Customer Satisfaction Research Companies in the US 2026

Last updated: 23 September 2026

Quick Answer: Customer satisfaction research companies that run interviews include Alchemic, Advanis, Amplitude Research, Bellomy, BestMark, C Space, Confero, Conifer Research, Forsta and Ipsos. They split into phone and CATI houses, CX program firms, mystery shopping firms and qualitative consultancies. Choose by who must be reached and whether you need a benchmark score or the reason behind it.

The American Customer Satisfaction Index says on its methodology pages, read on 23 September 2026, that it conducts more than 200,000 interviews a year and recruits those respondents by surveying customers at random via email. Each completed questionnaire about a company is coded as a customer interview for that company.

That usage is standard, and it is the first thing to check on any shortlist. In satisfaction research, "interview" can mean a person who talked for twenty minutes or a person who answered three rating questions in an inbox, and the two produce different evidence. A score tells you where satisfaction moved. Only a conversation tells you why.

Key Takeaways

• Ask what the respondent actually does. Many firms say "interviews" and mean scaled questionnaires; a few run conversations that probe the answer.
• Four kinds of company serve this work: phone and CATI houses, CX program firms, mystery shopping firms, and qualitative or AI-native interview services.
• Mode changes the score. In a randomized hospital-survey experiment, telephone and active IVR respondents rated care more positively than mail respondents, with some effects worth more than 30 percentile points in hospital rankings.
• One channel hears one slice. In a 2024 randomized trial, a three-mode protocol lifted response to 36.5%, against 22% to 24% for single-mode designs.
• Keep research and service recovery apart. Calling an unhappy customer to win them back fits the Insights Association Code's definition of a non-research activity.

How This Guide Evaluates Customer Satisfaction Research Companies

Each company was read on its own website on 23 September 2026, not through a directory. No company was briefed or paid, and no price appears unless the company publishes one. The list started from the companies an assistant surfaced for this query, minus a B2B expert network and a polling firm with no published satisfaction offer.

Five criteria decided inclusion and shaped each entry:

1. Conversation, not only a questionnaire. Does the company follow up on an answer, or only administer rating scales?
2. Published modes. Phone, IVR, SMS, web, WhatsApp, in person or online community.
3. Who owns the sample. Your customer list, the company's panel, or both.
4. What comes back. A score, a driver model, verbatims, a benchmark or a recommendation.
5. Service model. Full service, platform with consultants, or fieldwork only.

The numbered list puts the host company first, Alchemic, and the other nine alphabetically. The table below uses strict alphabetical order.

Customer Satisfaction Research Companies at a Glance

Sorted alphabetically by company name, from each company's own pages on 23 September 2026.

Following Up by Phone

To hear from customers who left or scored you low, the AI phone research service shows how Alchemic calls a list, captures consent on the first turn and codes themes while calls complete.

Which Companies Run Customer Satisfaction Interviews Rather Than Surveys

Ten companies, each described by what it sells, where it is strongest, and one concrete limit.

1. Alchemic: Best for Following Up Detractors and Lapsed Customers at Scale

Alchemic runs AI-moderated interviews on the channel the respondent picks: a web link, a WhatsApp conversation with no link and no app, or an outbound AI phone call. The moderator is trained per study on the category and the brand's vocabulary, probes each rating, and codes themes while fieldwork is open.

• Strengths: Recruitment is managed fieldwork or bring your own, so a CRM export of detractors, churned users or support cohorts can be interviewed directly, with a panel top-up if needed. Studies have run across 14 markets including the USA and the UK, and the service publishes 57+ languages including Hindi, Tamil and Telugu. A 200-interview qualitative study runs brief to live dashboard in 3 days.
• Limitations: No normative satisfaction database to benchmark a score against industry peers, and no mystery shopping.
• Best for: End-to-end consumer research at scale when the question is why the score moved.

2. Advanis: Best for Phone Studies That Need High Response

Advanis is a Canadian full-service research firm serving businesses, not-for-profits and government, with roughly 60 public sector organizations as clients across Canada. It runs CATI in English, French, Arabic, Spanish, Mandarin and Hindi, and blends CATI with IVR and online recruitment.

• Strengths: Blended inbound and outbound calling for hard-to-reach groups such as shift workers, and CATI recruit-to-online for populations a panel cannot find.
• Limitations: Customer satisfaction is one application among many rather than the firm's specialty, and its public case work leans toward Canadian public research.
• Best for: A satisfaction study where the response rate and the phone itself are the point.

3. Amplitude Research: Best for B2B Client Satisfaction

Amplitude Research, based in Boca Raton, Florida, specializes in the design, administration and reporting of customer and client satisfaction surveys. It runs online, mail and telephone surveys plus executive interviewing, and about 30% of its customer surveys involve telephone interviewing.

