UX and product design

A UX design agency with engineers on the same team

UX design studies how people use a product, finds the steps that get in their way and designs a clearer path. Product design ties those decisions to what the software has to do and what it can do technically. We design apps, AI tools, websites and VR experiences, test the flows before committing to detailed screens, then hand engineering a design it can build, whether that is your team or ours.

  • Research

    Stakeholder and user workshops, in person or over Zoom.

  • Design work

    Wireframes, clickable prototypes, UI/UX design and design systems in Figma.

  • Connected teams

    Our product designers work alongside the engineers who build our web and mobile applications.

What design produces

UX design services we offer

Our product design services cover a full product track or a defined piece of work inside an existing team. Most projects need only some of these.

  • Research and workshops

    Talk with stakeholders and people who use the product. Document what they are trying to accomplish, how they work today and where the process becomes difficult.

  • Product discovery

    Define audiences, important use cases and feature boundaries. Identify the assumptions that should be tested before the team commits to a full specification.

    MVP and prototype development

  • UX audit services

    Walk through the most important tasks in an existing product. Find misleading cues, awkward steps and inconsistent patterns, then prioritize changes against their impact on the user.

  • User flows and wireframes

    Make navigation, order of steps, information hierarchy and expected behavior explicit before visual direction locks in. Engineering can then identify technical dependencies earlier.

  • Clickable prototypes

    Put a proposed interaction in people’s hands so the team can watch where they hesitate, take the wrong path or misunderstand the next step.

  • UI/UX design services

    Design finished screens, interface states, navigation patterns and interactions for web, mobile and immersive products, with visual identity work when the project requires it.

    Mobile app development

  • Design systems and handoff

    Document reusable components, states, behaviors, visual rules and developer notes in Figma. The handoff should explain decisions that aren’t obvious from a static screen.

FantasyBoss: a product redesign, design system and React Native rebuild

FantasyBoss had an older Flutter app and a large set of design files that no longer matched how the product was meant to work. From November 2023 to May 2025 we were its design and development team: we mapped the flows first, brought the screens into one system, then rebuilt the app in React Native.

  • Flows before screens. Registration, joining a league, draft settings and the season mapped as journeys, then compared with the older app.
  • One design system. Adobe XD designs moved into Figma under one typography and visual system, with new screens for teams, standings, trades and invitations.
  • A live draft room. Whose pick is next, the clock, the roster and available players on one phone screen, in sync for every player.

From discovery to handoff

How a UX design project runs

Stages can overlap, and a focused audit or design-system engagement may need only part of the sequence. Review points and revision rounds are established in the scope.

  1. 01

    Discover

    Usually about one week. Understand the people using the product, the work they need to complete and the technical constraints already known.

  2. 02

    Wireframe

    Usually one to three weeks. Work through navigation, screens, decision points and edge cases before detailed visual design.

  3. 03

    Prototype and test

    Usually one to three weeks. Test specific flows through interactive prototypes, with users onsite or over Zoom as the project allows.

  4. 04

    Interface design and handoff

    Usually one to three weeks. Define components, interactions, states and implementation notes, then review questions with the development team.

Role-based product design

Designing one platform for administrators, teachers and learners

For an education platform, administrators, teachers and learners use one underlying content library. Administrators configure and manage content; teachers choose and assign activities; learners interact with the material. We designed those roles as distinct experiences, with authoring and editing tools that let the client’s team produce new material itself.

A machine-learning recommendation feature raised a different product question: how much should the system decide, and how much should remain with the educator? The controls and information shown in the interface establish that relationship.

  • AI product interfaces. For CodeRaven and Insyght, we designed how people read model-generated output, inspect useful context and take the final action.
  • Authoring tools. Activity builders and editing tools, so the client’s team can publish new material without waiting on developers.
Interfaces beyond ordinary screens

UX design for AI products, VR and internal tools

  • AI features and assistants

    A generated answer needs context: what information the model used, what is uncertain and where a person approves the outcome. For Sixty’s AI assistant we built the onboarding and controls people use to give it context and review what it produces.

    AI consulting and development

  • VR and AR interfaces

    Inside a headset, distance, hand tracking, comfort and physical movement change the design. Byldr went through repeated rounds of user testing, and Gigaphoton’s VR training was revised as we identified motion sickness and physical strain.

    UX for mixed reality

  • Design systems

    A shared library of components and interaction rules keeps new screens coherent as a product expands. We document states and constraints for the people implementing them.

  • Internal and authoring tools

    Software used to create or administer other content needs especially clear permissions, publishing steps and ways to correct mistakes. We design those workflows as part of the product.

Where to begin

Where a UX design project usually starts

Most engagements begin in one of these places. Scope and price are agreed in writing before work begins.

  • An idea without a specification

    Discovery, prioritized use cases, user flows and a prototype can define what the first version should do.

    MVP and prototype development

  • A product people struggle to use

    A UX audit finds the specific screens or tasks worth fixing before you commission a larger redesign.

  • A team whose interfaces are drifting

    A design system gives designers and developers shared components, visual rules and interaction behavior.

Design handoff to your developers, or design and build with ours

You can stop at a documented handoff or carry the design into development with our engineers.

Handoff. Figma files, documented components and states, interaction notes and the reasoning behind decisions, in a form another team can build from. We stay available as implementation raises new questions.

If you already have a product team, we can take a defined part of the work, such as research, one flow or the design system, and leave the rest with you.

Design and build. The same team carries decisions from research into production, so the people who designed a flow are there when engineering questions come up.

FAQs

Questions about UX and product design.

What do UX design services cost?

Cost depends on the research, number of user paths, prototypes, testing and interface deliverables involved. We agree on the exact scope and put the estimate in writing before starting.

How long does product design take?

Discovery usually takes about a week. Wireframing, prototyping and UI design generally take one to three weeks each, and some stages can overlap.

Can a product design agency work with our developers?

Yes. We can deliver research, an audit, selected flows or a design system for your current engineers to implement, with annotated files and development notes.

Can SLIDEFACTORY design and build the product?

Yes. Strategy, design and engineering can continue together through production, or we can stop at a documented design handoff.

Do you test with real users?

Yes, where the scope calls for it. User sessions can take place in person or over Zoom, using interactive prototypes or the existing product.

What is included in UX audit services?

We review core tasks, confusing navigation, missing states and inconsistent patterns, then deliver prioritized issues and recommended changes.

Can you improve a product without redesigning every screen?

Yes. An audit often identifies contained improvements. A full redesign is one possible result, depending on what is creating friction.

Do you design AI and internal tools?

Yes. CodeRaven, Insyght and education-platform authoring tools are examples of interfaces where users need clear controls over complex systems.

Do you design for accessibility?

Yes. We design and build to WCAG when you request it, at the level you specify, and agree the criteria and how they will be tested at the start.

Do you design for VR and AR headsets?

Yes, including hand-tracked building tools for Byldr and VR maintenance training for Gigaphoton. We test immersive interfaces in the headset, not only on a flat screen. Our post on the fundamentals of UX design for XR and spatial computing covers the principles.

Is UX and product design the same as web design?

No. Web design produces a website. Product design produces software people use to get something done: an application, a learning tool or an internal system. If you need a website, see web design and development.
