In the article it discusses what he does money-wise these days by the way. He's heavily into cooking. He's trying to get his Sri Lankan curry paste into Harrods as we speak (really!). At one point, he went back to Sri Lanka for a year to learn how to seriously cook.
Not all of my discussion with him made it into the piece for reasons of space, but at the height of WordSound they were doing pretty well, money-wise. He made a decent living from it. It's no secret that these days, like many indie operations, they're making much, much less money.
