Why choose our product design agency?

  1. Increase Adoption and Retention

    Good product design makes the product intuitive to use: clear onboarding, a smooth user journey, and less effort. The result: increased activation, higher retention, and reduced churn.

  2. Reduce Friction and Support

    When UX is well-designed, users make fewer mistakes, get stuck less often, and ask fewer questions. Result: fewer support tickets and a team that can breathe.

  3. Build faster with a component library

    Every new feature is built from existing components, rather than redesigning a screen from scratch. Result: 2x velocity (and fewer back-and-forths).

They trusted us for their product design

We entrusted Gemeos with a full website redesign and migration, and everything went incredibly smoothly. What stood out most to us was the quality of the art direction: a truly premium, cohesive visual direction, with a clear visual identity and highly polished choices throughout, typography, colors, iconography, pacing, hierarchy, and more. You can tell they have great taste, and above all, a real eye for detail on every screen. On top of that, the team is incredibly responsive and very experienced: they know both design and the technical side inside out. I’d recommend them without hesitation.

What our clients say about Gemeos

4.9/5· 97 reviews

"Most agencies make a great first impression and sell you the dream in those early conversations, but that illusion fades fast once the contract is signed. With Gemeos, it’s different. Gemeos are professional and genuinely committed to doing things right and fast. I really recommend them. And this is the first time I’ve ever recommended an agency.

Quentin MayetVP Marketing @Paradox

“We worked with Gemeos in the summer of 2024 to redesign Modjo’s marketing site and better reflect the brand’s new positioning. The collaboration was incredibly efficient, the agency was highly responsive and adapted to every unexpected challenge. With limited resources on our side, right in the middle of summer, we launched the new site in just six weeks. Site visit engagement increased by 58%!”

Thomas BeylotVP Product @Modjo

“Gemeos are the perfect experts to take over your website from A to Z. Beyond being highly skilled, they were proactive and came up with great ideas throughout the project, a real plus! Thanks for this fantastic Openeat website redesign ;)”

What the FAQ?

What are the key elements of good product design?

Good product design simultaneously meets three requirements: it is useful (it solves a real problem), usable (the user understands how to use it effortlessly), and desirable (it makes users want to return to it). Most products fail on the second criterion: technically functional, but too complex to use.

Key elementWhat it means in practice
Information architectureUsers find what they're looking for without thinking
Visual hierarchyPriority actions are immediately visible
Component consistencySimilar elements behave the same everywhere in the product
User feedbackEvery action triggers a clear visual response
Perceived performanceThe product feels fast, even when loading takes time
AccessibilityReadable, navigable and usable in any context

At Gemeos, we apply these principles to product interfaces as well as websites. The line between product design and web design blurs as soon as a site incorporates dynamic features: simulators, client areas, dashboards.

How to choose a product design agency?

The decisive criterion: does the agency start with users or aesthetics? A serious product design agency begins by understanding user journeys, existing pain points, and business objectives before touching a single screen. If they propose mockups without conducting user research, that's a red flag.

Also, check their ability to work in short cycles with your product team and deliver reusable components within a structured design system.

CriterionGood agencyRed flag
Starting pointUser research, audit of the existing productMockups sent without an in-depth brief
MethodIterative cycles, testing, validationSingle delivery with no back-and-forth
DeliverablesDesign system, reusable componentsUnstructured Figma files
CollaborationWorks hand in hand with your product teamWorks in a silo, delivers at the end of the project

How much do product design services cost?

The cost of product design services varies depending on the product's complexity, the number of screens, and the level of user research included. For an MVP or a partial redesign, expect to pay between €5,000 and €20,000. For a complete product with a design system, projects often exceed €30,000.

Project typeIndicative rangeWhat's included
UX audit + recommendations€2,000 to €6,000Analysis of the existing product, friction points, action plan
MVP design€5,000 to €15,000Wireframes, high-fidelity mockups, prototype
Full product redesign€15,000 to €40,000User research, design system, every screen
Ongoing support€2,000 to €6,000/monthIterations, new features, design system consistency

The retainer model is often best suited for post-PMF startups that regularly release new features. Instead of restarting a project with each evolution, the designer is familiar with the product and iterates directly.

What's the difference between UX design and product design?

Product design is an evolution of the UX role. A UX designer focuses on the user experience: user journeys, wireframes, usability tests. A product designer covers all of this and adds a business dimension: they understand growth objectives, technical constraints, and make design decisions that directly impact product metrics (activation, retention, conversion).

UX DesignProduct Design
Main focusUser experience and journeysUser experience + business goals
Metrics trackedCompletion rate, satisfactionActivation, retention, conversion, revenue
ScopeInterfaces and interactionsInterfaces + product strategy + roadmap
CollaborationMostly with developersDevelopers, growth, marketing, leadership

When should product design be integrated into a project?

As early as possible, ideally before writing a single line of code. Design errors are ten times cheaper to fix in Figma than once they've been developed and are in production. In practice, many startups integrate product design too late: after building a functional but difficult-to-use MVP, they call on a designer to "fix" the interface. This is longer and more expensive than starting on the right foot.

StageRole of product designImpact
Ideation / pre-seedWireframes, testable prototypeValidate the concept without costly development
MVP / seedKey journeys design, lightweight design systemReduce design debt from the start
Growth / Series AUX redesign, full design systemImprove retention and activation
Scale / Series B+Ongoing support, new featuresConsistency as the product grows

What deliverables does a product design agency provide?

The deliverables of a product design project cover the entire chain, from research to production. What distinguishes a good agency from an average one: the quality of the design system delivered. A well-structured design system is what allows your team to continue building consistently without depending on the agency for every new feature.
