Best UX Research Agencies (2026)

team collaborating with sticky notes

The short answer

Isadora Agency, Designit and EY Studio+ lead this list. Isadora Agency is the best for mid-market and enterprise teams that need user interviews, card sorting and usability testing before a website or product is redesigned, run by the designers who then build it. Designit sells design research as its own offering. EY Studio+ adds researchers to consulting-led customer experience programs.

UX research gives a design team evidence about what customers need before it commits to a redesign. The work runs through interviews, usability sessions, field studies and surveys, and it ends in findings designers can act on. Most firms on this list sell research together with the design work it informs. Nielsen Norman Group sells it as a standalone study and leaves the design to the client.

The ranking weighs the range of research methods each firm shows on its own site, evidence that findings changed a product or website, how participants were recruited and studied, and how a company would buy the work.

Methodology

We read each firm's own website: research service pages, case studies, about pages and published prices. A firm qualified only if it showed named or clearly described research work there, such as interviews, usability testing, field studies or surveys run for a client, and a list of methods with no project behind it didn't count. We then counted the methods each firm combines. In its case studies we looked for research with the product's real users that changed a design decision. We also noted which firms sell research on its own as a standalone study. Prices and headcount are shown only when a firm states them, and an empty field means it doesn't.

Research-led website and product redesigns with moderated user testing

Founded in 2009, Isadora Agency designs and builds websites and products, and its projects for mid-market and enterprise organizations start with research. The practice combines audience research, competitive benchmarking, analytics auditing, user interviews, focus groups, card sorting and stakeholder workshops, and designs are tested in moderated sessions with real users. For Brookfield Residential, a homebuilder and land developer, Isadora has run a multi-year UX partnership. Research with teams across the US and Canada shaped a design system that scales across regions and an interactive community map. For Smith, an electronic components distributor, a competitor review and stakeholder interviews produced the personas and user journeys behind a new site built to earn buyers' trust and route them to sales.

Design research inside a global network of experience design studios

Designit has belonged to Wipro since 2015 and traces its start to 1991, and it works from studios in cities that include Copenhagen, Madrid, Munich, Oslo and Seattle. Design research is one of its named offerings, and it covers users and the wider ecosystem around them before design begins. When a Japanese online bank wanted to serve expatriates, Designit's team combined desk research with interviews to learn what foreign residents expect from banks in Japan and which currencies they use, then shaped an English account-opening app and an informational website around three findings. For WHYY, the public media organization behind the radio show Fresh Air, the team interviewed listeners and other podcast creators, then tested new product ideas for the show's archive with financial models and a survey.

Customer and employee research inside EY's experience practice

EY Studio+ is EY's customer experience, marketing, sales and service practice, launched in June 2025. For SkiStar, which runs ski resorts in Scandinavia, the team ran strategy workshops that reached every full-time employee as well as its leadership, and SkiStar later signed up families to test new activities. For an unnamed investment advisor building a self-guided investing journey, a studio team of strategists, writers, developers, product owners, researchers and interface designers mapped customer journeys and evaluated the product's copy. Its client work also includes a brand and launch campaign for a men's fertility company and the launch of a sustainable direct-to-consumer brand.

Ethnography and user research for transportation and industrial products

Teague is a design company founded in 1926 and fully employee-owned. The expertise listed for its road usage work covers ethnography, market research and analysis, user and stakeholder interviews, and user experience research. For five years its researchers and designers have worked with the engineering firm CDM Smith and several state transportation departments to study a road usage charge, a pay-per-mile alternative to the gas tax. The Kansas project was qualitative research meant to give residents a voice before any pilot. It opened with strategy workshops in which agency stakeholders agreed on what the study should learn and whom it should learn from, and participants then worked through a toolkit that let them design their own version of the policy step by step.

Mixed-method user research inside an experience engineering firm

Ciklum's team mixes engineers with experience designers, consultants, CX researchers and product strategists. For a trading app that served both consumers and investors, Ciklum ran a two-phase, mixed-method research program. In-depth interviews and usability tests came first, to understand each group's habits and unmet needs, and a survey and three rounds of desk research followed to check the findings at scale. On Bytes' B2B marketplace, the company embedded a user researcher in the product team to run in-depth interviews and concept tests that shape the roadmap.

Covers

Not the right fit when: You need research without an engineering partner; Ciklum's cases pair researchers with build teams.

User research and inclusive design across NTT DATA's design studios

Tangity is the design studio network of NTT DATA, which opened its Spanish hubs in 2024. Its services list includes user research, inclusive design, accessibility, service design and product design. In aida, a non-profit research project from its Milan studio with NTT DATA, the team set out to design for children with autism spectrum disorder. It combined desk and field research with close work alongside people who live with the condition, then used that research to design a dataset that kept human biases out of the AI model. The result was a kit and an app that give parents and educators information about a child's status and suggest ways to communicate.

