Our approach

Sienna Capital offers a differentiated proposition to alternative investment managers: long term patient capital in exchange for attractive financial terms and a role as a value-added partner.

Our investment decisions are based on a rigorous and consistent process:

  •   Identify attractive investment opportunities (comprehensible asset class, large and growing addressable market)
  •   Identify and partner with talented managers applying a disciplined selection criteria and a thorough due diligence process
  •   Negotiate favourable terms with managers (boost returns by obtaining reduced fees, preferred economics and other benefits for investors)
  •   Provide a value added ecosystem, for example by helping managers raise money and attract talent


The net asset value of Sienna Capital will represent up to 10% of the overall net asset value of GBL in the medium-term or approximately €2 billion (versus €1.3 billion as of 31/12/2018).
