• Learn about us

Our ambition: Direct Marketing performance.
Our team: some of the best existing Test & Learn experts.
Our success: yours.

Teanler is the leading independent contributor to Test & Learn success stories worldwide.





Our mission is to make Test & Learn accessible, without any statistical knowledge and without having to invest hundreds of thousands of euros in consulting fees or proprietary algorithms.
Our main objective is to increase the performance of your direct marketing campaigns, and we will constantly work with you in that direction until the goal is reached.
We developed a set of sophisticated statistical models which can be leveraged in almost every kind of situation with very little adjustment, and which will maximize the probability of success of your test campaigns.
Naturally, your satisfaction is our first priority and we always stick to 4 core values:

   Transparency

We will never sell you something that will not work. If Test & Learn cannot be implemented in your specific environment (lack of contacts, insufficient customer data, …), we will always let you know before it is too late.

   Reliability

Extreme precision and accuracy are two key elements when it comes to playing with Test & Learn, mainly because a small mistake in the process sometimes lead to a big impact in the final results. With Teanler on your side, you can be sure that everything will be carried out with the utmost professionalism: we’re constantly hunting for perfection, and we’re proud to say that we achieve our goal most of the time.

   Confidentiality

We know the value of your data and other corporate information. We will never ask you for any confidential customer info (all the data in the files we receive can be sanitized) and we will never disclose any kind of information regarding your company.

   Reactivity

In some cases, time really matters. We will always do our best to provide you with the service you required, answer your questions or solve your problems as quickly as possible.
