Grant Milne, Gordon McAndrew, David Henderson and Ian Smith will join over the next few months. The raid on Deutsche follows Investec's integration of Williams de Broe and its move to new headquarters at Quartermile in Edinburgh last December.
Mr Milne was managing director of Deutsche' s office in Edinburgh until last year and a board member of the UK business. At Deutsche he was responsible for the management of over £150 million of assets. He will start at Investec next month.
Mr McAndrew will not start at Investec until early next year, having until now headed Deutsche's discretionary management team in Edinburgh and sat on the UK investment committee.
Mr Henderson has been an investment director in DAWM's Edinburgh office for 10 years. Ian Smith has been an investment director at DAWM for eight years. He and Mr Henderson will both start in November.
Murray Mackay, Investec's director in Edinburgh, said "We are tremendously pleased to welcome four exceptional wealth management professionals."
