Global Team
Our team of partners, consultants and advisors work as one global team, operating from the London hub which services UK and European clients, and Hong Kong, managing clients across Greater China and South Asia.
The two hubs are designed to meet the growing symbiotic relationship between Asia and Europe, especially in the creative and technology sectors.
For projects outside Asia and Europe, we have relationships with likeminded advisors in North and South America.
