You can build it in a weekend. Can you sell it?
Anyone can ship a product now. What's rare is knowing who it's for, what they'd pay, and why they'd switch. We find out — by talking to real buyers in your market, in weeks, not quarters.

For SaaS, AI, fintech, devtools, marketplace and IT software teams, from the first customers to a new country. US and LATAM.
The most expensive thing you can build is something nobody asked for
The fastest way to lose a year: build for six months, polish for three, launch, hear nothing, and only then start asking people what they actually wanted.
Building used to be the hard part. It isn't any more. You can have something running by tonight. The hard part was always the same thing it is now: convincing someone you've never met that what you made is worth their money.
That conversation goes better when you already know what they'd say. That's the entire job we do.
Which of these is you right now?
- You're about to spend six months building on an assumption nobody outside the team has tested. Signal Check
- Customers who bought stay and pay. Outbound gets almost no replies, and only the founder can close. Go-to-Market Fit
- Deals stall and nobody can say why. Most of them aren't lost to a competitor. They're lost to doing nothing. Positioning & Win-Loss
- The price was set in a meeting. Underprice and you fill the funnel with the customers who churn hardest and ask most of support. Pricing & Packaging
- Users sign up and disappear inside 90 days, before they ever reach the moment the product makes sense. Churn & Activation
- You're entering a new country and assuming buyers there behave like the ones at home. Market Entry Check
- The deck claims a market worth billions and the source is somebody's blog post. Investor Evidence Pack

What is customer validation research?
- Customer validation research is structured evidence-gathering with the people you intend to sell to — before or alongside building — to confirm the problem is real, the buyer is who you think, and the price is one they'd actually pay. It combines qualitative interviews (why people behave as they do) with quantitative testing (how many, how much, how likely). Done properly, it replaces founder assumption with recorded, citable evidence.
Seven ways in. Fixed scope, fixed timeline.
Signal Check
Is this real, and is it real for the people you think?
- 8–12 in-depth interviews with your defined ICP, recruited and screened by us
- Senior researcher moderates every session — no junior hand-off
- Verdict memo: proceed, pivot, or park, with the evidence behind it
- Recordings and full transcripts
Go-to-Market Fit
Find the buyer, trigger, first offer and channel that repeat.
- Interviews with your best-fit customers, your lost and stalled deals, and new buyers who match your ICP, recruited by us
- Who owns, influences and signs off the purchase, and the event that made it urgent
- The entry offer that is easiest to understand and buy
- Direct sales, partners or resellers: which route to bet on, and what to stop doing
- Your buyers' own words, ready for the next outbound sequence
Positioning & Win-Loss
Find out what you're really losing to, and what to say instead.
- Win-loss interviews with buyers who chose you, chose a rival, or chose to stay on the spreadsheet
- Monadic test of 3–4 value propositions: clarity, relevance, differentiation, purchase intent
- Your real competitive alternative, named: usually “do nothing”, where a large share of qualified deals actually goes
- Which message wins, with which segment, and why
Pricing & Packaging
Find the number, the metric you charge on, and the tier, before the market decides them for you.
- Quantitative pricing study, n=150–300 in-market buyers
- Van Westendorp price sensitivity + Gabor-Granger demand curve
- Which value metric buyers accept being charged on: seats, usage, or outcome
- What a free tier, a trial, or neither does to intent at your price
- Segment cuts by company size, role, or buying stage
Churn & Activation
Hear why they left, from the people who left.
- Interviews with churned, stalled and never-activated users, recruited from your own list
- Where the first session loses them, in their words, not another read of your funnel chart
- What the ones who stayed did differently, and which of those signals is worth qualifying on
- What to fix first, ranked by how many users each one is costing you
Market Entry Check
Go, adapt or wait, per country, before you sign the entity or hire the country manager.
- Interviews with buyers and channel partners in the target country, in their language
- Local ICP, buying committee, and the incumbent you'd actually have to replace
- Price anchors in local currency, and what has to change in the offer
- US to LATAM, LATAM to US, or between LATAM countries
- Verdict memo per country, with the evidence behind it
Investor Evidence Pack
Third-party proof an investor can check.
- Market sizing built from primary data, not scraped reports
- Buyer demand evidence you can cite and attribute
- Competitive landscape and positioning gap
- Slide-ready, source-referenced

Not our first launch
GCR has run 339 studies across 33 sectors over 18 years, with 111,736 respondents interviewed. We've done concept, pricing, brand and buyer research for companies including Netflix, Spotify, Amazon, Betfair, Adidas, Coca-Cola and Abbott, and for early-stage teams with one product and one question. In technology: 8 studies, 7 of them qualitative, most recently in-depth interviews with technology customers in the US and Mexico.

