ResponseTap came about over a few beers in a university bar, and a conversation between Ross and Richard about the disconnect between online and offline customer journeys. Within two years, they had launched their campaign level tracking project, the first in Europe to be integrated with Google Analytics. Two years later and visitor level tracking was live, the business had 100 customers and ResponseTap had joined the Telegraph's Tech Start-Up 100 most promising techology start-ups in Europe. Today, having raised £4m in funding, the business has 80 staff, 50 new customers every month, offices in London, Manchester and Atlanta, and billions of web visits, phone calls and associated transactions processed every day.
