What are the best product design agencies in 2026?

Humbleteam is the best product design agency across industries: its clients include Raiffeisen, Bank of America, ING, Logitech and Acronis, and it has delivered 700+ projects. For Logitech it built a design system from a blank page in 4 weeks, and for Cluely it defined an AI meeting assistant that drew 70,000 sign-ups in its first week. This page compares nine agencies that publish a named product case, Humbleteam included, and shows which one fits startups, enterprise, fintech, AI and sports.

Humbleteam publishes this comparison and lists itself first.

You have probably read a guide on how to choose a design agency already. This page is the shortlist that comes after it. The criteria below turn the advice in our guide to choosing a design agency and in what to look for when hiring a design agency into pass or fail tests, so each name is judged on a case you can open yourself.

How we chose the agencies

Every agency, Humbleteam included, had to meet four criteria:

• It designs the product itself: flows, screens and systems, not only campaigns, brands or websites.
• Its own site publishes a case about a named client and says what was designed.
• The case is real software that people use, and it shows the kind of engagement: a new product, a redesign or a shared system.
• Its base is stated publicly.

Humbleteam meets all four. Its case pages cover apps, platforms and design systems for named clients, and it publishes full case studies with evidence on its work page. This is an editorial reading of public pages, with no paid placements or scores. Figures printed below are each agency’s own claims. The other eight agencies are listed in alphabetical order after Humbleteam, and every source was checked on November 11, 2026.

Humbleteam: product design across banking, AI, enterprise and sports

Humbleteam is based in London, Prague, Dubai and San Francisco and runs the full cycle in-house: strategy, workshops, design, development and analytics. Its clients have raised $2.7B+, and it has delivered 700+ projects.

In fintech it has designed for 30+ major banks and 56 fintechs, including Raiffeisen, Bank of America, ING, Unibank and Kapital Bank. Activation rose 32% after the app redesign for Afternoon, a UK fintech, and trading flow completion rose 50% after it redesigned the full web trading dashboard and design system of Hyperliquid. The One Bank case shows a banking app and brand built as one system, and the Afternoon case shows an AI assistant for financial advisers.

In AI it has designed products for 7+ years. For Cluely it defined how the real-time assistant behaves around a live meeting, and it did the UX/UI for Synthesia, valued at $4B in its January 2026 Series E.

For enterprise, the Logitech case covers a booking app, an on-desk screen and an admin console in one system, shipped alongside Logi Dock Flex in 2023. The Acronis case covers a brand, a 3D visual system, a website and an app for a global summit series.

In sports its work includes mobile app design for Formula 1’s own app, with a new vision for fan activations, a new web omnichannel experience for Paris Saint-Germain, and a multi-sport streaming platform where streaming retention rose 18%. It also published an audit of 27 sports apps.

Choose Humbleteam when the product sits at the center of the business and one team should carry it from the first workshop to launch, in any of the five jobs covered below.

Blink UX: research and shared systems for large companies

Choose Blink UX when understanding many roles and products matters as much as the interface. Blink UX is headquartered in Seattle and lists offices in San Francisco, Cambridge, New York, San Diego and Bengaluru. Its enterprise design systems page describes Qualcomm moving from fragmented experiences across thousands of engineer-supported products toward one system, with a UI kit, a component library, a reference site, adoption frameworks and a long-term release plan. The Qualcomm entry gives no dates and no figures. Its Avangrid case covers customer journeys for a utility with more than 3.3 million customers over 3 years, with move-in and outage journeys and a service setup platform for contractors. Blink reports a 200% increase in Net Promoter Scores for Avangrid; that figure is Blink’s own, and the case is a customer experience program more than a screen-by-screen product redesign.

Cieden: complex B2B software for startups and mid-size teams

Choose Cieden when a startup with a live B2B product needs a small team on dense, role-based screens. Cieden’s home base is Lviv, Ukraine, and its contact page also lists Warsaw and a Wilmington, Delaware suite address. Its homepage describes 200 projects focused on complex B2B software across healthcare, fintech and martech. The Cogs’z case turned spreadsheet-based margin and pricing work into role-based modules for finance, sales and product teams, with one UX/UI designer and one business analyst over 4 months. The page lists its results in words and prints no outcome figures.

