customer development process, the business moves from an exploratory and testing phase to a phase of execution.
In other words, the business must fill roles in newly created departments such as sales, marketing, customer service, and business development. This naturally leads to the business beginning to scale up, spending more money on marketing and advertising to drive sales.
With a high demand for a product or service, the business moves from a start-up to a company executing on a verified and validated model.
