Milton Keynes-based Thesaurus Computer Services Ltd, which competes with market leader Synapse Plc in the IBM software support market, claims to have recruited its 35th customer since it was established one year ago, over half of which have moved over from Synapse according to managing director Stephen Mead; Thesaurus, which had sales of nearly UKP1m in its first year of operations, says it does not charge a retainer for its services, a practice it sees dying out across the industry within two years.
