Custom AI SystemsLos Angeles

Custom agentic AI for owner-led companies

I build the AI that runs your office, so you can run the company.

Custom agentic systems for companies of 5 to 100 people. They answer every inquiry, chase every open quote and invoice, keep your records current, and put one page on your desk each morning with what needs your yes.

Built inside the tools you already use, by a builder who made it for his own licensed construction company first.

The Blueprint is a one-page written plan for your company: what to automate first, in what order, and what it takes. It is free and yours to keep. The build it describes is separate, and paid.

02Program

Start with the result you want

Every build starts from one result, in your words. Pick yours. The work follows from it.

Revenue

“More business from the leads we already get.”

What I install
An intake agent that picks up every call, text, email and web form, asks your questions and books the next step. A follow-up agent that works every open quote until you hear yes or no.
What you see
Every lead in one list: where it stands, and who owes the next reply.
Start my Blueprint here

Time

“My people out of the inbox.”

What I install
An operations agent that reads the email, turns requests into tasks, updates your records and drafts the replies for a person to approve.
What you see
One page each morning: what came in, what moved, what needs your yes.
Start my Blueprint here

Risk

“Nothing falls through the cracks.”

What I install
Agents that watch invoices, deadlines and paperwork, and start the follow-up before a date passes. Every action logged.
What you see
A short list of exceptions: the items that need a person.
Start my Blueprint here

Standing

“A company that runs when I'm not there.”

What I install
The whole system tied together, with your rules written in: who approves what, what goes out alone, what waits for you.
What you see
Answers at nine at night by the same rules your best person uses at nine in the morning.

03What I build

What I build

Twelve pieces in four groups. Each one can be built alone. Together they make one system.

The full system, installed in your office

The whole set as one system: a private AI server in your office, your workflows running on it, the general notes around it, and care every month. Build it all at once or one piece at a time; your Blueprint sets the order.

Private AI

Runs on a computer in your office. Client data stays in the building.

P1

Private AI server

A small machine in your office runs an AI model locally. Your staff ask it about your own files, and client data stays in the building.

P2

Company brain

Answers from your procedures, contracts, past jobs and policies, so a new hire asks the system before they ask you.

Workflows

Agents that do the office work, inside the tools you already use.

W1

Paperwork agent

Reads and checks invoices, insurance certificates, W-9s, leases and applications, then enters them into your books or CRM.

W2

Portal agent

Works the websites and old software nothing connects to: carrier portals, supplier portals, permit sites. It downloads, enters and checks, and asks before anything goes out.

W3

Revival agent

Works old leads and past customers with follow-ups drafted for your approval, starting from a list you already own.

W4

Deadline watch

Watches licenses, insurance certificates, renewals and filing dates, and flags each one early.

Custom code

Software written for your company, running on your own accounts.

C1

Connecting code

Joins the tools that don't talk to each other: QuickBooks, your CRM, the job board, the bank, email.

C2

Spreadsheet to app

The spreadsheet that runs your company becomes a small app, with one place for each fact and a record of every change.

C3

Owner's dashboard

One screen with the numbers that matter, pulled live from your own systems.

Safety and people

The rules, the training and the upkeep.

S1

AI safety review

Finds where staff paste client data into public AI tools, then sets the rules and a safe setup.

S2

Team training

Your staff learn the system and safe AI habits, on your own work.

S3

Care

Monitoring, updates and fixes every month, so the system keeps pace with the company.

The same twelve on one sheet you can print or send: the service menu.

04Sample plans

What a Blueprint looks like

A Blueprint is one page, drawn for one company. These samples show its shape for four kinds of business. Yours names your people, your tools and your numbers.

Sample Blueprint · Construction & tradesIllustration only

Goal

“More signed jobs from the leads we already pay for.”

Existing conditions

  • Leads hear back the next day, after they have called someone else.
  • Estimates take a week to leave the office.
  • Sent quotes go quiet, and nobody follows up.
  • Change orders and invoices get chased on weekends.

New work

  • Intake agentPicks up every call, text, form and lead-site message, day or night, asks your qualifying questions, and books the walkthrough.
  • Estimate assistantTurns walkthrough notes and photos into a draft estimate in your format, ready for your review.
  • Follow-up agentSees when a customer opens the quote and follows up until you hear yes or no.
  • Collections agentSends progress invoices and reminders on schedule, after your approval.

Inspection

Drafts every reply for your approval on live leads. It sends on its own only where you approve it.

Timeline and investment: set in your Blueprint, in writing, before any work starts.

05Site

Custom, built on your lot

Off-the-shelf apps are the same house built a hundred times: good houses, one floor plan for everyone, and your company learns to live the way the plan says. I build custom. On your lot, around the way your company already works, with your tools, your rules and your people.

A fit if

  • You run a company of 5 to 100 people.
  • The work runs on calls, email, quotes, schedules and follow-up.
  • You are the bottleneck, and you know it.
  • You want your best people on the work only they can do.

