Turning Hong Kong into a playground for collaborations

growbro™ builds collab events, merch drops, and cross-promotion cup sleeve campaigns that turn everyday spaces into experiences

Collab Event Marketing

We design and run experiences that bring real people into your space — from social runs and launch parties to workshops and cultural events.

Collab Merchs

Limited-run collab merch that people actually want to keep — tees, caps, towels, cups and tote bags. Accessible, meaningful and designed for everyday life.

Cup Sleeve Marketing

Cross-promotion cup sleeves that turn every coffee into a touchpoint — complete with QR codes, offers and trackable conversion.

Our Story

What started as casual morning runs and coffee gatherings evolved into something bigger. We noticed how powerful it was when different communities came together — the energy, the creativity, the unexpected connections.

We also noticed that beautiful experiences often came with high price tags, keeping them out of reach for many people and small businesses. So we asked ourselves: what if we could make collaboration the default, not the exception?

We connects brands, venues, artists and communities across Hong Kong, design events that feel authentic, create merch people actually want, and turn everyday coffee cups into marketing opportunities. All while keeping costs accessible and creativity high.

Let's build something together

Whether you're a coffee shop, restaurant, artist, brand or community organizer — we'd love to explore how we can collaborate.
