NowHouse

The interesting thing about NowHouse is what it refuses to depend on. Most brokerage post-trade stacks inherit their truth from the custodian: the books look right once the daily snapshot file lands, and everything before that is an estimate. NowHouse inverts that by giving you your own ledger as the source of truth — double-entry, immutable backups, and every share accounted for — and then reconciling against the custodian rather than the other way round. The vendor is explicit that this reduces reconciliation work without requiring self-clearing status, which is the honest framing: you get much of the operational benefit of self-clearing without the capital, licensing and operational burden. The schema flexibility is the part that will decide whether it fits you. You can define asset classes, build transaction templates, and spin up separate ledgers for IRAs, equities, or an emerging markets strategy — as many ledgers as you need. For a multi-strategy firm this matters more than raw speed, because it means one system can hold books that a single custodian account structure would force you to blend. On top of that, holdings are derived from a single transaction history, so buying power, selling power and withdrawable cash are computed rather than hand-maintained, and traders can pull intraday charts going as far back as they need. Funding visibility is the other half. Deposits, ACATS transfers, checks to your custodian and custodian corporate actions are all tracked as they land, so your operations team sees trade or funding progress in real time instead of reconstructing it later. The infrastructure claims are modest and specific: multi-region cloud hosting, high throughput and low latency reads and writes, immutable backups, audit-ready records. Where NowHouse is genuinely constrained is scope. It is not a trading platform, not a market data product, and not something an individual retail trader can buy. It is enterprise post-trade infrastructure sold to brokerages, and the value case is strongest for firms whose volume makes manual reconciliation expensive. A firm doing very little trade volume will find the migration and onboarding effort outweighs the benefit. There is also real concentration risk in adopting any vendor that becomes your books of record — you are trusting one company's ledger to be the truth your auditors see, so the audit-ready and immutable-backup promises deserve scrutiny in diligence rather than acceptance on the marketing page. Treat NowHouse as infrastructure: evaluate it the way you would evaluate a core system, not the way you would evaluate a tool.
