What Yellow Brick Capital Advisers does
Yellow Brick Capital Advisers is a London-based, founder-owned family office established in 2007 by Johnathan Kol-Bar, operating across two principal verticals: a London-centric real estate development portfolio and an agricultural technology ("Innovations") investment portfolio. The real estate platform, branded Yellow Brick Estates, owns and operates 13 named assets including the flagship Pelican London Hotel & Residence (a 222-bed hotel, HMO and office complex adjacent to St. George's Hospital NHS at 98% occupancy), Whetstone Square, Whetstone Gardens, Battersea Hope, Pelican Woolwich, King House, Kensal View, The Poet's Corner Collection, Dernford Reservoir, Lakehurst Park, Nataly Gardens, and Essex Wish, alongside the Yellow Brick Clinics healthcare property sub-brand. Across the portfolio the firm reports £144M of Gross Development Value delivered, 190 units completed, and 11 projects developed.
The Innovations vertical, branded Yellow Brick AgTech, comprises active and passive minority investments in early-stage agricultural software and hardware companies, including Phytech (plant growth sensors, 2011), I-Plant Nutrition (2022), Smart Sparrow (adaptive education technology, 2023), PlantMetrics, Haskelberg Advanced Technologies, Terminus (2025), and Julia: The Officium (AI software for agriculture, 2025). The firm supports these with an in-house team of software engineers and data scientists that develops bespoke software solutions for major agricultural organisations, effectively functioning as an internal product capability rather than a third-party vendor relationship.
The business model combines recurring hospitality revenue (Pelican London hotel and HMO operations), project-driven real estate development receipts (sales and rentals across the London and Surrey pipeline), and capital returns from the AgTech minority investment portfolio. Distribution is exclusively direct, via relationships with global investors and ultra-high-net-worth families rather than third-party channels. The team spans over 50 members across London, Europe and Asia, with the founder retaining the Chairman role and operational control of the firm.
