Demand testing for founders

Stop building things
nobody wants.

Tell us your idea. We find the people who'd buy it, show them different ways of describing it, and tell you which one makes them act — or that none of them do.

No card. No account.

How it works

Four steps. The first one's free.

Research, positioning, campaigns and measurement — run as one pipeline so the evidence connects.

Free scan60 sec
1

Research the market

What people already search, ask and pay for — before anyone sees your idea.

  • google
  • bing
  • ad costs
  • app stores
  • reddit
  • ai answers
  • competitors
2

Shape the positioning

We draft value propositions from your market's own words. You keep what resonates; we turn those into a designed test.

  • propositions
  • dimensions
  • contrast check
3

Generate interest

We build a verified list and run the campaigns that put it in front of real buyers.

  • target lists
  • cold email
  • google ads
  • reddit
  • meta
4

Measure real demand

Varying landing pages and surveys capture what they actually do, and what they say in their own words.

Step 1 in detail

What the market scan reads.

No black box.

What we check
Google search volume

How many people type this each month — and in whose words.

What advertisers pay

High bids mean the buyer is contested. That's your market, not your idea.

Twelve-month trend

Rising, flat or dying.

The long tail

Hundreds of related queries, and which are cheap to buy.

Bing search volume

A second engine. Cheaper clicks, and a different crowd on B2B terms.

AI answer visibility in build

Whether ChatGPT and friends name your category when someone asks — increasingly where discovery starts.

Reddit and communities in build

Where the conversation happens when nobody is searching yet.

App Store and Play search in build

Store demand and review mining, for consumer apps.

Where it stops

The scan tells you whether a problem is articulated. It cannot tell you whether your solution is wanted.

Search data is a fact about your market, not your idea. Ideas with strong demand fail on framing. Ideas with none work, because the category didn't exist yet.

To know that, you have to put something in front of real people and watch. That's steps two to four.

Step 4 in detail

Not "variant 6 won". Why it won.

A winning variant is a lottery ticket. The ingredient is something you keep.

Problem named Outcome promised Why it works Emotional angle
ONE RESPONDENT SEES THREE MESSAGES PICKED UPDATES ALL FOUR ESTIMATES Every message is built from the same four ingredients, in a balanced design — so one choice is evidence about all four.
An A/B test spends each respondent on one comparison. This spends them on four — which is why a hundred people is enough, and why the answer transfers to copy you haven't written yet.

Naming wasted engineering time beat peer pressure. Stop writing the second one.

Why it holds up

Built to survive "how do you know?"

You'll make a build-or-don't call on this.

01The AI never picks the winner

It writes variants and codes replies. A statistical model over real choices decides. A tool that writes and judges is grading its own homework.

02Claims are capped at the evidence

A test that measured attention says so — not that your idea is validated.

03"Not enough evidence" is an answer

We say which part, and whether more budget would fix it.

04No leaderboard while it runs

Stopping when you like the number pushes false positives past 50%. Results unlock at fixed checkpoints.

The offer

One idea. One price. One promise.

The scan is free and always will be. This is what it costs to find out whether people respond to yours.

$499per idea

A junior dev is $8,000 a month. A wrong year costs the runway.

  • We build a 10,000-person target list, verified
  • We write the variants and run the campaign
  • ~100 real buyers, four message angles at once
  • Which message won, who responded, and their words
  • Media included, up to $400
Start with the free scan

You only pay once you've seen the scan and chosen an idea.

The guarantee

If we can't answer it, you don't pay.

Every test says whether the evidence actually resolved. If it finishes without resolving a single dimension, it's free.

We can promise that because we measure instead of guessing. A tool that always sounds confident has no way to know when it failed — so it can never offer you this.

Testing more than one idea? There's a better way to do it than buying them one at a time — we'll show you once you have your first answer.

Straight answers

How long until I get a result?

Scan is instant. A first test takes about three weeks — a new sending channel has to warm up to reach inboxes. After that it stays warm and later ideas run faster. Written replies arrive within days.

Does this tell me if my idea is good?

No — be wary of anything claiming otherwise. It tells you which description makes people act. A message can win for something nobody will pay for.

What if nobody's searching for my problem?

That's a finding — you'd be creating a category, not entering one. Ads can't reach buyers at any price, so we route to communities instead.

I don't have a list.

Good — you shouldn't use one. Each idea needs its own audience, so we build and verify a new list per test.

Can I just do the free scan and stop?

Yes, and plenty should. Worth knowing before you open an editor.

Find out now, not a year from now.

Tell us three ideas. We'll show you which one has people behind it.
