Multi-venue books live in fragmented spreadsheets

CIOs discover true exposure days late. Rebalancing is manual CSV gymnastics. Investor reports do not tie to broker statements.

  • ×FX, crypto, and equities in siloed dashboards.
  • ×Cash idle in one venue while margin stressed elsewhere.
  • ×No strategy-level attribution across shared accounts.
  • ×Month-end reconciliation burns analyst weeks.

Unified portfolio management software

Automated ingest from APIs, normalized position model, P&L engines with FX conversion, and rebalancing tickets with approval flows.

  • Single book view updated intraday.
  • Strategy and sleeve attribution with configurable hierarchy.
  • Rebalance proposals with pre-trade compliance checks.
  • Investor PDF packs generated from same ledger as ops.
