Market Research Outsourcing and Who to Use in the US 2026

Last updated: 23 September 2026

Quick Answer: The market research outsourcing companies worth shortlisting are Alchemic, B2B International, Cint, Evalueserve, Ipsos, Kadence International, MR4All, Research Optimus, Sago and SG Analytics. They sell four different things: a whole study, fieldwork or sample only, offshore analyst capacity, or a marketplace that bids your brief out. Decide which you are buying before comparing names.

Under the ICC/Esomar International Code, updated in July 2025, a research supplier has to declare its subcontractors upon request. The Insights Association's code carries a similar condition, with an exception where naming a subcontractor would create a competitive disadvantage. Both make disclosure an answer to a question rather than a default, so a buyer who never asks can sign with one company and have the interviews run by another.

Key takeaways

• Full-service firms are accountable for the answer, sample marketplaces for completes, offshore desks for hours.
• A provider's channels decide who can be in your sample before any question is written.
• Subcontractors are disclosed on request under both the ICC/Esomar and Insights Association codes, so ask in writing who runs each stage.
• ISO 20252:2019 was withdrawn on 1 September 2026, so a quality certificate should name its edition.

How This Guide Evaluates Outsourcing Companies and Platforms

Every provider below was checked on its own website on 23 September 2026, and every figure is its own published claim. The shortlist covers each type of provider a buyer meets when searching for outsourcing companies and platforms, keeping only firms a brand could hand a brief to.

Five criteria decided each entry:

1. What you buy: a study, respondents, analyst time, or bidders.
2. Who carries the fieldwork: own panel, facilities and interviewers, or partners.
3. Published reach: markets, languages and panel size, as stated.
4. Engagement model: per project, per complete, retained team, or bid.
5. One concrete limit: where the provider is the wrong call.

GreenBook's directory and the ESOMAR directory were used for discovery only. Both are fast ways to widen a shortlist, and neither runs research itself.

Global Research Outsourcing Providers Compared at a Glance

Rows are alphabetical by provider name, so the order carries no ranking. Reach figures are each provider's own and not like for like.

If the brief is a consumer study you want run end to end rather than staffed, Alchemic's full-service consumer research is one place to start the scoping call.

Ten Research Outsourcing Providers Worth Shortlisting

Alchemic is listed first as the publisher of this guide; the other nine follow alphabetically.

1. Alchemic: Best for a Consumer Study Run End to End

Alchemic is an AI-native research platform paired with a full-service research team, sold white glove or self-serve, for end-to-end consumer research at scale. The team takes a brief, builds the discussion guide, recruits, fields and analyzes, with managed fieldwork or bring your own across 14 markets including the USA and the UK.

Strengths: channel reach. Interviews run on a web link, natively inside WhatsApp with no link and no app, or by outbound AI phone call, and the platform publishes 57+ languages including Hindi, Tamil and Telugu. Its own benchmark puts a 200-interview qualitative study at three days from brief to live dashboard, five to seven for complex work, against four to six weeks for traditional fieldwork. Clients shown on its site include Unilever, Mars, Razorpay and Urban Company.

Limitations: 14 markets rather than ninety, and no normative database built over decades.

Best for: consumer brands that want a qualitative or mixed-method study run for them, including respondents a browser panel tends to miss.

2. B2B International: Best for Business-Buyer Research

B2B International describes itself as a specialist B2B research agency, founded in 1998, with research in 145+ countries, 900+ client brands and more than 4,000 B2B research programs behind it. Its service lines, from brand tracking to pricing research, are built around business buyers.

Strengths: depth in one audience. Recruiting a procurement director or a plant engineer is a different craft from recruiting a shopper, and that screening know-how is hard for a generalist to rebuild.

Limitations: the specialism cuts both ways. A consumer brief is outside its stated focus.

Best for: industrial, technology and professional-services firms outsourcing a study of their own buyers.

3. Cint: Best for Outsourcing Sample Only

Cint calls itself the world's largest programmatic research marketplace. Through Cint Exchange a buyer reaches respondents from more than 800 integrated supply partners across 130 countries, and the company also sells campaign measurement and an AI-moderated interviews offering.

Strengths: coverage and fast feasibility. A 30-country tracker can be scoped against live supply, with many panels blended behind one order.

Limitations: Cint supplies people, not a study. Design, quality review and interpretation stay with the buyer, and blended supply is harder to audit panel by panel.

Best for: teams that already have researchers and survey software and need respondents at scale.

