INTERVIEWER
You said job numbers in JobNimbus never match QuickBooks. When they disagree, which one do you trust?
YOU
QuickBooks. That's what my accountant sees. JobNimbus is where the crews live.
INTERVIEWER
Got it. Drop that warranty spreadsheet here while we talk and I'll map it in the background.

Software that fits the way you already work.

Off-the-shelf tools make you work their way. Custom software used to take a developer and six months. Now it takes a conversation.

Built from your words
Every screen traces back to something you or your team said.
Yours, not rented
Your own database, your own domain, your company's name on it.
Connected on day one
Your books, your inbox and your old spreadsheets, brought in for you.
Better every month
Every OS runs on one shared core, so each improvement reaches you too.
How it works

Other tools hand you a blank screen.We hand you your company.

The interviewer asks the questions a seasoned builder would: which number is true, which date counts, who needs to see what. You just answer.

You talk for 30 minutes. A person signs off on the plan before anything is built.

  1. 01
    The Walkthrough

  2. 02
    The Blueprint and the Model Home
    A plan you can read, and a walk-through of your OS with your name, your modules and sample data shaped like your business. Free, before you pay anything.
  3. 03
    Walk through it with a person
    A 20-minute call to go over the Model Home, settle the price and sign.
  4. 04
    Get the Keys
    Connect your systems, invite your team, and get a morning digest of what needs you. Need more later? Ask for a Remodel.

Works with what you already use.

Click Connect, sign in, done. Old spreadsheets get their columns mapped for you, and anything that looks wrong gets flagged before it goes in.

A person checks every build.

A builder signs off on the plan
An experienced builder reviews every spec before anything is made. AI does the work; a person owns the judgment.
Security checked before launch
Sign-in, permissions and every record's access rules are tested before your team ever logs in.
Your data stays in your system
Your own database, connections stored encrypted, and nothing real goes in until you've signed.

Questions owners ask.

Do I need to know anything technical?
No. You talk about your business the way you would to a new manager. The interviewer handles the rest.
What if the AI gets it wrong?
You see the preview before you pay, and a builder reviews every plan before it's built. Anything off gets fixed on the closing call.
Who owns it?
Your data is yours, in your own database, and you can export it anytime. The platform underneath is licensed to you.
Can my team use it?
Yes. Invite everyone, and each person sees only what their role allows.
What happens when we need something new?
Ask for a Remodel: a short conversation, and the new module is added to the OS you already run.
We handle patient or bank data. Is that okay?
Not yet. We're starting with businesses that don't hold patient or bank records. Tell us about yours and we'll let you know when we're ready.

Tell us how your business runs. We'll show you the system.

Thirty minutes, from your phone. The preview is free.
