Market Research With an AI Agent: Validate a Business Idea in One Day With 8 Prompts
How to do market research with AI in 2026 and validate a business idea in a day: eight prompts that size the market, map the competitors, test the price and demand, and write the one-page case from free UK data (ONS, Companies House, Google Trends, HMRC), what an agency report costs, and the survival numbers that make the day worth it.
Every business idea sounds good at 11 pm. The ONS counted 317,000 business births in the UK in 2024 and 280,000 deaths, and only 38.4% of the businesses born in 2019 were still trading five years later. The old CB Insights post-mortem study found that 42% of failed start-ups cited "no market need", which is a polite way of saying nobody checked. Checking used to mean an agency: Brandspeak's published 2026 guide puts a small qualitative study at £5,000 to £15,000 and a quantitative survey at £10,000 upwards, which is why most people skip it and find out the expensive way.
Market research with an AI agent costs a day and nothing else. Done properly, market research with AI is not a chatbot's opinion about your idea: it is reading, counting and testing. The agent reads the free data the UK publishes (the ONS, Companies House, HMRC's VAT statistics, Google Trends), finds and sizes the competitors, drafts and runs a survey, tests the price, and writes the one-page case with the numbers you would need to show a bank or a partner. This guide is the day, hour by hour, with the eight prompts in the order they build on each other, the free sources behind them, and the honest line about what the agent cannot know.

What a day of research has to answer
- Is there demand, and how much? Search volume, trends, and how many people or businesses in your area fit the customer.
- Who already serves it? The competitors, what they charge, what their reviews complain about.
- Will people pay your price? Tested with real people, not assumed.
- What does it cost to start and to run? The first-year numbers, with the tax and registration basics.
- What would make it fail? The three risks, named, with the evidence.
If the day answers those five, you can decide. The agent does the reading and the arithmetic; you do the deciding.
The 8 prompts, in order
| Prompt | Hour | What the agent does | Free source it uses | What you get |
|---|---|---|---|---|
| 1. Define the customer and the market | 9 am | Turns the idea into a customer, a problem and a place | ONS Census 2021 and Nomis for population and income | A one-paragraph definition and the size of the local or national market |
| 2. Demand check | 10 am | Reads search interest and trend over five years | Google Trends, Google Keyword Planner | A demand curve, seasonality, the terms people use |
| 3. Competitor map | 11 am | Finds every competitor within reach and what they charge | Companies House, Google Maps, their own websites | A table of competitors, prices, years trading, review themes |
| 4. Review mining | 12 pm | Reads hundreds of competitor reviews for the gaps | Google and Trustpilot reviews | The five complaints nobody fixes |
| 5. Price test | 2 pm | Drafts and runs a short survey or landing page test | Google Forms or SurveyMonkey's free plan, a one-page site | A price range and a sign-up rate |
| 6. Start-up and running costs | 3 pm | Builds the first-year budget | HMRC, GOV.UK, supplier prices | Monthly costs, break-even, the registration steps |
| 7. The three risks | 4 pm | Argues against the idea with the data | Everything above, ONS survival rates | The three ways it fails and what would reduce each |
| 8. The one-page case | 5 pm | Writes the summary a bank or partner would read | Everything above | A page with the numbers and the decision |
1. Define the customer and the market
Vague ideas produce vague research. The first prompt forces the definition, then sizes it with the Census and Nomis, both free from the ONS, which give population, age, income and employment by local area.
Message to send
My business idea in one sentence: a mobile dog grooming service for the Harrogate and Knaresborough area. Define the customer (who, what problem, how they solve it today), then size the market using free ONS data: households in the area, the share likely to own a dog using the best published UK estimate with its source, and the realistic share a one-van service could serve. Show every figure with where it came from and flag anything you had to estimate.

2. Demand check
Google Trends is free and shows five years of interest for any term by region; Keyword Planner shows monthly searches once a Google Ads account is set up. The agent pulls both, reads the seasonality, and tells you whether demand is rising, flat or a fad.
Message to send
Check demand for this idea. Use Google Trends for the last five years in the UK and in Yorkshire for the terms people would search, list the ten most relevant search terms with their monthly UK volume where you can find it, show the seasonality, and tell me plainly whether interest is growing, flat or falling, with the chart.

3. Competitor map
Companies House search is free and shows when each competitor was incorporated and whether it is still filing; the agent cross-references with Google Maps and the competitors' own pages for prices.
Message to send
Map the competitors for this idea within 15 miles. For each one: trading name, years trading (check Companies House where it is a company), prices from their website, Google rating and review count, and what they offer that I would not. Put it in a table and tell me where the gap is: price, area, hours, or a service nobody offers.

