The London-based firm, operating in a number of locations, has agreed to use the tech firm's platform for various functions.
Under terms of the agreement, L&C brings data modelling, portfolio analytics, tailored investment management and performance reporting to its wealth management clients in the UK and overseas.
"The partnership with Addepar enables us to deliver an efficient, flexible and comprehensive picture of each client's unique investments and overall wealth, while staying lean through greater operational efficiency,” Marc Graveney, chief operating officer, London & Capital, said.
Addepar, operating in many countries, has more than $4.5 trillion of assets on its platform. It serves private client investment managers, wealth advisors, private banks, family offices and other customers.
L&C has offices in London, Barcelona and Barbados. It makes a point of serving US expats who otherwise encounter problems in accessing financial services due to regulatory complexity, or people living or investing in the US. In April, London & Capital appointed Kristin Schaefer as head of relationship management for the US family office. Her focus is on the cross-border Americans' client market.
Besides its US-related work, London & Capital has been building a European footprint, as explained to this news service here.
In June last year US private equity house Lovell Minnick Partners agreed to buy a majority stake in L&C.
