The agility advantage: Navigating growth with a composable operating model

This article was written by Bloomberg’s Head of IBOR Product, Mark Ellis.

Investment managers are operating in an environment defined by constant, relentless change. Whether expanding into private markets, navigating evolving regulatory reporting requirements, or integrating AI-driven workflows into an investment process, success increasingly depends on the agility and scalability of a technology stack.

For years, the industry has gravitated toward the promise of the front-to-back solution – a single, fully integrated platform designed to offer a unified experience from trade idea to client reporting.

The appeal of such a model is clear: it promises operational efficiency, straight-through processing (STP), and a simplified vendor footprint with one vendor to call. However, as investment strategies grow more complex, many firms are discovering that a single, monolithic technology approach can sometimes lead to unexpected rigidity.

Empowering the front office: Tools, data, and decision velocity 

At the heart of every investment firm’s competitive edge is its investment team and their ability to make high-quality decisions at speed. Yet, a familiar tension consistently emerges from investment management clients: while firms want their teams focused squarely on core investment capabilities, operating models often limit flexibility in the front office, constraining access to the best tools and data when they matter most. 

In today’s markets, alpha is increasingly a function of decision velocity and insight. Investment professionals need timely, high-fidelity data, advanced analytics, and intuitive workflows that adapt to their strategies, not the other way around.  

At Bloomberg, technology enables a more flexible path forward. A composable operating model connects current infrastructure with future objectives, regardless of complexity. Powered by Bloomberg’s trusted data, this model allows a firm to replace, scale, and evolve a technology stack with confidence, staying perfectly aligned with a firm’s unique strategy at every stage.

Understanding the “front-to-back” landscape 

The front-to-back narrative is built on the pillars of efficiency and a single source of truth. While these goals remain essential, the practical implementation of a monolithic stack often presents several challenges that investment managers must navigate: 

The data schema reality: Even within integrated platforms, firms often manage multiple disparate schemas – such as the distinct data requirements for IBOR (Investment Book of Records) versus ABOR (Accounting Book of Records), or public versus private markets. 

The integration truth: No single vendor can provide 100% native technology across every domain; instead, most front-to-back solutions are a blend of native tools, acquisitions, and pass-through data. Furthermore, because these stacks often rely on third-party partnerships, they rarely represent a single, unified contract for the entire solution. 

The challenge of specialization: No single platform is best-in-class for every single tool; the depth of capability across risk, compliance, and portfolio management can vary significantly within one stack. The homogenization of value-creation workflows can stifle innovation. 

Time to value: Large-scale monolithic migrations can involve heavy configuration and lengthy data migrations, often impacting the speed at which a firm can respond to market changes.

Why the composable model is built for change

A composable approach isn’t just a different way to manage software; it is a modern operating model that prioritizes modularity and interoperability. It allows asset managers to choose a few key strategic technology partners into a flexible technology stack that grows alongside their business. 

Open architecture: Bloomberg Investment Management Solutions are API-first, designed to integrate seamlessly with proprietary models, internal systems and third-party providers.  

Agility and flexibility: Designed for change, the composable approach allows a firm to adapt individual components rapidly as your needs evolve. 

Scalability without overhaul: Functionally-driven scaling of components means a firm can optimize performance in specific areas without the downtime or cost associated with a full platform overhaul. 

Reduced operational risk: By diversifying the technology ecosystem, it can also mitigate dependency on a single provider and empower a firm to negotiate better terms and pricing.
