Best Agencies for UI/UX Redesign and Prototyping in 2026

Design ages faster than we’d like to admit. When you’re building a SaaS product, “pretty outdated” is dangerously close to “quietly bleeding users.” That’s why founders and product teams eventually come to the same realization: It’s time for a redesign.

But not all UX agencies are built for SaaS. Some will wow you with a sleek Figma, only for your devs to say, “We can’t build this.” So, how to choose a UI/UX redesign agency that understands your product, your users, and your roadmap?

To answer that, we’ve analyzed Clutch reviews, real case studies, and looked beyond hype to actual outcomes

In this guide, you’ll find the best agencies for UI/UX redesign and prototyping in 2026, grouped by what they’re good at. Let’s start with the one agency that keeps coming up in founder circles for all the right reasons: Eleken.

1. Eleken

Best overall redesign and prototyping agency for SaaS, data, and AI

Eleken is a dedicated product design agency focused entirely on UI/UX for SaaS. Founded in 2015 and backed by a team of 100+ employees, Eleken specializes in redesigning complex products, especially those in B2B, data, geospatial, AI, and no-code/low-code spaces.

Unlike traditional agencies that split their focus across branding, web, and product work, Eleken is built for one thing: making SaaS products clearer, faster, and easier to use.

Over 200 redesigns. 70+ case studies, a flat pricing model, and turnaround times that often surprise even seasoned PMs. Their clients include: Gamaya, REX, Acadeum, Refera, and Whoosh.

• Services: Redesigns for complex SaaS interfaces, UX audits (churn, usability, accessibility in UX), onboarding flows, dashboard UX and data visualizations, prototyping and user journey design, scalable design systems.
• Collaboration style: A dedicated designer embedded in the team, no PMs in the middle. Communication happens directly via Slack, Loom, Figma, and async comments.
• Pricing: A flat monthly subscription: $5,999/month for a dedicated full-time designer (part-time collaboration also available), no hourly billing or extra fees.

That setup makes Eleken a good fit for early-stage or remote-first SaaS teams who need product improvements without the traditional agency overhead.

Designers also go through an internal 3-month UX bootcamp that covers:

• Accessibility standards.
  
  
• UX design patterns for data-heavy tools.
  
  
• Dev-handoff workflows.
  
  
• UX flow optimization.

Strengths

• SaaS-only focus and deep expertise in geoservices, data, AI, no-code/low-code platforms, and developer-focused UI/UX design.
• Fast turnaround time thanks to async collaboration and focused scope.
• UX audit built-in, with churn analysis, flow mapping, and usability fixes come standard.
• Dev-friendly design handoff with clean Figma files and documented design systems.
• No scope creep or pricing surprises, the subscription covers everything.

Weaknesses

— No in-house development, Eleken focuses strictly on design.
— Not suitable for pure marketing websites or visual brand work.

Proof and results

Eleken’s impact shows up in the measurable results their clients achieved. For example:

• Datawisp raised $3.6M after Eleken redesigned its no-code analytics platform.
  
  
• SEOcrawl grew from 0 to 2,000+ users with Eleken’s UX overhaul.
  
  
• MyInterview fixed a 90% user churn rate after their redesign.
  
  
• Advan Research attracted a new segment of users with a streamlined interface.

Eleken maintains a 4.8 rating on DesignRush, reflecting consistent client satisfaction. One client shared: “We are incredibly pleased with Eleken's work on our web application revamp. They consistently exceeded our expectations, proving to be an invaluable partner. Eleken's team, especially their UI/UX designer, demonstrated exceptional talent and a profound understanding of our vision. Their ability to translate complex requirements into intuitive, aesthetically pleasing, and highly functional designs was truly remarkable…”

Across 111+ Clutch reviews, Eleken holds a 4.9-star rating, with clients repeatedly highlighting their speed, clear thinking, and ability to simplify complexity.

Want to test their approach before committing? Eleken is one of the very few UX agencies that offers a free trial. They'll design 1–2 screens upfront to make sure the fit feels right.

