Quantium NAV Oversight turns administrator data into one verified set of fund and investor numbers that Finance can use and sign off. It works however the data arrives: Excel, PDF, API or your data warehouse.

The problem
Having the data is not the same as having the numbers.
The data may already be in Excel packs, an API feed or a data warehouse. Finance still cannot work with it directly. NAV, IRR, fees and carry get rebuilt in spreadsheets, and the same figure ends up in three versions. Nobody has verified the numbers before they are used.
Your administrator's fund-level numbers are reliable, and you have no reason to replicate them. What is missing is the structure around them: how funds, feeders, parallel vehicles, co-investments and investor groups fit together. Without it, every cross-fund total, interim IRR or LP question becomes another spreadsheet.
SourceAdministrator fund-level data
QuantiumAdd the structure
OutputCross-fund views, interim IRR, LP reports
What Quantium does
Adds that structure on top of the administrator's figures, linking funds, feeders, parallel vehicles, co-investments and investor groups in one model. Cross-fund totals, interim NAV and IRR, and LP reports then come straight from it.
Finance answers from one set of numbers, without rebuilding them.
02Use case
Check the numbers before you approve them
Several administrators, each with its own templates, account names and investor IDs. Before NAV, fees or capital accounts go to LPs, Finance wants to check them against source.
SourcePacks from each administrator
QuantiumCheck and sign off
OutputApproved figures to reports and AI
What Quantium does
Brings every administrator's pack and GL into one data model and checks NAV, fees and capital accounts against source. You set how deep each check goes, from the headline figures to every investor line. Finance's sign-off is recorded by fund and period.
Only figures Finance has approved reach LP reports.

Expertise
An accounting engine, not a dashboard.
A dashboard shows the numbers it is given. Quantium understands how your funds, vehicles and investors fit together, down to each LP's share. So it can calculate fees, IRR and carry from the underlying data, and check them against what your administrator reported.
01
Accounting-grade calculations
Investor allocations, IRR, fees, carry and waterfalls are calculated on the same engine that runs full fund accounting for Quantium clients. Not in spreadsheets, and not by a language model.
02
Understands your structure
Feeders, parallel funds, co-investments, SPVs, blockers and investor groups, and each LP's share of them, across administrators and currencies.
03
Cross-checks, not just charts
Fees from LPA terms, IRR from dated cash flows, capital accounts from each LP's share. Each can be checked against the administrator's figures.
Talk through your setup with our team.
Your structure, your administrators, your reporting cycle. We will show where NAV Oversight fits and what it takes to get there.
Every administrator reports differently: different templates, account names, investor IDs and reporting dates. Quantium brings them into one fund and investor data model and verifies the numbers. A capital account from one administrator can then be relied on as much as one from another.
Differences on record
When a figure does not match the administrator's, it is flagged, then resolved or noted with a reason before anything is published.

NAV Oversight & Reconciliation
Buyer questions
What is NAV Oversight?
NAV Oversight is fund data management software for private markets managers that use one or more fund administrators. Quantium takes each administrator's NAV packs, capital account statements and GL extracts, maps them into one fund and investor data model, checks key figures against source and records Finance's sign-off. Teams then report, analyze and share from one verified set of numbers.
Do we need a data warehouse?
No. Quantium works directly from administrator packs, Excel files and GLs, or alongside a warehouse you already run. If you have one, verified figures can flow back into it.
What formats can administrators send?
Administrators can send Excel workbooks, PDF statements, GL extracts, API feeds or data warehouse tables. Each administrator's layout is mapped once during implementation, and later periods follow the same mapping.
Do we have to give up Excel?
No. Excel stays useful for analysis and presentation. What changes is that the numbers no longer start in a spreadsheet: any figure can be exported with its formulas and source links.
Who signs off?
Your finance team. Quantium records what was checked, what was flagged and who approved each fund and period.
Does it replace our administrator or our BI tools?
No. Your administrator keeps preparing the official books, and your dashboards keep working. Quantium adds the control and calculation layer between them.
