Maximilian Roskosch

Independent Strategy and M&A Advisor | Co-Founder & MD @HelloBonnie

Hamburg, Germany


As a highly experienced engagement manager with over six years of experience at EY-Parthenon, I have developed a strong track record of delivering successful strategy and M&A projects for clients in the financial services and technology sectors. I have worked with C-level and upper management clients in a variety of industries, including payments, banking, software, private equity, and retail, and have led more than 30 projects covering topics such as growth strategy, product strategy, and G2M strategy. My ability to manage teams effectively, conduct thorough due diligence, and advise on post-merger integration has earned me a reputation as a trusted and skilled professional in the field. Since October 2022 I am in the process of building up my own fintech startup in the space of employee benefits.
