It has emerged that Niall Cowley closed the agency after it was hit hard by public sector cuts.
Cowley is now working as a senior consultant at Media Consulta in Berlin.
He said: 'Bright Young Things lost nearly all its public sector clients in one fell swoop after the change of government, so we had to stop trading.'
Cowley, who took the job at Media Consulta in August, is working for the senior management team of the international unit.
