Helping telcos grow revenue since 2009

Our Story

Our mission is to enable traditional operators to thrive in a digital world.

Sifox was founded in 2009 by a small group of telecom industry veterans who believed that operators deserved better IT options than just a patchwork of VAS “point solutions” built on outdated technology. With the aim of helping telcos grow revenue, Sifox has spent over a decade developing a platform capable of meeting the rapidly evolving needs of today’s operators. In that time, Sifox has grown to over 100 employees spread across five continents.

Today Sifox is a trusted technology partner and innovation engine for leading telecom operators like Beeline, Megafone, Safaricom and Tele2. Sifox helps traditional MNOs grow RPU, retain customers and compete with OTT with modern, innovative services that boost subscriber value and network usage.  And thanks to our transparent revenue-sharing model, our clients know that we are just as invested in their success as they are.

Core Values

Experimentation is key to innovation. We would rather try and fail than not try. 

Smart and committed

We trust one another to perform at our very best and demand high quality results.

Thoughtful and driven

We go beyond our job description and constantly improve our competence.


Instead of bureaucracy, we make decisions based on data and move ahead.

Open and honest

We tell it like it is without fear of looking stupid and strive to do the right thing.
