I interviewed with these guys about 9 months or so ago in the NYC office and at the time there was only one guy there but he was trading pretty big (mainly spreading between the cash and futures in the Treasury market). Bob, I think is his name, who was running the office told me that a bunch of his traders left for Refco mainly because they offered a better deal. From what I remember, the standard deal that Transmarket offered was something like after 200k or 500k (don't remember which) you make for Transmarket, you get a 50/50 split after that amount. Needless to say, a pretty bad deal, Bob even told me that if I was looking for the best deal, to go to Refco. Again, this was 9 months ago, so things might have changed a lot since then.
