Best B2B Product Design Agencies (2026)
Short answer
IBM iX is best for global companies that want B2B commerce and dealer platforms designed and built inside a global consulting program. Isadora Agency is the pick for B2B teams at mid-market and enterprise companies that want customer portals and internal tools their customers and staff use daily, with senior designers bringing product design and web design together. Think Company fits organizations replacing an aging platform whose business rules were never written down.
A B2B product answers to two groups. The company that buys it weighs cost and fit with its existing systems, and the people who open it every morning, from distributors placing orders to sales reps building quotes, care whether it saves them time.
The eight firms here run from IBM's global experience design arm, a large-scale firm that takes on far bigger programs than a boutique would, to small independent studios. Each shows B2B product work on its own website.

How we compared them
Four points shaped the comparison: B2B product work it has shipped and written up, research with people who use the product at work, design handed to engineers as a buildable system, and an engagement model that suits a business-software buyer. The methodology page explains each criterion.
The full list

Product work: A national commercial real estate company needed to replace an aging leasing platform used by national retailers and first-time small business owners. Think Company's research turned leasing rules that lived only in employees' heads into one documented source, then shaped a map-based search for first-time tenants and a design system that scales to a large portfolio. Read the case
Clients: A national commercial real estate company, A global shipping and logistics operator, Penn Mutual
Engagement: Working since 2007. Short fixed-scope sprints are available.
Not the right fit when: A quick visual refresh is the whole brief; Think Company's cases begin with research into how the business works.
DOOR3
Best for: Companies modernizing information products and sales software for several user groups, with UX and engineering together
DOOR3 is an independent technology consultancy and software firm founded in 2002 and headquartered in New York City. Its design practice covers UI design, design systems, UX audits and research.
Product work: Geofacets, a geoscience database run by a science and health information company, had kept the same interface for years while its content grew. DOOR3 interviewed academic researchers, corporate engineers and executives one on one, ranked the features and wireframed the priorities. The redesign simplified the main view, added persona-based views and saved lists, and brought spatial search forward. Read the case
Clients: Geofacets, Ansell, Cadwalader
Engagement: Founded 2002. Minimum not published.
Not the right fit when: The team wants design files only; DOOR3 pairs UX with software development and often runs the build.
Viget
Best for: Software companies whose enterprise product needs a visual overhaul, new data views and a design system
Viget plans, designs and builds digital products and platforms from four US offices, Boulder and Durham among them. Its design work spans product design, UX and UI, design systems and AI interfaces.
Product work: AppOmni helps security and IT teams protect large estates of third-party software, and as competition grew, the product's design needed to match its technology. Viget delivered an aesthetic overhaul and new features for data visualization, collaboration and issue prioritization, including one workspace where teams monitor threats and investigate outliers together, plus a design system for future features. Read the case
Clients: AppOmni, Stern Pinball, A national parks nonprofit
Engagement: Minimum not published.
Not the right fit when: The main need is field research into an undocumented process; Viget's enterprise case centers on visual redesign.
Fuzzy Math
Best for: B2B software companies that want field research with every level of user before a complex platform is redesigned
Fuzzy Math is a user experience design, strategy and innovation consultancy based in Chicago and Toronto. It keeps a small, stable client roster and works across enterprise and B2B business applications.
Product work: VelocityEHS makes chemical safety software used by everyone from senior safety managers to entry-level workers. Fuzzy Math sat in on onboarding meetings and support calls, embedded with the company for two full days and watched people use the product in warehouses. That research shaped a new information structure, navigation patterns and one visual language across devices. Read the case
Clients: VelocityEHS, Availity, Clarix
Engagement: Working since 2009. Minimum not published.
Not the right fit when: The platform also has to be engineered; Fuzzy Math's service list stops at UX strategy, research and UI design.
Creative Navy
Best for: Makers of technical software that has to stay exact for experts while opening up to newer users
Creative Navy is a London design agency for digital products whose team pairs designers with cognitive scientists. Much of its published work is professional software and embedded interfaces for industry.
Product work: Gexcon's software simulates fires and explosions for industrial safety work, and newer engineers were drifting to simpler tools as its original experts retired. Creative Navy's team learned the software themselves, documented its tasks and tested interface options with users and engineers, then delivered the interaction architecture, prototypes, light and dark UI and a design system. Read the case
Clients: Gexcon, A banking fraud-detection platform, An outboard engine maker
Engagement: Minimum not published.
Not the right fit when: The product is a simple app for occasional users; Creative Navy's work leans toward dense expert tools.
Sidebench
Best for: Founding teams launching the first version of a business tool for outside users and internal staff
Sidebench is a UX design, mobile app and custom software development company working on complex systems integration across the US. Its industries include healthcare, government, finance and B2B SaaS.
Product work: WorkGrades, a web platform that makes giving job references simpler, was started by veteran staffing and recruiting executives. Sidebench helped them put the product vision into words, then designed and developed the minimum viable product, which serves job seekers and works as an internal tool for recruiting teams and hiring managers. Read the case
Clients: WorkGrades, Imagine Impact, Peer Health Exchange
Engagement: Minimum not published.
Not the right fit when: A product with an established user base needs a research-led redesign; Sidebench's B2B case is a first version.
How to choose
Who the product serves is the first split. Some B2B products face customers, such as ordering platforms and client portals; others face employees, such as sales apps and knowledge hubs.
Domain knowledge carries more weight in B2B work than in consumer apps. A leasing platform or an engineering simulator runs on industry rules that users know and outside designers don't, and the stronger case studies show time spent inside the client's operations.
The person who signs for a B2B product often isn't the person who uses it. A procurement lead weighs security and integration; a sales rep wants speed on a busy day. Research with both groups produces a product that clears the purchase review and still gets used.
Integration sets how much engineering the design needs. A firm that also builds can carry an ERP-connected product to launch, and design-only studios hand prototypes and specifications to the client's developers.
What it costs
Most firms here quote each B2B project after a scoping call. Integration raises the figure: a product that reads from an ERP or has to work offline takes more design and engineering time than a standalone web app.
A global consulting group prices design inside a wider platform program, while smaller firms tend to price a defined phase or a first release they'll design and build.
Frequently asked questions
What does a B2B product design agency do?
It designs software that businesses use, from customer portals and quoting tools to dashboards and internal apps. The work usually covers user research, information structure, interface design and a design system, and some firms build the product too.
How is B2B product design different from designing a consumer app?
B2B users often spend hours a day in the product and know their field in depth, so speed and accuracy count for more than novelty, and the product usually has to fit systems the company already runs.
Should internal tools get the same design attention as customer-facing products?
Employees can't switch tools, but they can work around a poor one with spreadsheets and email. Isadora Agency's benefits hub for News Corp replaced eight separate websites with one site where employees pick their employer, then a topic.
How long does a B2B product design project take?
Redesigning a single tool can take a few months. A new platform with research across several user groups runs longer, and some engagements continue through later releases, as Isadora Agency's multi-year product design partnership with Brookfield Residential has.
Which agency suits a B2B company that needs customer-facing and internal tools designed together?
Isadora Agency is strongest for B2B teams at mid-market and enterprise companies that want the tools their customers and their own teams use designed as one system. For Palm Bay International, it designed a resource library and an offline sales app that share the same content.