Customer research and usability testing labs within EPAM

EPAM Continuum is the consulting and design arm of EPAM, the software engineering company. Its service menu links to Transformative Research and Insights, which covers customer research, resonance and usability testing labs, a research center of excellence and help for companies building in-house research teams. That work runs through the EPAM Global Research Institute, which studies sources such as biometrics and market signals. On the design side, EPAM Continuum redesigned the brand and customer experience of XKD and added new service touchpoints for its customers, and its client work also lists MAPCO and Vue.

Usability research and training since 1998

Nielsen Norman Group was founded in 1998 by Jakob Nielsen and Don Norman and is led today by Kara Pernice as president and CEO. Its consulting arm sells research and assessment alongside training. A rapid user test typically involves five to 10 users over three days of moderated sessions, with the client's team observing and a report of prioritized recommendations at the end. Competitive tests compare a product side by side with rivals, and quantitative studies run with 20 to 200 users over one to four weeks to set benchmarks. Customized research studies questions such as user motivation and conversion problems. More complex studies with several audiences or designs usually run $80,000 to $150,000.

Not the right fit when: You need the redesign itself; NN/g's consulting stops at testing and advice.

Research is worth buying when a decision depends on it

A study earns its fee when the team already knows which decision it can't make, such as which audience the site should lead with or why sign-ups stall at one step. A brief framed around that decision keeps the study small enough to finish on time. Open-ended discovery suits the start of a new product, and it needs a deadline and a named owner for its findings. A useful proposal names the decision, the methods, how many participants each method needs and how findings will reach the designers.

Recruiting decides what a study can show

Recruiting deserves as much planning as the discussion guide. B2B studies need participants with the right role and seniority, and finding them can take weeks. Consumer studies usually screen people on behavior, such as how often they use a product. Teague's road usage research for state transportation agencies, for example, opened with stakeholder workshops that agreed on the study's goals and its participants. Mixing methods also helps, because a survey can test at scale what a handful of interviews suggested.

What a UX research engagement includes and costs

A research engagement usually starts with a short alignment phase of stakeholder interviews and a review of existing analytics and past studies, and it ends in a written plan that sets the research questions and the participant profile. Fieldwork follows, through interviews, usability sessions, diary studies, surveys or field visits. The team then turns its notes into findings and personas and presents them in a readout. Nielsen Norman Group publishes starting prices for standalone studies: $40,000 for a rapid user test and $70,000 for a quantitative study. Research bundled into a website or product redesign is usually priced as part of that project, and at Isadora Agency those projects start at $95K. Consultancy-led programs quote research as one workstream among several.

Frequently asked questions

How much does a UX research agency cost?

Price depends on how many methods and participants a study needs. Nielsen Norman Group's published prices give a floor: rapid user tests start at $40,000, and studies covering several audiences or designs typically cost $80,000 to $150,000. Recruiting hard-to-reach participants, such as senior B2B buyers, adds time and cost. Research sold inside a redesign is priced with that project.

How long does a UX research project take?

A focused usability study is the quickest format. Nielsen Norman Group's rapid tests run three days of sessions, with recruiting before and the report after. Mixed-method programs take longer because each phase shapes the next. Ciklum's trading app program, for example, ran interviews and usability tests in its first phase and a survey in its second. Recruiting adds time too, especially when participants need a specific job title or must already be customers of the product.

What is UX research?

UX research studies how people use a product or website and where they struggle with it, so design decisions rest on evidence. It includes interviews, usability testing, surveys, field studies, card sorting and analytics review. Isadora Agency's research service, for example, runs competitive benchmarking, analytics auditing, journey mapping and moderated sessions in which real people try early wireframes and later polished screens, and the findings feed straight into the design.

How do you conduct user interviews?

A good interview round starts with a short list of questions the team needs answered and a screener that recruits the right people. Sessions follow a loose guide and ask people to walk through recent, real occasions when they used the product or tried to solve the problem it addresses. Afterward the notes and recordings are sorted into themes that the design team can act on.

How do you create a user persona?

A persona should be built from interview and analytics data. That data is grouped by goals and frustrations, and each persona summarizes one recurring pattern, with a name and the tasks that matter to that person. Isadora Agency built personas this way for Smith, an electronic components distributor, after a competitor review and stakeholder interviews. They stay useful when they're revisited as the audience changes.

Why does user research matter before a website redesign?

Research shows the team what the site's real audiences need before design decisions are made. Interviews and usability sessions reveal which content people look for and where they get lost on the way to contacting sales. Isadora Agency's work for Brookfield Residential started this way, with stakeholder interviews and user journeys across regional teams. Acting on findings before design begins also spares the team rework after launch.