4. Evalueserve: Best for Competitive Intelligence

Evalueserve positions itself as a domain-led AI services firm with 25 years inside client workflows, and says it is trusted by 30% of the Fortune 500. Its solution list includes market and competitive intelligence, commercial and customer intelligence, and procurement and supply chain intelligence.

Strengths: analyst capacity for competitor tracking, market sizing from published sources and a standing intelligence feed, the tasks that eat an internal team's week.

Limitations: its own site leads with intelligence and analytics, not consumer fieldwork. Primary interviews with shoppers are not what it sells first.

Best for: strategy and product teams that need a standing desk-research and intelligence function without hiring one.

5. Ipsos: Best for Multi-Country Programs That Need Norms

Ipsos lists a presence in 90 markets and more than six million authenticated, proprietary panelists, and runs KnowledgePanel in the US alongside custom research, trackers and public opinion work.

Strengths: nearly every method under one roof, local offices in most markets a global brand sells into, and norms accumulated across years of tracking.

Limitations: breadth built for a 20-market program is more machinery than a quick single-market question needs.

Best for: global brands outsourcing multi-market trackers or studies that must be benchmarked against history.

6. Kadence International: Best for Asia-Led Multi-Country Fieldwork

Kadence International describes itself as a global agency offering both data collection and full-service research across Asia, the UK, Europe and the Americas, with offices in 10 countries, work in more than 60 languages and over 30 years in business.

Strengths: flexible scope. Buyers can outsource the whole study or only fieldwork and recruitment, keeping design in house.

Limitations: ten office countries is a real footprint, not a global one; elsewhere, ask who interviews on the ground.

Best for: multinationals and agencies running studies across Asian markets alongside the US or UK.

7. MR4All: Best for Bidding a Brief Out to Many Providers

MR4All calls itself the first global aggregator platform for the research industry. A buyer posts a brief, receives real-time price and feasibility bids from listed providers, picks one and pays that provider directly. Its homepage lists 217+ providers across agencies, data collection (online, phone and face to face), tools and freelancers, in 119 countries.

Strengths: price discovery. Several bids show quickly what a study should cost.

Limitations: the platform connects rather than delivers. Vetting the winning provider, contracting and quality control stay with the buyer.

Best for: experienced buyers who can write a tight brief and want competitive quotes quickly.

8. Research Optimus: Best for an Offshore Desk-Research Team

Research Optimus describes itself as an independent research agency that acts as an offshore team, offering white-label market research and serving clients in the United States, Europe, Australia and New Zealand for more than 25 years. It is part of the Flatworld Solutions network, states a 99.5% SLA completion rate, and includes an FTE engagement among its case studies.

Strengths: cost-efficient capacity, which it names as an aim, and white-label delivery an agency can put its own name on.

Limitations: the service list leans toward secondary research, financial and business analytics. Consumer fieldwork in the buyer's own market is not its center of gravity.

Best for: agencies and consultancies that need extra analysts on report writing, data work and desk research.

9. Sago: Best for Recruitment and In-Person Facilities

The Schlesinger Group site now carries the Sago brand, which cites 55 years in the industry. Its offer spans recruitment, the Sago panel, a data-quality check called SagoVerify, in-person facilities, digital discussions and interviews, and AI-powered research tools.

Strengths: the physical side of research. Focus groups, product clinics and in-home recruits need facilities and recruiters in the right cities.

Limitations: buyers wanting strategy, not just recruits and rooms, should confirm the consulting depth on their brief.

Best for: qualitative teams and agencies outsourcing recruitment, groups and in-person work.

10. SG Analytics: Best for a Retained Research Team

SG Analytics sells end-to-end research and outsourcing support across 75+ countries, with 10M+ B2B and B2C panelists and more than one million in-house CATI respondents. It offers ad hoc, long-term contract and FTE engagement models, and publishes its answers to ESOMAR's buyer questions for sample providers.

Strengths: a team sized to the workload, across primary and secondary research, surveys, phone and focus groups.

Limitations: market research is one practice inside a broader analytics firm, so check who on the account has category experience.

Best for: companies that want a retained research team offshore rather than a sequence of one-off projects.

Which Parts of a Study to Outsource, and to Whom

Which layer to buy depends on what an internal team already covers; the internal build-or-buy split is set out in building an in-house insights function. Rows below run from the widest scope to the narrowest, with names alphabetical in each.

The difference between software and a vendor that actually runs the work is covered in platforms that run the study for you.

