Aven Atelier

2 designers, 6 engineers

10 weeks

Project inquiries up 42%

Retail banking rebuilt around a single balance-first screen.

Most people open a banking app to answer one question: how much is left. We cut the dashboard to that one answer and pushed everything else a tap deeper, then rewrote every error message in the language customers used on the phone.

Identity and website for an architecture and interiors studio. One typeface, one grid, and photography doing the talking, so the site reads the way the buildings do.

Nine out of ten sessions ended inside twenty seconds. Support tickets told us why — customers were hunting for a number that should have been the first thing on screen.

Six months of tickets read before opening Figma, twelve support calls attended, and an HTML prototype on day nine, because a page that scrolls answers questions a static frame never will.

One balance-first screen, everything else a tap deeper, two tabs removed, and every error message rewritten in the words customers used on the phone.

Morrow Roasters

1 designer, 4 engineers

A patient portal that explains the result before it shows the number.

Every lab value got a one-line human translation, written with three clinicians in the room. The number is still there, one scroll down, for the people who want it.

Identity and packaging for a specialty coffee roaster. One condensed wordmark on unbleached paper, and a colour block that changes with the origin, so the shelf reads as one brand and three coffees.

Every result release triggered a wave of phone calls. Patients could read the value but not what it meant for them, so they asked the only person available — the nurse line.

Three weeks sitting with the nurses, writing down the exact sentence they said on the phone. Those sentences became the copy; the clinicians edited them rather than approving them.

Every lab value now carries a one-line translation, a plain range, and one sentence about what happens next. Nothing else on the screen changed.

22%

Point of sale for staff who will never read a manual.

Big targets, no nested menus, one undo that always works. We tested with new hires on their first shift: four minutes to the first sale, down from roughly four hours of training.

E-commerce and art direction for a travel apparel brand. Weatherproof outerwear shot where it actually gets used, and a moulded pulp packaging system that arrives looking like the product it protects.

Training took two weeks and still produced mistakes at the counter. Every mistake became a queue, and every queue pulled a manager off the floor.

We timed real transactions on the shop floor, then rebuilt the system around the three actions that filled most of the day and moved everything else behind one clearly labelled door.

Big targets, no nested menus, one undo that always works, and a component library two engineers can build with without asking a designer.

Soma Lab

Solo

Identity and site for a solar installer that had quoted by phone for a decade.

The site now does the first half of the sales call: what it costs, how long it takes, what happens on the roof. The phone call starts at the second question instead of the first.

Brand identity and store for unisex skincare. Three products share one bottle: what changes is the colour of the formula and a dosing scale printed on the glass, so the label has nothing left to explain.

Every lead arrived by phone and every call started from zero: what it costs, how long it takes, whether the roof is right. The site answered none of the three.

Four installs ridden along with, the crew photographed instead of stock bought, and the pricing page written as the answer to the first ten minutes of every phone call.

An identity that survives a van wrap and a site that has the first half of the sales conversation before anyone picks up the phone.

Ordinal

2 designers, 9 engineers

Ten operations screens replaced with one prioritised queue.

Dispatchers were reading six tabs to decide what to touch next. The queue makes that decision visible: one list, ordered by consequence, with the reason written next to each row.

Digital catalogue and website for a modular furniture studio. One connector holds the whole system together, so the catalogue is numbered by configuration and every build gets a page of its own.

Handling one exception took four minutes and a good memory. New dispatchers needed months before anyone trusted them with the busy shift.

I shadowed the night shift, recorded which fields were actually read, and cut the rest. The prototype ran on a week of real data, so the ranking could be argued with instead of admired.

One priority queue sorted by what breaks first, six tabs collapsed into a single panel, and every action reachable without leaving it.

Nightshift 25

A habit tracker with one rule: never guilt the user.

Missed days are shown as facts, not failures, and the streak is not the hero of the screen. Two years in, day-30 retention has held at 41% without a single push notification about a broken streak.

Campaign and interactive site for an electronic music and visual culture festival. One system of vertical bars: built in light at the entrance, printed on foil across the city, and running as a live timetable on the phone.

Streak counters punish the exact moment a person needs the app most: the day after they miss. Most people delete it that week.

One rule tested with forty people over six weeks — show missed days as facts, never as failures. The version with guilt in it lost every round.

No streaks, no red, no notification that scolds. A missed day is drawn as a gap, and the next day opens exactly as usual.
