# Custom software development in Chicago. We build it and we run it.

10 US Tech is a small software engineering firm in Chicago with a senior team. We design and build web, mobile, cloud, AI and point-of-sale systems. Our own software runs in production here in Chicago. **Scope and price are agreed before we start.** At launch you can take the code, accounts and domain outright, or we run it for you on a monthly retainer.

## Software we run ourselves

A lot of agencies build a system and move on. We keep ours running in production, in the same city we work from. So when we say something holds up on a busy Friday night, it’s because our own software has had to.

### Quantum Prosthetics & Orthotics

A clinical group with six clinics in three states (Illinois, Indiana, Nevada). We built its website and we manage it. Patients use it to find a clinic, so it has to stay up.

## The digital handoff

- **Yours at launch, or ours to run.** At launch you can take the code, accounts and domain outright, or we run it for you on a monthly retainer. Nothing is held back to keep you tied to us.

- **Fixed scope, fixed price.** Agreed before we start. We don’t bill by the hour and we don’t publish a rate card.

- **Honest about certifications.** We hold **no** compliance certification (SOC 2, HIPAA, ISO), and we say so plainly. For regulated work we design to the specific control and document it. Where the law requires a certification, we bring in a certified partner.

- **One senior team.** The people who scope your project are the people who build it and hand it over.

## Common questions

**Is 10 US Tech actually based in Chicago?**

Yes. 10 US Tech Inc. is a Chicago-based software engineering firm, and our own software runs in production in Chicago.

**Do you work with clients outside Chicago?**

Yes. Our clinic client Quantum Prosthetics & Orthotics has clinics in Illinois, Indiana, and Nevada, and we built and manage its website. Chicago is our home base, not our limit.

**Do you charge by the hour?**

No. We work in fixed scope at a fixed price, agreed before we start. There is no hourly meter and no surprise invoices.

**Do we own the code you build?**

Yes. At launch you can take the code, accounts and domain outright, or we run it for you on a monthly retainer. We call it the digital handoff.

**Are you SOC 2, HIPAA, or ISO certified?**

No, 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 do not hold.
