We run this stack on our own capital.
ISF isn't a vendor guessing at what traders need. We built this infrastructure to run our own book — then hardened it until it was good enough to hand to other desks.
What we believe
Alpha is copyable in a weekend. Compliant, measured, reliable execution is not. So we don't sell strategies — we sell the rails: the order gateway, the replication engine, the sandbox, and the discipline that keeps them alive when a fill is late, a token dies, or the broker's API throws mid-close.
Every line on the money path is written to fail loud, not fail silent. A dropped order pages a human. A close subtracts what it actually sent, not what a stale position read claims. Nothing that can place, size or cancel an order ships without an independent review — because bugs found by running and bugs found by reading are different sets.
The record
Real Zerodha accounts, real capital, in production.
Each one guards an incident we don't intend to repeat.
A single monorepo, chaos-tested against partial fills and rejections.
