The Evolution of Multidimensional Modeling
Tesser's roots go back more than four decades, to a generation of innovative software that challenged the way people built financial models and analyzed complex business data.
The journey began with Javelin in the mid-1980s and continued through Lotus Improv, Quantrix, and ultimately Tesser. Along the way, the technology evolved from character-based desktop software to graphical applications— and finally to a cloud platform built specifically for multidimensional modeling and analytics.
From Javelin to Tesser
Four decades of innovation in multidimensional modeling
One idea. Four decades. Still evolving.
From character-based financial modeling to graphical desktop software and now cloud-native multidimensional analytics, the technology has continually evolved around one fundamental idea:
Make complex multidimensional data easier to model, understand, and use.
Four Decades. One Continuing Idea.
The technology has changed dramatically: from character-based interfaces to graphical applications, from desktop software to the cloud.
But the underlying idea has remained remarkably consistent:
Give people a better way to model, understand, and work with multidimensional data.
That is the idea that connects Javelin, Lotus Improv, Quantrix, and Tesser - and it continues to shape where Tesser goes next.
