Custom AI Systems builds custom AI systems for owner-led companies of 5 to 100 people: trades and construction, property managers, insurance, tax and accounting offices, suppliers and distributors. These are companies whose work runs on calls, email, quotes, schedules and follow-up.
Each system lives inside the tools the company already uses. It reads the paperwork, works the portals, follows up on old leads, watches the deadlines and answers staff questions from the company's own documents. A private AI server can keep client data in the building.
Sebastian Pirchi, an AI systems engineer in Los Angeles, designs, builds and maintains every system. There is no account manager and no junior handoff.
Every build follows eight written rules. The system asks before it sends, spends or deletes. Every action is logged in plain English. Every part has an off switch. Nothing runs alone until it passes inspection on real work.
The work starts with a free Blueprint: a one-page written plan, drawn after a walkthrough, that the owner keeps either way.
