Our view of the market

“Financial services are at a turning point. For the first time, fintechs are gaining market share, not just innovating. Banks and fintechs now face complex regulations that sometimes call their business models into question.

In this context, technology is a key differentiator. APIs and event-driven architectures pave the way for more fluid, real-time finance. Agentic systems—the most advanced form of generative AI—will enable proactive service for users and teams. Trusted, distributed data will empower smarter, business-driven decisions.”
