Bolliger & Mabillard

Bolliger & Mabillard, widely known as B&M, is a Swiss company that designs and builds roller coasters for amusement parks. Founded in 1988 by engineers Walter Bolliger and Claude Mabillard, it is based in Monthey, Switzerland. The company describes its work as designing rides tailored to each park’s vision and landscape, with each attraction created to suit its setting and the experience its client wants to deliver. B&M’s work spans multiple coaster concepts and ride formats. The company identifies the inverted coaster, dive coaster, wing coaster, and surf coaster among the concepts it pioneered, and also highlights its box-section track. Its portfolio includes custom projects for parks internationally. The company says it has more than 120 installations worldwide and presents innovation, engineering quality, precision, reliability, and long-term durability as central to its approach. B&M serves the amusement industry as a ride designer and builder rather than as a theme park operator. Its website features projects including Tormenta Rampaging Run, a Dive Coaster at Six Flags Over Texas, and names other attractions such as Rapterra and Wrath of Rakshasa. The company also announces its participation in industry exhibitions, including IAAPA events. The supplied material does not identify its ownership, listing status, or current executives.

Bolliger & Mabillard was founded in 1988 by engineers Walter Bolliger and Claude Mabillard. Based in Monthey, Switzerland, the company designs and builds roller coasters for amusement parks. From its beginning, its work has focused on conceiving and engineering rides for individual parks rather than offering a single standard attraction: the company says each ride is tailored to a park’s vision and landscape. The company’s history is closely tied to the development of distinct coaster formats. B&M identifies the inverted coaster, dive coaster, wing coaster, and surf coaster as groundbreaking concepts it pioneered, and also highlights its box-section track. Its website characterizes its design work as iterative, describing projects as challenges to imagine, adapt, and refine solutions to meet partners’ expectations. It also cites numerous patents and decades of engineering experience, though the supplied material does not provide patent names or dates. B&M grew into an international supplier to amusement parks. The company describes its rides as global references and states that it has more than 120 installations worldwide. Its account of its engineering approach emphasizes rigorous testing, precision, long-term durability, and reliability. These qualities form part of the company’s stated value proposition to parks seeking major attractions built for sustained operation. The company’s current public-facing portfolio includes attractions such as Tormenta Rampaging Run, Rapterra, and Wrath of Rakshasa. The supplied homepage reports that Tormenta Rampaging Run is operating at Six Flags Over Texas and calls it the world’s first giga Dive Coaster. B&M also maintains an industry-facing presence through announced participation in IAAPA Expo events. The available evidence does not establish further ownership changes, financial history, or leadership changes.