How Outsourcing Providers Price a Study

None of the ten publishes a rate card on the pages reviewed. The unit of the quote follows the provider type.

• Full-service firms quote per study, bundling design, fieldwork, analysis and the readout.
• Sample marketplaces typically price per completed interview, and incidence drives the number.
• Offshore research teams quote per project or per full-time equivalent, an engagement model SG Analytics and Research Optimus both list.
• Bidding marketplaces return several prices against one brief, and the buyer pays the winning provider.

The pricing models and the incidence effects beneath them are broken down in what consumer research costs.

Who Reaches the Respondents a Browser Panel Misses

The channel a provider fields through decides who can be in the sample. An online panel reaches people who joined one, and the ICC/Esomar Code's Article 7 asks researchers to be transparent about gaps in population representation.

Reaching everyone else is where outsourcing earns its fee, because that reach sits in the provider's operations:

• In person: recruitment and facilities, which Sago and Kadence International sell.
• By phone: SG Analytics lists more than a million in-house CATI respondents.
• By messaging and outbound AI call: Alchemic runs interviews natively inside WhatsApp with no link to click and no app to install, and places outbound AI phone interviews in the respondent's language.

In India that fieldwork runs from metros and Tier 1 through Tier 2 and Tier 3 cities, with incentives over UPI, bank transfer or global rails; in the USA and UK the same channels can reach respondents who ignore panel invitations. The reach questions worth putting to any vendor are collected in this vendor reach checklist.

Questions That Expose Who Really Does the Fieldwork

Ask these in writing before signing; each rests on a published standard.

1. Who conducts each stage, by company name? AAPOR's disclosure standards list the parties who conducted the research, and the supplier of any panel or list, as items for immediate disclosure.
2. Which subcontractors touch the data? The ICC/Esomar Code (Article 8) and the Insights Association Code of Standards, last updated September 2025, both make this an answer on request.
3. Can we audit collection quality independently? Article 7 of the ICC/Esomar Code lets clients arrange independent checks on data collection and preparation.
4. Where will personal data travel? Article 6 requires consent before a respondent's data crosses jurisdictions, a live question for any offshore team.
5. Where is AI used, and with how much human oversight? The ICC/Esomar Code requires both to be stated; the Insights Association also asks for model type and data source.
6. Have you answered ESOMAR's sample questions? ESOMAR's 37 Questions to Help Buyers of Online Samples give buyers a standard framework for any sample source.
7. Which quality standard do you certify against, and which edition? ISO's own catalogue shows ISO 20252:2019, the research service standard, withdrawn on 1 September 2026 and replaced by ISO 20252:2026. A certificate should name the edition.

When a Rival or Another Approach Is the Better Choice

Several briefs are better served by something other than a managed consumer study.

• The respondents are business buyers. B2B International's decades of B2B recruiting are the stronger choice for a study of procurement heads or engineers.
• The program spans 20+ markets and needs history. Ipsos's 90-market footprint and accumulated norms are what a global tracker needs, and a 14-market provider cannot supply them.
• You already have researchers and only lack respondents. Buying sample from Cint keeps design in your hands and avoids paying for work your team already does.
• The gap is analyst hours, not fieldwork. Evalueserve, Research Optimus or SG Analytics fit a standing desk-research load better than a study-by-study vendor.
• The study needs rooms and physical product. Sago's facilities handle physical product in a way a remote interview cannot.
• Research is continuous and central to the business. At a steady volume, hiring researchers can beat buying projects, and the internal build is the better path.

When Outsourcing Consumer Research Is the Wrong Call

It is the wrong call when:

1. The question is not yet a question. Paying a firm to find out what you want to know is consulting, not research.
2. The knowledge must stay in the building. Repeat insight compounds only if someone inside can query it.
3. The chain has too many handoffs. Agency to field house to panel to coding desk is four places for quality to slip.
4. Speed matters more than depth. A self-serve survey tool beats any procurement cycle on a quick directional question.

Where AI-Moderated Fieldwork Falls Short

Text and voice interviews carry no facial signal, so studies that depend on reading a face need a video mode or an in-person session. How much latitude a system has to leave the guide varies by tool, and a rigid system makes the guide the whole study. No system has been validated as a distress detector, so none should be relied on to notice a vulnerable respondent. 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.

Getting an Outsourced Consumer Study Scoped

Write one page: the decision the study informs, who you need to hear from, the markets and languages, and the deadline. Send it to two or three providers of the matching type, with the seven questions above. Fieldwork modes are compared in data collection companies for market research.
