Sites that load anywhere
Server-rendered, budgeted in kilobytes, readable before the fonts land. We test on a throttled 3G profile and a four-year-old Android before we call anything done.

Software
that holds
We build websites and apps for ordinary problems — fares, savings groups, stock books, clinic queues. Things people use on a Tuesday morning, on a cheap phone, with two bars of signal.
What we build
Three things, cast heavy
Most software for everyday users is built as if everyone has a flagship phone and fibre at home. We start from the opposite assumption and it changes every decision underneath.
Mobile
Apps that work offline
Local-first storage, queued writes, conflict rules decided up front. The app keeps working in a basement or a bus, then reconciles the moment signal returns.
- React Native
- Flutter
- SQLite sync
- Push
Rails
Plumbing that connects
Payments, SMS and USSD, maps, identity, receipts. The unglamorous integrations that decide whether a product is usable by someone without a smartphone at all.

- SMS / USSD
- Auth

The stack
Five layers. Each one holds the one above it.
The name is not decoration. Pick any layer to lift it out of the assembly and see what it carries.
Selected work
Built for a Tuesday morning
None of these are dashboards for analysts. They are tools for a shopkeeper, a treasurer, a commuter, a clinic receptionist.
Chama
Savings groups
A ledger for rotating savings groups. Contributions reconcile against mobile-money statements automatically, and every member gets an SMS receipt — including the ones without smartphones.

Njia
Transit
Routes and honest fares for informal transit, crowd-sourced by the people who ride it daily. Maps and fare tables are cached on install, so the app is useful with the radio switched off.

Duka
Retail
A stock book for a one-room shop. Scan or type, sell, restock. It never blocks on the network — the day's takings are on the device and sync when there is signal to spare.

Foleni
Health
A clinic queue that runs over plain SMS. Patients hold their place from home instead of on a bench at 6 a.m., and reception sees the same list on a browser tab.

How we work
Sound it, then set it
Four stages, in order. Each one has to hold before the next is worth starting — which is the whole reason we named the studio this.
-
01 · 0 m
Sounding
Two weeks with the people who will use it, where they will use it. We measure the real problem — the queue, the notebook, the WhatsApp group doing the job today — before proposing anything.
-
02 · 120 m
Setting
We pick the smallest thing that holds: scope, architecture, the one metric that says it worked. You get a fixed price and a plan you can hand to someone else.
-
03 · 520 m
Building
Two-week cycles, each ending in something installed on a real device in real hands. No demo environments that only work on our laptops.
-
04 · 900 m
Holding
Launch is the middle, not the end. We monitor, patch, and keep shipping — or we hand over documented code and train your team to take the watch.
Two-week cyclesSomething shippable at the end of each one.
Fixed-price discoveryYou know the cost of finding out before you commit.
You own the codeYour repositories, your accounts, from day one.
We keep the watchMaintenance on what we ship, for as long as you want it.
