Argent Software

Custom trading platforms aren’t common in the financial district. Argent Software specializes in them, writing code that handles market data feeds, order routing, and risk checks without the bloat of off-the-shelf packages. Wall Street firms that need low-latency execution or bespoke analytics often turn to local shops instead of distant vendors.

The company occupies a floor at 100 Wall St, New York, NY 10005, where the elevator banks still smell of polished brass and the hum of servers competes with the harbor wind. Software engineers here build everything from FIX engines to real-time P&L dashboards, keeping the tooling lean enough for a single trader yet scalable for an institutional desk. Clients typically arrive with a napkin sketch and leave with a binary that speaks their broker’s dialect.

Most projects start with a call to (646) 763-8400; the line rings through to a developer, not a sales script. After a quick screen share, the team quotes a fixed-price sprint or a retainer, depending on how much the spec wiggles. Documentation is sparse—comments live in the code, not in three-ring binders—so new hires spend their first week tracing function calls instead of reading manuals.

For directions, pull up the map and look for the building with the copper spire. If the receptionist isn’t at the desk, just follow the keyboard clatter to the open-plan bullpen. Everyone here still thinks in C++.
