Our story

Providing to every breeder and horse lover access to proven breeding. That is what drives us. It’s at the forefront of everything we do.

Discover our mares

In 2018, we set ourselves a goal: to breed exceptional showjumpers. Essentially that’s the goal that every breeder has, but we aimed high and started to figure out what all these top performers have in common. We ended up with 3 markers that most stars share: pure performance, the ability to pass on talent to the offspring, and depth of performance in the damline & family. With that knowledge in mind, we went straight to the source. To Stephan Conter, where we managed to find and buy the holy grail for many breeders. Goya, a young and direct daughter of the unsurpassed Usha van ’t Roosakker and sister of several 5* Grand Prix horses. At Jos Lansink’s, we found a daughter of Ta Belle van Sombeke – a sister of Glock’s London. The icing on the cake was Contara, the mother of Chacco-Blue. Our breeding project had been launched.

Macha is a goddess of the Irish mythology who is often depicted with a foal, symbolizing the importance of mares. She can now be seen as the protector of the mares in our care.

A new milestone for the project was the collaboration with the Devos Family, which led to the expansion of the collection to 36 mares. Each of the 36 matches the markers, some even score the maximum on all 3.

The project needed a name. A title that would emphasize the pivotal position of our mares. The mothers of future sport horses, our MoMs, our Mares of Macha. Macha is a goddess of the Irish mythology who is often depicted with a foal, symbolizing the importance of mares. She can now be seen as the protector of the mares in our care. The genes and talent of our mares are now available to every breeder.

Equine nec-plus-ultra, the home of our MoM’s

Breeding starts with the wellbeing of our MoMs.

Mares are the cornerstone of breeding. We keep our mares surrounded by the best care, in the vast and sunny fields of Northern Italy on a self-managed property. The mediterranean climate allows year round grazing and the large individual stables with spacious paddocks give our equine athletes the comfort they deserve.