2. Cieden

Best for research-heavy B2B redesigns

Cieden is a UX/UI design agency that’s gained a solid reputation for helping B2B SaaS products solve UX issues through research-first design. 

What sets them apart is their commitment to UX discovery and analysis. Before jumping into wireframes or color palettes, they dig deep into user personas, workflows, and product strategy. 

It’s a great match for companies that need design clarity before scaling, especially if they’re working with dashboards, admin panels, or multi-role systems. Their clients are Sitenna, Lykon, Apollo, etc.

• Services: Full-cycle product design, UX research and discovery, user journey mapping, wireframing and UI design, design system development, product strategy, and feature planning.
• Collaboration style: A traditional agency structure: a dedicated external design team with a project manager, frequent status updates, and structured milestone reviews. Tools: Figma, Miro, Slack, and Notion.
• Pricing: A project-based pricing model, with custom quotes depending on complexity and scope.

The agency works with both startups and established SaaS platforms, particularly in B2B, finance, and enterprise productivity. Clients can expect a strong focus on upfront planning and structured timelines, which is a pro for teams that hate surprises.

Strengths

• Excellent at mapping out complex B2B workflows.
• Strong discovery phase to reduce costly redesigns later.
• Design system creation for scaling design consistency.
• Works well with stakeholder-heavy orgs.

Weaknesses

— Slower to start: discovery takes time (not ideal if you need a prototype next week).
— More formal process: fewer async and flexible touchpoints.

Proof and results

Cieden has worked with platforms in finance, logistics, SaaS, and healthcare, often redesigning legacy interfaces and building modern UX foundations from the ground up.

Their portfolio shows a strong emphasis on structure, clarity, and usability, especially in high-stakes products where one confusing flow = lost revenue.

Their case studies include redesigns that helped simplify overloaded enterprise dashboards, increase activation and user retention, and align design with evolving product UX strategy. Cieden holds a 4.9-star rating on Clutch. 

One of the clients noted: “They knew what they were doing and had a passion for their job, and it showed in the quality of their work.”

3. Work & Co

Best for enterprise-grade platforms

Work & Co is a digital product agency trusted by some of the biggest brands in the world, such as Apple, IKEA, Mercedes-Benz, Google, and other giants you’ve definitely heard of.

They specialize in designing and building large-scale platforms with serious business and technical requirements. Their approach combines sleek UX with full-stack engineering, strategy, and cross-disciplinary teams. If you’re running a redesign for a Fortune 500 product, Work & Co is one of the few agencies built to handle that scale.

That said, you probably don’t call Work & Co unless you have a few million dollars of budget to work with, and a few quarters’ worth of roadmap already locked in.

• Services: Full digital product development, UX/UI design at scale, product strategy and research, custom software development, end-to-end digital transformation projects, native apps, enterprise platforms, and web systems.
• Collaboration style: Embeds their designers, developers, and strategists into client teams. You’ll get weekly standups, detailed status docs, and dedicated teams that scale with your project as it grows.
• Pricing: This is not a budget option; it typically works on long-term retainers or high-budget fixed projects.

Clients are usually mid-market to enterprise-level businesses with internal teams that need external product firepower. The company operates like a product team for hire: design, dev, and strategy all under one roof.

Strengths

• End-to-end service (design + engineering + product strategy).
• Battle-tested with global brands and enterprise UX challenges.
• Great fit for complex replatforming, native apps, or global rollouts.
• Deep internal processes and tight quality control.

Weaknesses

— Pricing makes them inaccessible to most startups.
— Slower timelines due to enterprise scale.
— Not built for quick turnarounds, prototypes, or early MVPs.

Proof and results

Work & Co doesn’t have a Clutch rating, but their impact speaks for itself. They’ve launched flagship apps and platforms that are used by millions of people worldwide.

For example, projects include a complete design overhaul of Virgin America’s booking system and IKEA’s e-commerce platform redesign.

If you’re running a high-visibility, high-budget digital product initiative and need a partner with proven enterprise muscle, Work & Co is about as safe a bet as it gets.