4. Review mining
The most useful research in the day costs nothing: hundreds of competitor reviews, read for what customers complain about. "Never turns up on time", "cannot get through on the phone", "no evening slots". The agent reads them and counts.
5. Price test
Two free routes. A short survey (Google Forms is free; SurveyMonkey's free plan allows up to ten questions per survey) sent to 30 people who fit the customer definition, asking what they pay now and what they would pay. Or a one-page site with the offer and a price, built by the agent and hosted on Jobbit, with a "book a slot" button that measures real intent. Twenty sign-ups from a £50 Facebook post is worth more than a hundred survey answers.
Message to send
Build a one-page site for this idea to test demand: the offer, three price options (£35, £45 and £55 for a standard groom), a "Book your first slot" form that takes name, postcode and preferred price option, and a thank-you message. Make it look like a real local business, mobile first. Then write a 60-word Facebook post for local groups that sends people to it, and tell me how to read the results after seven days.
You create a free account first (an email address is all it takes, no card). Your message is kept and sent the moment you are in.
6. Start-up and running costs
The agent builds the first-year budget from supplier prices you give it and the public rules: registering as a sole trader when trading income passes the £1,000 allowance, Self Assessment by 5 October after the first tax year, VAT registration at the threshold, and the Start Up Loans scheme (GOV.UK: £500 to £25,000 at a fixed 7.5% a year, with up to 12 months of free mentoring, for businesses trading under five years).
7. The three risks
Ask the agent to argue against you. It uses everything above plus the survival statistics and names the three most likely reasons the business fails, with what would reduce each one. This is the hour most people skip and the one that saves the money.
Message to send
Now argue against this idea. Using everything you have found today and the ONS five-year survival rate of 38.4% for businesses born in 2019, give me the three most likely reasons this business fails in its first two years, with the evidence for each, and what I could do before launch to reduce each risk. Be blunt.

8. The one-page case
Market size, demand trend, competitors and the gap, the price people chose, the first-year budget, the three risks, and a recommendation: go, go with changes, or stop. One page, with the sources listed, in the format a bank or a Start Up Loans adviser expects.
What the agent cannot know
An AI agent reads what is published and what you give it. It cannot know what your neighbours will actually buy, which is why prompt 5 puts a real offer in front of real people, and it will present an estimate with the same confidence as a fact unless you ask it to flag estimates, which every prompt above does. Check the three numbers that decide the case (market size, price, monthly costs) against the source it names before you borrow money on them.
How an AI agent differs from asking ChatGPT
ChatGPT, Claude, Gemini, Microsoft Copilot, Manus and Meta's Muse will all brainstorm a business idea and summarise a market. Jobbit adds the parts that turn a summary into evidence:
- It browses and reads the ONS tables, Companies House, Google Trends and hundreds of reviews, with the sources kept.
- It builds the test: the one-page site with the booking form, hosted, so you measure intent instead of opinions.
- It does the arithmetic on market size, break-even and the first-year budget in a spreadsheet it keeps.
- It keeps the project: every finding, chart and source in one place, so the business plan is a sentence away.
- It hands off to people from the network when you want twenty customer interviews done by a researcher.

Frequently asked questions
Can AI do market research?
Yes, for the research most small businesses need: sizing the market from ONS data, mapping competitors through Companies House and their own pages, reading reviews for gaps, running a survey or a landing page test, and building the first-year budget. An agent on Jobbit does it in a day with the sources listed, on a free plan.
How do I validate a business idea for free?
Define the customer, check demand on Google Trends, map the competitors, read their reviews, then put a real offer with a price in front of real people through a one-page site or a short survey. The eight prompts in this guide do that in order, using free UK data, in one day.
What free data can I use for UK market research?
The ONS (Census 2021 and Nomis for population, income and employment by area), Companies House search for every competitor's age and filings, Google Trends and Keyword Planner for demand, HMRC's VAT statistics for the number of businesses by sector, and Google and Trustpilot reviews for what customers complain about.
How much does market research cost?
A commissioned study from an agency runs from about £5,000 for a small qualitative project to £10,000 and more for a survey, according to published agency guides. The day in this guide costs nothing on the free plan, plus whatever you spend on a test advert.
How many businesses survive in the UK?
The ONS business demography release for 2024 puts the five-year survival rate for businesses born in 2019 at 38.4%, with 317,000 births and 280,000 deaths in 2024. Research before launch does not change the odds for everyone, but it changes them for you.
Is AI market research accurate?
As accurate as its sources and its honesty about estimates. Ask the agent to show where every figure came from and to flag anything it estimated, check the three numbers that decide the case against the source, and test the price with real people rather than relying on a survey of friends.
What is the best AI for market research?
One that can browse, read the data tables, build the test page and keep the sources, rather than only summarise. The assistants draft well; an agent on Jobbit reads, builds, measures and writes the one-page case from the same chat.
