From here to a product that moves minds.

We work out what the business really needs and build it, front to back, so people use it.

Three ways in

Which one sounds like you?

You've got a half-built product and nobody to finish it.

We finish it and take it live.

Maybe it's an idea, or a demo that isn't a product yet. We build the whole product around it. That means the app people use, the servers, billing if you charge for it, and launch chores like getting phone carriers to approve your texts. It's set up so it stays yours, down to the accounts and keys.

Something's stuck, or a bill keeps climbing.

We find what's holding it up and fix it.

Maybe billing isn't live yet, or the cloud bill jumped and you can't tell what's eating it. Or the launch is waiting on a security review. We find the cause and fix it, then tell you in plain words what changed. We work right in your repo and your chat, so your team sees every change.

You need engineers in your codebase now.

Engineers ship in your code, then your own team takes it over.

We put the team together and lead it from inside your company, in your code and your chat. Each engineer gets a part of the product to own, and every pull request runs the same checks. Then we hand it over.

The Genie Marie home page: a stitched name patch that reads Marie, above the headline: The office help you never got to hire. Below it: Meet Marie. An AI assistant on your office's own number.
From geniemarie.com, captured Nov 12, 2026.

Our flagship · Live

Genie Marie answers a shop's texts.

An AI assistant on a shop's own text number. She answers customers first, then brings in the owner.

We built her for owner-run trades and service shops. A customer texts the shop's number, Marie answers and says she's an AI assistant, and the owner gets the short version.

Answering customer texts is the job that works today. The other four jobs get built with each shop.

After you write

What happens next

  1. You tell us what you need

    One sentence is enough. You'll usually get a question back.

  2. We take it from there

    If there's real work in it, we take it on, and if it needs a team, we put one together. We won't quote you in a first email. You decide if there's a next step.

  3. We write the plan

    Before anything gets built, we write down what's there, what changes, and how you'll know it worked. Then we set up your GitHub organization, hosting, database and keys.

  4. You can watch the work

    Our changes run through automated checks and a review by a second AI model before we decide what ships. On a full build you get a status page that updates while we work, so you can see where things are without asking.

  5. Your team runs it

    We set it up so your team can keep shipping, and we stay on call.

Who you work with
