Skills and Experience

Isabelle founded Sumerian Partners in 2013 after she was approached by several close friends and philanthropists who recognised that her asset management experience – backing sound management teams, providing hands-on business support and structuring the appropriate financing – could help them achieve greater lasting impact.

Isabelle started her career at Lehman Brothers in equity research and was then a Principal at Advent Venture Partners, a venture capital firm focusing on technology in the UK / Europe. She was actively involved in sourcing, investing and sitting on the Boards of these companies, providing strategic advice with regards to overcoming challenges to growth, positioning them in the market and ensuring successful exits. After Advent, Isabelle was a portfolio manager at LK Advisers, the Mittal Family office, where she was one of three investment professionals responsible for investing in public equities and private companies, largely in developing markets.

Isabelle holds a BSc (Finance) from Lehigh University.
