Who we are

We created the Nutshell Growth Fund to provide an alternative to traditional global equity managers.


Our solution is a fund which puts responsible investment at its core and does not sacrifice strong performance in doing so.


Our Philosophy

Our investment philosophy is simple. We aim to generate long-term superior growth for our clients by only investing in companies that are both high quality and ethically sound.


Our Process

We invest in a concentrated global portfolio of carefully selected, exceptional companies which have exceeded the highest barriers for inclusion.


We identify these companies through a strict multi-factor screening process. Amongst other things, this takes into account the stability of a company’s earnings and valuation over time, its resilience across economic cycles, and how attractively priced it is.


Intrinsic to our process is analysis of a company’s ESG impact – its environmental, social and governance behaviours – to ensure we only buy companies that, like us, are investing in a better future.


The result is the Nutshell Growth Fund: a high-conviction portfolio of around 35 companies, which we believe will deliver significant outperformance versus our peers and global equity markets.
