Best UI UX Design Companies in USA for Complex B2B, Startups, and Everything in Between

Finding a great UI/UX design agency in USA is hard. Not because there aren’t enough of them, but because every list sounds the same. You get a handful of familiar names but no real insight into who’s actually good for your product.

So we did the work for you. We reviewed dozens of design companies – some big, some boutique – from East Coast studios to West Coast product labs to remote teams with deep U.S. client lists. We looked real case studies, client feedback, industry depth, and design-to-dev handoff quality.

The result is a diverse shortlist of 8 top UI/UX design companies in the United States, from those handling complex B2B SaaS to teams building zero-to-one AI products.

1. Neuron: best for enterprise UX

Neuron is the agency that can turn your enterprise tool into a workflow people speed through on a coffee break. 

Head-quartered on San Francisco’s 650 California Street (with satellite talent from Boston to Bogotá), this studio lives for enterprise UX: procurement flows, medical-device CRMs, recruiter dashboards, AI-powered risk tools. They call themselves a special-ops design unit; clients call them the reason user-training budgets suddenly shrink.

Their portfolio includes companies solving real workplace problems: from Jobble to Vendr, they consistently turn complex business processes into intuitive digital experiences.

Case snapshots

• Jobble: Built a self-serve ad platform so recruiters can sync their ATS and manage applications without relying on third-party agencies.
• AcuityMD: Rearchitected this medical-device CRM around the sales funnel and added mobile field-notes, helping reps see the right data sooner.
• Vendr: Designed a drag-and-drop workflow builder that lets procurement teams automate SaaS requests end-to-end.
• Flo Health: Enhanced the women's health platform with mobile application design services, focusing on report features.

➕ What clients love

• Issues spotted before they explode: Neuron’s designers flag workflow potholes long before they hit engineering sprints.

• Senior-only involvement: Founders and principal designers stay hands-on from kickoff through hand-off (no junior swap-outs mid-project).

• Proof-over-pretty: Every pixel is backed by live user research and tests, so designs win in the wild, not just in slide decks.

• Smart creativity: They mix fresh ideas with strategic foresight, which helps in identifying and implementing innovative solutions.

• Embedded teammates: Clients say the line between “us” and “them” disappears fast, speeding decisions and trust.

⚠️ A few watch-outs

• Premium rates: $150-$199/hr fits funded scale-ups and mid-market teams; seed-stage startups may need to budget carefully.

• Revision boundaries: Some clients report confusion about how many design iterations are included in their agreements.

• Small by design: This shop can book up fast, so make sure to secure your slot a month or two in advance if you’re eyeing a Q4 launch.

• Industry depth: While their B2B expertise is strong, some clients feel Neuron could benefit from deeper knowledge of specific industries.

2. Cieden: best for complex B2B & SaaS

Cieden is the team that turns confusion into clarity. Founded in 2016 by siblings Yurij Mykhasyak (a former design professor) and Iryna Serednia, the agency began with a simple mission: bring together brilliant design minds to solve the toughest UX problems.

Fast forward to today, and Cieden is a 42-person, fully distributed team across seven countries that plugs seamlessly into U.S. product squads. They make complex tools, like AI interfaces, healthcare compliance platforms, and fintech dashboards feel intuitive instead of intimidating. 

From AI-powered risk dashboards to patient portals and sales-intel CRMs, they specialise in “can’t-mess-this-up” B2B software where every second saved (and every audit trail kept) shows up on the balance sheet.

Case snapshots

• Blizzard: Helped Blizzard overhaul their internal CMS, closing key feature gaps and streamlining content workflows. 
• Apollo: Redesigned the sales intelligence platform's UI and prototyped hyper-personalized AI messaging flows.
• MedEntry: Revamped the medical school prep platform with improved navigation and gamification elements.
• Sitenna: Made telecom workflows far more intuitive, simplifying complex acquisition and management processes. The redesign helped them secure $5.1M in funding.
• Lykon: Redesigned core user flows and added a flexible, personalized meal planning feature, boosting their NPS by 135%.

