About ONYX

A solid past. A brighter future

We are a leading hotel management company that combines the expertise of a truly global executive team with the hospitality excellence for which Asia is renowned.

We pride ourselves on an open, approachable leadership style and recognise that the relationships and mutual trust established with our property partners are the fundamental basis for the success of any hotel management company. Your needs and concerns are our driving force.

ONYX offers a wide portfolio of hospitality brands, including the market-leading Amari brand of hotels and resorts, Shama serviced apartments and the midscale OZO hotels.

Our company was founded by the key leaders who created the Amari brand, in order to manage the operations and development of Amari, as well as our other brands. Through these brands, we will strengthen our ability to operate across the quality spectrum, from value-oriented products through mid-scale and luxury.

We also established ONYX Greater China Corporate Office in order to create a presence in the market. Based in Shanghai, our Greater China team will focus on expanding its operations beyond the domestic market and swell its capabilities in the hotel, resort and serviced apartment sectors.
