While discovery experiments can point you in the right direction, validation experiments provide stronger evidence that your business idea will succeed in the market. As you move from initial exploration toward more substantial investment, you need increasingly robust evidence that customers will actually use and pay for your solution.
As Sallie Krawcheck, founder of Ellevest, aptly puts it: “Knowing your customer inside and out is mission-critical, and it takes time.” Validation experiments bridge the gap between preliminary market research and full product development, giving you confidence to proceed with larger investments.

When to Move from Discovery to Validation
The transition from discovery to validation should happen when:
- Your discovery experiments have shown consistent positive signals
- You’ve identified a specific customer segment with a clear problem worth solving
- You have a well-defined value proposition that resonates with potential customers
- You’re ready to invest more resources to generate stronger evidence
Validation experiments typically require more time, money, and effort than discovery experiments, but they provide much stronger evidence of market demand and business viability.
Four Powerful Validation Experiments
Let’s explore four validation experiments that generate compelling evidence without requiring full product development:
1. Clickable Prototypes: Making Your Idea Tangible
A clickable prototype simulates the core user experience of your product without requiring backend development. This approach allows potential users to interact with your solution and provide feedback based on actual experience rather than abstract concepts.
How to implement:
- Create screen designs for the key user flows in your product
- Use prototyping tools like Figma, Adobe XD, or Invision to connect screens and create interactive elements
- Develop 3-5 specific tasks for users to complete with the prototype
- Observe users attempting these tasks, noting points of confusion or delight
- Collect quantitative data (task completion rates, time on task) and qualitative feedback
Key insight: A clickable prototype generates much stronger evidence than conceptual discussions because you’re observing actual user behavior rather than collecting opinions.
Case Study: Before developing their personal finance app, Mint created a clickable prototype focused on their core value proposition: aggregating financial accounts in one place. By observing users interact with the prototype, they discovered that initial security concerns were quickly overcome once users saw how the dashboard would simplify their financial management. This insight informed both their product development priorities and marketing messaging around security and convenience.
2. Wizard of Oz: Fake It Till You Make It
A Wizard of Oz experiment creates the illusion of a functioning product while manually performing operations behind the scenes. This approach allows you to test market demand and refine your offering before investing in complex technology.
How to implement:
- Create a customer-facing interface that appears to be automated
- Manually fulfill requests or provide services behind the scenes
- Set clear internal processes for handling customer interactions
- Document the time, cost, and challenges of manual fulfillment
- Collect customer feedback on the experience
Key insight: Unlike a concierge test (where customers know humans are involved), in a Wizard of Oz test, customers believe they’re interacting with an automated system, providing truer validation of your intended solution.
Case Study: Zappos founder Nick Swinmurn started with a simple Wizard of Oz experiment. Instead of building inventory and warehousing, he photographed shoes at local stores and posted them online. When customers ordered, he would purchase the shoes from the physical stores and ship them to customers. This approach validated customer willingness to buy shoes online before Zappos invested in inventory and infrastructure.
3. Single-Feature MVP: Testing Your Core Value
A Single-Feature MVP delivers just one core functionality of your product – the element that provides the most value and differentiates your solution from alternatives.
How to implement:
- Identify the single most important feature that delivers your core value proposition
- Build a functional version of just this feature, ignoring secondary features
- Release it to a limited group of target customers
- Track usage metrics and collect feedback
- Evaluate whether this single feature provides enough value to drive adoption
Key insight: By focusing on just one feature, you significantly reduce development time and cost while still testing your most critical value hypothesis.
Case Study: When Dropbox was first developing their cloud storage solution, they focused exclusively on one core feature: seamless file synchronization across devices. They intentionally excluded many features that would later become part of the product (sharing, collaboration tools, etc.) to validate their primary hypothesis that users wanted frictionless file access across multiple devices. This focused approach allowed them to validate their core value proposition before expanding the product’s feature set.
4. Presale: The Ultimate Validation
A presale involves selling your product before it’s fully built, providing the strongest possible validation of market demand – actual customer purchases.
How to implement:
- Create a compelling landing page explaining your product and its benefits
- Set up a payment system to accept orders or deposits
- Be transparent about delivery timelines and what customers can expect
- Consider offering early-bird pricing or exclusive benefits for presale customers
- Document conversion rates at each stage of the purchase funnel
Key insight: While presales generate the strongest evidence of market demand, they also create commitments to deliver, so ensure you can fulfill these promises.
Case Study: Pebble, one of the first successful smartwatch companies, used Kickstarter to presell their product before manufacturing. They sought $100,000 but raised over $10 million from 69,000 backers, providing undeniable validation of market demand along with the capital needed for production. This approach not only validated their product concept but also created a community of early adopters who provided valuable feedback for future iterations.
From Evidence to Confidence: Building a Progressive Testing Strategy
The most effective testing strategies combine multiple experiments to build increasing levels of evidence over time. Consider this progressive approach:
- Start with discovery (Customer interviews → Online ad testing → Search trend analysis)
- Move to low-cost validation (Clickable prototype → Wizard of Oz)
- Confirm with high-commitment validation (Single-feature MVP → Presale)
Each stage builds upon insights from previous experiments, creating a compounding body of evidence that reduces risk and increases confidence in your business idea.
Adapting Validation Approaches by Business Type
Different business models require tailored validation approaches:
For B2C Software:
- Use clickable prototypes to test user experience
- Deploy single-feature MVPs to validate core value
- Run presales campaigns to confirm willingness to pay
For B2B Solutions:
- Secure letters of intent from potential clients
- Implement concierge delivery for initial customers
- Develop case studies based on early implementations
For Physical Products:
- Create realistic prototypes (3D printing, mock-ups)
- Run crowdfunding campaigns to validate demand
- Use pop-up stores for direct customer interaction
Balancing Speed and Evidence Quality
While validation experiments require more investment than discovery experiments, they shouldn’t become mini product launches. Remember these principles:
- Focus on learning, not perfection: Your validation prototypes don’t need to be flawless
- Test the riskiest elements first: Prioritize experiments that address your biggest uncertainties
- Set clear success criteria before experimenting: Define what evidence would justify moving forward
- Be transparent with test participants: Set appropriate expectations about the experimental nature of what they’re experiencing
Moving from Validation to Execution
How do you know when you’ve done enough validation to move into full execution mode? Look for these signals:
- Consistent positive evidence across multiple experiments
- Strong indicators of willingness to pay (presales, deposits, pricing feedback)
- Clear understanding of customer acquisition channels and costs
- Validated unit economics that support a sustainable business model
- Manageable technical and operational requirements
Even after moving to execution, maintain a testing mindset. The most successful companies continue experimenting throughout their lifecycle, continuously validating new features, markets, and business model innovations.
