In plain English

Plumbers, electricians, heating and cooling contractors, and similar home-service shops hire Northbridge Logic, run by Simeon. The service sets up phone helpers, follow-up with people who asked about a job, customer messages, and appointment booking. Customers pay a setup fee and then a monthly fee, because the owner wants those calls and messages handled without a much bigger office. The work is split about evenly: the AI drafts and runs a lot of the communication, while a person still reviews what goes out. Simeon checks quality and grows the service through case stories and referrals.
