Harte-Hanks will combine its other marketing offerings in Europe with Information Arts to create multichannel integrated lead generation and lead management programmes.
Information Arts works for clients including Shell, Cisco and Vodafone and was founded by Lawrence and Selby in 2000, expanding into Europe in 2004.
Its Omni database blends information from leading European data suppliers.
It started working with Harte-Hanks in 2007, for the US company to acquire Information Arts at a later date.
Having seen that agreement bear fruit, Lawrence said: "Harte-Hanks is an impressive multinational business with a prolific client list that spans a diverse range of industries and locations, so becoming a part of Harte-Hanks is a natural step forward.
"Information Arts will continue to work from the position of providing the best quality independent marketing data and insight, and we expect to continue to see the business grow organically by attracting top name clients."
