Custom software development, built and run in Chicago.
10 US Tech is a software engineering firm in Chicago, built around a small senior team. We design, build, and hand over web, mobile, cloud, AI, and point-of-sale systems — and we run our own software in production in Chicago. Fixed scope. Fixed price. You own everything on handoff.
We don’t just ship software. We run it.
Most agencies build you a system and disappear. We build software, put our own name behind it, and keep it running in production — on the same streets we work from. That means when we tell you something scales, holds up under load, or survives a Friday-night rush, it’s because ours already does.

The digital handoff — you own everything.
- You own it all on handoff. Code, repositories, cloud accounts, and domains transfer to you. No lock-in, no hostage infrastructure.
- Fixed scope, fixed price. Agreed before we start. No hourly meter, no surprise invoices, no published rate card to game.
- Honest about certifications. We are not SOC 2, HIPAA, or ISO certified, and we say so plainly. For regulated work we architect to the specific control, document it, and bring in certified partners where a certification is legally required — rather than claiming a badge we don’t hold.
- One senior team. The people who scope your project are the people who build it and hand it over.
