About LEFE

Untill recently, the cost and infrastructure requirements for launching an ETF were prohibitive for small and mid size asset managers. Traditionally, building and launching a new ETF would cost EUR 750K to 1.5M


We are changing that.


Légal & Financier Européen (LEFE) was founded by by Justin Oliver McCarthy in 2015 in order to permit small and mid sized asset managers to enter into the ETF space for a fraction of the going cost and without the need for in-house infrastructure.


In order to accomplish this, we have built a network of competitive fund service providers and asset managers who are willing to service third party ETFs, much like a "white label" solution.


The result enables anyone to create and launch their tailor-made ETF.  


Whether or not you are authorised as a fund manager, we undertake all of the legal work, project management and act as a single interlocutor facing our network of fund service providers, exchanges and financial regulators.  


​Though we focus on servicing alternative investment strategies, we also welcome more traditional investment strategies, in all asset classes.