4. Duck.Design

Rebranding and marketing design alternative

Duck.Design is one of the better-known players in the “unlimited design subscription” space. They’re a generalist design agency that covers everything from UI/UX and branding to illustrations, motion graphics, and pitch decks. 

They’re not UX specialists, and they won’t do a full strategy teardown or run usability tests, but if you need solid UI screens or a working prototype turned around quickly, Duck.Design can deliver on a budget.

• Services: UI/UX screens, landing pages, mobile app designs, logos, branding assets, presentations, illustrations, and motion graphics.
• Collaboration style: A ticketing system: you submit a task, and a designer works on it in the order received. You communicate via email or client portal, not embedded Slack-style collaboration. 
• Pricing: Flat subscription starts around $999/month (can vary slightly based on promotions or plans), one task at a time, or multiple tasks with higher-tier plans.

The agency operates on a flexible model if your design needs come in waves, and you’re okay with “good enough” quality for simple flows, decks, or MVPs.

This works best if:

• You have clearly scoped, well-described tasks.
  
  
• You don’t need deep UX thinking or real-time feedback loops.

This makes them a good option for early-stage startups or solo founders who need some design help but can’t commit to high-end agency pricing.

Strengths

• Budget-friendly alternative to design retainers.
• Covers many design types, including marketing, branding, and illustrations.
• Easy to start and stop based on your design volume.
• Great for UX design for startups with tight budgets and a fast turnaround.

Weaknesses

— Not a UX-focused agency.
— No research, audits, or usability and user testing.
— Workflow is task-based, not strategic.
— Dev handoff may lack documentation and design system consistency.

Proof and results

Duck.Design serves a wide variety of clients across industries, namely Samsung, Ventoo, and Skycop. You’ll see everything from landing pages to app screens and pitch decks in their portfolio, and they earned a 4.8 rating on Clutch.

While you won’t find deep-dive case studies or detailed outcome metrics, customer testimonials consistently highlight reliable turnaround, solid UI output, and decent value for the money. Clients admitted: “They combine strong design thinking with an efficient delivery process.”

5. Bilberrry

Best for UX + development combo

Bilberrry is one of the best product redesign agencies that delivers strong UI/UX design and custom software development under the same roof.

They’re a Seattle-based digital agency with a tight-knit team, best known for high-quality product design paired with scalable engineering. That means they fix UX issues, promote tighter collaboration between design and development, and speed up time to launch.

If you’re working on a redesign and your in-house developers are maxed out (or nonexistent), Bilberrry is a strong option to consider.

• Services: UX/UI design for web and mobile products, frontend + backend development (React, Node.js, etc.), full product lifecycle projects, website redesigns, and CMS builds.
• Collaboration style: A mini internal product squad, a designer + developer combo. Project management and communication are tight, often async-friendly.
• Pricing: Custom project-based pricing, depending on scope (redesign only vs. redesign + build), timeline, technical requirements, etc.

The company is not the cheapest, but if you need both design and dev done right, the bundled value often beats hiring two separate vendors.

For teams without dedicated product owners or tech leads, this structure keeps everything moving without you having to manage two teams in parallel. They’re capable of jumping in at any stage, from discovery and wireframes to final code deployment.

Strengths

• Full design + dev execution under one roof.
• Tighter coordination = faster launch and fewer handoff gaps.
• Experience with redesigns, MVPs, and marketing sites.
• Seattle-based, with a strong reputation for communication and quality.

Weaknesses

— Not design-only, if you’re just looking for UX help, this may be overkill.
— Not specialized in SaaS, they work across industries.
— Less cost-flexible than design-only shops.

Proof and results

Bilberrry has redesigned and rebuilt platforms for nonprofits and NGOs, consumer product companies, and tech startups needing MVPs and internal tools. Their clients are DELTA, Harvard Kennedy School, gofundme.org, etc. The company is proud to have a 5 rating on Clutch. 

They don’t publish performance metrics like “activation doubled” or “churn dropped,” but client reviews regularly mention launch speed, implementation quality, and smooth collaboration between design and engineering. 

