UI/UX design companies: 9 to compare and how to choose one

Below are nine UI/UX design companies, or agencies, to compare: Ronas IT, Clay, Eleken, Fuselab Creative, UX studio, Ramotion, Fuzzy Math, Neuron, and Phenomenon Studio. Choose by what you can check: shipped products like yours, the people who will do the work, and how the designs reach your developers.

What does a UI/UX design company do?

It turns a product idea, or a product that already exists, into screens people can use without help and into files developers can build from. The UX part decides the flows: what a user does, in what order, and what happens when something goes wrong. The UI part decides how each screen looks. A typical project covers five kinds of work.

• Research: interviews with users, a review of analytics, or a review of the current product, to find where people get stuck.
• Flows and wireframes: each task drawn as a chain of simple screens before any visual design starts.
• Prototype: clickable screens that you and test users can try before anyone writes code.
• Visual design and a design system: the final screens plus a library of reusable components, such as buttons, forms, and tables.
• Handoff: organized design files, notes on how each screen behaves, and answers to developer questions during the build.

Some companies stop at design and give the files to your developers. Others also build the product, so one company is responsible for both the design and the code. The table below shows which is which.

9 UI/UX design companies to compare

Each company here designs apps, web products, or SaaS software for clients, not only marketing sites or brand identities. The facts in the table come from each company's own website, where you can check them before your first call.

Ronas IT comes first because this is our own blog; the order of the other eight means nothing. Review scores are not listed: they change over time, and each company's Clutch profile shows the current ones. Weak points are not listed either: as a competitor, we would not be a neutral judge, so each entry ends with the kind of project it fits.

1. Ronas IT

We provide UI/UX design services for mobile, web, desktop, and tablet apps, and we can build the product once the design is approved. Our designers and front-end developers work with each other directly. Work usually runs in sprints of one to three weeks, and you can check the result of each sprint yourself, for example new screens in the mockups. You hear about each design change when it happens, because a small edit in a mockup can mean extra development work. Each project's design file starts as a copy of our own design system, restyled for your product, so the components, spacing, and colors stay consistent across the screens.

For Hamperapp, a laundry and dry cleaning service from Florida, we started from user flows and wireframes and then designed and developed its four interfaces. Our design projects show the interfaces we have drawn for different industries.

Worth a call if: you want one team to design the product and then build it.

2. Clay

Clay is based in San Francisco and lists 78 team members. It started as a UX design agency for mobile apps and enterprise and SaaS software, then added branding and marketing websites, and it has its own web and app developers. The clients named on its site include Coinbase, Uber, and MoneyLion among startups, and ADP, Amazon, VMware, and Cisco among enterprise companies. It works on time and materials (you pay for the hours spent), a fixed fee, or a retainer (a regular fee for ongoing work).

Worth a call if: the product is enterprise or SaaS software and you want to pick one of the three payment options above.

3. Eleken

Eleken is a design team from Kyiv, Ukraine, founded in 2015, and it works only with SaaS companies. It sells designers by the month: a part-time designer costs $4,599 a month, a full-time designer $6,599, and two full-time designers $11,999, with a two-month minimum contract. You talk to your designer directly, without a project manager in between. Eleken does not write code; it prepares the designs for your developers.

Worth a call if: a SaaS company that already has developers needs a designer on the team soon.

4. Fuselab Creative

Fuselab Creative was founded in 2017, is based in McLean, Virginia, and designs dashboards, data visualizations, and AI interfaces for enterprise clients and regulated industries such as healthcare, finance, and government. It also offers development. Its site names NASA, Fiserv, Uber, and NIH among its clients. Each project gets a fixed-price proposal after a call about the scope, and the work ends with a Figma design system your team can extend. The smallest package of Fuselab's MVP service, for the first version of a product, is a clickable prototype for $14,999, ready in 2 weeks.

Worth a call if: your product shows dense data, or it must meet healthcare requirements or US federal accessibility rules.

5. UX studio

UX studio has its headquarters in Budapest, Hungary, and was established in 2013. It focuses on B2B SaaS and starts from research: its researchers talk to your end users, and it can place a designer or a researcher inside your team. It also has a development team that builds what it designs.

Worth a call if: you need user research to decide what to fix in a complex B2B product.

6. Ramotion

Ramotion is based in San Francisco and has been in the industry since 2009. It designs brands, websites, and apps and also does frontend and backend development. Its site describes an Apple TV app interface for NBCUniversal and design work for Cellebrite since 2018.

Ramotion usually puts 5 to 12 team members on a project, depending on the scope. For app design, it sets a minimum project price of $50,000 and offers a $35,000 discovery sprint to run first.

Worth a call if: your product launch also needs a brand identity and a marketing website.

7. Fuzzy Math

Fuzzy Math has worked on user experience design and strategy since 2009 and has offices in Chicago and Toronto. It focuses on B2B and enterprise software. Besides UI/UX design and research, it helps companies set up their own UX teams through organization design, training, and hiring. On the development side, it offers front-end development, production-ready HTML and CSS, and support for your developers during implementation, not the full product build.

