Imagine you have a business idea. It has been living in your head for weeks. You tell your friends, they say “that’s nice,” and you feel great for about an hour. Then the doubt creeps back. Is this actually a good idea, or just a good story you tell yourself?
Here is the uncomfortable truth: nobody can tell you, not your friends, not an expert, and not an article like this one. Only strangers who are willing to give you their time or their money can. The good news is that you can find out what they think in seven days, without writing a line of code or spending a big amount.
Validation sounds like a fancy startup word, so let’s make it simple. To validate an idea means to check, before you build it, whether real people have the problem and care enough to act. That is all. Think of it like tasting a spoonful of dal before you cook the whole pot for the wedding.
First, what does “proof” even look like?
Most beginners collect the wrong kind of proof. “Great idea!” feels like proof, but it costs the speaker nothing to say it. Your cousin will say it. Your college friend will say it. Politeness is free.
A better way to think about proof is as a ladder with three steps. The lowest step is words: compliments and opinions. The middle step is time: someone agrees to a 20-minute call, answers your questions in detail, or introduces you to a colleague. The top step is money: someone pays, pre-orders, or signs a letter saying they will buy. Each step up costs the other person more, so each step tells you more.
Your goal this week is to climb as high as you can on that ladder, as fast as you can.
Day 1: Write down your idea as a sentence a child could repeat
Start with one page and one sentence. Use this format: “I help [specific people] solve [specific problem] by [simple solution].”
Here is a hypothetical example, made up for this article. “I help working parents in Pune get home-cooked lunch delivered to their office desk, so they stop ordering oily takeaway on busy days.” Notice how specific it is. “People who want healthy food” is not a customer. “Working parents in Pune who skip lunch” is.
Then write down the three beliefs that must be true for your idea to work. Maybe parents really do skip lunch. Maybe they would pay more than their usual canteen price. Maybe a delivery cost of that size is possible. These beliefs are your assumptions. Your week is about testing the scariest one first.
Day 2: Find ten real people, not ten friends
Now go and find ten people who match your sentence. Not your mom and not your best friend. Try the place where these people already hang out. If your idea is for small shop owners, visit three shops near you. If it is for freelancers, look at a WhatsApp group, a Reddit community, a LinkedIn search, or a local coworking space.
Send a short, honest message. Something like: “Hi, I’m researching how working parents handle lunch at the office. Could I ask you five quick questions? It will take 15 minutes and I’m not selling anything.” People are surprisingly generous when you are clear that you are listening, not pitching.
If ten feels like a lot, aim to message thirty. Maybe only ten will reply, and that is normal.
Day 3 and 4: Talk to them, and mostly listen
This is the heart of the week. Your job in these conversations is to learn about their life, not to pitch your idea. Ask about the last time the problem happened. What did they do? What did it cost them in money, time, or stress? What have they already tried, and why did it fall short?
There is a famous short book on this called The Mom Test by Rob Fitzpatrick. Its three rules are easy to remember: talk about their life instead of your idea, ask about specifics in the past instead of opinions about the future, and talk less and listen more. We go deeper into this in our guide to validating your idea for Rs 0.
Take notes during each call. After each one, write down a single line: “What did I learn that surprised me?” If nothing surprised you, you probably asked leading questions.
By the end of day 4, patterns will show up. Maybe seven out of ten people mention the same annoying step. That repeated pain is gold. If every person describes a different problem, or says the problem is not that bad, that is useful too. You just saved yourself six months.
Day 5: Offer something small and watch what people do
Words are cheap. Now ask for a small action. This is the step most people skip because it feels awkward, but it is where the truth lives.
You do not need a finished product. You can offer a simple page describing the idea with a button that says “Reserve your spot.” You can offer to do the job by hand for three people. You can ask for a small advance, even Rs 100 or Rs 200, to hold a place on the waiting list. The point is to see who steps forward when something real is on the table.
Two real stories show how small these tests can be. Joel Gascoigne, the founder of Buffer, tested his idea with a simple two-page site: one page explained the product, and a second showed pricing plans before asking for an email. When people clicked through and a few chose paid plans, he went ahead and built it. He had his first paying customer within four days of launching the rough first version.
Drew Houston, who started Dropbox, took a different route. Before the product was polished, he released a short demo video. According to a TechCrunch interview, a later video aimed at the Digg audience brought 75,000 sign-ups to the waiting list within 24 hours, when the team had expected 15,000 at most. Neither founder asked friends if the idea was nice. They showed it to strangers and counted who raised a hand.
Day 6: Count what happened, honestly
Sit down with your notes and a cup of tea. Count three things. How many people did you talk to? How many described the problem without being prompted? How many took a real action, such as agreeing to a follow-up, joining the waiting list, or paying?
Be strict with yourself. “He said he might buy” is a word, not an action. “She asked when it would be ready” is a good sign, but “she gave me Rs 200 to reserve it” is a much stronger one.
A simple scoring method helps. Give yourself one point for each person who described the problem in detail, two points for each who agreed to another call or a trial, and five points for each who paid or pre-ordered. There is no magic number, but if you spoke to ten people and the total is close to zero, listen to that.
Day 7: Decide, and make the decision small
You now have three honest options. First, go: people have the problem, several acted, so build the smallest version for the people who stepped forward. Second, change: the problem is real, but your solution or customer was off, so adjust and test again next week. Third, stop: nobody cared. That is not failure. You spent seven days instead of seven months.
Whichever you pick, write down one next step for the next seven days. Keep it small enough that you could finish it. If your result is a “change,” our post on when to pivot will help you think through what to adjust.

Common mistakes that waste your week
The first mistake is talking to people who love you. They want you to be happy, so they will protect your feelings. The second is pitching too early. If you start with “I’m building an app that…,” people switch to review mode and give you opinions. The third is falling in love with your solution. Stay curious about the problem and let the solution change.
The last one is asking for no action. If a week passes and nobody has been asked for time or money, you have collected opinions, not evidence.
Key takeaways
- Validation means checking, before you build, whether real people have the problem and care enough to act.
- Proof climbs a ladder: words are weakest, time is stronger, money is strongest.
- Talk to ten strangers who match your target customer, and ask about their past, not your idea.
- Ask for a small real action by day 5, such as a sign-up, a trial, or a small advance.
- Decide on day 7: go, change, or stop. All three are good outcomes if they are honest.
The best founders are not the ones with the best ideas. They are the ones who find out fastest which ideas are wrong. If you want an easy place to practise, pick one idea from our list of business ideas born from everyday problems and run this week on it.
