We provide our readers and customers with facts and fact-based analysis – not opinions.

We think a good analysis contains less words and more numbers & graphs – so we work hard to improve the visualisation of complex data.

Our analyses

Analyses done for our customers are by nature confidential – even though the actions taken based on them often lead to products or strategies that become very visible.

We are, however, writing many of our analyses without a customer in mind: Since we started our business, more than 50 papers have been published as public industry analyses – free for anybody to download and read.

In a few cases, these analyses have been sponsored:

Increase loyalty. Increase revenue. Reduce SAC/SRC. Is the combo possible?

Wi-Fi – the last piece of the customer retention puzzle?

ARPU improved when data usage growth slowed down


In addition, there’s Tefficient’s blog. It’s lighter and, occasionally, a bit less balanced.