Case study
What this looks like when it works
The situation
A content-subscription company was rebuilding its new tier for lower-income segments in Colombia.
The assumption
The team believed a low-cost, two-person shared subscription package would work well.
What we found
The target profile confirmed that shared subscriptions like this break down once the two people's content preferences diverge substantially.
What changed
The team restructured the low-cost tier around a single, more compelling individual subscription for the validated target.
A shared low-cost subscription only works if two people want the same content. The data showed they rarely do.
Before you book
Questions founders and GTM leads ask
What is a win-loss analysis, and what does it tell a SaaS company?
Win-loss analysis is a set of structured interviews with buyers who recently chose you, chose a competitor, or chose nobody at all. It surfaces why a deal actually moved, which is rarely the reason logged in the CRM. For SaaS teams the most common finding is that the deal was lost to inertia: the buyer kept the spreadsheet or the manual workaround, because nobody had built them an internal case for changing.
Why do SaaS users churn in the first 90 days?
Most early churn is an activation problem rather than a product problem. The user cancels because they never reached the moment the product proved its value, and the cancellation reason they type into the box is almost never the real one. Diagnosing it means interviewing the people who left, stalled or never activated: what they expected, what the first session actually gave them, and what they went back to. A funnel chart shows where they dropped. Only they can tell you why.
How do you research willingness to pay for a SaaS product?
Willingness-to-pay research puts two survey instruments in front of in-market buyers. Van Westendorp maps the range between too cheap to trust and too expensive to consider. Gabor-Granger builds a demand curve across specific price points, so revenue can be modeled instead of guessed. Both run alongside the question SaaS teams skip most often: which value metric buyers accept being charged on, whether that is seats, usage, or an outcome.
Should we launch with freemium, a free trial, or neither?
Freemium, free trial and reverse trial each filter a different buyer, and the right one depends on how fast your product proves value and what a non-paying user costs you to serve. Research settles it by testing intent at your real price under each model, with your real buyers, instead of importing a conversion benchmark from a company whose cost to serve looks nothing like yours.
How do you define an ICP that isn't just a guess?
An Ideal Customer Profile holds up when it is built from buyers who converted and buyers who didn't, not from a persona workshop. That means interviewing across both groups, isolating what the converters had in common (the trigger, who controlled the budget, the manual workaround they were already paying for in time), then testing whether those traits predict intent in a larger sample. The output is a screening rule sales and marketing can both use.
How do we build a repeatable go-to-market motion?
A repeatable go-to-market motion is one where the same buyer, the same trigger and the same pitch win again and again, without the founder in the room. Research finds it by interviewing three groups: customers who bought and stayed, deals you lost or that stalled, and new buyers who match your ICP but have never heard of you. Comparing them shows who owns the problem, which event makes it urgent, which first offer is easiest to buy, and which channel reaches them. That is what the Go-to-Market Fit study delivers.
We have happy customers but outbound gets no replies. What's wrong?
Happy customers with silent outbound usually means the product works but the targeting, the timing or the offer does not. The list may be the wrong role, the message may land before the problem hurts, or the offer may be too broad to buy in one step. Customer data alone can't tell those apart, because it only shows who said yes. Interviewing lost deals, stalled deals and cold buyers next to your best customers is what separates a list problem from a message problem from a market problem.
How do we know which buyer, problem and trigger to go after first?
The buyer, problem and trigger to go after first are the ones your best customers share and your lost deals lack. Interviews isolate them: who started the search, what happened the week before, who signed, and what they used before you. When the same pattern shows up across customers and is missing in the deals that died, that is your first segment. When it doesn't, the research says so, before you scale outbound on a guess.
We're pre-launch and pre-revenue. Is this too early for customer research?
Pre-launch is the ideal moment for customer validation research. Validation is cheapest before the build, when changing your mind costs a conversation instead of a quarter of engineering. Teams that arrive after launch usually pay twice: once for the wrong build, and once for the research that would have prevented it.
Can you reach our buyers? They're niche.
Recruiting hard-to-reach B2B audiences is standard work for us: clinicians, IT directors, procurement leads, compliance officers, specialist trades. Tell us who the buyer is and what has to be true for someone to qualify, and we'll tell you honestly, before you commit to anything, whether we can reach them and how.
Can you research buyers in the US and in Latin America?
Yes. GCR researches buyers in the US and across Latin America, and expansion between them in both directions. Our clients are based in the US and UK, and we've delivered research for Netflix, Spotify, Amazon, Betfair, Abbott and Merck. We recruit and interview US buyers in English, digitally, and run fieldwork in Spanish across Latin America from our base in Medellín, Colombia.
How do we validate demand in a new country before hiring a team there?
Demand in a new country is validated by interviewing buyers and channel partners there before you sign the local entity, apply for a license or hire a country manager. The study tests whether the local buyer, buying committee, incumbent alternative and price anchors match your home market, and what has to change if they don't. The output is a go, adapt or wait verdict per country. We run it between the US and Latin America in both directions, in English and Spanish.
Do you use synthetic panels or AI-generated respondents?
No. GCR does not use synthetic respondents, AI-generated panels or simulated buyers. AI speeds up our analysis: transcription, coding, finding patterns across hundreds of open ends. It never replaces a person. Every data point in your study comes from a real, screened human who agreed to be interviewed. A model trained on the internet can tell you what people have said before. It cannot tell you what your buyers would pay.
What do we actually receive at the end of a study?
Three things, on every package: findings tied to the decision you brought us, the raw material behind them (transcripts, data tables, recordings), and a live working session where we walk your team through what to do next. The deliverable is the decision, not the deck.
How fast can you turn this around?
Turnaround depends on the package and on how fast your specific audience can be recruited, because a niche B2B buyer takes longer to reach than a general consumer sample. You get an exact date before you commit, not after. We field in parallel where possible, and we don't take a project we can't deliver on the date we promised.
What if the research says the idea doesn't work?
Then we tell you plainly, with the evidence behind it. A clear no is the most valuable outcome we can sell you: it costs one study instead of a year of engineering, and the same interviews that produced it usually point at the adjacent problem that is worth building for instead.
