Nominee accounts with per-investor truth
Track every investor's cash and holdings inside pooled nominee accounts: orders, settlement, dividends, and fees, all on one auditable record.
Pooled accounts, individual promises
Every investor's statement is a claim you must be able to prove.
Client money and assets pool in nominee and omnibus accounts at custodians and brokers, while each investor expects an exact position. Orders settle T+2, dividends fan out across thousands, and CASS-style audits ask for proof your database cannot give.
Client money pools at brokers and banks with per-investor attribution living in app code.
Order execution and T+2 settlement drift apart, and cash appears or vanishes for days.
Dividends, splits, and fees fan out across thousands of investors in batch scripts.
Client-money audits demand point-in-time segregation proofs that take weeks to build.
_PROOF/ Shares runs its investing infrastructure on Formance, attributing pooled positions per investor.
From order to settled holding
Cash reserved at order, holdings posted at settlement, attributed throughout.
An order reserves the investor's cash, execution converts it into a pending position, settlement posts the holding, and corporate actions fan out atomically, with the nominee account sub-ledgered per investor at every step.
The primitives investment platforms need
Built on the open-source Formance ledger.

Investing infrastructure, answered
01 / HOW IS CLIENT MONEY SEGREGATED?
Client cash lives in segregated account trees sub-ledgered per investor, reconciled continuously against the banks and brokers that hold it, provable for any date.
02 / WHAT HAPPENS BETWEEN EXECUTION AND SETTLEMENT?
Pending positions are explicit: cash is reserved at order, the position posts as pending at execution, and settlement converts it; nothing appears or vanishes.
03 / CAN FRACTIONAL SHARES BE TRACKED?
Yes: assets are ledgered with configurable precision, so fractional holdings carry the same double-entry guarantees as whole units.
04 / HOW DO YOU HANDLE MULTIPLE BROKERS AND CUSTODIANS?
Statements normalize into one schema and reconcile against ledger state continuously: one investor position across every venue, one audit trail.
