About · Stwlth Software
Hidden valuebuilds advantage.
Stwlth Software is a founder-led studio in Illinois. We build websites, software and brands, and run the media systems behind them, for companies that want practical technology, not complexity for its own sake.
STWLTH is pronounced “stealth.”
The spelling hides a second word. The W replaces the EA in stealth, so wealth sits inside the name, in plain sight. The mark does the same: three planes that read as a W only once you look.
That's the job we think technology should do: create value quietly, in the background. Sometimes that value is revenue. More often it's hours handed back to a team, a manual process that no longer exists, or software that lets a business do something it couldn't do before.
Founder-led. Engineering-first.
Marcus Lee
Marcus is a senior full-stack engineer who designs, builds, and runs software end to end. He built Stwlth Wealth (22 financial simulators with accounts, an AI assistant, and an installable app that works offline) and the transcription and video pipelines the studio runs on its own hardware.
He started Stwlth Software for the work people still do by hand: the invoice retyped into accounting, the Friday report rebuilt from exports, the hour of footage captioned line by line. Software should do those jobs every time, without anyone having to think about them.

Two or three sentences is plenty: the launch, the system, the thing still done by hand. You'll hear back from the founder, not a sequence.
