A note from the founders

Built just for you

Every company, large or small, should have the power to leverage data in the pursuit of possibilities.

As a part of the LinkedIn data team, our job was targeting the right users for different campaigns in an activity we endearingly called “list pulls”.  Essentially, we stack-ranked users based on specific criteria and a likelihood to buy target solutions. Our teams developed massive tables covering hundreds-of-millions of rows of data including user engagement metrics, zero party and first party alike, to support our segmentation efforts.

LinkedIn became very good at this. But what made it tick was the support of hundreds of data scientists, engineers, and marketers.  It was quickly apparent to us that the enormous benefits of data were just not practically accessible to anyone outside of big tech.

We wanted that to change.

Tresl was founded to give modern online business access to data technologies to transform their growth.  We provide the necessary infrastructure & the data know-how to level the playing field.

We hope you love Segments, as much as we love data.
