Flemyn

Flemyn was established in 2013 by Luigi Gatti Bonati, previously Head of Family Office Group at BAML, and Mark Valentine, formerly Managing Director at Citi. The firm functions as both a family office and a co-investment vehicle focused on real estate. Flemyn deploys capital through direct co-investments and SPVs in real estate, private equity, and hedge funds. Its strategy covers residential, hospitality, office, life sciences, and mixed-use projects. Confirmed holdings include Virgin Hotels Edinburgh developed with Sir Richard Branson and William Pears Group, Botanical House in Croydon executed with Amro Partners, Onda Residences in Miami, and Keynes office asset in Amsterdam. The firm maintains exposure across Europe, North America, Asia, and Africa. No public data exists on team size or additional offices. Flemyn oversees direct asset management for families and maintains interests in philanthropic structures. No operational events from the last 24 months appear in available records. Flemyn operates through a hybrid model that combines family-office mandates with co-investment partnerships alongside institutions such as William Pears Group and Amro Partners, enabling access to specific projects without reliance on external fund vehicles.
