about
At arqus, we bridge the gap between chaos and clarity, vision and value, numbers and narrative. We believe that every business deserves CFO-level expertise and Corporate Finance Advisory, without the full-time overhead.
Founded by two former CFOs—one with roots in corporate finance consulting, the other seasoned in investment banking—Adrian Michel and Noel Müller bring the depth of executive experience and the agility of hands-on advisors to any company, whether scaling fast or navigating complexity.
We've sat on both sides of the table: driving growth from the inside and advising transformation from the outside. Through Fractional CFO services and Corporate Finance Advisory, we build that bridge that helps your company move from where you are to where you want to be.

Adrian Michel
Partner
I help businesses build the bridge from data to direction. At arqus, I provide fractional CFO services and corporate finance advisory, putting structures in place that scale and support sustainable growth. I'm a finance leader with 15 years of experience in corporate finance, valuation, and strategic management. As CFO of ViCOLLECTIVE AG—the company behind ViCAFE and Vivi Kola—I helped grow and integrate two iconic Swiss consumer brands, building strong finance, HR, and IT foundations for long-term success. Before that, I spent a decade at EY in Zurich and New York, advising clients from start-ups to global conglomerates on strategic planning, financial modelling, M&A, and restructuring. That mix of entrepreneurial and advisory experience lets me bring a practical, data-driven, and people-focused perspective to every project. Outside of work, I live in Zurich with my partner and two kids, and I'm passionate about travelling, food, and good coffee—ideally enjoyed after a challenging workout.

I help businesses build the bridge from strategy to execution. At arqus, I provide fractional CFO services and financial strategy consulting, turning financial insight into actions that drive growth and strengthen foundations. I'm a finance and investment professional with 15 years of experience across investment banking, corporate finance, and CFO roles. I began my career at Credit Suisse Investment Bank in Zurich and New York as Vice President in M&A, handling transactions of all sizes and honing my skills in financial structuring. After returning to Switzerland, I joined Alantra as a Director, completing two IPOs. I then served as CFO at ConReal Swiss AG and have since worked as a venture and fractional CFO for several start-ups, helping early-stage companies build the right structures and make strategic decisions for long-term growth. Outside work, I keep active in and around Zurich, and only slow down for a good meal, a strong coffee, or a weekend getaway with my spouse.