➕ What clients love

• Measurable impact fast: Clients often see results quickly after a Cieden redesign. Think 4× audience growth, 35% more traffic, and 12% lower bounce rates. 
• Compliance without compromise: Whether it’s HIPAA, AML, or KYC, Cieden knows how to navigate strict regulations without making the user experience feel stiff or frustrating. 
• AI that feels natural: Instead of bolted-on features, they integrate machine learning and AI capabilities that feel like they were always part of the product.
• Clear communication: Real-time Slack updates, detailed progress tracking, and regular demos keep everyone aligned without micromanagement.
• Senior-level thinking: Experienced designers stay involved from discovery through handoff.

⚠️ A few watch-outs

• No in-house developers: Cieden partners with trusted dev teams and can help manage the handoff, but if you’re looking for an all-in-one shop, just know that’s not their model.
• Scope can grow fast: Mid-project feature additions can inflate budgets, so clear upfront alignment helps manage costs.
• Very detailed reporting: Their progress reports and time tracking are super thorough, which is great for transparency but can sometimes feel like too much detail for execs who just want the high-level view.

3. Momentum Design Lab: best for fortune-grade UX

Fresh off their 2023 acquisition by HTEC Group, this Silicon Valley agency has spent over two decades turning big ideas into products people talk about.

From their Palo Alto headquarters (with offices spanning NYC, London, and Sydney), this studio specializes in multi-stakeholder approval flows, real-time financial dashboards, AI-powered risk assessment tools, and healthcare platforms where UX mistakes have real consequences.

With a track record of serving Fortune 100 companies like Citibank, Morgan Stanley, and Bayer, Momentum has become the strategic design partner for enterprises that can't afford to get their digital products wrong.

Case snapshots

• Bitstamp: Redesigned the crypto trading platform for better UX, earning a UX Design Award and securing a top 10 crypto exchange ranking.
• Technomic: Unified scattered datasets into a single search-first experience, cutting query time from minutes to seconds.
• Matillion: Reenvisioned ETL suite and rolled out a unified design system across web & desktop tools.
• Piplsay: Improved market research tools to deliver real-time consumer insights and streamlined brand connections.

➕ What clients love

• Proactive communication: As one CEO put it, "if a meeting is set up for 10 minutes, it takes 10 minutes, and we're done." They use tools like Basecamp and provide weekly reports without being asked.
• Developer-ready files: Engineering teams love working with Momentum's detailed wireframes and clean Figma handoffs.
• Budget honesty: They'll tell you when they're coming in under budget rather than burning through hours.
• Rapid domain uptake: Clients noted their ability to quickly adapt to a new industry and understand a technical subject.

⚠️ A few watch-outs

• Premium positioning: At $150-199/hour with a $25k minimum, Momentum isn't cheap, but clients consistently say the value matches the price.
• Handoff hiccups: Some report small inconsistencies during engineering handoff: Figma designs may export with minor spacing or color issues.
• Sync-heavy culture: They favor synchronous meetings over async feedback, which can slow down teams that prefer quick Slack exchanges.
• Gentle advisors: Momentum will solve what you ask for, but some clients wish they’d push bolder ideas unprompted.

4. MetaLab: best for zero-to-one products

 If you need the team that helped shape Slack’s first interface and Midjourney’s “Rooms,” MetaLab is who you call. 

Founded in 2006, the studio sits under Andrew Wilkinson’s Tiny umbrella and operates like a nimble startup inside a larger network of software companies. From brand-new consumer apps to enterprise reinventions, their hallmark is polished UX that scales to millions.

From their Vancouver headquarters, this 200+ person powerhouse has perfected the art of zero-to-one product creation. Yes, we snuck a Canadian agency into our USA list, but with serious American presence through their client work and conference circuit. 

Case snapshots

• Suno AI: Built the app for the fastest-growing AI music platform that rocketed up the charts <24 h post-launch. 
• Midjourney Rooms: Designed a multiplayer ideation space for 3 M DAU, built entirely via Discord async.
• Ro Health: Transformed a men's health startup into a comprehensive healthcare platform, unifying 8 care brands and 600+ design-system components.
• Atomic Habits App: Partnered with bestselling author James Clear to turn his habit-formation system into an app that hit top 10 in the App Store.
• Upwork Work Hub: Repositioned job board into a full marketplace, helping drive 68% revenue growth since 2020.

➕ What clients love

• Building like they own it: MetaLab approaches every project with founder-level commitment, often becoming integral to client teams rather than external vendors.
• Full-stack thinking: They handle everything from strategy through engineering, delivering shipped products rather than static designs.
• AI-first approach: They’re currently at the forefront of AI product development, with successful launches for Suno, Midjourney, and other AI platforms.
• Track record you can bank on: 18 unicorns and 2.2 B users give enterprise stakeholders political cover to choose them.

