5 Best UI/UX Design Agencies in Mumbai: A Curated Shortlist

Mumbai has one of India's deepest benches of product design studios, so the right choice depends on what you're designing. This shortlist covers five options: ZSpace Labs (the publisher, working remotely) for design delivered alongside engineering, ProCreator for SaaS and enterprise products with flexible engagement models, Yellow Slice for research-first UX and service design, Octet Design Studio for complex B2B and SaaS interfaces, and Ungrammary for fintech and banking products.

ZSpace Labs wrote this article and appears first in it as the publisher's featured entry. That ordering reflects who published the list, not an independent ranking, and we would rather say so plainly than imply otherwise.

Mumbai is India's financial centre. The Reserve Bank of India, BSE and the National Stock Exchange are headquartered here, alongside a large concentration of banks, insurers, brokers and fintech companies. It is also home to much of India's film, television and advertising industry and to many consumer brands.

That mix shapes the design problems Mumbai businesses bring to agencies. Financial products need onboarding and KYC flows that feel trustworthy and stay compliant. Media and consumer products compete for attention on crowded phone screens. Many products serve users who switch between English, Hindi, Marathi and Gujarati, and who range from first-time smartphone users to seasoned traders.

These are patterns that come up repeatedly in finance, media and consumer products, not findings about any particular company:

We started from the companies that appear repeatedly in search results, directories and industry lists for this service in Mumbai, then checked each one's official website to confirm what it actually offers, where it is based and who it works with. We kept companies whose own published services match the brief, and dropped ones whose focus sat elsewhere.

Mumbai searches for UI/UX agencies are dominated by directories and by lists that studios publish about themselves. Several of the companies below publish such lists too. We kept studios with a confirmed Mumbai office and a clearly described research and product design practice. Lollypop Design Studio, which also has a Mumbai office, is covered in our India-wide UI/UX shortlist.

Every company was described against the same criteria:

ZSpace Labs is an independent technology and digital product studio where one team both designs and builds. For UI/UX work that covers user research, flows and wireframes, interactive prototypes, interface design, design systems and UX audits for websites, apps and SaaS products.

Because the designers work alongside the engineers, components are specified with their build in mind and design systems are delivered as code-ready tokens and components. That matters most for products like fintech dashboards and onboarding flows, where small details such as error states, loading states and validation messages decide whether users trust the product.

On location: ZSpace Labs does not have an office in Mumbai. It works with businesses there remotely, with meetings on video calls and work shared in common tools. If face-to-face workshops matter to you, the companies below with Mumbai offices can offer them more easily.

Where it is not the best fit: ZSpace Labs does not publish design case studies or awards, and it is not a specialist research consultancy for large, multi-city research programmes.

Who might consider it: Mumbai startups and product teams who want design and development to move together, without a hand-off between agencies.

ProCreator is a Mumbai-based design agency with offices in Singapore and the USA. Its services include UX research, UI design, prototyping, design systems and AI experience design, along with development.

It focuses on SaaS and enterprise products across fintech, edtech, healthtech, BFSI and ecommerce, and offers subscription, fixed-scope and UX-audit engagements. That flexibility suits teams that need ongoing design capacity rather than a single project.

Official website: procreator.design

Who might consider it: SaaS and enterprise product teams that want continuing design support or a focused UX audit.

Yellow Slice is a Mumbai-based strategic design company that describes itself as having worked for more than 15 years. It offers UX research, digital product design, customer-experience and service design, and brand strategy.

Service design is the distinctive part. For Mumbai businesses such as banks, insurers and retailers, where a customer's journey crosses an app, a website, a branch and a call centre, a research-first studio that designs the whole experience rather than only screens can be the better fit.

Who might consider it: Financial services, retail and consumer businesses whose customer experience crosses digital and physical channels.

Octet Design Studio has offices in Mumbai, Bengaluru and Ahmedabad. It offers user research, UI/UX design, usability testing and UI development.

Its specialism is SaaS, enterprise and B2B products, including fintech, healthtech, logistics and martech. For Mumbai's B2B fintech and enterprise software companies, that experience with dense dashboards and multi-role workflows is directly relevant.

Ungrammary is a Mumbai-based UI/UX design agency. Its services cover digital product and UX/UI design, UX research and usability testing, frontend engineering, visual and motion design, website design and design for AI products.

Its site highlights banking and finance alongside SaaS and enterprise, consumer products, health and sustainability. Its BFSI emphasis is relevant for Mumbai, where many banking and financial products are designed.

Official website: ungrammary.com

Who might consider it: Banks, NBFCs, fintechs and SaaS companies that want a design partner with a stated BFSI focus.

The table below summarises each company's published focus and the related services it lists. It reflects what each company says about itself, checked on its official website, and is not an assessment of quality.

Whichever company you shortlist, these are the things that separate a good fit from a frustrating project:

Ask every shortlisted company the same questions, in writing, so the answers are comparable:

Scope drives cost. The number of flows, the depth of research and whether a design system is included matter more than where the studio is based. See how to choose a UI/UX design agency for what to compare.

UX audit first, if unsure. A focused audit of your most important journey is a low-risk way to test an agency before a full redesign. Read UI design vs UX design to work out which problem you have.

Plan for build. In regulated products, the gap between design and production is where problems creep in. Agree who owns hand-off before design starts.

For SaaS and enterprise teams wanting flexible engagements, ProCreator; for research-first design across digital and physical journeys, Yellow Slice; for complex B2B products, Octet; for banking and fintech products, Ungrammary.

If you want design and engineering from the same team, ZSpace Labs works with Mumbai businesses remotely. Whoever you choose, ask each studio to walk you through one project from research to launch.

Company information in this article was checked on each company's official website on 4 October 2026, with office locations confirmed from public company listings where a homepage did not state them. Services and focus areas change, so confirm current details with each company directly. Figures that companies publish about themselves, such as client or project counts, are deliberately left out because we could not verify them independently. Mumbai office locations were confirmed on each company's official website.
