Robey Warshaw LLP is a boutique investment bank based in London. The firm was founded in 2013 and is led by investment bankers Sir Simon Robey, Philip Apostolides, and Simon Warshaw. With less than 20 employees, it has advised on some of the largest corporate mergers and acquisitions since 2015. According to The Observer, banking experts have attributed Robey Warshaw's early success to the connections of its founders and its ability to remain discreet during negotiations owing to its small size. The Telegraph highlighted the firm's "personal approach" favoured by corporate executives.
