4Pines and Entrilia: The Technology Partnership Defining Co-sourcing

For private capital CFOs, the operational “tax” has always been the same: choose what you value most, because you can’t have both.

Choose control with an in-house team, and you absorb the cost, the manual lift, and the spreadsheet exposure.
Choose convenience with outsourcing, and you surrender transparency, speed, and access to your own data.

Many assumed this tradeoff was simply the cost of doing business, when it really was the cost of legacy technology.

Now there’s a different path.

The Strategic Shift Toward Co-sourcing

Co-sourcing has become the modern operating standard for private capital firms. In this model, your fund administrator works directly inside your GP-owned software environment, instead of some separate system you can’t see or control.

That means:

Data ownership stays with you. Your data never leaves your environment: you maintain control, transparency, and auditability at all times.
One system & dataset. The GP and administrator operate from the same records, which means no parallel systems, no reconciling, no off-system Excel files.
Higher-value administration. Your administrator can move beyond manual processing and focus on relevant insights, all due to modern automation and shared workflows.

Co-sourcing replaces the old either/or: you can have in-house control while also gaining the efficiency and expertise of an external administrator without the usual sacrifices.

4Pines + Entrilia: Returning Operational Control to the GP

As private capital firms grow, they quickly discover that traditional administration models don’t grow with them. Quite the opposite: systems unexpectedly break, Excel fills all the gaps, and reporting inevitably slows down.

4Pines Fund Services, founded by former CFOs who’d seen this pattern countless times, designed their model to scale without breaking. Their starting point was clear: Give the GP ownership of the system, the data, and the workflows.

To pull that off, they needed technology that was:

Flexible
API-driven
Automation-focused
Purpose-built for private capital

Entrilia checked every box required to make this model work.

4Pines says our platform is “well-suited to their style and high-performance mindset” and “allows them to say yes more often and with greater conviction.”

Today, work that used to happen “off-system”—management fees, capital calls, allocations, reporting packages—now runs directly on Entrilia. Clients immediately felt the difference, describing it as “having an in-house team without the overhead.”

For investors, that translates into faster closes, cleaner audits, and more reliable data. For GPs, it means the back office stops being a constraint, and becomes an advantage.

Why Co-sourcing Is Replacing the Legacy Admin Model

Our partners at 4Pines say it plainly: legacy fund administration “was not designed through the CFO lens.”

And it shows — the old model depends on handoffs and black-box processes at a time when firms are dealing with tighter deadlines, more complex structures, and LPs who want answers immediately.

With co-sourcing, the GP owns the system that the administrator works in. It results in a partnership that’s quicker, clearer, and “more agile, transparent, and resilient,” as 4Pines describes it.

Entrilia: The Technology Behind Co-sourcing

Co-sourcing only works when the platform can actually support shared ownership and execution. Entrilia was built for exactly that.

We provide:

A unified dataset that keeps information consistent
Automated processes that replace manual Excel work
A shared, secure environment for flawless GP/Admin collaboration
An open and flexible architecture that adapts to your firm's processes

This openness is what unlocks the deeper integration. Entrilia’s APIs let 4Pines pull Investor ID lookups, audit logs, and reports straight into their agnostic C2P platform, so everything appears directly in the workflow their team already uses.

It also gives real control: our Key/API framework lets the team specify exactly what each client can access, while still relying on Entrilia’s report designers for the underlying logic. C2P stays fully configurable on top, with Entrilia powering the accuracy underneath.

“The integrations we can do with Entrilia into our C2P platform are way above what we can do with other platforms. Having Entrilia data lookups and reporting directly in our application is game changing.”

Administrators like 4Pines deliver a high-efficiency and high-transparency service, and GPs can finally reclaim ownership, ending the toxic tradeoff between control and convenience.
