About Us

Keystone Capital is a wealth advisory boutique founded by Samik Mukherjee and David McLellan. After many years working for well-established wealth managers they realised that their clients would benefit greatly from the services of a wealth adviser who could seamlessly combine the traditional values of relationship led advice with the latest developments in the world of finance. Encouraged by their clients and peers, they decided to set about making this vision a reality.

Keystone provides professional and impartial advice on structuring and managing wealth to meet our clients’ specific objectives. This may be planning for retirement, protecting assets for future generations or simply trying to optimise returns on investments. Whatever we do, we always put our clients’ interests first and foremost and find solutions that are tailored to their individual needs.

Keystone offers a service proposition that is essentially a hybrid between a Private Bank, an Independent Financial Adviser and a Multi Family Office, adopting some of the best elements from each of them. We work closely with a handful of carefully selected asset managers, financial service providers and other industry professionals to bring a bespoke and cost efficient solution to the table every time. With no external shareholders to satisfy, we only ever act for our clients and always in their best interest. Samik and David have drawn upon several decades of experience in the wealth management industry, working for some of the most prestigious names, to help define the Keystone service proposition.
