By Milana Vinn(Reuters) -Boutique investment bank Cascadia Capital is expanding into technology M&A as it hires a veteran technology banker and prepares to open a Silicon Valley office, the firm’s executives told Reuters. The bank has appointed Jonathan Cantwell, previously a partner and head of software investment banking at GP Bullhound, as head of its new technology group. Cantwell will lead recruitment for the new office and build out the firm's advisory practice for companies in the enterprise Software-as-a-Service (SaaS) and artificial intelligence (AI) sectors. Cascadia, led by CEO Michael Butler, a former Morgan Stanley executive, plans to establish an office in Silicon Valley and scale its technology team to approximately 20 M&A bankers. Cascadia Capital currently operates M&A advisory practices in several other industries, including food, beverage and agribusiness; consumer; industrials; and business services.
