Yeah Evolve's essentially a corporate gym that uses these big fighters' name to lend credence to the brand and it's more or less a passion project by a millionaire businessman. The average Singaporean probably couldn't afford the fees there; it's really more catered to expats, those earning high wages and their kids. It's like those white collar boxing gyms in Manhattan that specifically cater to guys working in Wall Street. They'll keep a small stable of highly ranked pros that do their training camp there in order to maintain their authenticity.
Some of the bigger names (Aoki, Askren, Saffiedine, Hendo and Dos Anjos) only fly in for part of their training camp and/or to teach the occasional seminar. Although to be fair, they do have Heath Sims, Gilbert Burns' brother and a bunch of Lumpini champs teaching full time.
