Zak Marks is the Co-Founder and CEO of Kitt Medical, a startup transforming how emergency allergy response is delivered in schools & qualifying businesses. Diagnosed at age five with severe allergies, Zak lived in constant anxiety - adrenaline pens were hard to carry, easy to forget, and expire quickly. He came up with the idea for something “like a defibrillator for allergies”, during his final year at university, After graduating in 2020, Zak was joined by co-founder James Cohen. They officially launched Kitt Medical in 2023, offering wall-mounted kits alongside a subscription supply of adrenaline auto-injectors, expiration-monitoring software, and CPD-accredited training. In 2025, Zak & James pitched on BBC’s Dragons’ Den, securing investment from Deborah Meaden and Steven Bartlett. Today, Kitt Medical operates across 2,000+ UK locations, working with organisations from Compass Group to Merlin Entertainments, Siemens Energy to Center Parcs, training 35,000+ members of staff, and saving 25+ lives."
