Centiment vs Pollfish: Survey Panels Compared (2026)
Matthieu Saussaye
Centiment and Pollfish both sell you respondents. Neither one tells you what those respondents meant.
If you are comparing Centiment vs Pollfish for survey panels, you are probably trying to buy a sample: a few hundred people who match your target, at a price that fits the budget. Both do that well, in very different ways. But the sample is only half of a study. The questionnaire, the open answers and the analysis are where most projects stall, and that is where SmartInterview pulls ahead of both.
The Short Answer
SmartInterview: the best choice for most teams. The AI drafts the questionnaire, recruits respondents in Switzerland and Europe or uses your own customers, asks follow-up questions when an answer is vague, and hands back coded themes, sentiment and cross-tabs, usually in about 48 hours.
Pollfish: the cheapest way to reach a very large global consumer audience, from $0.95 per response, through people invited inside mobile apps.
Centiment: a managed panel with a human research team, fraud scoring on every respondent, and per-response pricing from $1 that works with your existing survey tool.
Pick Pollfish for reach, Centiment for a managed panel, and SmartInterview when you need the why behind the numbers, not just the numbers.

How Each Panel Finds Its Respondents
The biggest difference between Centiment and Pollfish is not the price. It is where the people come from, and that shapes data quality more than any feature. If panels are new to you, start with what panel research is.
Pollfish: Random Device Engagement
Pollfish does not run a classic panel. It shows surveys inside mobile apps and websites that people are already using, and rewards them inside that app. The upside is reach: more than 250 million consumers in over 160 countries, and fresh respondents who are not professional survey takers. The trade-off is that respondents are not profiled panel members, so precise targeting costs extra screening questions, and attention can be short on a phone.
Centiment: a managed opt-in panel
Centiment works more like a traditional panel provider with a service layer. Respondents come from its own panel and partners, and each one carries a fraud score built from IP checks, proxy detection, duplicate prevention and human review of low-quality answers. You can program the survey in your own tool and Centiment charges the same per response. Reviewers on G2 rate it 4.9 out of 5 (132 reviews) against 4.5 for Pollfish (48 reviews) at the time of writing, mostly for the support.
SmartInterview: panel and your own customers, in one study
SmartInterview recruits an audience in Switzerland and Europe and, in the same study, gives you a reusable link for your own customer list. Every response is tagged by source, so you can read customers and non-customers separately or together. Then the part neither panel does: the AI probes thin answers while the respondent is still there. On sampling and bias, the same rules apply everywhere; the difference is what you get back from each respondent.
Feature by Feature: Why SmartInterview Comes Out Ahead
Centiment and Pollfish are sample providers with a survey tool attached. SmartInterview is a research platform with the sample built in. Here is what that changes, step by step.
1. Questionnaire design
Pollfish offers a free AI survey builder and Centiment lets you bring Qualtrics or another tool, but in both cases you are responsible for the questionnaire. SmartInterview starts from your objective, drafts the full questionnaire with closed questions, scales, open questions, quotas and logic, and gives it a quality score before launch. Our survey questions guide explains the rules it checks.
2. Respondents and sample
Pollfish wins on raw global reach and Centiment on managed targeting. SmartInterview wins on the mix that most brands actually need: a recruited audience plus your own customers in one instrument, tagged by source, with screen-outs and quotas enforced live.
3. Open answers
This is the decisive difference. On Pollfish and Centiment, an open question is a text box: whatever the respondent types is what you get, often three words on a phone. SmartInterview asks a follow-up when an answer is vague, and respondents can answer by voice. In our studies, that delivers up to 4x longer answers and 2.2x more topics per respondent. More on why in open-ended questions and voice surveys vs traditional surveys.
4. Analysis
Pollfish gives you a dashboard, and presentation-ready reports only with its full service, from $5k per market. Centiment gives you real-time results and an export. SmartInterview codes every open answer into themes linked to the verbatims, with sentiment and cross-tabs, and exports to Excel or SPSS. That is the step that usually takes an analyst days; see how it compares in our survey analysis tools review.
5. Price and speed
Per response, Pollfish is the cheapest entry point and Centiment is close behind. But a cheap sample with uncoded open answers is not a cheap study: the analysis time comes later. SmartInterview starts free for the first 50 respondents, with plans from CHF 45 per month, and typically returns results in about 48 hours. Details on the pricing page.
When Pollfish or Centiment Is Still the Right Call
You need many countries outside Europe in one wave. Pollfish reaches 160+ countries.
You already have a programmed Qualtrics survey and only need sample. Centiment plugs in at the same price per response.
You want a human team to manage the panel for you. That is Centiment's whole model.
Where I draw the line
I use a panel provider when the only question is "how many": a quick pulse, a price-point check, a yes or no across many markets. The moment the decision depends on why people choose, hesitate or leave, I do not buy more sample, I change the instrument. Three extra words in a text box will not change a positioning; a follow-up question that turns "too expensive" into "too expensive for something I only use in summer" will.
What goes wrong is buying the cheapest completes, skipping the open questions to save money, and then trying to explain the numbers in a meeting with no verbatims to back them. The panel was fine. The study was not.

A Real Example: Four Concepts, One Decision
Pharmalp, a Swiss natural health brand, wanted to launch four new supplement concepts and needed to know which one to back, and at what price. A classic panel study would have returned preference shares and a price curve. With SmartInterview, respondents explained their choice by text or voice, the AI probed the vague answers, and the analysis grouped the reasons into themes per concept. The team could see not only which concept won, but which claim made people hesitate. Read the Pharmalp case study.
How to Choose in Five Minutes
Write down the decision. If it is a number (share, price, awareness), any of the three works. If it is a reason, you need probing.
List your markets. Many countries outside Europe point to Pollfish; Switzerland and Europe point to SmartInterview.
Check who writes the questionnaire. No researcher on the team? Let the AI draft it and score it.
Count the open questions. More than two, and manual coding will cost more than the sample.
Run one real study. The first 50 respondents on SmartInterview are free.

Frequently Asked Questions
Is Centiment better than Pollfish?
It depends on the job. Centiment is better if you want a managed panel with human support and fraud scoring; Pollfish is better for cheap, fast reach across many countries. If you also need the questionnaire written and the open answers analysed, SmartInterview does more than either.
How much does Pollfish cost per response?
Pollfish starts at $0.95 per response on its self-serve platform, with extra fees for screening questions, quotas and advanced targeting. Full-service studies start at $5k per market.
How much does Centiment cost?
Centiment prices per completed response, from about $1 for broad audiences, with harder-to-reach audiences such as IT decision makers costing several times more. Pricing is quote-based and the same whichever survey tool you use.
Does Pollfish use a survey panel?
Not in the classic sense. Pollfish uses Random Device Engagement: people are invited to answer inside mobile apps and websites they already use, and are rewarded in that app, rather than being recruited into a standing panel.
What is the best alternative to Centiment and Pollfish?
SmartInterview is the best alternative when the study needs more than a sample: it drafts the questionnaire, recruits respondents in Switzerland and Europe or uses your customer list, asks AI follow-up questions and codes the open answers automatically.
Can I use my own customers and a panel in the same study?
Yes on SmartInterview: the panel and a reusable link for your customer list run in the same survey, and every response is tagged by source so you can compare customers and non-customers.
How fast can I get results?
A panel study on any of the three can field in days. SmartInterview typically returns analysed results, with themes and cross-tabs, in about 48 hours.
