When you’re in the early stages of building a startup, your most precious resources aren’t just money and time – it’s your capacity to learn quickly about your market before your runway disappears. The harsh reality? Most founders invest too heavily in building solutions before confirming there’s a problem worth solving.
As legendary jazz musician Herbie Hancock wisely noted, “The problem happens when you don’t put that first note down. Just start!” The same applies to testing business ideas – you need to start with lightweight discovery experiments before making major investments.

The Power of Discovery Experiments
Discovery experiments are quick, inexpensive tests designed to give you initial insights into your business hypotheses. They won’t provide definitive proof, but they’ll point you in the right direction when uncertainty is highest.
The beauty of discovery experiments is their efficiency. You can run many of them in parallel, generating multiple learning points for a fraction of what it would cost to build even a minimal version of your product.
Five Essential Discovery Experiments for Early-Stage Founders
Let’s explore five powerful discovery experiments that should be in every founder’s toolkit:
1. Customer Interviews: The Foundation of Discovery
Customer interviews remain the cornerstone of early validation, yet most founders conduct them incorrectly. Effective customer interviews aren’t about pitching your solution or asking hypothetical questions about future behavior. They’re about understanding current problems, workflows, and pain points.
How to implement:
- Identify 10-15 potential customers in your target segment
- Prepare a discussion guide focused on understanding their current behaviors and pain points
- Ask open-ended questions about specific past experiences, not hypothetical future choices
- Document patterns and insights, particularly around frequency and severity of problems
- Look for evidence of existing workarounds or “hacks” that indicate unmet needs
Key insight: When customers are already cobbling together imperfect solutions to a problem, that’s strong evidence of a real need worth addressing.
2. Online Ad Testing: Validate Messaging at Low Cost
Before building anything, test whether your value proposition resonates with potential customers through targeted online ads. This approach allows you to experiment with different messaging and gauge interest at minimal cost.
How to implement:
- Create 3-5 different ad variations that highlight different aspects of your value proposition
- Set up a simple landing page with an email signup form
- Run limited ad campaigns ($100-300) targeting your hypothesized customer segments
- Track click-through rates and signup conversions for each value proposition
Case Study: When Neil Patel was developing his SEO tool Ubersuggest, he tested 21 different value propositions through Google Ads before building the product. This allowed him to identify which specific pain points and benefits resonated most strongly with his target audience, shaping both his product development priorities and marketing strategy.
3. Discussion Forums: Mining Existing Conversations
Customers are already discussing their problems online. By analyzing relevant discussion forums, Reddit threads, industry groups, and social media conversations, you can gather unbiased insights about pain points and desired solutions.
How to implement:
- Identify 5-10 online communities where your target customers congregate
- Search for discussions related to the problem you’re solving
- Analyze complaints, questions, and workarounds mentioned by community members
- Document the language and terminology customers use to describe their problems
- Note the frequency and intensity of discussions around specific pain points
Key insight: The exact language customers use to describe their problems provides invaluable copy for your marketing materials and product descriptions.
4. Search Trend Analysis: Validating Market Interest
Before investing in SEO or content marketing, analyze search trends to determine if people are actively looking for solutions to the problem you’re addressing.
How to implement:
- Use tools like Google Trends, Keyword Planner, or Ahrefs to research relevant keywords
- Analyze search volume trends over time (growing, stable, or declining?)
- Examine related searches to understand how customers frame their problems
- Compare search volumes across different geographic regions
- Look for seasonal patterns that might affect your business
Case Study: The founders of Airbnb validated part of their concept by examining search trends for terms related to travel accommodations during major events. They discovered significant spikes in searches for affordable lodging during conferences and festivals, confirming their hypothesis about demand during peak periods when hotels were fully booked.
5. Feature Stub: Testing Interest in New Features
A feature stub is a non-functional button or link in an existing product or website that gauges interest in a potential new feature before you build it.
How to implement:
- Add a button or link for the proposed feature in a visible location
- When users click, present a message explaining the feature is coming soon with an option to sign up for updates
- Track click rates and signup conversions
- Optional: Add a brief survey asking why they’re interested in the feature
Key insight: This approach works particularly well for existing products considering new features, but can also be adapted for new products by placing “coming soon” features on landing pages.
Balancing Evidence Strength and Investment
Discovery experiments typically produce what testing experts call “weak evidence” – they suggest directions rather than provide definitive proof. However, their low cost and quick execution make them ideal for early-stage validation.
The goal at this stage isn’t certainty; it’s direction. You’re trying to identify which hypotheses merit further investment in more resource-intensive validation experiments.
Case Study: How Product Hunt Started as an Email List
Ryan Hoover created Product Hunt, later acquired for a reported $20 million, by starting with perhaps the simplest discovery experiment possible: an email list.
Before building a platform, Hoover spent just 20 minutes setting up a group on Linkydink (a link-sharing tool) and invited startup friends to contribute product discoveries that were sent as a daily email. Within two weeks, over 200 people had subscribed, and 30 contributors were actively sharing discoveries.
This minimal experiment validated his hypothesis that product enthusiasts wanted a dedicated community for sharing and discussing new products. Only after seeing engagement with this simple experiment did Hoover invest in building the actual Product Hunt platform.
Implementing Discovery Experiments in Your Startup
To maximize learning from discovery experiments:
- Run multiple experiments in parallel: Different experiments validate different aspects of your business model
- Start with the riskiest hypotheses: Focus first on assumptions that could invalidate your entire business concept
- Combine qualitative and quantitative approaches: Numbers tell you what’s happening; conversations tell you why
- Document everything: Create a shared knowledge base of customer insights
- Be willing to disconfirm hypotheses: The goal is learning, not validation
Remember, at the discovery stage, being wrong quickly is more valuable than being wrong slowly. Each experiment, whether it confirms or contradicts your hypotheses, increases your understanding of the market and reduces your risk of building something nobody wants.
