• Sandaire: London-based multi-family office offering discretionary investment management and family office services to UHNW clients. Closest UK boutique competitor with overlapping outsourced family-office and investment oversight offering.
• London & Capital: London-based boutique wealth manager and multi-family office providing investment advisory, wealth structuring and family office services to UHNW clients. Direct UK boutique competitor with overlapping offering.

• Kleinwort Benson (Societe Generale Private Banking): UK private bank (now part of Societe Generale) where Sally Tennant was CEO 2011-2014. Direct competitor for UHNW and family office mandates in the UK market, with substantially larger balance sheet and product set.
• Quilter Cheviot: UK discretionary investment manager within Quilter plc focused on HNW/UHNW clients, charities and family trusts. Comparable in investment oversight and advisory, with broader product reach.
