Best Startup UI/UX Design Agencies (2026)

Eleken, founded in 2015, is a distributed design team from Kyiv that works only on SaaS products and sells design as a monthly subscription. Each client gets a dedicated designer who talks to the founder or product team directly, with no project manager in the middle, while UI and UX leads and a head of design review the work. New designers complete a three-month UX training program before taking on clients. The case library includes a redesign for Datawisp, a no-code data analysis platform, at seed stage, MVP design for Floret and for the caregiving product FlourishON, and work on Bering Lab's translation tool ahead of its pre-Series A round. The site lists complex B2B, AI, data, geospatial and low-code apps as specialties, and new clients start with a three-day free trial.

Andrew Wilkinson started MetaLab in 2006, and the studio, which concentrates on product and interface design, now belongs to his holding company, Tiny. Its work page presents a range from startups to Fortune 500 clients, and several of its startup cases begin before a product exists. Bardeen, an AI automation startup, came to MetaLab in its early days to conceive and design its first MVP. The studio worked with Otter while the company was still called AISense, shaped the brand and product for PlayerZero, and conceived a financial management startup from the ground up with its founding team. It also delivered an MVP and product roadmap for a back-office platform serving the creator economy. MetaLab has 160 people.

Lazarev.agency dates from 2015 and designs products for AI-native B2B platforms. The homepage pitch to startups speaks to growth-stage companies, Series A and above, where one designer is still carrying the whole product, and offers to step in as an extended design team that firms up the flows and produces a marketing site and an investor-ready demo. The case list spans stages, from the pre-seed AI marketing platform Fieldstream to a website redesign for the logistics company Nimble at Series C. Research and usability testing are available as standalone services, sites are built in Webflow, and the team has 40+ members. Webby recognition runs from Accern in 2024 to Elva in 2026.

Cieden was founded by the siblings Yuriy Mykhasyak and Iryna Serednia and has a team of 50 that has delivered 200 projects, working remotely with clients across time zones. Its focus is complex software: B2B SaaS products from MVP to scale, AI-native products such as copilots and conversational interfaces, and internal enterprise tools. Startup work on its SaaS page includes a redesign for Sitenna, a Y Combinator-backed B2B SaaS company in the UK, and product design for Gridics, a real estate tech startup. Cieden also redesigned the account-based marketing MVP of RevvedUp so it could scale. It publishes prices, including a two-week design sprint in which prototypes are tested with real users.

Halo Lab is a design and development studio with 120 full-time professionals and 500+ completed projects over 13 years. It runs separate design, development and marketing teams, and its services move from a product discovery phase of one to two weeks through SaaS and mobile app design, MVP development and AI integration, with a dedicated startup web design page alongside. For Ahlya, a cycle-syncing wellness app created by a solo founder in the UK, Halo Lab took the product from concept and competitor research through UX architecture, a UI design system and a React Native build to release on the App Store and Google Play. The founder and CEO of Relocate Now is quoted on the site about the custom UX/UI it designed for the company's software.

thoughtbot runs small teams of designers and developers who work closely with clients, and its about page sorts them by product stage: early-stage validation and product strategy, design and build for a complex MVP or first version, and team and process improvement as a product scales. The Joydrive case follows that order. A product design sprint and expert interviews tested the online car-buying business model before any code was written, an MVP followed, and thoughtbot then acted as Joydrive's CTO partner through its Super Bowl commercial launch. The product design practice lists market and customer validation, user interviews and shaping sprints, and its designers also work on finance and insurance products. The company publishes its Playbook and Handbook, which set out how it builds web and mobile products.

Arounda has designed digital products since 2016, and its site counts 500+ businesses served and 50+ team members. Its portfolio is sorted by industry, with fintech, healthcare, Web3, SaaS and AI as the main groups, and many of its cases pair branding with UI/UX. For FundedIQ, a prop trading platform based in the UAE, Arounda ran discovery and competitor analysis, then delivered brand identity, graphic design and UI/UX as one visual system across the product, landing page, social media and print. For Piko Health in Portugal, it designed the brand, landing page and web app, using simple indicators in place of dense data displays. The portfolio also includes pitch deck work, and the about page quotes founders of MYSO Finance and BehindTitles.
