Software built
to live {{ cycleWord }}.

We have been building high-throughput, high-quality software for the telecoms and related industries since 2010, offered as an outsourced and managed service. Successful software projects live and evolve forever; we build on that premise.

If we can build telephony, we can build anything.

The stack

Two decades at the front of the telephony software revolution.

Large telephony ecosystems are among the most demanding challenges in software: many variables in tiny time frames, multiplied by tens of thousands of concurrent calls writing billions of lines, plus rating, month-end billing and real-time monitoring of those streams.

TELEPHONY INTEGRATIONS & NEW DEVELOPMENTS

Plug your software in or build something new.

Solving software problems in telephony usually means joining two worlds that were never designed to meet. We do that work: screen pops, click-to-dial, dispositions written back, recordings attached to tickets, and reporting your business already understands. Or building something completely new in the telephony space.

BESPOKE SOFTWARE DEVELOPMENT

Anything you can throw at us.

Telephony software is among the hardest work in the industry — thousands of variables inside milliseconds, at tens of thousands of concurrent calls. Building it for two decades prepared us for everything else, so bespoke systems outside telephony are a simpler version of the same engineering.

Clients who trusted us with an unusual idea have ended up with systems nobody else was running — every one of them built for scale from the first line.

Projects we have completed.

Built at scale
CRM 10 000 concurrent users A customer relationship platform carrying ten thousand concurrent users, with live geolocation for precise address mapping built to the client’s own requirement.
Telephony 20 000 concurrent calls Voice applications administrating twenty thousand simultaneous calls — routing, media, rating and monitoring all held inside real time.
E-commerce Millions of users, on Black Friday Retail platforms serving millions through peak trade, wired into warehouse inventory and physical in-store point of sale.

More about how we work.

QUESTIONS WE GET
Do you take over existing codebases?

Often. We audit what is there, stabilise it, then evolve it. Rewrites are a last resort, not an opening position.

Who owns the software?

You do. We build it as an outsourced and managed service; the code and the data are yours.

Where is it hosted?

Anywhere globally, but our Teraco-based data centre was designed to be the best home for real-time applications in South Africa.

Can you build things that are not telephony?

Yes. Telephony is the harsher constraint, so most other industries are a simpler version of the same engineering.

Bring us the epic.

NEXT STEP

Tell us what the software has to do and how long it has to live. We will scope it, cost it honestly and build it to last.

Not sure which of these you need? Meet with us and we will work through the requirement together — we would rather scope it properly than sell you the wrong thing.
