Hard questions from 100 customers, before you build.
Paste your idea. ducira finds the 100 people most likely to buy, lets them ask everything they’d ask you, then breaks your answers — until one real problem and one first customer are left.
No card. You get 700 credits when you sign up. One full run costs about 610. Powered by NVIDIA Nemotron-Personas (CC BY 4.0).

HOW IT WORKS · FIRST CUSTOMER
Seven steps. You answer between them; the corpus does the rest.
Every number on screen is counted from individual personas — never estimated by a model. Verdicts on your own answers stay yours: ducira never grades its own rebuttals.

Every customer question
100 people who actually have your problem ask what they would ask you. You see how many of the 100 asked each one.

Hard questions
Your best answer to each question, then the question that breaks it.

Real problems
Only what you couldn’t refute goes in. We name the problem underneath, then ask the group who has it — and who would pay.

Your system
The solving process written as a repeatable system: steps, roles, tools, metrics — and the number that tells you to stop.

Sales questions
What to ask before you explain your system to a real customer — tried on 30 personas first so only the openers survive.

THE CORPUS
One million US personas, each with a household, a job and a Tuesday night.
Built on NVIDIA’s Nemotron-Personas-USA. ducira picks the 100 whose lives match your idea and locks that sample for the whole run, so step 7 asks the same people step 2 did.

ClosesExample personas for “meal-prep for night-shift nurses” — synthetic, not real people. Good at direction, weak at exact prices.
WHAT IT IS, AND WHAT IT IS NOT
Synthetic, not real.
The 100 customers are AI personas built on US Census distributions (NVIDIA Nemotron-Personas-USA). They are good at showing the direction of a concept or a preference. They are weak at brand awareness and exact price points, and they are not a substitute for talking to real people.
Counted, not guessed.
Every number you see is a count of individual persona responses (“37 of 100 asked about price”). We never turn that into a market-size prediction.
You decide.
Only the hard questions you mark as “can’t refute” become problems. The AI never grades its own arguments.

FAQ
- Is this a survey tool?
- No. Surveys ask people to rate your idea. These steps make 100 people ask you questions, then make your answers fail — that is where the real problem hides.
- How long does a run take?
- About 20 minutes of AI time across the seven steps, plus however long you spend deciding between them. Most founders finish in an evening.
- What do I get at the end?
- A First customer report: one person from the corpus, the problem they have, what they do about it now, whether they would pay, and the questions to open a real conversation this week.
