Eamonn O'Kane and Marc McCullough walked away from the Craigavon Leisure Centre brimming with confidence after two eye-catching victories on Saturday night.
Commonwealth Games middleweight gold medallist O'Kane was always a class above Tommy Tolan in their six-rounder and the Belfast man failed to come out for the final round.
It's two out of two for O'Kane who now expects to return to action on July 23 in London.
O'Kane said: "I'm very pleased with my performance, Tommy made it tough, particularly inside where he was holding. It was a good learning fight for me and a great start to my pro career."
Featherweight McCullough won the battle of the debutants when he stopped fellow Belfast man Eddie Nesbitt in the second round, having floored him in the first.
Lurgan welterweight Stephen Haughian easily outpointed Poland's Arek Malek over six rounds, while unbeaten flyweight Jamie Conlan was taken the distance by journeyman Delroy Spencer in their six-rounder.
Omagh's Dee Taggart and Belfast's Mark Ginley also won on points against Scotland's Guiseppe Daprato and England's Robin Deakin respectively, while in Dublin Belfast's Ciaran Healy pulled off a shock with a first round knockout of Brendan Fitzpatrick - his first pro loss.
In Cologne, Irishman Matthew Macklin felt he was robbed of the WBA World middleweight title when he lost a split decision to German Felix Sturm, 116-112, 116-112, 113-115. Macklin is hoping for an immediate re-match.
