Why work with us

Most agencies resell media through intermediaries. Hypertree holds direct buying relationships with every major media owner in Hong Kong — MTR Corporation, KMB, Citybus, Hong Kong Tramways, TVB, ViuTV, JCDecaux Transport, Bravo Media, and Asiaray. This means better rates, priority inventory access, and faster turnaround for our clients.

We handle everything under one roof: strategy, creative production, media planning, buying, and post-campaign reporting. No layered agencies, no coordination gaps. One team, one brief, one budget.

For international companies entering Hong Kong, we remove the complexity of navigating a fragmented media landscape across OOH, broadcast, and digital channels. For Mainland Chinese businesses targeting Hong Kong consumers, we offer integrated cross-border campaigns combining physical OOH with Xiaohongshu and WeChat marketing — a capability unique to our agency.

We deliver a tailored media plan within 24 hours of enquiry, produce all creative in-house across English, Traditional Chinese, and Simplified Chinese, and report on every campaign with verified reach, frequency, and engagement metrics.
