The departure of long-standing fintech executives from banks in Europe has left their former institutions in need of a new wave of executives to spearhead their ongoing technological innovation.

Marcus Treacher, global head of innovation for payments and cash management and trade and supply chain at HSBC in London, left the bank in late 2015 to launch a consultancy focused on fintech in the transaction banking space. His new venture will aim to help corporate treasuries, banks and professional services firms apply new emerging technologies efficiently, Treacher said.
