Custom systems wired into how the business already runs. Not a template shop, not a marketing agency, not a product demo. We map the work, build the system to fit it, and ship it.

How is a project priced?

Scoped individually and priced up front. No packages stuffed with things you will never use. No surprise invoices. The first conversation is free.

How long does it take?

Live in 7 to 14 days. We scope the timeline up front so you know it before we start.

Ethan. You start a project with the person who builds the system. He follows up within 24 hours. If we are not the right fit, we will say so.

Who keeps the accounts and the data?

You do. You keep the accounts, the data, and control from day one.

No. No long-term contracts. If you want to walk away, the accounts, the data, and control go with you.

What happens after I send the form?

Ethan replies within 24 hours. You get a scoped quote. Then the build. After ship, a support window is included. The Care Plan is optional monthly support if you want a longer line.

How it works

Clay miniature of Duke, a faceless figure in a long black coat, walking along a three-stage conveyor on a cream tabletop: a scoop of raw gray clay, a press molding it into shape, and a finished package lifted off a gold cloth.

The work

Where the system gets wired in

Four jobs we take on. Each one molded to how the business already runs.

The work that repeats

The same task, week after week. We wire a system into how that work already runs so it stops eating the calendar.

The handoff that drops

Notes, files, and follow-ups that die between people. A system that carries the work the way the shop already hands it off.

The tool only one person can run

The spreadsheet or inbox that lives in one head. Shaped to how they already work, so the shop does not stall when they are out.

The report that takes a week

Numbers pulled by hand from three places. Wired into the sources you already use, so the report is ready when you need it.

What this is not

One offer. Not a catalog.

AI molded to your business. Custom systems wired into how it already runs. That is the whole shop.

Duke stands at a fork in a cobblestone path. One branch is buried in tangled cables and app icons, the other is a single clean gold rail leading toward a yellow Pittsburgh bridge.

Not a template shop

If you need a website, it is built around how your business runs.

Not a marketing agency

We do not run ads, brand campaigns, or content calendars. The work is the system your team uses day to day.

Not a product demo

You are not here to click through a software tour. You talk to Ethan. He builds the system with you.

How a project is priced

Scoped up front. No retainer required.

Every system is scoped individually and priced up front. Live in 7 to 14 days. No required retainer after ship.

Hi, I'm Ethan.

I started Three Rivers AI because small businesses kept overpaying for technology that underdelivered.

The name comes from the Allegheny, the Monongahela, and the Ohio. Three rivers meet in Pittsburgh and become something bigger. That's the whole idea here: the right tools, the right plan, and the right build coming together into one thing that works.

Everything we build starts by learning how your business actually runs, then shaping the tool to fit it. Molded, not bolted on.

I'm one person, not an agency. You talk directly to the person building your system. Decisions happen in days instead of meetings. Nothing gets held hostage when we're done. Your accounts, your data, your control.

“I trusted Three Rivers AI with my first project as a new hire at my current position. Risky? Maybe, but they exceeded all of my expectations and did an unbelievable job in creating our software. I plan to do a lot more work with Ethan and his team. They made me look like a hero!”

Thank you, Anthony! It was a pleasure building your site, and I meant what I said: I'm always just a call away. Glad you love how it turned out, and I'm looking forward to keeping it running great for you.
