01 · Fintech · 2026 · Brand, product, design system

Halcyon Bank

Halcyon had a good product buried under a nineteen-screen onboarding flow and an identity borrowed from a challenger bank two funding rounds ahead of them. We started by cutting rather than adding: eleven screens went, the marketing site lost half its pages, and the app opened on a single number instead of a dashboard. The identity followed the interface rather than the other way round.

The hardest part was compliance. Every simplification had to survive a regulatory read, which is why the project ran eleven months rather than seven.

Northgate Foundry

A ninety-year-old sand-casting foundry selling almost entirely to contractors on price, while the architects specifying the work never heard their name. We rebuilt the identity around the thing that was actually rare — the pattern shop and the people in it — and put the making at the front of every touchpoint.

Six months on, direct architect enquiries had gone from a handful a year to two a week. Turnover barely moved in year one; margin did.

Ember & Ash

Nine restaurants opened over twelve years, each with its own logo, menu format and booking widget. We built one system with deliberate room in it: shared typography and grid, per-site colour and photography. The booking flow was rebuilt around the only two questions people actually answer — when, and how many.

Direct bookings more than doubled inside two quarters, which mattered because every one of them avoided a platform commission.

Solstice Health

A referral tool for clinicians who had, by our own stopwatch, about ninety seconds per patient to use it. We shadowed eleven clinics, cut the form from four screens to one, and moved everything optional behind a single disclosure. Nothing was added; a great deal was removed.

Worth noting: the first release was slower than the paper process it replaced. It took two further rounds of testing to beat it.

05 · Publishing · 2024 · Brand, web

Vellum Press

Nine hundred titles, a devoted readership and a website that could only be browsed alphabetically. We modelled the catalogue around how readers actually describe books — mood, length, translator, series — and let the identity stay quiet so the covers could carry it.

The typographic system was drawn to work at 11px in a footnote and at 200px on a poster, which turned out to be the whole project.

Kestrel Mobility

A ticketing platform in 42 markets that had been localised into 42 different products. We consolidated it into a single token architecture and component library across web, iOS and Android, then wrote the contribution and deprecation rules — the part that decides whether a system survives.

Removing three quarters of the CSS was satisfying. Getting six regional teams to agree on a review process took considerably longer.

07 · Retail · 2023 · Ecommerce, web

Atlas Provisions

A pantry brand with excellent products and a checkout losing a third of its carts. Most of the loss was a delivery estimate that only appeared at the final step. We moved it to the product page, rebuilt the basket around substitutions rather than removals, and simplified the range architecture.

No new features. The gain came entirely from moving information earlier.

Fable Interactive

A games studio with eleven trailers that looked like eleven studios. We wrote a motion grammar — how things enter, how type behaves, what the cut rhythm is, what the sound does — and rebuilt the title sequence and store presence around it.

The rules fit on two pages. That was deliberate: a motion guide nobody reads is a motion guide nobody follows.

Lantern Public

A public service used by people in difficult circumstances, frequently on old devices and metered data. We set the design target as a five-year-old Android on 3G and let everything else inherit from that. The result is 84kb on first load and no layout that depends on hover.

This project is the reason accessibility moved to week one for every engagement after it.

Quarry & Co

A developer who wanted to stop sounding like one. We cut the renders, photographed three finished buildings with people in them, and rewrote the copy in the first person. The identity is deliberately plain so the buildings do the work.

Enquiry quality changed more than enquiry volume — which is what they had asked for.

Meridian Textiles

A mill selling to interior designers through a printed catalogue last redesigned in 1998. The archive was the asset: 4,000 sampled weaves nobody outside the building had seen. We built the identity around the archive and made the sample request the primary action on every page.

A physical swatch still converts better than any image, so the site is designed to get people to ask for one.

12 · Science · 2023 · Brand, web

Orrery Labs

Eleven scientific instrument lines, each named and styled by whichever team happened to ship it. We gave the catalogue one visual grammar and a naming convention that encoded what each instrument does, so the range finally read as a company rather than an acquisition history.

The sales team stopped having to explain that they were one business. That was the entire return, and it arrived in month four.
