About P.S.I.

Success made by Performance Sales International!

40 years ago, when Performance Sales International was started in the USA, we could not have imagined the history this brand would write. We have always pursued the principle of selecting the auction collection from our own, home-bred horses, guided by our experience and knowledge and will continue to do so in the future.

Horses sold at the P.S.I. Auction are regularly found in the results lists of international shows and tournaments. Yet we are not only known for producing future equine talent, the P.S.I. brand has strongly shaped the competition scene in Europe whilst always highlighting the trusting partnership between horse and rider.
