TradeSync is the trade-lifecycle platform for funds, prop desks, and brokers who are done writing Python glue at 11pm. One ledger, one audit trail, sub-millisecond reconciliation.
Order hits the gateway. Symbol resolved, book assigned, risk pre-check runs in under 80µs. No queueing, no batch — every order gets an ID and an audit row before it leaves the network card.
Built with engineers who worked at funds and broker-dealers. Every API, webhook, and UI is something someone burned an evening trying to hand-roll — and now never has to again.
Position, exposure, margin, concentration — evaluated against live book in single-digit µs.
Your trades ⇄ exec broker ⇄ prime broker, continuously matched. Breaks raised before coffee.
Append-only, cryptographically chained. Every state reachable, every change explainable to audit.
Python, TypeScript, Go. Idempotent by contract. Webhook retries with signed payloads.

Usage-based with a hard ceiling. No "contact sales" on the middle tier. We'd rather you leave fast than churn slow.
Solo desks and research teams.
Prop, market-making, middle-market funds.
Broker-dealers and large funds.
Fourteen days. No credit card. Your keys in ten minutes. If we don't replace at least two of your cron jobs by day three, we'll tell you.
