Arcesium

Arcesium builds financial data management and post trade infrastructure for investment managers, organised around three named products rather than one monolithic suite.

Opterra handles operations, connecting activities, standardising execution and surfacing insights. Its coverage is concrete: regulatory reporting for filing and data sharing obligations, unified accounting through a universal book of record, automated allocations at both performance and investor level, reconciliations from any counterparty, administrator, client or third party system, treasury management for yield opportunities, and data harmonisation across large volumes.

Reconciliation from any source is the least glamorous item and the most valuable. A fund receives data in whatever format each counterparty happens to send, and the work of making those agree is where operations teams actually spend their days.

Limina, now integrated, delivers a cloud native front to back investment platform with multi asset portfolio and order management, joining front, middle and back office in one architecture so teams share a consistent real time view of positions, cash, exposures and performance rather than reconciling fragmented systems. Aquata is the data and analytics platform underneath. Arcesium maintains a pricing page but publishes no figures on it.
