Investment thesis
Brookstreet pursues a 'Hybrid Growth Capital' strategy aimed at closing the gap between reported IRR and realised DPI, emphasising duration discipline, defined exit pathways, and realised value. The firm targets equity-funding-gap opportunities (notably Series A/B and later growth) with clear up-round and exit plans, spanning scale-ups through buyouts and consolidations. Its investment focus centres on data-driven AI applications in four themes: digital transformation (software, IoT, cybersecurity, robotics/drones), energy transition (renewables, storage, circular economy, sustainable technologies), longevity (personalised medicine, diagnostics, healthspan/lifespan tech), and defence technology (secure communications, threat detection, autonomous systems, space and critical infrastructure). Brookstreet operates globally across the USA, Europe, MENA, and Asia.
