Subscribe to our newsletter

Broker-dealers, investment banks and market makers are having to navigate mounting pressure from multi-asset fragmentation, compressed margins and increasingly stringent regulatory demands such as MiFID II and T+1 settlement cycles.

Rather than executing sweeping, high-risk lift-and-shift overhauls, financial institutions are focusing on practical evolution: modernising data supply chains, unifying siloed front-to-back systems and replacing brittle legacy infrastructure with cloud-native architectures.

The following profiles evaluate 12 technology vendors providing solutions to these challenges, helping institutional firms modernise their data architectures and optimise daily trading operations for Chief Data Officers, Heads of Sell-Side Technology and Heads of Operations.
