Every method on this list costs nothing but your time. They are ranked by the strength of the evidence each produces per hour spent — not by how easy they are. No start-a-business app, including Draper, changes that order. Paid tools buy time. They do not buy proof.
The order matters more than the list. The common pattern among first-time founders is to work down it backwards — starting with the method that produces the least evidence, and stopping there.
Why "free" is the wrong criterion on its own
Free is a budget, not a standard. Almost anything can be done for nothing if you spend enough hours on it, so a list ranked only by price ranks by nothing at all. This list ranks free methods by the strength of the evidence each one produces per hour you put into it.
Strong evidence has three properties. It comes from strangers rather than people who know you. It asks for something that costs the other person a little — attention, an email address after they have seen a price, a place in a queue. And it can come back negative.
That last one does most of the work. A method that cannot produce a no is not a test. It is a way of feeling better about a decision you have already made.
How do the free validation methods rank?
The strongest free methods are breaking an idea into its assumptions, putting a real promise on a page in front of strangers, and trying to sell before you build. The weakest is asking people who know you. Interviews, public complaints and competitor pricing sit in between as support for the top three.
| Rank | Free validation method | What it costs you | Strength of the evidence |
|---|---|---|---|
| 1 | Break the idea into assumptions and check them | A few afternoons | Strong — finds the risk before you spend on it |
| 2 | Put up a landing page and send strangers to it | A day to build, then the work of getting traffic | Strong — the only method that scales for nothing |
| 3 | Try to sell it before it exists | Hours of outreach, plus your nerve | Strongest per person — a stranger's yes settles it |
| 4 | Interview strangers who already pay to solve the problem | Hours of finding people, then listening | Strong, if they are strangers |
| 5 | Read what the market already complains about in public | An evening of reading | Moderate — unfiltered, but unrepresentative |
| 6 | Study what competitors already charge for | An hour or two | Moderate — proves a market, not your angle |
| 7 | Ask friends and family | Twenty minutes | None — it cannot produce a no |
1. Break the idea into assumptions and check them one at a time
Breaking the idea into the assumptions it depends on, then checking them one at a time, is the strongest thing you can do for nothing. Every idea rests on a handful of things that must all be true. Written down, most can be checked in an afternoon, and the weakest one tells you where the risk actually sits.
Write the list plainly. This group of people exists in enough numbers. They already spend money on this problem. They can be reached without a budget I do not have. The thing I am planning to build actually solves it. I can deliver it at a price they will pay.
Then rank them by how badly the idea breaks if one turns out to be false, and start with the worst. Most of them are answerable with an hour of searching, a few phone calls, or a look at what already exists.
This is the method that stops you building. That is its value.
2. Put up a landing page and send strangers to it
A landing page is one of the strongest free tests available. A one-page site carrying a specific promise and a price costs nothing but a day to build, and the traffic can be free as well — posting where your buyers already gather, answering the questions they are already asking, or using an audience you have. Paid ads buy speed and precision, not the result.
This is the method I use most, because it is the only one on the list that scales without a budget. One page can be seen by a hundred strangers in a week.
Our guide on how to build a website to test a business idea covers the page itself — the single promise, the price, the one action, and how to instrument it so a no is unambiguous.
The honest caveat with organic traffic is that you are testing your reach alongside your idea. A great promise shown to twelve people proves little either way.
3. Try to sell it before it exists
Attempting to sell the thing before you build it is the strongest signal any single person can give you. A stranger agreeing to pay, or asking when they can, settles a question nothing else on this list can settle. It also fails fast, which is the point — a no here costs you an afternoon rather than six months.
You do not need a product. You need a specific promise, a price, and someone who has the problem. A conversation, a message, a short call.
Skipping this feels like the sensible thing to do, on the grounds that it is premature. It is the opposite. Selling first is how you find out whether the price you had in mind is a real price or a hopeful one.
It sits below the landing page only because it does not scale. Each yes costs you an hour, where a page can collect a hundred answers while you sleep.
4. Interview strangers who already pay to solve the problem
Interviews are free and produce strong evidence, provided the people are strangers who are already spending money on this problem some other way. Someone paying for a bad solution has proved the problem is worth money to them. Someone who merely agrees it sounds annoying has proved nothing.
The hard part is not the interview. It is finding the right people and resisting the urge to pitch. You are there to hear how they describe the problem, in their words, and what they currently do about it.
Ask what they tried, what it cost, and why they stopped. Do not describe your solution until the end, if at all.
Ten of these will teach you more about your positioning than any amount of desk research, and they cost nothing but the hours.
5. Read what the market already complains about in public
Public forums, review sites and community threads are free, unfiltered and specific. People describe problems there in the language they actually use, without a founder in the room shaping the answer. That language is worth more than the conclusions — it becomes the copy on your page.
Treat the conclusions carefully. The people who post are not a representative sample of the people who buy, and a loud thread is not a market.
Use it for two jobs. First, to find the words. Second, to find the complaints that recur across different places and different years, which is a better signal than one busy thread.
What it cannot tell you is whether anyone will pay. Reading is the cheapest step and the furthest from a transaction.
6. Study what competitors already charge for
Looking at what existing companies already sell, and at what price, is a free hour that answers one specific question: does money change hands in this market at all. A crowded market is evidence that it does. An empty one is more often a warning than an opening.
This is the step people misread. Finding competitors feels like bad news and is usually the opposite — it means somebody has already proved the demand you were worried about.
What it does not prove is your angle. Competitors validate the market; they say nothing about whether your particular version is better or differently positioned.
Read their pricing pages, their review sections and what customers complain about. The gap you are looking for is usually written in the one-star reviews of the incumbent.
7. Ask friends and family — free, and not validation
Asking friends does not count as validating a business idea. Friends and family will support your idea, which is the opposite of what a test is for. They are answering a question about your relationship, not about the market. A method that cannot produce a no is not a test.
I have made this mistake myself. I have plenty of business ideas, and I have rushed into building before checking any of them. Talking to friends, mistaking that for comprehensive validation, and then being surprised that the market was not ready for the product.
The encouragement is real. It is simply evidence of something else.
There is one narrow use. Friends are good for rehearsing how you explain the idea — where they get confused is where a stranger will too. Use them to sharpen the sentence, never to decide.
When is it worth paying, if all of this is free?
Pay when the free version of a step is eating weeks you do not have. Every method here costs hours, and hours are the one input a person with a job cannot add to. A start-a-business app is cheap against that: Draper runs the whole sequence — research, brand, product, site and live ads — so your week goes on the decision rather than the setup.
Cheap is not free, and it is not proof. Draper's ads buy speed and precision, not the result — a click on one is not a stranger's yes.
What it changes is where the week goes. Ranks one and two are where founders lose the most time — the assumption list and the page — and both are largely preparation rather than judgement.
If you want to speed up the paid half of the page test, our guide on how to run ads to test a business idea covers targeting a defined customer and reading the result honestly.
How do you apply this list to your own idea?
Start at rank one and work down, not up. Write out the assumptions, pick the one that breaks the idea worst if it is false, and check that first. Then get a page up and put it in front of strangers. Everything below rank three is support for the top three, not a substitute for them.
Give yourself a fixed window — a week is enough for the first three ranks — and decide in advance what result would make you stop.
The failure mode this list is designed to prevent is the common one. Talk to a few supportive people, feel encouraged, build for six months, then discover the market was never ready.
The cheapest week you will ever spend is the one that stops you.
