You already know the process. That was the hard part.

Every piece of software you rent was written by someone who has never been on your roof at 6am in February, never chased a part across three supply houses, never had to explain to a customer why the compressor is short-cycling.

So it fits badly. You bend your work to match the software, pay a monthly fee for the privilege, and the one feature you actually need has been "on the roadmap" for two years.

Claude changed the arithmetic on that. The knowledge that used to gate building your own tools — syntax, frameworks, deployment — is no longer the bottleneck. Knowing what the thing should do is the bottleneck, and you've had that the whole time. This is a shop that sits down with people who know their trade and builds the tool they were about to rent.

Already running

Not mockups. These are in production, doing work every day.

DSM
Full contractor operations platform — jobs, quotes, proposals, service history, payments, margins. Runs on a Raspberry Pi in the office. Replaced a field service SaaS subscription outright.

Field quote parser
Photograph a nameplate and a survey sheet on site, get a drafted quote with line items before you're off the roof.

Tempi
A site assistant that answers like a dispatcher instead of a chatbot — triages the problem, routes the lead, books the call.

AUTAS
Market news classifier with voice briefings and alerting. Reads the tape so you don't have to sit on it all session.

How a build goes

Walk the job

An hour on the phone or in your shop. What do you do all day, where does it jam up, what are you paying for that you resent.

One page of spec

Written in your language, not in tickets. If it doesn't fit on a page it's two projects and we'll say so.

Working version, not a demo

Days later you get something with your real data in it. You use it, you find what's wrong, we cut what nobody touches.

Handed over

Code, database and deployment are yours, on your hardware or your account. No seats, no export fee, no hostage data.

Caution — read before energizing

What this isn't

  • It isn't magic. Claude writes and debugs fast, but somebody still has to know whether the output is right, and that somebody is going to be me and you.
  • It isn't free of upkeep. Software you own is software you maintain. Less than a subscription, more than nothing.
  • It isn't a fit if your process is genuinely standard. If off-the-shelf already fits you, keep it and save your money.
  • It isn't a headcount replacement. It removes typing, chasing and re-entry. It doesn't remove judgment.
