We enable faster, more informed merchandising decisions to help global brands exceed their goals.

Fashion trends & sales trends unite.

The PreWarp namesake comes from the mechanics of weaving fabrics—you set the warp and then weave the weft around it. We are with you optimising every aspect of production before the warp even sets.

PreWarp came about when our fashion industry and computer science brains collided to come up with product launch and pricing optimisation perfection. It’s what we wish we had years ago.

The products we craft guide brands toward faster, more accurate sales decisions so they can stay on top of the most ellusively alluring industry of all—driving fashion forward.
