Serial entrepreneur Collins is well on his way to making his third fortune in 15 years. He was Sarah Newman's partner at Needahotel, which was bought for €60m in 2006. The former Revlon salesman owned about 30pc of the business.
He re-invested in online insurance broker 123.ie, making about €27m when it was sold to RSA in 2010. Now Collins is shaking up the home energy market through his Prepaypower business, which pretty much does what it says on the tin. Sales have topped €80m and he owns around a third of the business.
There's a bit of glamour too. Last year Collins married Luisa Zissman, a former Celebrity Big Brother contestant in a lavish wedding in France. He bought a €7.5m house in north London.
