Validating a startup idea does not always require expensive market research, months of product development or a large initial investment.
Anupam Mittal, founder of Shaadi.com and an experienced startup investor, suggests a much simpler approach: test your idea with real people and look for genuine market signals before investing heavily.
His framework focuses on low-cost experiments such as WhatsApp groups, online communities, product mockups, landing pages, small-batch sales and offline tests. The objective is to discover whether customers actually want the product and, more importantly, whether they are willing to pay for it.
Key Highlights
Use WhatsApp groups to test an idea with potential customers at almost zero cost.
Use online communities to get feedback from people who do not personally know you.
Create product mockups before investing in inventory.
Build a realistic landing page and test whether people try to place an order.
Test different prices to understand customers' willingness to pay.
Make a small batch and attempt to sell it before scaling production.
Use posters, phone numbers and QR codes to validate local demand.
Service businesses can sell their offering first and build the backend as they acquire customers.
The goal of validation is to collect real market signals before committing significant time and capital.
What Is Anupam Mittal's Approach to Startup Idea Validation?
The basic principle is simple: do not overcomplicate validation.
Instead of spending months trying to prove that an idea will work, founders can create small experiments and put the idea in front of potential customers.
For example, a founder could create a WhatsApp group, share product concepts and ask people for their reactions. They can then move beyond their personal network and test the idea with relevant online communities.
The next step is to create something that looks like the real product — even if the product itself is not ready — and see whether customers are willing to take an action such as placing an order.
This creates a difference between people saying they like an idea and people showing genuine interest in buying it.
- Test the Idea Through WhatsApp*
*
One of the simplest validation methods is creating a WhatsApp group with potential customers.
A founder can share product images, branding concepts, positioning and other basic information and then ask members what they think.
For example, someone planning to launch a spicy sauce could create a simple product visual and present the concept to a group of potential customers.
The advantage is that the experiment can be conducted without spending heavily on advertising or research.
- Get Feedback From Strangers*
*
Friends and family can provide useful feedback, but their opinions may not always represent the broader market.
Anupam suggests taking the idea into relevant communities on platforms such as Facebook, Instagram, Reddit and WhatsApp.
For example, a food startup could find communities of food enthusiasts and show them product concepts.
The objective is to find people who have no personal connection with the founder but still show genuine interest in the product.
Their questions, reactions and willingness to engage can provide useful early validation.
- Build a Fake-but-Functional Product*
*
A founder does not always need inventory or a finished product to test demand.
Instead, they can create a realistic website using product images, videos, branding and positioning.
The website should look like a genuine business and allow visitors to attempt to place an order.
This provides a stronger signal than simply asking people whether they like the idea.
If someone actually attempts to buy the product, the founder has evidence of commercial interest.
- Test Willingness to Pay*
*
The most important validation question is not
"Do people like my idea?"
It is
"Will people pay for it?"
A landing page or simple sales experiment can help founders understand how many people are willing to purchase and what price they are comfortable paying.
Different prices can also be tested to gather more information about customer willingness to pay.
If the product is not ready, the founder can explain that it is still being prepared and retain interested customers as early users.
5. Make a Small Batch Before Scaling
For physical products, founders can start with a small production run instead of immediately investing in large-scale manufacturing.
Anupam gives the example of a product such as almond butter, where a founder can make a small batch and test it within existing communities.
The objective is to move quickly from an idea to an actual transaction.
Even a small number of sales can reveal information about demand, pricing and customer response before the founder invests more capital.
6. Use Offline Validation for Local Businesses
Digital validation is not necessary for every business.
For a local product or service, a simple poster can be enough to test demand.
A founder can put up a poster in a relevant physical location with
Product or service details
Price
Phone number
QR code or other contact method
The number of calls, messages or enquiries can then be used as an early demand signal.
This allows founders to test a local market without spending heavily on infrastructure or advertising.
7. Sell the Service Before Building Everything
Service businesses can use a slightly different validation approach.
Instead of building the complete backend first, founders can create a website, pitch deck or service offering and begin approaching potential customers.
Once a customer agrees to pay, the founder can work out how to deliver the service.
Anupam relates this to his own experience of starting an IT services company. His team initially had only a few people, but they focused on selling websites and other technology services before having all the capabilities figured out.
8. Your First Customer Can Help You Build the Product
The first customer is not only a source of revenue.
It can also become a source of learning.
Anupam describes how his early IT services business sold an e-commerce solution even though the team did not initially know everything required to build it.
The project forced the team to learn and develop the capability needed to deliver it.
The lesson is that founders can sometimes learn faster by solving a real customer's problem than by trying to perfect everything before making the first sale.
The Core Principle Behind the Framework
Anupam Mittal's approach can be reduced to one principle
Build less. Test more.
Before investing heavily in a product, founders should try to answer a few basic questions:
Do people understand the problem?
Do they care about the solution?
Will they take action?
Will they pay?
What price will they pay?
Can the product be delivered profitably?
The faster these questions are answered, the easier it becomes to decide whether to continue, modify or abandon the idea.
Summary Takeaway
💡 Key Takeaway:
- Startup idea validation does not have to be expensive or complicated. Use WhatsApp groups, online communities, mockups, landing pages, small batches and offline experiments to test real demand. The strongest validation is not when people say they like your idea — it is when they are willing to take action and pay for it.
