Born in Belgium circa 1967, Bart van Malderen is a self-made Belgian industrialist who has twice built and successfully exited a multi-billion dollar empire in the niche, but high-volume, hygiene products industry. His career was destined for this sector; his father founded the family business, Ontex, in 1979, which specialized in manufacturing disposable hygiene products.

Van Malderen grew up immersed in this industrial world, and by the age of 30, he was already at the helm of Ontex. His background is one of intensive, long-term industry experience, having worked for 30 years in the diaper business, 20 of which were as CEO. This deep, granular knowledge of manufacturing processes, logistics, and private-label retail relationships became the invaluable asset he would leverage to build his second, even more successful, enterprise.

Bart van Malderen's career is marked by two massive successes. Phase 1: Ontex (1980s–2007). As CEO, he transformed the family business, leading 26 strategic acquisitions and growing Ontex into a global player. He took the company public but later managed its sale to private equity players before leaving in 2007, securing a significant initial fortune. Phase 2: Drylock Technologies (2012–Present). After his non-compete clause expired, Van Malderen immediately returned to the industry he knew best. He founded Drylock Technologies in 2012, deliberately re-entering the diaper and feminine hygiene market.

He built Drylock with a laser focus on innovation and efficiency, often achieving results before the market's bigger players. Drylock focused on becoming virtually indispensable to supermarket chains by producing high-quality private-label baby and incontinence diapers. He financed Drylock primarily by selling his Ontex shares and shares of VGP (a family-owned real estate developer), boldly investing millions to grow Drylock to a turnover exceeding €1.2 billion in just over a decade. His philosophy is simple: be relentlessly efficient and first-to-market with innovation (e.g., paper-bag packaged diapers).

Bart van Malderen’s social impact is structural, stemming from the economic stability created by his massive industrial enterprises. Drylock Technologies provides thousands of industrial jobs across its nine production sites in Russia, Italy, Brazil, and the US. His focus on low-cost, high-quality private-label goods also contributes to household affordability for essential products like diapers.

His personal philosophy highlights efficiency and less resource-intensive business practices. He realized that a trip of several days could often be replaced by a single hour-long call, leading to a more efficient, less taxing work environment. His son, Jules, is actively involved in Drylock, ensuring the entrepreneurial legacy continues into the next generation.

Bart van Malderen maintains the pragmatic, sharp style of a successful European industrialist. His attire is functional, professional, and high-quality, favoring business attire suitable for visiting his manufacturing plants across multiple continents. His aesthetic is one of confident efficiency and mastery over complex industrial processes.

His lifestyle is secure and international, defined by his residences in Belgium and his investment interests. His luxury is the strategic autonomy provided by his immense liquid wealth, allowing him to be his own boss and invest aggressively in his passion: the hygiene products industry. His commitment to efficiency extends to his personal life, viewing his wealth as a tool for creating generational security and continued entrepreneurial endeavor.
