Design that looks
refined and
works perfectly.

We design digital products people actually enjoy using - not just ones that pass a visual review. User research, interaction design, design systems, and pixel-precise implementation: from the first wireframe to the final component in code.

Every discipline from research
to shipped component.

Good design isn't a layer added at the end of engineering. We embed design into the product process from day one - which is the only way to get products that feel considered rather than assembled.

User Research & Discovery

Most design problems are actually research problems - the team built the wrong thing because they assumed rather than asked. We run structured discovery programmes that replace assumptions with evidence before wireframe one is drawn.

Qualitative interviews with 6–12 target users per research sprint
Jobs-to-be-done mapping and user journey documentation
Competitive UX audits and heuristic evaluation of existing products
Insight synthesis into actionable design principles your team can reference
Ongoing usability testing at every major product milestone

Product Design & Interaction Design

The gap between a nice Figma file and a product people actually use is where most design agencies fall down. We design interactions with the implementation constraints in mind - component states, loading behaviour, error handling - not just the happy path.

High-fidelity Figma designs with complete component and state coverage
Interaction prototypes for user testing and engineering handover
Detailed design specifications with measurements, tokens, and behaviour notes

Design Systems

A design system is the difference between a product that scales and one that fractures into inconsistency as the team grows. We build systems your engineers can actually implement - tokens, components, documentation - not just a Figma library with aspirational names.

UX Audit & Redesign

If your product exists and has problems - drop-off rates, support tickets about confusion, tasks people can't complete - a UX audit is faster than rebuilding from scratch. We identify exactly where and why the experience breaks.

Mobile App Design

iOS and Android design that follows each platform's conventions while maintaining a coherent product identity. We design for the real constraints: thumb zones, system fonts, dark mode, accessibility standards, and the specific patterns users expect on each platform.

Five phases. One continuous
loop of user feedback.

We treat design as a cycle rather than a handoff. Each phase produces artefacts that feed the next one - and real user input enters at phases one, three, and five.

Step 01
Discover

User interviews, competitive analysis, and problem framing. We challenge the brief before we accept it.

Step 02
Define

Personas, user journeys, and design principles that the rest of the process is accountable to.

Step 03
Design

Wireframes → high-fidelity Figma → interactive prototype, tested with real users before engineering starts.

Step 04
Build

Design system components implemented in Storybook, engineering reviews, and QA against the specification.

Step 05
Measure

Post-launch usability testing, analytics review, and iteration. Design doesn't stop at release.

Design and engineering in the
same room from the start.

We close the gap between Figma and production.

Most design work falls apart in the gap between the design file and the implementation. We've been on both sides of that handover - and we design in a way that respects what engineers actually need to build from.

"Sequere's design team was the first we'd worked with who understood what 'production-ready' actually means. The handover from Figma to our engineers was seamless - no missing states, no ambiguous spacing, no late surprises."
Research before pixels

We don't open Figma until we understand who uses the product and what they're trying to accomplish. Opinions about colour schemes are easy. Validated understanding of user behaviour takes work.

Figma files engineers can build from

Proper component naming, complete variant coverage, interaction notes, responsive behaviour specs, and handover documentation. Not "here's the design, figure it out."

Consistency through systems

Design systems are an investment that compounds. We build them to be maintained, extended, and owned by your team - not locked in our processes and tooling.

Accessibility from day one

WCAG 2.1 AA compliance built into the design, not retrofitted. Colour contrast ratios checked in tokens, focus states designed, and screen reader flows considered in the architecture.

Honest iteration, not perfect handoffs

We treat the first design as a hypothesis. Usability testing often changes things. We'd rather show you early prototypes that reveal problems cheaply than perfect mocks that hide them expensively.

On time, on spec

We track design progress against milestones the same way engineering tracks sprints. Scope changes go through a change process, not quiet expansion. You always know where we are.

You own everything

All Figma files, all research data, all documentation - transferred to you with no licence strings. If you want to continue with your in-house team after delivery, the artefacts are structured so they can.

Cross-platform from the start

We design for web, iOS, and Android with an awareness of what's shared and what's platform-specific. One design language, three implementations - not three separate design projects.

The tools we use. The ones we don't. And why.

Opinionated about tooling.

Figma is the industry standard for good reason. We use it for everything from wireframing to handover. Beyond that, we pick tools that solve actual problems rather than tools that look impressive in a pitch deck.

What people ask before they start

The range is genuinely wide. A UX audit of an existing product runs from $8,000–$20,000. A full product design engagement - research through high-fidelity Figma for a SaaS product - typically falls between $35,000 and $90,000 depending on the complexity and number of platforms. A design system build sits somewhere in the middle. We give you a fixed-price estimate after a free scoping call, so there are no billable-hours surprises.
You can skip it - and it's usually more expensive when you do. Research-lite projects tend to produce more iterations, more rework, and more post-launch feature changes as the team discovers (expensively) what users actually want. That said, there's a calibration here: a product used by a narrow, well-understood audience with existing analytics data needs less research than a consumer product entering a new market. We'll tell you honestly what we think is necessary for your specific situation.
UX (user experience) covers the structure of how a product works - information architecture, task flows, interaction design, and whether users can actually accomplish what they came to do. UI (user interface) covers how it looks - visual design, colour, typography, spacing, and the aesthetic layer. In practice, the two are deeply intertwined: a visually beautiful product with a confusing structure is still a bad experience. We do both, as an integrated discipline rather than a sequential process.
Handover is where most design projects fall apart, so we treat it as a designed artefact rather than an afterthought. Figma files are structured with proper component naming, complete variant coverage, auto-layout throughout, and an explicit handover page with spacing specs, typography tokens, and interaction notes. For teams using Storybook, we integrate directly. The measure of a successful handover is whether engineers can build from the file without asking a designer to clarify every other element.
Both, depending on what you bring. If you have a brand identity - logo, colours, typography - we design within it and extend it into a product design language. If you're starting from zero (or if the existing brand guidelines weren't designed with digital products in mind), we'll flag that and scope the brand-to-product translation as part of the engagement. Many early-stage companies have a logo and a colour palette but no design tokens - that gap needs filling before component design begins.
Yes, and it's a different skill from greenfield product design. We start with an audit to understand what's working, what isn't, and what users have built habits around. Redesigns that ignore existing patterns frustrate users who already know the product; redesigns that refuse to change anything don't fix the problems. The right balance is a judgment call based on analytics, research, and honest conversation with your team about what you're trying to achieve.
WCAG 2.1 AA as a baseline - colour contrast ratios in all tokens, visible focus states on all interactive elements, text alternatives for non-text content, and ARIA labelling guidance in handover documentation. For public sector products or regulated industries, we can work to AAA where required. Accessibility is easier to design in from the start than to retrofit - it's part of our component specification process rather than a final review checklist.
Jakob Nielsen's research suggests five users find 85% of usability problems in a product, and it's held up well in practice. We typically run usability sessions in rounds of five, synthesise findings, make design changes, and test again. For quantitative validation (checking whether a specific change improved a metric) you need larger samples - that's typically done post-launch with A/B testing rather than moderated sessions. The honest answer is: more than zero, and five is usually enough to find the problems worth fixing.
