Alliance Sponsors

We’d like to highlight that several companies support us here at IART. Some offer equipment for testing purposes, while others provide generous discounts to our members. Below is the current roster of companies that support IART.

The following are companies that provide equipment for testing purposes.



All racquets that are reviewed on the Alliance website are tested on a Babolat RDC. That unit is provided to the Alliance website and used extensively for all testing purposes.


Wilson provides us with a BAIARDO constant pull stringing machine. The BAIARDO has established itself as a solid machine since its introduction, especially when it comes to tournament stringing.


The subsequent companies offer discounts on strings, grips, and various other products.