⚠️ A few watch-outs

• High entry ticket: $100k+ minimums and a senior-heavy roster mean early-stage startups might need significant funding to engage.
• High selectivity: Focus on breakthrough products means they turn down projects that don't meet their innovation bar.
• Time-zone juggling: Fully-remote talent is worldwide, which is great for round-the-clock velocity, but you’ll want a clear comms cadence.
• Full-service commitment: As both design and engineering shop, they prefer complete product builds over design-only handoffs.

5. Ramotion: best for brand + product design

Born in San Francisco in 2009 (and now spread across the US, EU, LATAM, and the Caucasus), this boutique studio treats branding and product design as one continuous system. 

They’ve revamped Firefox’s master brand, multiplied Turo’s self-service rate by 58%, and turned Clearbit’s “data-provider” website into a platform that helped court HubSpot’s acquisition team.

Their sweet spot is companies with serious tech leverage who need their visual identity to match their ambitions. Whether you're a seed-stage AI startup or a Series C fintech platform, they know how to make complex products feel approachable.

Case snapshots

• Firefox: Built a scalable master-brand and icon system that lets Mozilla launch spin-off products (VPN, Relay, Monitor) without ever diluting the fox.
• Turo: Redesigned the self-service support portal, lifting the self-serve score by 58% and trimming support workload 30%.
• Clearbit: Did full website overhaul that sharpened positioning and improved conversion rates — one of the factors that helped pave the way for HubSpot’s $150M acquisition.

➕ What clients love

• Speed when it matters: Teams consistently mention how fast Ramotion moves through design iterations. One client got 20 logo sketches back in just 2 days!
• No hand-holding needed: Once they understand your vision, they run with it. Clients mention being able to explain what they want without micromanaging every step.
• Process transparency: Daily video updates and shared documents keep everyone aligned across time zones, with better communication than some local agencies.
• Global perspective: 24/5 relay between EU design crew and US product owners shaved days off feedback loops during the Firefox re-brand.

⚠️ A few watch-outs

• Project timelines can shift: Like most creative agencies, initial estimates sometimes stretch as projects evolve.
• Quiet early on: Don't expect bold opinions right away. You might need to pull insights out of them before they feel comfortable pushing back on your ideas.
• Design file complexity: Their thorough approach means lots of detailed layers, which can make handoffs to external developers a bit more involved than expected.
• Remote communication quirks: When working remotely, important details can get lost in email threads, leading to small misalignments.

6. Glow Design Agency: best for subscription UX teams

Glow’s model is straightforward: you subscribe to an experienced product-design squad instead of recruiting one from scratch. 

From discovery workshops through Figma files, this Delaware-based crew (with talent spanning from Ukraine to Poland) covers UX research, UI, motion, and brand while leaving engineering to the client. Most engagements start with a three-day trial, then continue month-to-month at a fixed rate, which appeals to founders who need predictable burn and steady velocity. 

Their client list spans fintech dashboards, EV-charging apps, and AI assistants: from Lendflow's embedded credit infrastructure to Dropcall's 18-language AI assistant. 

Case snapshots

• Beast: Defined end-to-end UX and branding for a Tesla car-sharing app; beta users rated usability 4.8/5.
• LiquidSpace: Reimagined the workplace-rental B2B flow; intuitive booking and onboarding screens now drive 50 %+ engagement.
• Lendflow: Designed embedded-credit infrastructure interfaces that let SaaS teams drop lending features in like Stripe.
• JUCR: Built a pan-European EV-charging app that rocketed to #26 in the App Store days after launch.

➕ What clients love

• Grasping complexity instantly: CEOs report that Glow understood their multi-layered products faster than any previous design team.
• Delivering under pressure: Clients mention getting work completed in days when they had urgent deadlines, including a complete video production in a week and a half.
• Competitive rates: At $50-99/hr with their expertise level and client results, they offer strong value compared to similar specialized agencies.
• Structured but flexible: Teams praise their organized design process and ability to adapt when requirements shift mid-project without missing deadlines.

