Primwest SA

Primwest SA

Primwest SA was established in 2014 as the Swiss investment arm of the Primat family. Didier Primat, a grandson of Marcel Schlumberger and former major shareholder and board member of Schlumberger Limited, founded the holding structure. The office now operates under Bérengère Primat as president of the parent entity. Primwest deploys capital through direct co-investments, SPVs, hedge funds, private credit, private equity and real estate. Confirmed asset classes include early-stage venture positions in AI/ML, biotech and consumer technology alongside buyout and growth equity. Geographic reach spans North America, Europe, Asia, Africa, the Middle East and South America. Family real-asset holdings include Primland Resort in Virginia and Domaine des Etangs in France. The team includes Chief Investment Officer Andrew Maclean and Managing Director Simon Haworth. No public headcount or AUM figure has been released. Adjacent vehicles comprise Fondation Opale, Fondation Didier et Martine Primat and the Menil Collection in Houston. No operational events from the last 24 months appear in public records. Primwest functions as a direct-investment vehicle rather than a fund-of-funds platform. Its mandate emphasizes early-stage commitments alongside real-asset and credit strategies, with family members holding seats on the investment committee.