Not a fit if

  • An app off the shelf already does the job. Buy the app.
  • You want one automation off a template. Plenty of people sell those.
  • You want a chatbot on your website and nothing more.
  • You want it built without a conversation.

06Sequence of work

Built the way I build a building

Drawings before work. Inspection before handoff. Care after. Owners already trust that order on a job site, and it keeps a five-figure build honest.

  1. 01

    Walkthrough

    We walk through your company together, in person or on a call: the inbox, the phones, the handoffs, the spreadsheets. I ask a lot of questions.

    You getA clear read on where the hours go.

  2. 02

    Blueprint

    One page: what you want, where the hours go, what I would install, how it gets inspected, the timeline and the investment.

    You getThe plan. Free, and yours to keep.

  3. 03

    Build

    I install the agents inside your tools and write down the rules: what each one may do alone, and what waits for a person.

    You getA working system on your own accounts.

  4. 04

    Inspection

    The system works beside your team on real work, drafting only. It acts alone only where it has proved itself and you approve it.

    You getProof on your own work before anything runs alone.

  5. 05

    Care

    I watch it, tune it and fix it, month after month. When your business changes, the system changes with it.

    You getA system that keeps working after the build.

07General notes

The rules it ships with

These notes come with every build. My own company's system runs on the same rules.

General notesApply to every sheet

  1. It asks before it sends, spends or deletes, until you approve a task to run alone. You decide, task by task.
  2. Every action is logged in plain English: what it did, when, and why.
  3. It runs inside your accounts. Your data, your customer list and your records stay yours.
  4. When it is unsure, a person decides, with a draft already written.
  5. Client information goes only to tools you have approved.
  6. Every part has an off switch. Turn one off and that work returns to your team.
  7. Nothing runs alone until it passes inspection on your real work.
  8. Before it goes live, every build passes a launch checklist: it says it is automated wherever the law asks, texts go only to people who agreed to them, every marketing email carries an opt-out, and every form carries a privacy notice.

08The builder

Who builds it

I'm Sebastian Pirchi. I own and run a Los Angeles construction company licensed by the State of California, CSLB #1113888, classifications B general building and C-33, construction only. State records list me under my legal name, Sebastian Moreno Rivera, as its qualifying individual. I built a system of AI agents to run the business side of that company: leads, estimates, follow-up and the books.

Then I did what a builder does after a job. I inspected it, tracked where it failed, fixed it, and published what I learned.

You work with the person who designed the system, built it and stands behind it. No account manager. No handoff.

10Questions

Questions owners ask

What does agentic mean?

Agentic AI does the task. It reads the message, checks your records, follows your rules and acts, or drafts the action for a person to approve.

What can you build?

Twelve pieces in four groups: private AI (a private AI server and a company brain), workflows (paperwork, portal, revival and deadline agents), custom code (connecting code, spreadsheet to app and an owner's dashboard), and safety and people (an AI safety review, team training and monthly care). Each can be built alone; together they make one system.

Can the AI run on our own computer?

Yes. A private AI server runs a model on a machine in your office, so client data stays in the building. Your Blueprint says which work runs there and which uses outside services you approve.

Do we have to switch software?

Usually no. I build inside what you already use: email, phones, calendar, your CRM and your books. If a tool can't do the job, the Blueprint says so before you spend anything.

What does a build cost?

Builds are five-figure engagements. Your Blueprint names the exact investment, in writing, before any work starts. The Blueprint itself is free.

Can I skip the Blueprint and just hire you?

Yes. Email me at info@contractoros.tech and we start with the walkthrough instead of the form. The Blueprint still gets drawn, because the build needs a scope, and it becomes the document we both work from.

How long does a build take?

Your Blueprint sets the timeline. Much of it is inspection, because the system works beside your team on real work before it works alone.

What if it makes a mistake?

It asks before anything important goes out, and it logs every action. During inspection it drafts only. When it is unsure, a person decides.

Whose data is it?

Yours. The system runs inside your accounts, and client information goes only to tools you approve.

Is it legal to let AI answer my customers?

Yes, with rules, and every build follows them. In California, an automated system that talks to customers to make a sale has to say it is automated. Marketing texts need the customer's consent, and marketing emails need an opt-out. Your Blueprint names the rules that apply to your business.

Do you only work with contractors?

No. I built the first system for my own construction company. Property managers, offices and suppliers run on the same things: calls, email, quotes, schedules and follow-up.

Why hire a contractor to build AI?

Because I built it for my own company first, and I build it the way I build anything: drawings, inspection, care.

11Request

Request your Blueprint

The same questions I ask on a walkthrough. Only your name and company are required; the rest makes the Blueprint sharper. I read every request myself.

Already decided? Skip the form. Email info@contractoros.tech and we start with the walkthrough.

This fits you if you are the owner or an officer, your company runs 5 to 100 people, and you already know a build is a five-figure engagement. I take on a few builds at a time, so every one gets me.

The result you want most
When do you want it running?

Rather talk first? Email two times that work, and I will call you.
