About IO

"It is a myth that individuals start companies. Teams start companies… especially innovation driven enterprises."
- Bill Aulet

At IO we conceptualise, build and commercialise tech innovations that we believe will bring the power of the internet to the world in new and useful ways. Our ultimate vision is to harness our relentless curiosity and yearning for learning to become bold discoverers and problem-solvers for society.

Software Development and Engineering

15 years of software development experience can turn your ideas into reality. We work with large multinationals and small startups to build scalable, amazing software. We don’t shy away from difficult problems. Speak to us if you’re deploying satellite solutions to rural Nigeria or building the next mobile retail experience in New York.


Ultimately, everything we build interfaces with people. From concept all the way through to quality assurance, we take note of why and how people use things and try to improve the journey. Most users are unaware of what a good user experience is, but everyone knows what it is not. We aim to allow your users to engage with you, blissfully ignorant.


Proper deployment and integration are what separates us from the animals. Our infrastructure is defined in code, saved in git repositories, perfectly reproducible, atomic and always scalable. Smaller projects get to run on our shared infrastructure and larger ones have custom setups. We are cloud agnostic but do prefer the Google cloud.

Passmarked was born out of our quest for perfection and love of quality. There was no way to determine whether anyone’s work stood up to standards and best practices so we created it. Passmarked scores how well your site works and a better score means a better performing site driving more sales and user engagement.

Design is an integral part of the process of conceptualisation, development and execution of ideas at IO. It is not a separate process or an afterthought. IO is home to a team of talented and dedicated designers who constantly try to raise the bar on interactive digital design, product design, user experience, branding and brand development, and other areas of design that bridge the gap between tech and humans.

NProbe Collector

Nprobe Collector was written in Go. It analyses and aggregates TCP traffic according to its source and destination IP addresses using the NetFlow protocol. The objective is to see how bandwidth was used and then potentially treat certain locations differently in terms of pricing.

As great believers in the collective power and value of the Internet, we are hedging our bets that Blockchain is the one of the world's greatest new technological revolutions - one that is here to stay. And we're not just watching from the sidelines, we are joining the revolution. We’ve built production systems on top of Ethereum, the fastest growing blockchain, and understand how the blockchain and crypto-currencies can enable previously impossible businesses.

Discovery has become too easy. 50 years ago, before the Internet and GPS, people explored the world around them, often walking somewhere just to see what was there. Rover is an experimental app that tries to reignite a sense of exploration and problem solving.

Can you find one of our fascinating locations when the only piece of information you’re given is how far away you are? Once you’re close enough we’ll tell you why you’re there.

There are three fundamental challenges in making the Internet accessible to everyone: Internet capable hardware (eg. a mobile phone), network coverage and the cost of data.

We’re working with partners to provide cost-effective internet access and free life-changing content to the underdeveloped communities who need it the most.