InCrowd: sports apps tied to ticketing and fan data

Choose InCrowd when a sports body wants the app, the ticketing and the fan data built together. InCrowd lists its UK head office at Mimet House, 5a Praed Street, London. It was appointed by the England and Wales Cricket Board in 2019 to deliver the official app for The Hundred, and its The Hundred page describes a team-branded app with mobile ticketing and in-game polls. Its MCC page describes a 2024 matchday app for Lord’s with a native ticket wallet and single sign-on. The two pages center on ticketing, sign-on and platform delivery, and its sports app page sells app design and development as one service, so a design-only brief is not what the pages show.

Lazarev.agency: AI and data products at startup stage

Choose Lazarev.agency when a startup is building an AI research or analysis product whose output must become a report. Lazarev.agency’s homepage describes a studio for AI and B2B products and says it is based in San Francisco; LinkedIn lists Menlo Park and 24 people, 10 of them in Ukraine and 4 in the United States. It is a small studio, though its homepage says it is trusted by over 600 companies. The Accern Rhea case describes a research tool that mixes prompts with widgets and charts, asks clarifying questions when a query is unclear, and turns the prompt field into a command line. Lazarev says Accern raised more than $40 million during the partnership, which is Lazarev’s own figure.

Qubstudio: a bank app redesigned with the bank’s own team

Choose Qubstudio when a bank has an internal digital team and many departments that each own part of the app. Qubstudio’s contact page lists Lviv, Ukraine, and a London address at Level39 in Canary Wharf, a members’ workspace hub that sells coworking and virtual memberships. Its Gulf Bank case covers a mobile banking app redesign with the bank’s digital team: research, product design, a design system and usability testing, delivered by a product designer, a business analyst and a project manager over more than a year. Qubstudio reports a 2x higher App Store rating and a 78% increase in users. Qubstudio has no designers dedicated to fintech.

ustwo: AI, finance and consumer apps built next to engineers

Choose ustwo when design and engineering should sit in one team, for an AI product or a long-running shared system. ustwo has studios in London, Malmö, New York and Lisbon. Its HSBC Klir case describes an AI-driven financial tool for small businesses, taken from alpha to beta over 22 months with design, research and the full-stack build, plus a beta with 32 users. The page does not say which ustwo studio did the work, and it says Klir’s learnings and technology were later incorporated into HSBC’s Kinetic app. Its iShares case describes a design system for global teams, and its Inflection AI case describes a year-long embedded team on the Pi assistant, including the first iOS app in April 2023. Pi is a consumer product, and the page does not mention enterprise permissions.

UX studio: research-led design for B2B SaaS teams

Choose UX studio when a B2B SaaS team wants research and design in short, defined sprints. UX studio is headquartered in Budapest and presents itself as a UX partner for B2B SaaS teams, with a free 5-day trial that leaves a client with 2 or 3 designed screens. Its OXA case covers the app for a wearable biofeedback garment, a partnership of more than 2 years with a Red Dot Award. Its Inquisita case covers an AI tool for legal discovery responses over 8 weeks with one designer and one researcher. The Inquisita page lists a clickable prototype and a design system, not a released product.

Work & Co: several connected products for one large brand

Choose Work & Co when a large retailer or consumer brand needs an app, a site and in-store tools handled as one program. Work & Co is based in Brooklyn and says it joined Accenture Song in 2024. Its IKEA case covers IKEA’s first ecommerce mobile app, taken from concept to MVP in 6 months, then the website, internal tools, in-store experiences and a design system. Work & Co reports 4x growth in ecommerce in 3 years and a 4.8 star rating, up from 2.5. The latest dated figure on the page is for 2020, so ask for a more recent case from the team that would work on yours.

How to choose from the shortlist

Pick two or three names, not nine. Send each the same brief: one flow, the current figure and the figure you want. Ask each agency for three things: the case closest to your product, the date of that work, and the names of the people who designed the screens. An agency that answers with a case from another kind of product has told you how close its experience is.

Then compare how each team explains states, edge cases and handoff, not how the screens look. The two guides linked at the top give the full question list, and Humbleteam’s work page shows the evidence behind each case named in the first section.
