At Cirrus, we’re a small, bootstrapped team with a big mission — to simplify how retail traders manage multiple demat accounts across brokers. No more switching tabs or logging in and out of different platforms.

Just one interface, real-time execution, and serious infrastructure behind the scenes.But building this hasn't been easy.

Here’s a look into some of the toughest engineering challenges we’ve faced — and how we’ve solved them.

  • Multi-Broker Integration: Every broker API is different — inconsistent auth flows, rate limits, event formats, execution models. We built a dynamic adapter layer that abstracts these differences into a unified, real-time system.
  • ⚡ Real-Time Execution, No Visible Lag: From price feeds to trade updates, speed is non-negotiable. Our infra is built for real-time sync across accounts and devices — and we’ve spent months shaving off every millisecond of delay.
  • Multi-Account Order Execution: Handling trades across multiple accounts (all with different capital, risk setups, and brokers) meant building a smart execution engine. It syncs orders, scales positions using multipliers, and supports retries and rollbacks. And it all works live.
  • 🦀 Rust for Latency-Critical Paths: For performance-heavy components, we use Rust under the hood. It’s helped us achieve sharp latency and memory efficiency where traditional languages would fall short.

Still Day One: The platform is live, traders are onboard, and we’re battle-testing it every single day. As a bootstrapped team, we’ve put everything into building Cirrus — and we’re just getting started.
