Elaborate boxes, star guests and detailed planning help firms win the networking game
Planning for next year's event starts the moment the Sevens has stopped. Ideas are mulled over and big budgets set long in advance.
This is coveted territory, and the competition for the best box is almost as tough as the action out on the pitch.
The Sevens is industry's time to showcase itself to its peers - and to the world.
All that fun is a serious business when the underlying agenda is to position the company's brand in the best light possible.
The main boxes went for themes: an aviator one for Deutsche Bank, complete with leggy flight attendants; CLSA went for a cool landing, with an ice statue acting as a conduit for drinking near-frozen vodka; Merrill Lynch had an 'On the Piste' apres ski theme.
Standard Chartered decided the best theme was former players. In its box this weekend it assembled a formidable squad of greats - Francois Pienaar, Jonah Lomu, Gavin Hastings and Jason Leonard, chaperoned by Phil Greening. Greening, a former Lion, is now based in Singapore with the bank, in a sponsorship and community rugby role.
