Partner and CEO
Before starting xlwings, Felix was a director at UBS Global Asset Management in Zürich. In his most recent role as product manager, he was responsible for the development of an internal multi-asset portfolio construction tool. The application analyses and optimises clients' strategic asset allocation and is key to the bank's relationships with institutional clients as well as for product construction.
Felix left UBS in 2014 to build a solution that could bridge the gap between legacy Excel/VBA technology and the fast-moving, modern Python world with its ever-more evolving ecosystem: xlwings. Fast-forward a few years, xlwings is a thriving open-source project and, among others, very popular among hedge funds, asset managers and banks.
Along the way, Felix built our consulting business, advising financial services clients on how to integrate Excel and Python in a sustainable way. Today, consulting, training and education around xlwings, together with xltrail, our Excel version control product, are the foundation of the business.
Felix holds a Master's degree in Finance and Economics from the University of St. Gallen (HSG). Felix is a CFA charterholder. He is based in Zürich, Switzerland. Please get in touch if you need help bringing Excel and Python together:email@example.com
