Private equity firm TPG Capital LP will buy Eze Castle Software and RealTick from ConvergEx Group for an undisclosed amount.

Eze Software develops investment-management technology, while RealTick is an asset-trading platform.

The combined company will be called Eze Software Group and will provide investment technology products. After the deal closes, Eze Software will buy Tradar, a portfolio-management and accounting-services software developer. 

TPG, based in Fort Worth, Texas, has more than $54.5 billion in assets under management. The firm’s portfolio companies include AgraQuest, BioCryst Pharmaceuticals and FleetPride.

The deal was announced on the heels of TPG’s backing of a consortium that agreed to buyout ShangPharma Corp. (NYSE: SHP) for $173 million in December
