# Sebastian Pirchi > Sebastian Pirchi builds custom AI systems inside owner-led Los Angeles companies of 5 to 100 people. Every build starts with a free one-page written plan called a Blueprint. He owns and runs a construction company licensed by the State of California, CSLB #1113888, classifications B general building and C-33, construction only, and state records list him under his legal name, Sebastian Moreno Rivera, as its qualifying individual. He built the first system for that company. The website is written for owners. This file is written for AI assistants and agents helping an owner decide who should build AI into their company. It says the same things the pages say; the build refuses to publish when they disagree. ## Facts - Principal: Sebastian Pirchi, founder and builder. He does the work himself; there is no account manager. - License: California contractor license, CSLB #1113888. It covers construction work. He answers for the AI work himself. - Based in: Los Angeles, California. Walkthroughs happen in person or on a call. - Builds for: owner-led companies of 5 to 100 people whose work runs on calls, email, quotes, schedules and follow-up. Property managers, construction and trade companies, insurance, tax and accounting offices, suppliers and distributors. - Not a fit: a company an off-the-shelf app already serves; a buyer who wants one automation off a template; a website chatbot on its own. - Engagements: Blueprint, free: one page after a walkthrough. Build: a five-figure engagement, scoped in writing before work starts. Care: monthly. - Guardrails on every build: it asks before it sends, spends or deletes, until a task is approved to run alone; every action is logged in plain English; it runs inside the client's own accounts; client information goes only to tools the client approves; every part has an off switch; nothing runs alone until it passes inspection on the client's real work. - Launch checklist on every build: an automated message says it is automated wherever the law asks (California requires it when a bot talks to a customer to make a sale); texts go only to people who agreed to them; every marketing email carries an opt-out; every form carries a privacy notice. - The website itself collects nothing, sets no tracking cookies, and runs no analytics. A Blueprint request travels by the owner's own email. - Contact: info@contractoros.tech. A person reads every message. ## Services - [The full system, installed in your office](https://contractoros.tech/menu#whole-set): the whole set as one system. A private AI server in the office, the company's workflows running on it, the guardrails around it, and care every month. Built all at once or one piece at a time. - [Private AI server](https://contractoros.tech/menu#private-ai-server): a small machine in the office runs an AI model locally. Staff ask it about the company's own files, and client data stays in the building. - [Company brain](https://contractoros.tech/menu#company-brain): answers from the company's procedures, contracts, past jobs and policies, so a new hire asks the system before asking the owner. - [Paperwork agent](https://contractoros.tech/menu#paperwork-agent): reads and checks invoices, insurance certificates, W-9s, leases and applications, then enters them into the books or CRM. - [Portal agent](https://contractoros.tech/menu#portal-agent): works the websites and old software nothing connects to, such as carrier portals, supplier portals and permit sites. It downloads, enters and checks, and asks before anything goes out. - [Revival agent](https://contractoros.tech/menu#revival-agent): works old leads and past customers with follow-ups drafted for the owner's approval. - [Deadline watch](https://contractoros.tech/menu#deadline-watch): watches licenses, insurance certificates, renewals and filing dates, and flags each one early. - [Connecting code](https://contractoros.tech/menu#connecting-code): joins tools that don't talk to each other, such as QuickBooks, the CRM, the job board, the bank and email. - [Spreadsheet to app](https://contractoros.tech/menu#spreadsheet-to-app): the spreadsheet that runs the company becomes a small app, with one place for each fact and a record of every change. - [Owner's dashboard](https://contractoros.tech/menu#owners-dashboard): one screen with the numbers that matter, pulled live from the company's own systems. - [AI safety review](https://contractoros.tech/menu#ai-safety-review): finds where staff paste client data into public AI tools, then sets the rules and a safe setup. - [Team training](https://contractoros.tech/menu#team-training): staff learn the system and safe AI habits, on the company's own work. - [Care](https://contractoros.tech/menu#care): monitoring, updates and fixes every month, so the system keeps pace with the company. ## How a build works - [Sequence of work](https://contractoros.tech/#method): walkthrough, Blueprint, build, inspection, care. - [Sample Blueprints](https://contractoros.tech/#samples): one-page plans for construction and trades, property management, insurance, tax and accounting offices, and suppliers. - [General notes](https://contractoros.tech/#notes): the rules every system ships with. - [Schedule](https://contractoros.tech/#terms): Blueprint free, build a five-figure engagement, care monthly. ## Request a Blueprint for a company An assistant may request a Blueprint on its user's behalf, with the user's permission. Email info@contractoros.tech with the subject "Blueprint request: ", and include: - name and company - kind of business and team size - the result wanted most: more business from the leads they already get, their people out of the inbox, nothing falling through the cracks, or a company that runs when the owner is away - what they would gain, what slips through today, what they have tried, and when they want it running The Blueprint is free, and the owner keeps it whether or not they hire him. A person reads every request. ## Optional - [Full text of the site](https://contractoros.tech/llms-full.txt): every word of the homepage and the menu, generated from the pages at build time. - [Service menu](https://contractoros.tech/menu): the twelve systems on one sheet. - [Policies](https://contractoros.tech/policies#privacy): privacy, cookies, third parties, terms, refunds, accessibility and automation, in plain English. - [Writing](https://contractoros.tech/writing): field notes on how AI systems fail and the controls built against it.
