Karim Kaddoura is co-founder of Virtuo, the French start-up that’s shaking up car hire. It offers no-nonsense rentals of premium Mercedes not only from airports and train stations but in city centres across France and the UK. The company is expanding quickly, taking away the pain of hiring a car and offering something better than car sharing. Karim’s father owned a dealership and his entrepreneurial journey has been about rethinking our relationship to cars.
