About

We are a financial investment advisory firm focused on delivering trading strategies with attractive performance to our clients.

The story of Keynum Investments began in 2010 at the Forecasting Financial Markets international conference on quantitative finance. Hans-Jörg von Mettenheim and Sylvain Barthélémy shared the belief that mathematical and statistical methods do generate long-term sustainable returns. They started to develop quantitative trading strategies and a fully automated trading advisory system in 2013.

Hans-Jörg and Sylvain founded Keynum Investment in 2017. The company now provides quantitative trading strategies for banking institutions, funds, funds of funds, family offices and high net worth individuals.

Keynum Investments is now a French registered Financial Investment Advisor, regulated under the Monetary and Financial Code and the AMF General Regulation. The company is member of the CNCIF and is registered at the Orias (under the number 17005970 – www.orias.fr).

In 2019, the company signed a partnership with Sanso Investment Solutions (Sanso IS), a French asset management company based in Paris (sanso-is.com), to facilitate the access to Keynum Investments recommendations through a Sanso IS UCITS fund, launched in November 2019.

Most of us have been involved for several years or even decades in economic consulting and quantitative investment strategies.

A Network of Researchers

We work with an International network of researchers, practitioners and software developers. Most of us have been involved for several years or even decades in economic consulting and quantitative investment strategies.
