Sigma Computing Consulting for Family Offices
Stop rebuilding the consolidated net worth report from custodian statements every month. We build Sigma workbooks on Snowflake that bring every account and private investment into one view.
The short answer
Where the Hours Go Today
- The consolidated report is built by hand from custodian and bank statements.
- Private fund values and capital calls are tracked in a separate spreadsheet.
- Every entity, trust and family member needs a slightly different version.
- Questions about past allocations mean digging up old files.
Sigma Workbooks We Build
- Consolidated Holdings
- Positions and values across every custodian, bank and private investment by entity, account and asset class, stored by date.
- Private Investments and Capital Calls
- Commitments, calls, distributions and latest values for each fund and direct deal, with upcoming calls next to available cash.
- Performance and Allocation
- Returns and allocation against targets by entity and asset class over any date range.
- Family and Entity Reporting
- Scheduled reports for each family member or entity, each limited to the accounts they own.
Why Sigma Fits
- Each person sees only their accounts
- Row-level security by user, team or user attribute lets one workbook serve every family member and entity.
- Manual values stored properly
- Input tables let staff enter private fund marks, notes and targets that are stored in the warehouse next to custodian data.
- A familiar grid
- Staff work in a spreadsheet interface on live warehouse data instead of copying statements into Excel.
Data We Connect
- Custodian and bank feeds
- Private fund statements
- Direct investment records
- Accounting system
- Entity and ownership records
- Excel trackers
- Snowflake
Common questions
Is Sigma good for family office reporting?
Sigma fits family offices with several custodians, entities and private investments whose staff work in spreadsheets and want one warehouse behind the reports.
Can Sigma consolidate several custodians?
Yes, once custodian feeds or statements are loaded into Snowflake and mapped to one list of accounts and securities. Sigma then reports across all of them.
Can we track capital calls and private fund values?
Yes. Commitments, calls and distributions are loaded or entered in input tables, and the latest marks sit next to custodian holdings in the same report.
Can each family member see only their own accounts?
Yes. Row-level security limits each user to their own entities and accounts, while the office sees everything in the same workbook.
How long does a Sigma build take?
It depends on how many custodians, entities and private investments you have. We scope it on a short call, starting with one report.
