Meet the Jennings
Steve Jennings
Co-Founder & Chief Executive OfficerBorn in Hull and built for the frontier, Steve Jennings has spent three decades doing things first. As a professional cyclist, he founded Maxim Sports Nutrition (growing it into Europe's leading active lifestyle nutrition brand, acquired by Norwegian conglomerate Orkla Foods) and, in 1992, introduced Ergomax C150 at the Barcelona Olympic Games: the world's first creatine monohydrate supplement. From there, Steve went on to become a founding member of PepsiCo's global Good-for-You nutrition innovation team, co-founded IOVIA (a brand participation platform that worked with IKEA, Unilever, LEGO, Nike, and Volvo), and was an entrepreneur in residence at Lund University in Sweden.
Now based in Belgium and most creative on his race bike through the roads of Flanders, Steve has brought all of that experience back to the molecule he helped launch. He co-founded Jenerise with his daughter Rachael because the science had long outgrown the gym, and someone who knew the category from its very first day needed to say so.
Rachael Jennings
Co-Founder and Chief Brand OfficerRachael Jennings built her career at the intersection of creativity, community, and growth. With a background spanning education, event management, and marketing, she co-founded Vivero, an outcome-driven innovation studio where she pitched and worked alongside brands including Spotify and LEGO. During the pandemic, she launched a social audio start-up, finding new ways to build connections at a time when the world had gone quiet.
But it was a personal turning point that brought her to Jenerise with full conviction. A Hashimoto's diagnosis led Rachael deep into the science of energy metabolism, hormonal health, and the chronically underserved conversation around women's wellness and creatine kept appearing at the centre of it. She joined her father, Steve, not just as a co-founder, but as someone who understood from the inside what was missing. As Chief Brand Officer, she leads Jenerise's education platform, the Seizing the Years podcast, and the weekly community newsletter, as well as all our branding and touchpoints, on a mission to take creatine from niche to necessary for millions of people who need it most.
