A product design agency for software that feels simple.
A product design agency taking you from product vision and brand principles through to polished, high-fidelity design systems that make complex products feel simple.
Design that makes the value obvious.
Product design
Flows and interfaces built around what users are actually trying to do.
Design systems
Reusable components and tokens so the product stays consistent as it grows.
Prototyping
Fast, real prototypes to test an idea before committing to the build.
Brand and identity
A visual style that stays the same in the product and in everything around it.
UX research
Enough research to make confident decisions, without slowing the build.
Design to build
Designers and engineers on one team, so the released product matches the plan.
Complex software does not have to feel complex to the people who use it. When your product does hard work that users never see, the interface is the one place where all that effort either becomes clear or gets lost. As a product design agency, we do the research, the product design, and the design systems that turn a large, complex set of features into something people can learn and use.
What a product design agency actually does
The phrase "product design agency" covers more than screens. When you hire us, you get a team that works across every stage of a product: understanding the people who will use it, shaping how it should work, drawing how it should look, and handing engineering something they can build without guesswork.
In practice, that means a few connected pieces of work:
- UX research. We talk to your real users, watch how they work today, and find where they get stuck. This tells us what to build before we spend time building it.
- Product design. We turn goals and constraints into flows, screens, and states. This is the core: how a task moves from start to finish, and what the person sees at each step.
- Design systems. We build a shared library of components, tokens, and rules so your product stays consistent as it grows and as more people work on it.
- Prototyping. We make clickable, testable versions early, so you can try the product and change it before it is expensive to change.
- Brand and visual design. We make sure the product looks like it belongs to your company, and that the look supports the task instead of making it harder.
- Design to build. We hand engineering clean specs, real components, and answers for the unusual cases, so what gets released matches what was designed.
You do not have to buy all of these at once. Some teams come to us for research alone. Others want a full design system. Most want the connected version, where research informs design and design becomes a system your engineers can reuse.
Why good design is worth the cost, and how to measure it
Design is often treated as the part you improve at the end. That is the wrong order, and it costs money. When people cannot find a feature, cannot finish a task, or make errors they then have to undo, you pay for it in support tickets, lost signups, and customers who leave.
The return is measurable. The Nielsen Norman Group tracks the return on investment of usability work, and in their recent survey, redesigning a product for usability produced an average improvement of about 83% in the metrics that matter (conversion, task success, and similar business measures), down from about 135% in their earlier surveys but still large (NN/g). The point is not the exact figure. The point is that these gains are real and you can measure them, because ROI here is simply the before-and-after difference in a KPI you already care about.
So we treat design as an investment with a number attached. Before we start, we agree on which number we are trying to change: a signup rate, a support-ticket count, time to complete a key task. After we release, we look at the same number. That keeps design honest and keeps everyone focused on outcomes instead of opinions.
How much research is enough
Research can take a whole quarter if you let it. It can also be skipped entirely, which is how teams build the wrong thing with great skill. We aim for the middle, and we match the amount of research to the risk of the decision.
For a decision that is cheap to reverse, a few user conversations and a quick test are enough. For a decision that is expensive or hard to undo, such as a core workflow or a pricing screen, we do more: structured interviews, a look at how people work today, and a prototype we test with real users before any code is written. The goal is not a long report. The goal is a clear answer to "what should we build, and why", backed by evidence you can trust.
We also keep research running in small amounts after launch, not only before it. A short test on a live feature often finds a problem that no amount of early planning would have caught.
How design and engineering work as one team
Design that is passed to engineering with no discussion loses quality at the handover. The handover is where detail gets lost, unusual cases get decided in a hurry, and the released product becomes different from the design.
We avoid this by working as one team. Designers and engineers attend the same planning meetings, review work together, and agree on the components before they are built. Because Reveneau builds the software too, our designers know what is cheap to build and what is not, and they make trade-offs early instead of drawing something that cannot be released on time.
We also release in small pieces. The research behind the DORA program (the Accelerate State of DevOps reports) shows that the strongest engineering teams deliver in small, frequent increments rather than large, rare releases (DORA). We apply the same idea to design: prototype a small part, test it, release it, learn, and repeat. Small steps mean you see value sooner and you catch mistakes while they are still small. If you want the combined design-and-build model, that is exactly what our full product build service is, and it is closely related to our custom software development work.