• Strengths: A question library of more than 1,500 satisfaction items, a statistician or PhD on full-service projects, and key-driver work linking satisfaction to loyalty.
• Limitations: The published offer centers on structured surveys; executive interviewing is the conversational option.
• Best for: Key-account and B2B satisfaction programs that need a defensible driver analysis.

4. Bellomy: Best for Always-On CX Programs Across Touchpoints

Bellomy describes itself as an analytics and tech-driven insights agency working with Fortune 1000 companies across more than 20 industries; utility, consumer goods and financial services clients lead its testimonials. Its CX program invites customers by phone, IVR, email, QR code and digital intercept.

• Strengths: An orchestration engine that respects Do Not Contact status, hierarchical dashboards, and quarterly insight reports.
• Limitations: Built for continuous measurement across journeys, which is more program than a one-off diagnostic study needs.
• Best for: A utility, retailer or financial brand that wants satisfaction measured at brand, journey and transaction level at once.

5. BestMark: Best for Pairing Satisfaction With Mystery Shops

BestMark has worked on customer experience since 1986 and is best known for mystery shopping. Its satisfaction programs reach customers by web, SMS or phone and IVR, through receipt links, QR cards and opt-in texts, with results in its BestMetrix platform.

• Strengths: The same partner can compare what customers say with what a trained shopper observed, and an API sends CSAT surveys automatically.
• Limitations: Satisfaction work is survey-based with open-ended items; it is not an in-depth interview service.
• Best for: Restaurant, retail and service brands that need front-line performance and customer opinion side by side.

6. C Space: Best for Ongoing Dialogue With the Same Customers

C Space, part of Escalent Group, says it created the first insight communities and has run them for more than 25 years. Members share what they think over time, so a brand can return to the same people as satisfaction shifts.

• Strengths: Longitudinal context, qualitative moderation, and journey mapping.
• Limitations: A community is a standing investment; it suits a strategic relationship more than a single post-transaction read.
• Best for: Brands that want customers as an ongoing advisory group rather than a sample.

7. Confero: Best for Multi-Location Brands

Confero has conducted customer experience research since 1986, running customer surveys alongside on-site, online and telephone mystery shopping and compliance audits. Surveys reach customers on the web, in app or at the location, and it runs in-store interviews, outbound telephone interviews and inbound IVR.

• Strengths: Unlimited dashboard views by location, and a published client testimonial for a customer exit interview study repeated every two years.
• Limitations: Oriented to front-line and location performance rather than product or proposition research.
• Best for: Regional and national chains in banking, automotive, hospitality and retail.

8. Conifer Research: Best for the Deep Why Behind a Lapse

Conifer is a human-centered research and innovation consultancy with nearly a quarter century of in-person and remote fieldwork, blending ethnographic, quantitative and design research. One published case combined remote interviews and a path-to-purchase survey with current customers, lapsed users and rejectors of a meal kit brand to find where the funnel broke.

• Strengths: In-home and remote interviews and diary studies that surface context a survey never asks about.
• Limitations: Small, deep samples on consultancy timelines; not a tool for monthly satisfaction tracking.
• Best for: A retention problem nobody can yet explain.

9. Forsta: Best for Running the CX Program In-House

Forsta combines what were separate companies, Confirmit, FocusVision, Dapresy, Rio SEO, InMoment and ReviewTrackers, into one experience management platform, with strategy consultants on top. It supports multi-mode data collection, digital diaries, online interviews and focus groups.

• Strengths: One platform for customer, employee and brand experience, used by research agencies and consulting firms as well as brands.
• Limitations: The core is software; for a one-off interview study, confirm whether its consultants or your own team will design and moderate it.
• Best for: An enterprise that wants to own its satisfaction data and tooling.

10. Ipsos: Best for Multinational Programs Under One Supplier

Ipsos runs a global customer and employee experience practice covering research, advanced analytics and advisory, from corporate strategy to operational excellence, alongside its wider research business.

• Strengths: CX and EX under one roof, with a Channel Performance practice that sends mystery shoppers and auditors to stores, digital channels and contact centers.
• Limitations: Scale brings process; a single-market diagnostic can be more than the question needs.
• Best for: A multinational that needs comparable satisfaction measurement across many countries.

Why a CSAT Score Needs an Interview Behind It

A CSAT score compresses an experience into one number, which is what makes it trackable and what makes it silent on cause. Even the most rigorous index works this way. The same ACSI methodology pages describe the score as a weighted average of three survey questions, placed in a model with expectations, perceived quality and perceived value as drivers and complaints and loyalty as outcomes.

