Summary

Following a competitive RFP process, Brunel Pension Partnership entrusted AssetMetrix to deliver a comprehensive and future-ready operational solution. In just nine months, AssetMetrix completed one of its most ambitious and structured onboardings to date, achieving a successful go-live while meeting an accelerated timeline. This case study highlights how AssetMetrix combined speed, scale, and deep subject matter expertise to deliver immediate value across data migration, ESG reporting, GP communication, and platform enhancements. By transforming not only the data infrastructure but also the way data is interpreted, standardized, and utilized, AssetMetrix demonstrated its ability to act as a true extension of Brunel’s operational team. The result is a foundation for a long-term partnership, with an onboarding process that sets a new benchmark for excellence in the private capital industry.

AssetMetrix is proud to mark a major milestone in its collaboration with Brunel Pension Partnership: the successful completion of the go-live phase following a nine-month onboarding and migration journey. This achievement not only represents the operational readiness of the solution, but also underscores the strength, reliability, and adaptability of AssetMetrix’ offering, delivering tangible value from the very beginning.

The collaboration began following an extensive RFP process, culminating in the official signing of the agreement on October 9, 2024. From day one, both firms embarked on an ambitious and meticulously structured implementation journey. The onboarding was designed not just to transfer responsibilities, but to transform operational processes and create a future-proof setup that meets Brunel’s complex and evolving needs.

“Working with AssetMetrix is a game-changer for us. Their front and middle office solutions for private markets don't just streamline our operations - they've become an extension of our team. It's a true partnership - built on trust, innovation, and a shared commitment to excellence.”

— Melissa Freudenstein, Head of Operations Brunel Pension Partnership

Structured for Success: A Five-Phase Approach

To ensure a seamless transition and high-quality delivery, the implementation was divided into five well-defined phases:

1. Initiation and Initial Setup

This phase focused on aligning expectations, defining clear deliverables, setting up governance structures, and identifying all necessary data sources. Key milestones included the approval of a project charter and alignment of timelines, responsibilities, and stakeholder engagement.

2. Operational Solution Setup

In this stage, AssetMetrix delivered a fully functional platform, including:

  • Comprehensive data and document migration

  • ESG data campaign setup

  • Client-specific training for both operational and strategic stakeholders

Alongside the framework and structure for the pre-agreed day-two deliverables.

3. Operational Handover Readiness

Before ownership of processes could be transferred, a detailed readiness assessment was conducted to ensure systems, people, and procedures were fully prepared. This included trial data runs, reconciliation testing, and validation of workflows.

4. Operational Handover

This critical stage marks the transfer of responsibilities from Brunel’s outgoing provider which previously provided Brunel these services to AssetMetrix. As of today, AssetMetrix is the responsible party for most operations, with some remaining to be handed over. Following the formal Go/No-Go checkpoint, the team has initiated the live operation of all the initial services, with the rest due to be live before the end of the year.

5. Final Acceptance Process

Final quality assurance checks will be conducted to validate the integrity of the data, completeness of the migration, and operational reliability of the solution. This milestone will serve as the formal conclusion of the onboarding process and a handoff into business-as-usual operations.

Taking Ownership: A Deep Dive into Value Delivery

From data to documentation, every aspect of the onboarding was handled with a focus on precision, scalability, and long-term benefit. AssetMetrix’ goal was not just to replicate Brunel’s previous setup, but to elevate it.

General Partner Onboarding

A cornerstone of AssetMetrix’s value proposition is its proactive, direct engagement with General Partners (GPs) on behalf of Limited Partners (LPs). For Brunel, AssetMetrix took ownership of communication with 97 direct GPs and 62 Fund-of-Fund managers, responsible for data collection across performance, ESG, valuations, and more. This removed a major operational burden from Brunel and allowed for streamlined, accurate, and timely data flows into the AssetMetrix platform.

Document Management

Document migration was a critical element of the onboarding. AssetMetrix successfully migrated over 30,000 documents from Brunel’s previous provider. This process included:

  • Mapping all legacy documents to a newly designed, more comprehensive taxonomy

  • Assigning detailed metadata for each file, including fund, investor, and document type associations

  • Using automation scripts to ingest documents into a centralized, secure document lake

  • Enabling advanced retrieval options through filters and full-text search

The result is a single source of truth for all documents, accessible and searchable within seconds.

Data Migration and Transformation

“Data migration is one of the most critical and complex phases during client onboarding. It’s not just about transferring data, it’s about ensuring that master data, transactional records, and investment structures are accurately mapped to the new environment while preserving data integrity, traceability, and regulatory compliance.”

— Jiaojiao Zhao, FRM - Senior Solutions Engineer Data

For Brunel, the data migration phase presented both a strategic opportunity and a technical challenge. The task involved ingesting, mapping, and transforming vast amounts of sensitive and interconnected data. With a portfolio comprising 10 sub-portfolios across 4 investment cycles, over 700 fund investor accounts, more than 3,000 underlying private capital objects (PCOs), and over 120,000 transactions, the data landscape was both extensive and nuanced.