Working from a brand you already have
Most teams that come to us are not starting from nothing. You already have a logo, a color, a tone, maybe a rough style that grew over the years. You do not want a redesign that removes it and confuses your existing users.
We work with what you have. We start by listing the real parts of your current product and brand: the colors you actually use, the type, the spacing, the components that repeat. From that we build a design system that keeps your identity but removes the inconsistency. Where the brand is incomplete or was never written down, we add what is missing and document it, so the next designer or engineer does not have to guess.
This approach also protects your investment in the product you have. We are not asking you to rebuild everything. We are making the parts you keep work together, and giving you a system so they stay that way. If your product is early and the brand is still forming, our work with startups is set up for that stage, where design and brand grow at the same time as the product.
What you get at the end
The deliverables depend on the scope, but a full engagement usually leaves you with a clear set of things you own and can keep using:
- A record of what your users need and where the current product fails them, so decisions are grounded in evidence.
- Product design for the flows and screens in scope, including the empty, loading, and error states that are easy to forget and costly to skip.
- A design system: a component library, design tokens, and written rules that your team can extend without our help.
- Tested prototypes that show the design working before it is built.
- Build-ready specs and assets so engineering can release what was designed, with fewer surprises.
- A short set of metrics agreed at the start, measured again after launch, so you can see what the work changed.
If you need designers embedded inside your own team for a period of time rather than a defined project, our staff augmentation service places product designers alongside your people, working to your process.
The result we aim for is simple to state and hard to pretend: complex software that feels straightforward to use, backed by a system your team can grow, and numbers that show it worked.

Common questions
Do you do research too?
Yes, Reveneau scales user research to the size of the decision. A cheap-to-reverse choice gets a few user conversations and a quick test. A core workflow or pricing screen gets structured interviews, observation of how people work today, and a tested prototype before any code is written. Research also continues in small amounts after launch, since a short test on a live feature often finds problems early planning missed.
Can you work from our existing brand?
Yes, Reveneau can extend an existing brand into the product or help develop it where the brand is incomplete. The work starts by listing the real parts of the current product and brand: the colors actually used, the type, the spacing, the components that repeat. From that, Reveneau builds a design system that keeps the identity but removes inconsistency, documenting any gaps so future designers and engineers do not have to guess.
Do you hand the design over to our engineers?
Yes, Reveneau hands engineering a clean design system and build-ready specs, or builds the product with its own engineers instead. Designers and engineers attend the same planning meetings and review work together, agreeing on components before they are built, so nothing gets lost at the handover. Because Reveneau also builds software, designers know what is cheap to build and make trade-offs early rather than drawing something that cannot be released on time.
Do we get a reusable design system?
Yes, a full engagement leaves you with a component library, design tokens, and written rules your team can extend without further help from Reveneau. The design system comes from research and product design work, so it reflects how your product actually gets used rather than a generic template. It is built to stay consistent as your product grows and as more people work on it over time.
How do you measure whether the design worked?
Reveneau agrees on a specific number before starting work, such as a signup rate, a support-ticket count, or the time it takes to complete a key task, then measures the same number after launch. This keeps design honest and outcome-focused rather than a matter of opinion. Nielsen Norman Group's research on usability ROI found redesigns produce large, measurable gains in metrics like conversion and task success, which is the kind of before-and-after change Reveneau tracks on every engagement.
What is the process from research to a finished design?
The work moves through UX research, product design, design systems, prototyping, brand and visual design, and design to build, though not every engagement needs all six. Research uncovers where users get stuck, product design turns that into flows and screens, and a design system keeps components consistent as the product grows. Prototypes get tested before anything is expensive to change, and the final handoff gives engineering clean specs and real components to build from.
Can you place designers inside our own team?
Yes, Reveneau's staff augmentation service places product designers directly inside your team for a period of work rather than running a separate, defined project. This suits teams that want senior design capacity working inside their own process and routines instead of a handoff between two organizations. It runs alongside Reveneau's project-based design work, so you can start with embedded designers and move to a fuller engagement later if the scope grows.
Do you design for early-stage products or only mature ones?
Reveneau designs for products at every stage, including early ones where the brand itself is still forming. For startups, design and brand grow together rather than the design system being finished first and the brand being completed later. For more established products, the emphasis shifts toward extending an existing brand and building a design system out of inconsistent, undocumented patterns that accumulated over time as the team and product scaled.
