Best UX Design Agencies in 2026

frog traces its origins to 1969, when Hartmut Esslinger founded esslinger design in Germany's Black Forest. The firm was renamed frog design after moving to California in the late 1970s. Its early product work included Sony's WEGA and Trinitron lines and the Apple IIc. Other historical clients named by the firm include Lufthansa, Microsoft, GE and Disney. In 2005 Esslinger and Patricia Roller sold a majority stake to Aricent, and frog is now part of Capgemini Invent, the strategy and innovation arm of the Capgemini group. It runs studios in Paris, San Francisco, Bengaluru, Delhi, London, Lyon, Madrid, Mexico City, Milan, Munich and New York. Its UX practice now sits within a wider offer of service design, product strategy and transformation consulting, and that consulting context suits large enterprises more than start-ups.

IDEO was founded in 1991 in Palo Alto by David Kelley, Bill Moggridge and Mike Nuttall. The firm lists among its milestones the first usable mouse for Apple (1990) and its work with PillPack, which Amazon later bought for more than US$750 million. Other listed engagements include Ford's approach to mobility (2017), an innovation lab with Intercorp in Peru (2019) and work on Moderna's culture (2021). IDEO currently names studios in Cambridge (Massachusetts), Chicago, London, San Francisco and Shanghai, and runs labs focused on health, AI and play. It also operates the IDEO U training business and the non-profit IDEO.org. It is closely associated with the spread of "design thinking" as a management method, and its engagements tend to emphasise research, concept development and new-venture design rather than production UI work.

Huge was founded in Brooklyn in 1999. Its own timeline records a London office opening in 2011, Colombia in 2014 and Vietnam in 2021, and it now describes a network of 14 hubs. The same timeline marks 2024 as the year the agency became "independent again" which implies earlier ownership by a larger group. Huge combines UX and product design with brand, marketing and technology work, and is typically hired for large consumer-facing websites, apps and digital platforms. Its offices in Colombia and Vietnam give it lower-cost production capacity alongside its US and UK strategy and design teams.

Fantasy states that it has worked with clients for 25 years. Its published work includes the product experience for 23andMe's market launch, Royal Caribbean's iOS app, the Bronco human-machine-interface design system for Ford, an AI-powered concierge app for Art Basel, the Samsung Galaxy Note 8 launch, and the FuboTV streaming service. It says it helped MasterClass grow from a challenger brand into a widely known name. Fantasy's portfolio is weighted to digital products where interface and brand are hard to separate, such as consumer apps, streaming and in-car interfaces. That makes it a frequent choice for companies redesigning a flagship consumer product.

ustwo was founded in 2004 by Matt "Mills" Miller and John "Sinx" Sinclair, childhood friends. It is a certified B Corporation and majority employee-owned, and everyone who works at the studio is described as a partner. Its site lists London, Malmö, Lisbon and New York. The company is also known for Monument Valley, a mobile game it created, which won a BAFTA and was launched on stage at Apple's WWDC. ustwo has also received Fast Company Innovation by Design awards. Its client work spans digital product strategy, UX and UI design and engineering, and its experience of shipping its own products is a point of difference from service-only agencies.

Instrument is a digital product and brand agency with offices in Portland and New York, plus remote staff. It says it has more than 350 people and has been working for more than 20 years. Clients named on its site include Google, Spotify, Electronic Arts, ServiceNow, Uber and ŌURA. The agency notes that it can draw on specialists across the Stagwell network, which indicates its affiliation with that marketing group, although the page does not describe the ownership structure. Instrument's work combines UX and product design with brand campaigns and websites, and it is often engaged by technology companies for product launches that span marketing and the product itself.

MetaLab describes itself with the line "We make interfaces" and says it designs, builds and ships digital products for start-ups and established brands. It states that it has been operating since 2006. Its home page does not name clients, team size or headquarters, so buyers usually assess the studio through its case studies and references. MetaLab's model of design plus front-end and product engineering in one engagement suits companies that want a production-ready interface rather than research or strategy alone. It is a well-known choice among venture-backed software companies.

Ramotion has been in the industry since 2009 and lists offices in San Francisco, Los Angeles and New York, with a team of about 70. Named clients include Redis, Citrix, Netflix, Salesforce, Stripe and Adobe. The agency says its clients have had more than US$6 billion in exits and raised more than US$1 billion. Its services are packaged around company stage: refresh and repositioning, scale-up brand and design systems, ongoing team extension for UI/UX and front-end work, and preparation for M&A or IPO. The team-extension model is useful for software companies that need a continuing design resource rather than a one-off project.

Clay is a San Francisco-based design agency that states it has 16 years in business and 78 team members worldwide. It offers branding, digital product design, websites, content and development. The client testimonials on its about page come from companies including Wealth, Quartzy, JOKR, Earnin and Viventium. Clay mostly works with venture-backed technology companies on combined brand and product work, such as a rebrand delivered together with a new marketing site and an app redesign. Its scale is similar to Ramotion's, and both are typical of the boutique end of the UX-agency market.

Work & Co is a digital product design and development studio headquartered at 231 Front Street, Brooklyn, New York. Its site carries a copyright range starting in 2013, and its footer links to Accenture's privacy policies, though the page does not describe the ownership. Clients cited on its site include Apple, Google and Nike (as reported by Fast Company), along with Canada Goose, Pfizer and JW Anderson. The studio is known for e-commerce and product experiences that it designs and also builds. It is the youngest agency in this list by visible operating history.