Key challenges addressed during this phase included:

  • Investment Structure Alignment: Complex multi-level hierarchies, especially from fund-of-fund (FoF) structures, were redesigned for consistency and to support new analytics and reporting logic.

  • Master Data Standardization: Inconsistent taxonomies, entity naming mismatches, and missing attributes across data sources required intensive consolidation and cleansing to ensure uniformity and downstream usability.

  • Transactional Data Mapping: Historical transaction records had to be deeply analyzed and mapped to ensure accuracy in performance measurement and reporting. Several cases required the creation of custom rules or new logic to handle non-standard scenarios.

  • Data Transformation Complexity: A delta migration strategy was employed to integrate live in-flight changes during the transition window. This added another layer of complexity, as changes needed to be accurately synchronized without disruption.

  • Comprehensive Data Inventory: Over 800 unique data points were catalogued to map external records to internal structures. This inventory ensured full traceability and minimized the risk of data gaps or logic misalignment.

  • Enhancements Beyond Legacy Providers: Some areas of Brunel’s portfolio required new and improved handling, such as cycle breakdowns, recapitalized distributions, unit-based tracking, or portal-ready data logic—surpassing what their previous provider was able to offer.

  • Case-by-Case Investment Handling: Specific investments called for tailored treatments, including advanced data aggregation or segregation, to reflect Brunel’s internal investment logic.

  • Reconciliation and Validation: Post-migration, a rigorous reconciliation process was carried out to match balances, valuations, and mappings against expected outcomes. Discrepancies were flagged, analyzed, and corrected with close client involvement.

  • Transition to BAU: Final preparations for the business-as-usual phase included historical data corrections and adjustment bookings. Complex legacy data gaps were addressed through official documentation, and all processes were handed over cleanly to operational teams.

This phase not only ensured data integrity and operational continuity for Brunel but also drove significant learnings and enhancements within the AssetMetrix platform—raising the bar for all future migrations and client onboardings.

ESG Data Campaigns

ESG reporting is a key focus area for Brunel, and AssetMetrix delivered a tailored, multi-stream data collection strategy. To date, four of five ESG campaigns have been completed, with the final campaign for Private Equity currently underway.

The approach has been flexible by design:

  • Templates and workflows for Fund-of-Funds across select asset classes

  • Direct engagement support Brunel’s strategic partner for Private Equity ESG data

  • Manual outreach where faster results could be achieved

  • Bulk data ingestion for Infrastructure portfolio

This flexibility illustrates the AssetMetrix capability to tailor ESG solutions based on a client’s unique needs, supporting both standardised reporting frameworks and bespoke requirements.

Workflow Engine Enhancements

In the spirit of continuous improvement, the onboarding led to major product enhancements within the AssetMetrix workflow engine. The transactional export logic was revamped to include:

  • Additional bank account data fields

  • Safety checks and validation rules

  • Enhanced approval steps and routing logic

These developments were designed with Brunel in mind but are now part of the core platform, benefiting all clients going forward.

People Behind the Process

Behind every successful onboarding lies a team of committed professionals. Over 30 AssetMetrix team members across Implementation, Client Service, Data Services, Fund Services, ESG, Legal, Product and IT contributed to the success of this onboarding with months of a quasi-parallel run, totaling over 6000 hours of effort.

“This onboarding project showcased the power of structured project management, clear communication, and a unified commitment across organizations. With significant requirements and a tightly scoped delivery timeline, we worked with precision and agility to meet an ambitious go-live target. By leveraging the full spectrum of AssetMetrix products and solutions and aligning cross-functional teams across organizations early on, we maintained the project timeline while ensuring quality and compliance. Most importantly, we focused on building trust from day one, laying the foundation for a long-term partnership. The collaboration, transparency, and shared accountability were key to the project's successful acceptance.”

— David Dumenigo – Co-Head of Customer Success

Their deep experience, collaborative approach, and problem-solving mindset ensured that challenges were not only met but turned into opportunities for innovation.

Laying the Foundation for the Future

The onboarding of Brunel Pension Partnership represents one the most structured and complex implementation delivered by AssetMetrix in recent years, reenforcing our ability to onboard large managers in tight timelines. The scale, ambition, and thoroughness of the process have laid a rock-solid foundation for a long-term, strategic partnership.

What makes this success especially meaningful is the dual value it has delivered: for Brunel, a solution tailored exactly to their needs; for AssetMetrix, a new level of operational maturity and product evolution that will benefit all clients across the platform.

The journey with Brunel has just begun, but its early achievements have already demonstrated what AssetMetrix does best, transforming complexity into clarity, and partnerships into progress.
