Mark Evans, the former Goldman Sachs banker, has emerged at Benchmark Capital, the US venture capital firm, where he becomes its fourth general partner in London.

Evans worked at Goldman for 15 years, and his roles included co-head of equity capital markets, where he was replaced by his twin brother Mike Evans, and chairman of the firm's Asian business in Hong Kong. He left his role as Goldman's global co-head of equity research in 1999 after less than a year in the job to pursue entrepreneurial activities.
