Swedish wealth manager Söderberg & Partners has made what it calls a “significant investment” in Artorius Wealth Limited, but has not revealed the size of the investment.
The firm said the deal marks a “major step in its expansion into the UK’s high net worth (HNW) and family office sector.”
Artorius began as a wealth manager in Manchester in 2015 and has been authorised since 2016, according to the FCA Register. The firm’s head office is now in Covent Garden in London and it has more than £1.8bn under management.
It said the move is the first of a number of new HNW acquisitions it plans in the UK. It has previously been busy acquiring stakes in UK Financial Planning firms.
In January 2025 it announced it had taken stakes in three UK Financial Planners.
The group has previously invested in a number of HNW and family office-focused businesses in Scandinavia, growing them through technology and long-term capital support. It said the partnership with Artorius builds on that, bringing the firm’s specialist expertise into the UK market.
Gustaf Rentzhog, CEO of Söderberg & Partners, said: “This investment represents a clear evolution in our UK strategy. Alongside Artorius, we intend to support and fund the acquisition of similar specialist firms and high-quality teams seeking to move away from larger banks and wealth managers, in favour of a more personal and holistic model.”
Paddy Lewis, CEO of Artorius Wealth Management, said: “This partnership marks an important milestone for Artorius and the next chapter of our growth. With Söderberg & Partners’ long-term backing, we can accelerate our expansion while staying true to our belief that wealth management should be crafted entirely around each client.”
Söderberg & Partners was founded in Sweden in 2004 and has a presence in Sweden, Norway, Denmark, Finland, the Netherlands, Luxembourg, Spain and the United Kingdom. It has more than 4,400 employees and £81bn in Assets under Management and Assets under Advice.
