Top 7 UI/UX Design Agencies for Enterprise in 2026

#1 — IDEO

San Francisco, New York, London, Chicago, Tokyo, Munich | Est. 1991 | $$$$ | 9.7/10

The firm that brought human-centered design into mainstream business practice and has spent three decades proving the methodology works at every scale and in every sector. IDEO's influence on how enterprises approach user research, prototyping, and design thinking is difficult to overstate — but what earns the ranking is current output, not historical importance. Their ability to operate upstream of a brief — mapping problem spaces before proposing solutions — remains unmatched at enterprise scale, where the right question is rarely the one a stakeholder initially asks. When an organization does not yet know what it should be building, IDEO is where you go before you go anywhere else.

#2 — Fjord (Accenture Song)

London, New York, Berlin, Stockholm, and 25+ global offices | Est. 2001 | $$$$ | 9.0/10

Twenty-five years of service design practice across radically different industries and cultural contexts has produced genuine pattern recognition across the full breadth of enterprise transformation challenges. Their NHS work — designing digital health services that must function for an entire national population across every level of digital literacy — is the clearest demonstration of what rigorous, research-led UX looks like when the stakes are highest. Backed by Accenture's consulting infrastructure, Fjord operates at a scale and with a transformation capability few independent studios can match. The right choice when the brief is organizational as much as it is digital.

#3 — Pentagram

New York, London, Berlin, Austin, Shanghai | Est. 1972 | $$$$ | 8.8/10

The world's largest independently owned design consultancy, structured as an equal partnership of star designers rather than a conventional agency hierarchy. Pentagram's partner-led model means every enterprise engagement is directed by a principal with decades of recognized work — not delegated to juniors. Their digital practice has expanded significantly, producing identity systems, product interfaces, and interactive experiences for some of the most recognized brands on earth: Mastercard, Slack, Citibank, Verizon, Warner Bros. The combination of graphic design heritage and modern digital fluency makes them uniquely capable when brand and interface must speak with one voice across a Fortune 500 enterprise.

#4 — Designit

designit.com

Copenhagen + 14 global offices | Est. 1991 | $$$$ | 8.8/10

Wipro's global experience innovation company, with 500+ designers, analysts, strategists, and marketers across 14+ studios from Aarhus to Australia. Designit operates where business strategy, UX, and technology meet — working primarily with large organizations facing structural and operational change. Their work goes beyond individual products or interfaces to help enterprises rethink how services are designed, delivered, and experienced across entire systems: digital platforms, customer journeys, internal tools, and organizational models. Clients include Microsoft, IKEA, and BMW. Backed by Wipro's consulting and engineering infrastructure, Designit handles the kind of multi-market, multi-year transformation programs that few independent studios can deliver end-to-end.

#5 — Huge

New York, London, Toronto, Atlanta, Los Angeles, Buenos Aires | Est. 1999 | $$$$ | 8.7/10

Founded as a web agency, Huge builds brand programs with digital customer experience at the center — not as a downstream application of decisions made in a more traditional branding process. When an enterprise brief spans positioning, digital products, CRM, and environmental design simultaneously, they have the breadth and internal structure to coordinate all of it without losing coherence. Clients include Google, IKEA, P&G, NFL, Delta, J.Crew, and HBO. Best for organizations where brand and experience are genuinely inseparable problems and the program requires a single agency partner with the scale to coordinate across multiple workstreams.

#6 — Work & Co

work.co

Brooklyn, Portland, São Paulo, Copenhagen, Belgrade | Est. 2013 | $$$$ | 9.4/10

Founded by former executives from R/GA, Huge, and Google with a single defining ambition: build digital products that actually ship and perform at scale. Their Apple Music interface, Virgin America booking experience, and Google Arts & Culture app all succeeded as deployed products rather than design concepts diluted in development. For enterprise clients who need design discipline and technical depth operating as one team — not handed off across vendor boundaries — Work & Co is the standard. The right pick when the enterprise brief is "ship something that works at scale," not "produce a transformation roadmap."

#7 — Fantasy

fantasy.co

New York | Est. 2010 | $$$ | 8.8/10

Technical depth in real-time rendering, WebGL, and interactive systems combined with the design sensibility to use those capabilities purposefully rather than decoratively. For enterprise clients, Fantasy delivers a specific value: the ability to operate at the frontier of what browsers can render while navigating the brand and stakeholder complexity of major enterprise programs. Their Reddit work demonstrated an ability to navigate genuine UX complexity at scale — one of the most structurally demanding community platforms in existence. Their Stripe and Google work speaks to enterprise infrastructure brand experience. Selective about commissions.
