Co-Sourcing with Alter Domus: A Custom Approach for General Partners

Alter Domus understands that every General Partner has unique operational needs, which is why we offer tailored co-sourcing strategies to enhance efficiency and maintain control. Our expertise allows clients to focus on strategic growth while we manage execution and ensure regulatory compliance.


People shaking hands

In the dynamic landscape of private markets, every General Partner (GP) has unique operational needs and preferences. At Alter Domus, we understand that a one-size-fits-all model simply doesn’t work. Instead, we adopt a consultative approach, collaborating with each client to define a co-sourcing strategy that aligns with their specific requirements.

Whether it’s supporting a single process like Annex IV reporting or managing full fund accounting cycles within the client’s infrastructure, our flexibility ensures that we meet diverse operational contexts. 

Here are some examples of how we empower GPs through customized services and expertise: 

Typical Capabilities Include:

  • Fund Accounting: We prepare books and records using the client’s technology platform, with workflows designed for dual review and sign-off.
  • Capital Activity: We calculate and format capital calls, distributions, and notices, while clients retain approval rights and manage LP communications.
  • Regulatory Reporting: Our teams collect, map, and format data to comply with evolving local and cross-border obligations.

By partnering with us, internal GP teams can concentrate on oversight and strategy, while our dedicated professionals manage execution within a clearly defined control framework. 

Making the Shift: Practical Considerations:

Transitioning to a co-sourcing model doesn’t mean overhauling existing systems or starting from scratch. With years of implementation experience, we guide clients through a structured transition focused on clarity, integration, and flexibility. 

Through our extensive work with clients, we’ve identified three key building blocks essential for unlocking the full potential of a co-sourced operating model: 

1. Define the right scope: We pinpoint operational areas under pressure, such as:

  • Fund closings and reconciliations
  • Capital statements and investor notices
  • Data preparation for regulatory reporting
  • Waterfall modeling and fee recalculations

2. Maintain System Continuity: Clients keep their platforms while we securely integrate into their ecosystem, ensuring a single source of truth and avoiding fragmentation.

3. Establish Strong Governance: We align with each client’s compliance and oversight model, ensuring clear roles, documentation, and audit trails. Managers retain ultimate responsibility, while our teams execute defined workflows according to agreed service-level agreements (SLAs).
