We build the systems a business runs on.

We learn how your business works, then build the software around it, from the screens your staff use all day to the reports you make decisions with. What we hand over is finished and ready for your team to use.

Based in Georgetown, Guyana. We reply within one business day, wherever you are.

What a business stands on

Look at a company from the street and you see its offices, floor above floor, and its delivery truck on the road. What it stands on is out of sight. Beneath every business lies a layer of records, of what was sold and what is owed, of what was promised and by when, and every decision made above it rests on that layer being true.

Most of the time nobody checks. A figure is copied from one spreadsheet to the next, a total is rounded, a date is remembered rather than read, and the business carries on, standing on ground nobody has tested.

We build that layer, and we build it to be checked. A result in mathematics is accepted only when its proof is written out so that someone else can check every step. We hold the systems we build to the same standard, so that whenever anyone asks where a figure came from, you can show them.

Habits we keep on every build

Each one keeps that layer true in a different way.

We agree the rules before we build anything.

Every figure can be traced to its source.

When something goes wrong, the right person hears about it.

Nothing is paid or reported until the totals agree.

What we build

Sound records are only the start. On top of them, software can now do much more than it could a few years ago. A phone line can answer calls at any hour, in English or Spanish, and hand the difficult ones to a person. A camera at the warehouse door can count every pallet that leaves, and years of sales figures can help you decide what each branch should order next month. We take on work as small as a tool for one person and as large as a system a whole company relies on.

Orders, stock, customers and money are kept together, so everyone sees the same numbers at the same time, on the phones and computers they already have. People see only what their job needs, and every change records who made it. The work carries on even when the internet goes down.

A deliveries board and a driver's phone. The phone loses its signal, the delivery is saved anyway, and the board catches up when the signal comes back.

A single project often needs more than one of these, so we build each to work with the others and with the systems you already use.

Research in mathematics and finance

We hold our own research to the same standard. On 12 October 2026 the OEIS, the reference mathematicians use for integer sequences, published five new terms that our programs established for one of Paul Erdős's problems. Two programs, written in different ways, searched every number up to 20 trillion, and their answers matched. We have also fitted the US Treasury's yield curve for every trading day since 1990, and we can use a curve like this to show what your own loans would cost if interest rates rose or fell.

How we work

Every project goes through the same five steps, whatever its size.

  1. 01

    Understanding

    We talk to the people who do the work and see how it is done today, including the shortcuts they have found.

  2. 02

    Plan

    We set out what we will build, and how we will both know it is working.

  3. 03

    Build

    You see it working early and at each stage, so decisions are made with the real thing in front of you.

  4. 04

    Handover

    The finished system goes live in your business, and your team is shown how to run it.

  5. 05

    Aftercare

    Fixing anything that does not match the plan is part of the job. When you want more, we already know how your system works.

What every build comes with

  • A fixed price, agreed in writing before any work begins
  • Larger builds delivered in stages, each paid for on delivery
  • Source code, files and accounts in your name from the first day
  • Your records on a server, backed up every day, and yours to download at any time
  • Testing with your own data before handover, and again after every change
  • A written guide your team can follow without us

Stratum ICS

Stratum is the word geologists use for one of the layers of rock that the ground is made of. ICS stands for Integrated Core Systems. Together, the name describes what we build: the systems a business stands on, often without noticing them.

We work by call and message. Guyana shares New York's time for most of the year, so anywhere from Toronto to Houston, our working day is never more than two hours from yours.

In Georgetown it is
