The platform we wouldwant to run ourselves.
Propper is a white-label platform for prop firms, built by a small team that trades. Not a white-label of somebody else and not a bought-in engine: we write it ourselves, every day.
The decisions under every screen.
- 01
We are the broker
Execution, fills and P&L run on our own engine. No third party in the middle decides what a trader's fill was.
- 02
Risk before execution
A trade that breaks a rule is refused, not reversed afterwards. That is a choice in the architecture, and it is why your rules hold.
- 03
Firms kept apart in the database
Row level security in the database itself keeps every firm apart, so one firm cannot read another's rows even if the application asked it to.
- 04
Real time throughout
Prices, positions, risk alerts, news and ticket messages arrive over WebSockets. Nothing waits for a refresh.
- 05
Built in the open
A public roadmap of what comes next, a status page for every firm, and the platform counted in our own repository with every change.
Built by traders,
for traders.
We don't just build trading software, we use it. Every feature is shaped by real trading experience. Every firm gets its own account manager at Propper: one person you reach directly, for every question.
Runs the company: the finances, the big decisions and where Propper goes next. Also builds the whole platform, end to end.
Leads marketing and new business, and keeps the daily operations on track so every firm that comes on board is looked after.
Checks everything before it goes out, keeps the two of us in line and helps out in customer support. Not on the payroll.
One platform,
built in the open.
No white-label of someone else, no bought-in engine. We write this ourselves, every day. These numbers are counted in our own repository with every change we make.
Your name on the door.
Our engine behind it.