One of them wrote: “They approached the project not simply as developers, but as partners—invested in understanding our business.”

6. Creative Navy

Best for research-heavy UX and complex interfaces

Creative Navy is a UX/UI design agency based in the UK and Germany, known for its methodical, research-first approach. If you’re building a technically complex product like medical software, automotive systems, or enterprise dashboards, Creative Navy brings the rigor and structure to match.

Their team leans heavily on cognitive science and interface logic, making them a great fit when usability and precision matter more than flashy visuals. They shine in regulated industries or when you need a design for simplicity that turns dense information into a clear, usable interface.

• Services: UX research, interaction design, UI design, user testing, design for embedded systems, medical interfaces, and custom software products.
• Collaboration style: Highly structured. Expect deep research phases, detailed documentation, and a focus on logic-driven design. You’ll work closely with a core team, and communication is clear, if a bit formal.
• Pricing: Higher-end, reflecting their specialized expertise. Not the cheapest option, but ideal when design decisions carry high technical or business risk.

The agency works across sectors, including healthcare, automotive, education, and embedded technology.

Strengths

• Strong UX research and validation processes.
  
  
• Especially effective for high-stakes, data-heavy products.
  
  
• Experienced in designing regulated or technical systems.

Weaknesses

— Less focus on rapid iteration or startup-style speed.
— May be overkill for simpler marketing websites or MVPs.
— Not ideal if you want a highly visual or marketing-led design.

Proof and results

Creative Navy’s portfolio includes work for Jaguar, Ford, Philips, and the NHS, often involving critical tools and real-world applications. Their case studies focus on usability, system clarity, and decision-making logic.

While they don't publish flashy ROI stats, clients highlight their reliability, attention to detail, and ability to untangle complexity through smart UX. Their Clutch rating is 5, based on praise for thorough research and high-quality execution.

Their clients noted: “Right from the introductory round, Creative Navy impressed us with their analytical and process-oriented approach.”

7. Awesome NYC

Best for startup-focused prototyping

Awesome NYC is a small design studio based in New York City, best known for helping startups translate early-stage ideas into clear, pitch-ready prototypes.

Their sweet spot is the overlap between design thinking and storytelling, ideal if you're fundraising, launching an MVP, or trying to validate a new product direction fast.

Unlike larger UI/UX prototyping agencies that might bury you in process, Awesome keeps things scrappy, hands-on, and startup-friendly. Think of them as a design partner that helps you sharpen your product narrative and your UX.

• Services: Rapid prototyping for MVPs, UX/UI redesign for web and mobile apps, pitch deck design and storytelling, light product strategy and flow planning, design sprints.
• Collaboration style: An extension of your founding team. You’ll collaborate directly with a lead designer or creative director. Expect lots of Loom videos, async feedback loops, and real-time iterations in Figma.
• Pricing: Customized per project, with a focus on shorter, high-impact engagements. 

Awesome NYC is not the cheapest agency around, but they strike a good balance between affordability and design maturity. 

Their goal is to help you move quickly while making sure what you're building makes sense to users and investors. They often start engagements with a short-term design sprint, which makes them a low-risk, high-speed partner for startups in motion.

Strengths

• Fast, founder-friendly prototyping.
• Great for early-stage UX and investor decks.
• High-touch collaboration without agency bloat.
• Combines design with storytelling and clarity.

Weaknesses

— Not ideal for long-term design support or complex SaaS redesigns.
— Limited scalability; they’re a small studio.
— May need additional UX validation for production use.

Proof and results

Awesome NYC’s portfolio includes a range of early-stage product launches, pitch-ready MVPs, and startup websites, all built with a strong narrative and user flow in mind. The clients are Kisi, Udemy, PREQL, and more. 

The company doesn’t have a Clutch rating, but they've helped clients clarify product concepts pre-launch, impress VCs with better user flows, decks, and prototype features that later became the foundation of their product roadmap. On the Awesome NYC website, clients share that they “go with the flow and deliver results quickly…”

8. Obys 

Best for visual creativity in redesigns

If your goal is to stop people mid-scroll and make them say, “Whoa, who designed this?”, Obys is likely behind one of those moments.

