A real product redesign changes the underlying structure — navigation, information architecture, task flow — not just the visual layer on top of it. Most teams can't tell which one they actually need. The quadrant below sorts it in two questions; six named redesign specialists are profiled after it, alongside NetBramha's HDFC Bank case at 60M+ users.
HDFC Bank — 60M+ users, zero new visual components
HDFC Bank's mobile app served an enormous, varied user base — from first-time digital banking users to power users managing multiple accounts and products. It looked reasonably current; users were still getting lost. NetBramha's redesign rebuilt the app's structure around user tasks rather than the bank's internal product lines — a change invisible in a single screenshot but decisive at the scale of 60M+ users.
Proven at national banking scale with zero visual-language changes needed.
Not a visual-refresh specialist — best fit is genuinely structural work.
Enterprise-scale, undisclosed pricing
IDEO appears in independent research on firms that perform B2B UX redesign at the largest scale — organisation-wide transformation rather than a single product surface. Fit for a redesign that's really a business-model or org-structure question wearing a UI problem's clothes.
Systemic scope few others match.
Not for a single-product redesign on a normal timeline/budget.
Part of Capgemini Invent
frog applies creativity, strategy, design, and data to reinvent businesses — a redesign practice that treats the interface as one output of a larger strategic reinvention rather than an isolated deliverable.
Strategy-plus-design redesign scope.
Consultancy-scale engagement — confirm budget fit.
1,000+ design professionals within Accenture Song
Fjord's strength is redesigning customer experiences that cross multiple channels at once — mobile app, web, contact centre, physical branch — rather than a single-surface product redesign. Relevant when the "product" being redesigned actually spans several disconnected touchpoints.
Multi-channel scope beyond a single app or site.
Overkill for a single-product structural redesign.
10+ years focused specifically on application redesign
Fuselab Creative has spent over a decade doing application redesign work specifically — one of the few names on this list where redesign is the stated specialism rather than one service among many.
Redesign-specific specialism, not a general practice offering it as an add-on.
Ask for scale references — less publicly documented at enterprise-banking volume.
Publishes its own app-redesign methodology
Excited publishes its own "UX to UI" app redesign process with a worked case study — useful specifically if you want to see the methodology before committing, rather than taking positioning claims on faith.
Transparent, published process before you sign anything.
Single published case — ask for more before assuming broad scale experience.
Plot your product on two axes: can users already find what they need? and does the product look current? The quadrant tells you which engagement to scope.
