Exegy and Rival systems

Anyone has experience using Rival systems (https://www.rivalsystems.com/) or Exegy (https://www.exegy.com/) products?

 

Rival has a good pedigree. Rob d'Arco, the CEO, is solid.

 

I am interested in using them, but which brokers offer them?

 

Interactive Brokers. They may provide access to Rival Systems or Exegy platforms, but better confirm directly with them.