⚠️ A few watch-outs

• Developer handoff polish: One client mentioned room for improvement in creating better processes for handing work off to dev teams.
• Timeline stretch risk: Extra iteration rounds can push a delivery a couple of days past the first estimate (common in design, just schedule a buffer).
• Head-count surge for XL scopes: Massive builds may require Glow to staff up; confirm capacity early if you’re planning a multi-track program.
• Design-only shop: They don’t code, so if you need engineering, budget for a dev partner or in-house team.

7. Dreamten: best for small-team, big-client UX

Dreamten is a senior-only crew headquartered in North Carolina with talent satellites in the UK, Ukraine and Sri Lanka. Since 2014 they’ve skipped the middle-management bloat, embedding directly with product teams to turn app ideas into revenue-generating experiences. 

Their work has helped a fundraising platform triple year-over-year growth, pushed a conversation-intelligence app to #1 on the Zoom Marketplace in eight weeks, and powered a pet-care re-platform that doubled navigation engagement the day it went live. 

The agency’s calling card is strategic UX married to front-end code you can drop straight into a sprint backlog.

Case snapshots

• Fathom: Designed conversation intelligence software that hit #1 on Zoom Marketplace with 150K+ users in 2 months.
• Ubiquity: Rebranded a retirement platform, which drove 17% increase in qualified leads and 120% boost in organic traffic.
• Offline: Contributed to the restaurant club app achieving 100% YoY growth and 4.8 app store rating.
• GiveForms: Built a fundraising platform growing 300% annually with 4,000+ customers and 30,000+ monthly visitors.

➕ What clients love

• Real results: Clients consistently report significant metric improvements, from doubled conversion rates to 650% increases in key actions.
• Business-first thinking: Dreamten starts with revenue goals and works backward to design solutions that drive growth.
• Startup speed, enterprise quality: Small team means fast decisions and quick iterations, but with the strategic thinking that impresses Fortune 500 clients.

⚠️ A few watch-outs

• Team capacity: At 8 people, they book up fast. Expect to plan projects ahead, especially for larger engagements.
• Development limitations: They focus on design and partner with your dev team rather than handling full-stack development in-house.
• Tooling alignment: some clients needed extra effort mapping Figma/Tailwind assets into existing dev stacks.

8. WANDR studio: best for security-sensitive SaaS UX

WANDR is the agency that helps security-sensitive SaaS teams ship products users master before their coffee gets cold, without a manual.

Head-quartered on Los Angeles’ Wilshire Boulevard (and run day-to-day in channels that span Mexico City, Bogotá and Porto), this studio lives for heavyweight B2B UX: cyber-risk dashboards, fintech portals, recruiter CRMs, AI analytics. Clients (from U.S. Space Force to Tenable) credit WANDR’s research-first playbook for slashing onboarding time and boosting renewals.

Case snapshots

• Fortress: Built a system that increased platform adoption 45%, customer satisfaction 25%, and decision-making speed 40%.
• Tenable: Took their legendary Nessus scanner and made it work for both security pros and regular IT folks.
• Avail: Unified everything and made their subscription program understandable. Task completion improved 40% and program comprehension shot up 112%.

The methodology behind our top UI/UX design agency picks in the USA

This isn’t another list built from SEO results or recycled agency directories. We evaluated dozens of design agencies across the U.S. and remote-first teams with a strong American presence. Some were household names, others were niche specialists flying under the radar, but all were vetted with real product teams in mind.

Here’s what shaped our selection:

• Portfolio depth and complexity: We looked beyond visuals. The agencies featured here have dealt with tough UX challenges: multi-step workflows, compliance-heavy industries, and AI interfaces. Not just marketing pages or “coming soon” prototypes.
• Real client outcomes: Case studies were a must, but metrics mattered more. We prioritized agencies that could point to tangible impact: better conversions, retention jumps, funding wins, or 5-star user feedback post-launch.
• Breadth of experience: We favored studios that adapt to multiple sectors, from complex B2B tools to zero-to-one consumer apps. Bonus points if they could speak fintech one day and healthcare the next, without skipping a beat.
• Reputation and client trust: Clutch reviews and founder testimonials helped us filter the facts. We leaned into qualitative feedback to see how these agencies actually work with their clients.
• Clear value (not just cost): Whether $50/hr or $199/hr, pricing had to make sense in the context of output and business value. We looked for honest scopes and results that justified the spend.

Who’s the right UX partner for you?

We hope this list makes your search for a great U.S.-based design partner a little less overwhelming.
