Sibella Knott-Craig

Sibella is our co-founder and CEO.

With her qualification as a Chartered Accountant, her ambition to make the world a better place through technology and her prior business experience in financial management and consulting at global and listed companies including Deloitte and Siemens, she now is tackling ‘Healthy Tech’ for kids.

Sibella enjoys working on new projects and developing bespoke apps for clients, but is most passionate about Tribage’s own range of educational apps in local African languages, called Xander.

These award-winning apps have been designed to support early learning in the vernacular, and are inspired by her children. She combines the games they love playing with the homework that needs doing to create enjoyable, learn-while-you-play apps.

Sibella was short-listed as an USB Social Innovation Finalist in 2016 and become a TechStar Mentor in 2017. Xander Apps have also enjoyed acclaim through Silicon Beach App Awards, AppsAfrica Innovation Awards, and Facebook’s Internet.org Africa Innovation Challenge in 2016.

Natalie Petersen

As our Operations Manager, Natalie is the backbone of our business. She is the most efficient person the world has ever seen.

Natalie ensures things run smoothly and our team is happy. With her expertise in project management, product development, communication and social media, she takes it all in her stride, thanks to her insatiable appetite to keep learning, and her previous position at Brand’s Eye.  

Some experience as a native English teacher in South Korea after finishing her studies at UCT also adds complimentary value to Tribage’s own catalogue of ever-growing educational apps called Xander. 

Software Development Partners, UI / UX, Graphic Design, Animation

Our partners have all been empowered and have become masters of their own destiny to jockey their own ventures and allow them the freedom to better understand all aspects of running a business.

Tribage is a lean operation as we benefit from sharing resources within a bigger group of technology related businesses, therefore our software and sound engineers, design and UI/UX experts are shared within the organization, giving our clients the best quality and experience at the most affordable prices.

How it all started

Tribage was conceived by Sibella & Alan Knott-Craig in January 2013.

Their young family completed an unforgettable road trip across the USA and returned home with a firm conviction that South Africa is an amazing country to live in, and that it offers enormous opportunity in the mobile web application space. 

Technology is the future and for the first time mobile technology is winning the race. Devices and data are becoming more affordable and therefore the need for local content is also becoming increasingly urgent.

Tribage has become the technology partner of choice by specializing in service excellence through creating award-winning mobile applications and providing healthy technology solutions in education and edutainment.
