Start Product Design with what your team already knows

Work on a new product can begin once the problem and audience are understood, even if the experience still needs direction. One defined feature keeps the scope focused without reopening the entire product. For an existing workflow or product area, the scope can target what needs to change while preserving what already works. If the problem, audience, or priorities remain unresolved, begin with Product UX Discovery; if several journeys or the visual language need reconsideration, choose Product Redesign.

1

Discovery

We review the available evidence, business goals, intended users, and known constraints. We add research or engineering input only when the agreed scope requires it.

2

Concept

We shape the product logic, core journeys, and key interactions, then review the proposed flows with you before moving into detailed visual work.

3

Design

We agree on the visual direction and key screens first, then develop the remaining screens, states, and platform coverage defined in the scope.

4

Iteration

We collect consolidated feedback in Figma or another agreed channel, apply changes through the defined review rounds, and finish with the approved design.

Design handoff for your developers

Your team receives the approved design in editable Figma, including final screens, agreed flows, and necessary states within scope. Developers can see how screens connect and how the interface should behave along those flows. We keep final designs separate from drafts so they know which version to implement. Use our design handoff checklist to identify details to clarify with your developers before implementation.

We hand over the components, styles, and assets created for your project alongside the final screens. Together, they show your developers where components and assets appear and which visual rules apply across the approved design.

We share the design context with your development team, usually through a handoff call. Developers can walk through the approved flows with us and ask about the intended behavior before implementation. If your team needs formal engineering review or design QA during the build, we scope that work separately.

Why choose Merge for your product design?

Design around your priorities

Design around your priorities

Our designers use your business context and product priorities to choose a design direction and focus the work on the problems you need to solve.

UX clarity and visual craft

UX clarity and visual craft

We connect information structure with visual hierarchy, using layout and consistent styling to help users find, scan, and understand important information across each screen.

Direct designer access

Direct designer access

You speak directly with your designers through agreed calls or async updates, so you know what's in progress and can share context while choices are still open.

Product logic and technical fit

Product logic and technical fit

We consider the tasks each user role needs to complete alongside implementation constraints. Engineers can join the discussion to explore simpler options.

Control over scope changes

Control over scope changes

Changes that affect the budget or timeline require your written approval. We explain the impact first, so you can decide whether the additional work is worth the extra cost or time.

Clear interface feedback

Clear interface feedback

Within the agreed flows, we design responses to user actions and the necessary interface states to help people understand what happened and what they can do next.

Our product design experience

Explore our product design projects, including trading interfaces and virtual workspaces, to see what each product needed and the design work we contributed.

Versus Trade

Versus Trade lets users trade asset-versus-asset CFDs and track performance on web and mobile. The project set up Client and Partner products with quick flows, data-heavy views, MT5 redirects, and RTL support. We led product design, with journeys, states, IA, and priorities, tuned for Asia and MENA. The launch hit plan, scaled across 3,000 screens, and stayed coherent.

HeyLady!

HeyLady helps women practice spoken English in a women-only community. The project needed a single source of truth for a fast-moving product. We built a design system with tokens, components, patterns, etc. It reduced rework, aligned teams, and sped delivery across chat, Events, and onboarding.

Mural

Mural is a visual collaboration platform giving teams an AI-powered space to work. One of their previous projects reimagined its 2D boards as an immersive VR workspace for teamwork. Alongside their team, we led product design and worked with spatial UX flows, VR interface patterns, Unity-ready specs, and storyboard methods.

Agentless

Agentless is a SaaS platform that helps U.S. buyers complete home purchases without agents. The project focused on designing an AI-assisted workflow that clarifies property research, offer preparation, inspections, and state-specific agreements. We led product design that included UX discovery, wireframes, prototypes, and a UI library for accessible, error-proof forms. Outcome: a clear end-to-end flow that increases buyer confidence.

Block Earner

Our challenge was crafting a product design that seamlessly balanced intuitive user experience with robust security measures. The website and mobile app interfaces were redesigned over 300 hours, focusing on user accessibility and brand elegance.

Invisibly

Our web designs had to be spot-on for both B2B and B2C, a challenging but crucial task. For the business side, we focused on visualizing data simply and clearly. Lastly, our quality designs ensured a smooth experience on any device, from phones to computers.

Siren’s instilling confidence

The product design aimed to instill confidence. Every element, from the illustrations to the animations, was tailored by our design team. A centerpiece of our visual strategy was the Siren mascot, a cheerful robot, serving as a beacon in the complex landscape of cybercrime.

Product design FAQs

If the product's user flows and interface still need to be defined, discuss a broader design engagement. If you already know the flow or interface that needs work, scope that task. Product design and UI/UX overlap, so define the scope instead of choosing by label alone. Merge's digital product design services can cover end-to-end design through approved designs and developer handoff. Development is separate, whether your engineers or Merge build it.

Research, usability testing, and a full design system can be included when they are part of the agreed scope. For research or testing, identify what you need to learn and which assumptions need checking. For a design system, define the components, usage guidance, and documentation your team expects. The baseline is the approved design in editable Figma, with the components and styles created for the agreed work. Those project components alone are not a full design system.

Share your current product or design files, any research or user feedback, and the business goal behind the work. Include known technical constraints and brand guidelines if you have them. Identify any product or file access needed for the agreed work and the contact who can arrange it. A startup without a live product can begin by describing its intended users and the problem it wants to solve. These materials help us define the starting point, including what can inform the design and which questions still need work.

We estimate the timeline from the flows, screens, and states required, the platforms or screen sizes covered, and any research or testing in scope. Onboarding, access, review rounds, and the time your team needs for feedback and approvals also affect the schedule. For one standalone UI/UX engagement on an existing platform, we planned four weeks for the initial scope. After the first milestone, we agreed with the client to extend the work; the engagement lasted about eleven weeks in total.

Your team reviews logic and flows first, then the visual direction and key screens, and finally the full agreed design. We recommend one client decision-maker who gathers stakeholder input and confirms approvals in writing. Leave feedback in Figma or the agreed project channel. Review rounds and feedback windows should be agreed in the statement of work, with time for stakeholders to review before that person returns a consolidated response.

We distinguish feedback on the agreed design from requests that add or change the work. Refining a screen within an agreed review round is different from adding a user flow, platform, or breakpoint. A change to an approved direction may also need a scope discussion. We assess the impact with you, and any change to the budget or timeline needs your separate written approval before that work proceeds.

Yes. Your team can handle implementation, and your engineers can join design discussions to raise constraints or consider simpler options. We take technical feasibility into account during design. A formal review of architecture, APIs, or implementation estimates is separate work that we can scope with you if your project needs it. Design QA during the build can also be scoped, so we can compare the implementation with the approved design and discuss discrepancies with your team.
