Redesign is harder than new design. You’re not starting with a blank canvas — you’re working with an existing product that has existing users, existing habits, existing technical constraints, and existing stakeholders who have opinions about every decision.
The agencies that do redesign well understand this. They don’t treat it as a design problem alone. They treat it as a design-plus-change-management problem, where the quality of the design work and the quality of the transition are both necessary conditions for a successful outcome.
1. Linkup ST
Location: New York, NY
Focus: UI/UX Redesign, Conversion Optimization, Ongoing Design Partnership
Redesign engagements at Linkup ST start with a question most agencies don’t ask clearly enough: what are we actually trying to change, and what does success look like when we’ve changed it? Their OKR-driven methodology makes that question structural — before any design decisions are made, the team defines the objectives, the metrics that will reflect progress toward those objectives, and the design decisions that are most likely to affect those metrics.
For redesign specifically, this framework provides something valuable: a clear basis for prioritizing what to change. Not “everything that can be improved” but “the things that affect the outcomes we care about most.” That prioritization discipline is what separates redesigns that move metrics from ones that produce a better-looking version of the same performance.
The Emotional-Functional Framework also addresses the user transition challenge. Behavioral level: how do we make the new interface learnable without alienating experienced users? Reflective level: does the redesign feel like an improvement to existing users, or like a disruption? These are design questions with real stakes in a redesign context — getting them wrong produces user backlash regardless of how objectively better the design is.
Their validation process — prototype testing of key user flows before handoff — is particularly valuable in redesign, where the cost of getting something wrong in a shipped product is higher than in new product development.
11+ years of experience, 40+ global awards, and a track record that includes products reaching 70M+ users. The Performance model is worth noting for redesign specifically: ongoing monthly engagement that continues through and after implementation, ensuring the redesign achieves its intended outcomes rather than just shipping.
Best for: Companies undertaking significant product redesign with clear business outcome requirements
Key differentiator: OKR-driven redesign methodology with prototype validation before handoff
2. Work & Co
Location: Brooklyn, NY
Focus: Digital product redesign and development
Work & Co has done some of the most notable digital product redesigns in the market — Delta Air Lines’ digital experience, Apple TV’s interface, major e-commerce platform redesigns. Their commitment to staying involved through implementation means redesigns actually ship the way they were designed.
3. Ustwo
Location: London / New York
Focus: Product redesign and innovation
Ustwo approaches redesign from a strategy-first position — they want to understand why the current design isn’t working before proposing what to change. Their engagement process is deliberately upstream-heavy, which produces redesigns that address root causes rather than surface symptoms.
4. Adaptive Path
Location: San Francisco, CA
Focus: Experience redesign, service design
Adaptive Path’s strength in redesign is in the research and strategy layer — understanding the current experience’s failure modes before defining what the redesign should accomplish. Strong for complex experience redesigns that span multiple channels and touchpoints.
5. Huge
Location: New York, NY
Focus: Large-scale digital experience redesign
Huge has the scale to handle enterprise redesigns that span multiple products, channels, and business units. For organizations undertaking large-scale digital transformation rather than single-product redesigns, their organizational capability matters.
6. Ramotion
Location: San Francisco, CA
Focus: Brand and product redesign for tech companies
Ramotion has built a strong reputation for tech company redesigns — particularly where brand identity and product design need to be realigned simultaneously. For companies whose product redesign is happening alongside a brand evolution, their combined capability is relevant.
7. Clay
Location: San Francisco, CA
Focus: UI/UX and visual redesign for technology companies
Clay produces some of the highest-quality visual redesign work in the market. Their client list includes major tech companies that needed their products to feel more premium and trustworthy. Strong for redesigns where the visual and brand layer is the primary focus.
8. Unfold
Location: New York, NY
Focus: B2B SaaS redesign
Unfold focuses specifically on B2B SaaS redesign — they understand the particular constraints of redesigning enterprise products: managing the transition for existing users, maintaining feature availability through the redesign, working within technical constraints that come with mature product codebases.
9. Designli
Location: Greenville, SC
Focus: Product redesign and development
Designli’s combined design-and-development capability is particularly relevant for redesign — they can manage the design and implementation of a redesign as a single engagement, reducing the handoff friction that causes redesigns to lose fidelity between design and shipped product.
10. Momentum Design Lab
Location: San Jose, CA
Focus: Enterprise product redesign
Momentum has specific experience in enterprise product redesign — the particular challenge of redesigning products that large organizations depend on daily. Their change management awareness alongside design capability makes them relevant for redesigns where user adoption of the new design is as much a challenge as the design itself.
Final Thoughts
Redesign projects fail more often than they should — not because the design work is bad, but because the problem was defined wrong at the start. Teams commit to redesigning the interface when the real issue is information architecture. Or they redesign the whole product when two specific flows were causing most of the friction. Or they ship something objectively better that existing users reject because the transition wasn’t managed.
The agencies on this list have worked through enough redesigns to know where those failure modes live. That experience is what you’re actually paying for — not just the ability to produce polished design work, but the judgment to avoid the mistakes that make redesigns expensive and inconclusive.
If you’re not yet certain what needs to change — if the symptoms are clear but the causes aren’t — that’s a diagnostic problem before it’s a design problem. UX consulting focused specifically on understanding what’s broken and why is often the right first step before committing to a full redesign engagement.
