Nobody is a stranger to WhatsApp and Facebook in this era of social media networking. Meet the co-founder and CEO of WhatsApp, Jan Koum. This tall man with the unshaven look has seen some really tough times growing up. Koum was born to Ukrainian parents in a small village outside Kiev.
His mother was a housewife and his father was a construction manager involved in building hospitals and schools. The house did not have hot water and his parents seldom spoke on the telephone, for fear of their conversations being intercepted by the State.
