Romantic dinner on an iceberg? 'Batcave' in your home? Hong Kong firm turns wishes of China's wealthy into a reality

The past 10 years have flown by for Emma Sherrard Matthew, chief executive of Asia-Pacific for the Quintessentially Group. She started the exclusive concierge service in Hong Kong a decade ago with four people and it has since grown to more than 80 staff.

"At the time our services were unknown, and the idea of outsourcing part of your life. But now we're a niche in the marketplace," she says.

Following the mantra, "the more you give, the more comes back to you", Matthew began marketing Quintessentially by getting to know potential members and "sharing access", telling them how the services would be useful to them. While she admits these specialised services are not for everyone, some were soon hooked.

Recent requests include a romantic getaway to New Zealand where a couple had a private meal set up on an iceberg; arranging a marriage proposal on top of the Sydney Harbour Bridge with one day's notice; and a request from an avid Batman fan who wanted his own "Batcave" in his home.

Quintessentially doesn't just cater to individual members, but has a growing roster of corporate clients and banks that are keen to learn more about their high-end customers. With 62 offices around the world, including Ulan Bator, which opened 18 months ago, and Ho Chi Minh City, in April, there is a wealth of data the tailored service has banked up.