A driver model says which lever correlates with the score. It does not say what "quality" meant to the customer who gave you a 2, or what would have changed the rating. An interview adds three things:

1. The reason in the customer's words, which is usually more specific than any attribute on the questionnaire.
2. The sequence of events that turned a neutral experience into a complaint.
3. The counterfactual, what would have made the score a 9.

The Deeper Brand Tracks layer is built on that last question, fielding a small wave of interviews every time a tracker fields so each score change arrives with its explanation.

Reaching Detractors by Phone and WhatsApp

Every channel reaches a different slice of a customer list, so channel mix is a sampling decision, not a logistics one. A detractor who ignores email may still pick up a call or answer a message.

The evidence comes from US hospital patient-experience surveys, one of the few satisfaction programs where survey mode has been randomized at scale. A 2024 randomized trial of 36,001 discharged patients across 46 hospitals found that response rates reached 36.5% under a web-mail-phone protocol, against 22.1% to 24.3% for mail-only or phone-only designs. Gains from adding modes were often two to three times as large for Black, Hispanic, multiracial and Asian American, Native Hawaiian or Other Pacific Islander patients as for White patients.

What Each Channel Changes About Who Answers

• Web link: cheapest and fastest, and it reaches people who read email and click.
• Live or CATI phone: reaches people who ignore email, though telephone response has fallen for decades, a history covered in why telephone response rates collapsed.
• AI phone call: reaches the same people as CATI with no interviewer headcount limit, subject to consent rules for automated calls set out in TCPA rules for AI phone research.
• WhatsApp: reaches customers who live in the app and prefer voice notes to forms, which is why WhatsApp interviews run as a conversation with no link to click.

Alchemic lets the respondent choose among web, WhatsApp and phone inside one study, so a detractor list is not filtered by whoever happens to click an email. Before buying any of these, the questions to ask a vendor about respondent reach turn a coverage claim into something you can check.

When Another Company or Approach Is the Better Choice

An interview study is the wrong purchase more often than vendors admit. These are the cases where another company on this list, or another approach, is the better answer:

1. You need a benchmark against competitors. A cross-industry index such as ACSI, or a large supplier such as Ipsos, answers "are we better or worse than the category" in a way no bespoke interview study can.
2. The problem is front-line execution. If staff skip the greeting, a mystery shop from BestMark or Confero observes it directly.
3. You need a number per store every month. Bellomy or a Forsta deployment tracks every location continuously, which is a measurement system, not a study.
4. The account list is small and senior. Twenty key accounts are better served by an executive interview program, such as Amplitude Research's, or by your own account leads.
5. Nobody can yet explain the lapse. Conifer Research's in-home and ethnographic work watches the routine rather than asking about it, which surfaces context a remote conversation can miss.
6. You get fewer than a dozen detractors a month. A customer experience manager calling each one personally costs less than any vendor.

From CSAT Interviews to a Retention Decision

Interviews earn their cost only when they end in a decision someone owns:

1. Pull the list. Export detractors, lapsed buyers and a comparison group of promoters from the CRM, with consent status attached.
2. Separate recovery from research. When researchers engage in non-research activities, the Insights Association Code of Standards says they must "not permit any direct action toward an individual based on their participation in research without their consent." Route anyone asking for help to service, with their permission, and keep the study clean.
3. Ask for the story, then the fix. Open on what happened and close on what would have changed the rating.
4. Code themes against the journey. Tag each reason to a touchpoint and count respondents per theme, not mentions.
5. Test the fix before shipping it. If the theme points at an app flow or checkout, UI and UX testing on a prototype confirms the change removes the friction.
6. Re-measure. Run the next wave with the same guide so movement is comparable.

Where Satisfaction Research Misleads

Satisfaction data has documented failure modes, and interviews add their own.

• Mode shifts the score. In the randomized HCAHPS mode experiment, telephone and active IVR respondents gave more positive evaluations than mail respondents, with some effects worth more than 30 percentile points in hospital rankings. CMS still adjusts publicly reported HCAHPS scores for survey mode and reran its randomized mode experiment in 2021. Compare scores only within one mode, or adjust for it.
• Response is not random. Whoever answers is a self-selected slice, and without a design that chases non-responders nobody knows which way the slice leans.
• Stated reasons are reconstructions. Customers explain a score after the fact, and a fluent story is not proof of cause. Pair interviews with behavioral data where you have it.
• Small samples travel badly. Forty interviews can name the themes but cannot size them.

Once it has the client's brief, Alchemic designs and tailors the discussion guide to handle these risks before fielding, rather than leaving that work to the buyer.
