Best UX Design Agencies in Seattle (2026)

Introduction

Seattle has one of the deepest UX benches in the US, and the 12 agencies below cover product design, UX research, service design and digital experience work. They were chosen for recent projects, the strength of their client lists and a confirmed office in Seattle, Bellevue or Kirkland in 2026.

The local market grew up around Microsoft and Amazon, and many of the firms here count both as clients. Ownership has shifted over the past few years. Blink, founded in Seattle in 2000, has been part of the Indian IT services group Mphasis since 2021, and in July 2026 Bellevue's Fresh Consulting bought the assets of Product Creation Studio to add medical device development to its design and engineering teams. Substantial, a long-standing Seattle product studio, now presents itself as an AI implementation partner.

Every agency here has an active Seattle-area office in 2026. The list runs in no fixed order of merit, since the right choice depends on whether you need research, interface design or a full product team. Studios whose main work is identity, packaging or industrial design are covered on separate design and branding pages.

2. Blink

Blink was founded in Seattle in 2000 by Karen Clark Cole and Kelly Franznick. Mphasis bought it for $94 million in 2021, when it had more than 130 staff, and the firm kept its name. Seattle is still its headquarters, on Western Avenue, with further studios in San Diego, San Francisco, Boston, New York and Bengaluru.

Its services run from UX research and product design to AI strategy and embedded research staff, under the banner "Evidence-driven Design". Recent projects include the redesign of NASA.gov and research with Google on AI and neurodiversity, and clients have included Amazon, Microsoft, Starbucks and JPMorganChase. It is a strong pick when a team needs research to settle a product decision.

3. Fresh Consulting

It is headquartered in Bellevue with offices in Bangkok, Mexico City and San José, Costa Rica, and has more than 350 staff across strategy, experience design, software, hardware, robotics and AI.

In 2026 Slalom became an OpenAI Advanced Partner and was named on Forbes' list of the World's Best Management Consulting Firms. It is a natural fit when design work sits inside a larger technology or data programme.

5. Tactile

Projects include the Milwaukee Redstick digital level, a scissor lift controller for Genie, a design language for ecobee and Microsoft's Azure Percept development kit. Its client list also takes in Amazon, Samsung, Intel, Bose and Philips. It is a good option for equipment makers whose product depends on a clear on-device interface.

6. UpTop

It is co-owned by Craig Nishizaki, who runs the business side, and Michael Woo, who leads design, and its office is on South King Street. The firm says it has been rated a top UX agency in Seattle on Clutch for eight years running.

Its focus is what it calls UX modernisation: redesigning dashboards, internal tools and customer apps for service-driven organisations in healthcare, HR, financial services and logistics.

Services cover qualitative and quantitative research, usability testing, participant recruitment, accessibility research and evaluation of AI products, and it published a report series on evaluating enterprise AI in September 2026. Clients include Amazon, Google, Microsoft, Meta, Expedia and Samsung. It suits product teams that need research capacity or recruiting at short notice without building a lab of their own.

Over the years the studio has collected Communication Arts Awards of Excellence and Webby Awards. It is the one to call when the interface is a touchscreen in a gallery or a media wall in a lobby.

9. Intentional Futures

Its first major project was designing and launching the Big History Project between 2010 and 2012, and education technology remains a strength. Clients include the City of Seattle, CommonLit and the National Forest Foundation. It is better suited to service and programme design for mission-driven organisations than to screen-level interface work.

10. Forum One

Independent · Seattle · forumone.com

Forum One is a digital agency founded in 1996 that works from two hubs, Arlington in Virginia and Seattle, its West Coast base, with a remote-first team of more than 100 strategists, designers and technologists.

Services cover digital strategy, UX design, content architecture and development. Clients include NRDC, the Smithsonian Institution, the Howard Hughes Medical Institute, the National Gallery of Art, AARP and the US Department of Education. It suits public-sector and non-profit teams with large, content-heavy websites.

Services cover field studies and interviews, usability testing, journey mapping, service design, interface design and prototyping. Recent work includes Trially.ai, which uses AI to recruit patients for clinical trials. The narrow focus helps on clinical software and connected devices used by both clinicians and patients.

12. Turnstyle

Independent · Fremont · turnstyle.studio

Turnstyle is a strategic brand and web design studio in Fremont that brings strategy, design and technology into one team. Its journal covers content management design, marketing for architecture and engineering firms, and how to explain AI and deep technology products on the web.

Clients include AWS, Microsoft, Starbucks, Nordstrom, Seattle-Tacoma International Airport and Treehouse. It is a good fit for technical companies whose website has to explain a complicated product to buyers who are not engineers.

What to look for in a Seattle UX design agency

Decide first whether you need research, design or both. Seattle has specialists at each end, such as User Research International for lab studies and recruiting, and full-service firms such as Blink, Fresh Consulting and Slalom that take a product from discovery to build. For a single study a specialist is often quicker to start. Longer programmes tend to run more smoothly with one team carrying the work from research through to build, because fewer handovers are needed.

Ask for work in your domain and find out who did it. Medical software, enterprise tools, public-sector services and consumer apps each have their own users, constraints and review processes. A firm that has shipped work for a large Seattle technology company may still be new to clinical settings or government accessibility rules, so ask to speak to the researcher or designer who led a comparable project.

Many Seattle clients already run in-house design teams with their own design systems. Agree at the start how the agency will work with that team: who owns the Figma files, whether new components go back into the shared library, and how designs are handed to engineering. Settling this early avoids rework when the agency hands over.

Finally, ask how research material and approvals will be handled. A single round of usability testing produces recordings, transcripts, consent forms, notes and a findings deck, and design reviews add prototypes and comments on top. Agencies that keep this in one searchable place, and share findings with stakeholders in a form they will open, leave clients with research they can reuse after the engagement ends.

How Fabric helps UX design teams

Fabric gives a UX team one workspace for research, design files and client feedback, with AI search across all of it. The setup for UI and UX agencies follows how most product engagements run, with a space per client or product holding briefs, research, flows, prototypes and review notes.

Research sessions can be uploaded and transcribed automatically, with clickable timestamps that jump to the moment a participant said something. Search works by meaning across transcripts, notes, PDFs and images, and across connected apps such as Google Drive, Dropbox, Notion and Gmail, so a question like "where did users get stuck at checkout" can return clips and notes from several studies.

For design reviews, a canvas can hold live Figma embeds next to screenshots, sticky notes and journey maps. Specs and research reports can be marked up with highlights and comments through annotations on PDFs and documents, and timestamped comments on video and images are coming soon. Findings decks can be published as a web page with password protection, and link analytics shows when each named stakeholder opened them and for how long.

On Team plans, self-writing docs can maintain a user research repository with interview summaries, findings and recurring themes, drawn from meetings and the workspace. New designers and researchers can read what earlier studies found before planning the next one.

Password protection and link analytics are included on Pro and Team plans, and self-writing docs on Team plans from $125 a month. See plans for teams.
