## About

Yellow Brick Capital Advisers was established in 2009 by Johnathan Kol-Bar. The firm grew directly from the Kol-Bar family’s existing real estate development business and ag-tech activities. It now serves as the pooled investment vehicle for several additional ultra-high-net-worth families. The firm allocates across private equity, sustainable real estate, natural resources and digital assets. It executes through direct co-investments, SPVs and fund-of-funds commitments. Confirmed holdings include multiple London residential, mixed-use projects such as Poet’s Corner and Kensal View. All activity remains inside Europe. No public figure for assets under management exists. The team includes family members Fenella Kol-Bar and Guy Kol-Bar plus external executives Johan van Zyl and Joshua Olshin. Yellow Brick Estates operates as the dedicated real estate development arm. The firm maintains an integrated operating company structure that combines family capital with in-house development and engineering capabilities. This model allows direct control over project execution rather than reliance on external managers.
