Estates run serious money on WhatsApp and memory.
We're building Residium to change that: one system for estate money, people, and the gate.
The people running estates are doing serious work with systems that were never designed for it.
A WhatsApp group is good for conversation and hopeless as a resident register. A bank alert says money arrived; it doesn't say which levy it settled, or for which flat. And the gate logbook is, honestly, a notebook.
These tools have carried more responsibility than they were built to hold. Residium gives that work a proper home.
An estate should be able to answer, without calling anybody: who belongs here, and what happened to the money.
Four principles we keep coming back to.
They shape what gets built, and what gets refused.
01
Every naira should leave a record.
Collections, allocations, contributions, and spending should be understandable without searching bank alerts or asking one person for a spreadsheet.
02
Policy should be visible before it's enforced.
Residents and staff deserve to know what a rule is, why a status changed, and who's authorised to make a decision.
03
Software should support judgment. Your estate stays in charge.
Residium gives security verified information and records the outcome. Each estate remains responsible for its policies and people.
04
Built for service charge and DISCO meters, not a generic billing tool.
We design for phone-first onboarding, service charge, security levies, Nigerian payment methods, DISCO meters, and what actually happens at an estate gate.

Residium is its first product: one system for estate money, people, and the gate.
A small team today, onboarding its first estates.
The estate that started this.
Once or twice a year, the estate this started in runs a revenue drive. The main gate is locked, everyone is routed through one exit, and residents are asked for their receipt on the way out. It works while it lasts. But defaulters know when it is happening, so they simply stay away until it is over, and then nothing happens again until the next one.
The rest of the year, the gate runs on a phone. Residents who have paid get their number saved in the security handset. Call about a visitor, and if your number is not in there, the gate does not open. But that list only knows who had paid on the day it was written. It cannot tell a guard who is current this month, and nobody goes back to take a name off it.
The instinct was right — tie the gate to who has paid. There was just no way to keep it true. That is why we built Residium. No two estates run the same way, so management decides which of its own fees count at the gate, and the gate checks them on every scan. It should know today's answer, not last February's — and nobody should have to lock a gate once a year to find out.
Estates where the records are current and decisions don't depend on who's holding the phone.
A chairman who can answer who has paid, without calling anybody
A resident who can see what is due and pay it from a phone browser
A guard who knows where a unit stands before he opens the gate
A committee meeting that starts from a record, not an argument
See what this could look like for your estate.
