Our Vision
We are a small team of hard-core quantitative experts, with many years’ experience in top-tier NL banks, insurance companies and other financial institutions. We help financial institutions with the development and prototyping of new products/models as well as the validation/improvement on existing models.
The founder, Dr. Fang Fang is a senior Quant with 15 years’ experience in risk and pricing model development and validation. She holds a PhD in Applied Mathematics from the Delft University of Technology. Her first paper on her original numerical method, the COS method, has gained 800+ citations since 2008. The method is also popular among practitioners around the world. Her research activities did not stop after she entered the financial industry as a quant.
This firm was founded in summer 2016 as F-squared Quant and later in spring 2018 transformed into FF Quant B.V. Our scientific yet practical attitude in research and model development is what we are particularly proud of as a professional quant and development team. In 2020 we started the tooling business line next to the consultancy business, aiming to serve our clients even more efficiently with readily-available tools and prototypes.
