Leonsis Family Office

Leonsis Family Office is a Mallorca-based family office founded by Deniz Demirdizen in 2012. It manages international mandates for a small circle of clients, focusing on independent investment advisory, wealth structuring and strategic allocation, with particular activity in residential and commercial real estate. The firm is relevant for founders or fundraisers seeking a discreet family-office allocator focused on long-term capital preservation and growth rather than a conventional venture capital investor.