Worth a call if: setting up an in-house design team is your next step, and you want help with it.

8. Neuron

Neuron is a San Francisco-based UX/UI design agency for enterprise products and also lists an office in New York. It calls itself a boutique agency, and its site says the team has deep knowledge of B2B software, especially in finance, AI, project management, and analytics. Besides research, design systems, and usability testing, it offers front-end development support from its UX engineers.

Worth a call if: a product team with its own engineers wants designers who can also help with front-end work.

9. Phenomenon Studio

Phenomenon Studio was established in 2019, and its team of 70+ works from Canada, the US, Ukraine, Poland, Estonia, and Switzerland. It covers product strategy, UI/UX design, and web and mobile development, with projects in healthcare, SaaS, fintech, and edtech. Its prices start at $8,000 for mobile app design and $12,000 for web app design.

Worth a call if: one team should cover strategy, design, and development, with people in both North America and Europe.

How to choose a UI/UX design company

Shortlist three or four companies whose focus matches your product, then judge them on work you can inspect, not on how their own website looks. Send all of them the same one-page brief: what the product does, who uses it, which platforms it needs, and whether you have developers. Then compare the answers to the questions below.

• Shipped products: concept shots, designs made only for a portfolio, show visual skill; a shipped product shows how the team dealt with real users and real technical limits. Ask which portfolio items are live and what the company did on each.
• Your kind of product: a dashboard with many user roles and a consumer app with one main task need different skills. Look for work with a similar number of roles, screens, and rules.
• Whole flows: a flow is the full path through one task, such as sign-up or checkout, screen by screen. Ask the company to walk you through one from a shipped product.

“A whole flow tells me more than any single screen, because it has to include the screens nobody posts: the search with no results, the declined card, the form with an error. When those get the same care as the main screen, developers do not have to invent them, and the finished product looks like its design.”

Elizaveta Denisova, Lead Designer at Ronas IT

• The people: find out who will design your product and whether the same people stay on it until the end.
• Research and testing: ask what research and user testing the price includes; if the answer is none, ask what the company will base its design decisions on. Ours rest on the product map of roles and features, a review of competing products, and what you know about your users. Sessions with real users are run by your team and are not part of our design price.
• Quality control: ask who checks a screen before you see it. At Ronas IT, the designer first goes through a written quality checklist, and then another designer reviews the work and sends it back with comments if something needs fixing.
• AI in the design work: ask where the company uses AI and who reviews what it produces. Our designers use AI for a fast first draft of routine interfaces and then choose a direction and finish the screens themselves.
• Handoff: before you sign, agree on what your developers will get with the designs: a component library, notes on how each screen behaves, time for their questions during the build, and what their AI coding tools will receive to keep the style. With every handoff we add a DESIGN.md file to your code repository that describes the colors, fonts, and spacing for coding agents.

“I judge a handoff by the questions my developers still have after it. After a good one, they ask about the product, not about what the designer meant.”

Alexander Storozhevsky, Lead Developer at Ronas IT

• Changes: ask how you and your developers will hear about a design change, and when a comment in the design file counts as resolved.
• References: ask for two past clients you can call.

How UI/UX design companies price their work

Most companies price design in one of three ways: by the hour, as a fixed price for an agreed scope, or as a monthly fee for a designer or a team. Clay offers all three, Eleken sells designers by the month, and Fuselab Creative gives each project a fixed price. The model matters less than what the price includes, so ask each company to list the research, prototypes, design system, and handoff support in its proposal.

At Ronas IT, design work is priced by the result you get, never by the hour:

• UX audit: from $500, from 3 days: we walk through the key flows of your app or the key pages of your site and hand you the problems ranked by how much they hurt users and conversion, each with a fix to make.
• Design concept and UI kit: from $1,000, from 3 days: one or two screens that set the look of the product, plus the UI kit, the set of ready interface components, from which your team or ours draws the remaining screens.
• Design of a new product: from $2,000, at least 1 week: the flows, the concept, the UI kit, and every screen, with revisions inside the agreed scope at each stage. The price follows the number of screens and their complexity, whether the product is a web app or a mobile app.
• Product redesign: from $2,500, at least 1 week, for a product that already exists: a check of the current design and usability comes first, then the key screens change and the rest get a UI kit, while your key features and brand are kept.
• Website design: from $800 for a landing page and from $1,500 for a corporate site or an online store, with responsive layouts of the key pages handed over in Figma.

These prices are for design without development, and project management is part of each of them. Our guide to UI/UX design cost shows how user roles, platforms, and research change the price, and how to calculate your budget.

What to do next

1. Write the one-page brief: the product, its users, its platforms, and whether you have developers.
2. Pick three or four companies from the table whose focus matches your brief; if you have no developers, favor the ones that also build.
3. Send each the same brief and ask for one whole flow from a shipped product and a list of what the price includes.
4. Call two past clients of the company you like most before you sign.

Send us your brief, and we will reply with our questions about the scope and an estimate for the design.
