We are a privately owned, independent firm based in London, UK. Ben Beneche and Ramesh Narayanaswamy, are seconded to Eschler Asset Management LLP to manage the Tourbillon Investment Partnership. The Tourbillon Investment Partnership is a long-only public equity fund investing in between 15 and 25 businesses globally using a fundamental, absolute-value oriented approach. We approach investing through the lens of long-term asset 'ownership' rather than stock 'trading', and invest opportunistically across countries, sectors and market capitalisations.We focus on three mental models which we believe reflect deep truths that have endured over decades: fulcrum assets, symbiotic loops, and outlier management.
