About · Arxcess+ · Software studio · Kampala · est. 2024

A small studio
building durable
software, on purpose.

Arxcess designs, builds and operates custom platforms for ambitious teams. We take on a small number of projects each year — usually long, sometimes ugly, always shipped. Founded in Kampala. Currently shipping for teams across three continents.

A note from the studio

We started Arxcess because the software meant to run our lives kept getting in the way.

So we picked a small set of problems, a small team to solve them, and a long timeline. The work is slower this way. It is also, finally, the right shape.

How we think
about the work.

The team pact — the behaviours and mindsets we actively encourage. They guide better decisions, better results, and a workplace people stay at for years rather than months.

01
On purpose

User obsessed — not user-mentioned.

We never lose sight of who we are serving and why. Every decision threads back to whether it makes the customer’s life better — not the demo, the press release, or the roadmap deck. The product is the apology when we get it wrong, and the reward when we get it right.

They watched our cashiers for two days before sketching a single screen. That decision saved us a year.

Boring on purpose

Keep it simple. The exciting bit comes later.

We’re not corporate, and we like it that way. The boring, dependable tool wins more often than the flashy one. Complexity has to earn its place — and most of the time it doesn’t. The best code we ship is the code we deleted yesterday.

We did however move the espresso machine. Twice.

03
Chase “better”

An unending desire to improve.

Every project is an opportunity to push past last time — and to walk away from patterns that aren’t working any more. We retro every two weeks, in writing, in public. The same mistake should never appear on the board twice.

Trust, then deliver

Trust is a hundred small deliveries on time.

We cultivate unity as the core of achievement. Trust is the thing built from a hundred small deliveries on time, not from one big promise. We send the demo link on Friday, even when the feature is still ugly — because the conversation matters more than the polish.

Friday demo link, weekly

Even when it’s broken. Especially when it’s broken.

The people
behind the work.

Engineers, designers and operators. Most of us have been shipping production software for a decade or more. We hire slowly and keep the bar high — small team, deep bench.

Aiden Tumwesigye

Backend engineer who has spent the last decade building core banking, ERP and integration platforms for institutions across East Africa. Lives in the gnarly parts — transaction integrity, audit trails, branch-policy approval flows, and the migrations nobody wants to run at 3am — so the rest of the team can move fast.

The best line of code I have written this year is the one I deleted on Tuesday.