Obys is a Ukrainian creative studio that’s built a cult following for its visually striking, highly experimental web design. While they’re not focused on UX in the traditional SaaS sense, they excel at brand-forward redesigns, especially for teams looking to break away from the safe, flat design mold.

If your product is content-driven, design-led, or in a creative industry (fashion, design, media), Obys brings the visual punch that most UX agencies simply can’t.

• Services: Website redesigns, UI animation and motion design, brand storytelling through interactive design, and visual identity alignment.
• Collaboration style: A creative collaboration with regular Figma updates and stakeholder reviews. This is not an embedded designer or async model; it’s closer to working with an art director.
• Pricing: Project-based pricing, usually in the mid-to-high range. Not cheap, but justified by the level of craft and originality.
  
  

If you’re looking for high-conversion landing pages or modern marketing sites, this is where your money turns into brand equity. You can expect moodboards and concept directions early on and deep involvement in visual language, layout, and animations.

They’re best suited for marketing sites, creative portfolios, agencies, and high-concept startups looking to make a memorable visual statement.

Strengths

• Bold, memorable visuals. Obys' work regularly wins design awards.
• Animation and motion design are first-rate.
• Great for brand-forward product storytelling.
• Strong fit for high-impact redesigns of public-facing pages.

Weaknesses

— Not focused on product UX or dashboard flows.
— Limited value for functional redesigns or dev-ready Figma handoff.
— May prioritize visual aesthetics over usability (by design).

Proof and results

Obys has received recognition from Awwwards, CSS Design Awards, and Behance for its work. Their projects are often what users remember about the brand. 

If you’re redesigning a homepage, building a microsite for a product launch, or creating a new brand identity through digital design, then Obys will make your product unforgettable. 

Obys’s rating on Clutch is 5, based on one review.

This client shared: “It’s a large amount of talent and creativity concentrated in such a small company.”

Big Human brings a balanced, full-service product design approach to every engagement.

10. DesignStudio 

Best for global rebrands with product UX

DesignStudio is among the top user experience redesign firms and a global creative powerhouse that helps brands evolve their identity and product experience in parallel.

• Proven with global brands and high-growth scale-ups. 
• Ideal for rebrands, relaunches, and positioning shifts

This client wrote: “It’s been four years since we worked together, but we still use the general framework they gave us.”

Comparison of the best UI/UX redesign agencies 2026 

Choosing the right design partner can be challenging. This comparison table highlights top UI/UX redesign companies, including details on their strengths, pricing models, and ideal use cases to help you make an informed decision.

What makes a great redesign agency, and which agency should you choose?

Based on our experience, here’s what separates agencies that drive real product growth from those that simply deliver “nice-looking” Figma files:

1. They improve real product outcomes. A good redesign performs better. Think: higher activation, lower dropoff, faster time-to-value. Bad UX examples? Slow onboarding, confusing flows, and features no one uses. Great agencies fix that.
   
   
2. They hand off designs your devs can build: Scalable components, clear documentation, developer collaboration throughout the process, not just at the end.
   
   
3. They specialize in your product type. A SaaS dashboard isn’t the same as an e-commerce app or a marketing site. Great agencies know your space and bring relevant, proven experience, rather than bad design.
   
   
4. They move at the right pace. Whether you're in prototype mode or post-Series A, the right agency matches your speed, stage, and scope.
   
   
5. They simplify complexity. If your messy flows turn into clean, intuitive UX, you’re in good hands. If you're still staring at chaos a month in, something's off.
   
   
6. They don’t just listen; they think like product people. Great agencies ask hard questions, challenge assumptions, and act like an embedded product team, not just outsourced designers.

So, which agency should you choose?

If you’re building a SaaS product, and you want:

• Clear, usable UX your users actually understand.
  
  
• Dev-ready Figma files your engineers will appreciate.
  
  
• Fast, embedded designers, without full agency overhead.
  
  
• Real outcomes like better onboarding, higher activation, and improved retention.
