Eva Maria Bucher-Haefner is a Swiss billionaire heiress and investor. Her immense fortune stems from her former stake in the U.S. IT management software maker, CA Technologies (acquired by Broadcom in 2020), and her family's ownership of the AMAG Group (a major Swiss car dealer). Born circa 1957, she is the daughter of the late Walter Haefner (d. 2012), who was the world's oldest billionaire at 101.

Eva Maria inherited half of her father's stake in the software company (held through Careal Holding AG) and an equal share in AMAG, alongside her billionaire brother, Martin Haefner. Her career is defined by asset management and her deep personal commitment to the equestrian world, a passion she inherited from her father.

Eva Maria Bucher-Haefner's financial strategy involved consolidating her inheritance and focusing on her personal passions. She sold her stake in the car dealer AMAG to her brother Martin in late 2018, simplifying her investment portfolio.

Her greatest personal venture is the ownership of Moyglare Stud, a 500-acre horse farm in Ireland purchased by her father in 1962, which is home to around 100 horses. Moyglare Stud is renowned in the equestrian industry, breeding and raising top-class thoroughbred racehorses. Her wealth is primarily secured by the immense liquid capital generated from her share of the family's stake in CA Technologies (which was sold to Broadcom), confirming the profitability of her father's early software investment.

Eva Maria Bucher-Haefner's social impact is structural, stemming from Moyglare Stud's role in the global thoroughbred racing and breeding industry. Her continued investment supports the equestrian sector in Ireland.

Her personal philanthropy supports various educational and community initiatives, often tied to horses and animal welfare. Her career provides an example of a corporate heir leveraging immense inherited wealth to become a world-class patron and steward of the equestrian industry.

Eva Maria Bucher-Haefner maintains the elegant, composed style of a Swiss heiress and equestrian patron. Her attire is consistently high-quality, favoring classic designer wear, often blended with functional riding apparel. Her aesthetic is one of refinement and quiet, established affluence.

Residing in Zurich, Switzerland, her luxury is the immense security and autonomy derived from her multi-billion dollar fortune. Her life is dedicated to the stewardship of her father's software fortune and her profound passion for thoroughbred breeding and equestrian sports.
