Atomos Adopts INDATA's Cloud SaaS, Signals Shift from Legacy Tech

GREENWICH, Conn. – March 17, 2026 – UK-based wealth manager Atomos Investments Limited has completed a significant technological overhaul, going live with INDATA's cloud-native Software-as-a-Service (SaaS) platform for its front, middle, and back-office operations. The move, which replaces the firm's previous investment management system, highlights a powerful industry trend: the accelerating migration away from aging, legacy infrastructure toward more agile, efficient, and intelligent solutions.

Atomos, an integrated wealth management company with headquarters in London and Bristol, manages a diverse range of client assets through model portfolios, multi-asset funds, and bespoke direct equity selections. The firm's decision to partner with INDATA underscores a strategic push to modernize its core operational framework and enhance its portfolio management and trading capabilities.

The Modernization Mandate

The financial services sector is grappling with the high cost of 'technical debt'—the implied cost of rework caused by choosing an easy, limited solution in the past instead of using a better approach that would have taken longer. For many wealth managers, this debt has manifested in a patchwork of disconnected, on-premise systems that hinder efficiency, introduce risk, and fail to provide the real-time data needed in today's fast-paced markets.

Atomos's search for a new provider was driven by precisely these challenges. The firm explicitly sought to eliminate its reliance on external spreadsheets for critical functions like model portfolio management and rebalancing. This common workaround, while once ubiquitous, is now seen as a major operational liability. Spreadsheets are notoriously prone to human error, lack robust audit trails, and cannot scale effectively as a firm's assets and complexity grow.

Furthermore, the company identified a need for superior cash management capabilities and a more automated reconciliation process with its custodian. These functions are foundational to operational integrity, and manual or semi-automated workflows can create significant bottlenecks, delay reporting, and increase the risk of costly errors. By targeting these specific pain points, Atomos's technology upgrade represents a textbook case of a modern wealth manager shedding legacy constraints to build a more resilient and scalable foundation.

From Spreadsheets to Smart SaaS

The tangible benefits of this transition were articulated by Joshua Gennet, Head of Investments for Atomos Investments Limited. "After implementing INDATA our portfolio management process is much more efficient," he commented. This efficiency gain is directly linked to moving complex workflows from manual, error-prone environments into a unified, automated system.

INDATA's platform provides a centralized solution for constructing, modeling, and rebalancing portfolios, removing the need for external tools and ensuring data consistency across the investment lifecycle. For a firm like Atomos, which manages both model-based and bespoke portfolios, this integrated capability is crucial for maintaining investment discipline and responding quickly to market changes.

Gennet also highlighted the immediate impact on core financial operations. "Being able to manage cash closely and efficiently is very important for us and INDATA's functionality in this area provides tangible benefits. Similarly, INDATA's recon process with our custodian is much better and more automated than our previous provider," he added. Automated reconciliation uses rules-based logic to match trades, cash flows, and positions between the firm's records and those of its custodian in near real-time. This not only dramatically reduces manual labor but also enhances accuracy, shortens closing cycles, and provides compliance teams with a clear, auditable record of all activity.

Cloud-Native Upstarts Challenge Legacy Giants

Atomos's selection of INDATA also shines a light on the shifting competitive dynamics within the financial technology landscape. For years, the market for Order and Portfolio Management Systems (OMS/PMS) was dominated by a few large, established players. However, many of these legacy systems were built on older architecture and have struggled to adapt to the new paradigm of cloud computing and artificial intelligence.

David Csiki, President of INDATA, noted this industry-wide shift. "In a changing industry where a number of traditional OMS/PMS providers are struggling to innovate because of legacy systems and ownership considerations, investment firms are looking to partner with next generation providers that offer newer approaches with greater efficiency," he stated.

INDATA positions itself as one of these next-generation providers, emphasizing its 'cloud-native' architecture. Unlike older systems that may have been retrofitted for the cloud, a cloud-native platform is built from the ground up to leverage the scalability, security, and agility of cloud infrastructure. This allows for continuous updates, remote accessibility, and a more seamless integration of advanced technologies.

Chief among these technologies is artificial intelligence. INDATA's suite includes iPM Portfolio Architect AI™, a tool that uses AI and machine learning to enhance portfolio construction, modeling, and reporting. By automating complex analytics and providing data-driven insights, such tools empower portfolio managers to make more informed decisions and free up their time to focus on high-value strategic activities.

This combination of a modern cloud architecture and embedded AI is proving to be a powerful draw for buyside firms seeking a competitive edge. It allows them to not only improve current operations but also to future-proof their technology stack, ensuring they can adapt to new market demands and regulatory requirements. The success of specialized providers in winning clients like Atomos signals that innovation and architectural purity are becoming key differentiators in a market once defined by incumbency. This strategic investment in a modern technology backbone is increasingly viewed as essential for any wealth manager aiming for sustained growth and operational excellence in the years ahead.
