ABOUT US

The AI migration company for real estate and construction businesses.

FOS AI was founded in 2023 and works in the United States and Greece. Chicago and Illinois first, New York next. Here is what we believe: business owners should not have to become AI experts. Knowing AI is our job. We come into your company, install the AI systems that fit your case, teach every employee to use them, and maintain the setup as you grow. We serve the people who build: developers, general contractors, architects, roofing, plumbing, HVAC, and electrical companies. The name comes from the Greek word fos, which means light. Light inside your operations.

Revenue small and mid-sized firms lose to scattered operations and manual coordination

Hours per manager, per week, lost to admin coordination — before the migration

Days from first audit to a company that runs on AI — installed, taught, maintained

In short: we are the Chicago company that migrates building businesses into AI. Founded in 2023, working across the United States and Greece, and we only win when your team actually uses it.

WHY FOS AI

Why companies choose us for the move into AI

We Come To You

No slide decks and no generic advice. We work inside your company, at the office and on the job sites, and map how your business really runs before anything gets built. Then we install the AI structure around it: accounts, roles, permissions, knowledge base, and workflows. Firms in this industry lose 5 to 23 percent of revenue to scattered operations. The fix starts with someone who shows up.

We Teach Until It Sticks

Managers lose 19 to 29 hours a week to coordination. Software nobody uses gives none of it back. So every engagement includes live training, role by role, on your team's real work. The estimator trains on a real proposal. The PM trains on a real RFI. Adoption is the deliverable, not the license.

We Teach Until It Sticks

We Maintain What We Build

AI models change every few months. Your setup should get better, not older. We stay on after launch with monthly improvements, new workflows, help for new hires, and engine upgrades as stronger models ship. Everything we build stays yours: the structure, the playbooks, the knowledge base.

We Maintain What We Build

2023

FOS AI was conceived to solve real operational problems in real estate development and construction. The initial system was designed around document handling, invoices, project tracking, and on-site workflows, with early testing alongside real operational teams to validate practical use cases.

2024

FOS AI was deployed in closed environments for real estate developers and construction teams. The system was trained on real workflows such as invoice processing from photos, project cost tracking, reminders, and follow ups.

2025

FOS AI launched as a private, enterprise-grade AI system for real estate development and construction companies — then refocused on what clients need most: the full migration. We now install, teach, and maintain AI systems for the businesses that build — developers, contractors, architects, roofing, plumbing, HVAC, and electrical companies — with Chicago as our home market and New York next.
