AI Voice Receptionist for real estate teams — and residential-plumbing missed-call recovery
CSJ US LLC operates two related services for small Texas businesses: an AI Voice Receptionist that answers a real estate team’s overflow and after-hours calls (captures the lead, books showings, texts the agent), and a Revenue Leak Snapshot & 14-Day Pilot for residential service plumbers (the original vertical, still operating at plumbers.csj-us.com). Same operator. Same compliance framework. Same SMS program.
What CSJ US LLC does
1. AI Voice Receptionist for real estate teams (current focus)
Texas-based real estate teams that are missing buyer or seller calls because the agent is in showings, in negotiations, or off the clock. CSJ US LLC’s AI receptionist answers in the agent’s voice, captures the buyer’s name and property of interest, books a showing on the agent’s calendar, and texts the agent a lead summary within sixty seconds. First active client: a North Texas realtor at 709 Bridget Way, Hurst.
2. Plumbing missed-call recovery (legacy vertical)
The original CSJ US LLC service, still operating at plumbers.csj-us.com. Independent residential service plumbers in Texas use the Revenue Leak Snapshot calculator and 14-Day Pilot to estimate and recover revenue lost to missed inbound calls. Same legal entity, same operator, same SMS program described below.
CSJ US LLC does not buy or sell consumer data, does not run affiliate programs, and does not purchase or rent lead lists. All onboarding, agreements, and billing happen one-on-one with the operator.
About CSJ US LLC and the multi-vertical structure
CSJ US LLC is a Texas LLC operated by Chad Colter, a licensed Texas Professional Engineer and Texas Real Estate Sales Agent (License 765129-SA). The company began with residential plumbing missed-call recovery (the “plumbers” vertical, hosted at plumbers.csj-us.com) and has expanded into AI Voice Receptionist services for real estate teams in 2026.
The two verticals share one legal entity, one operator, one compliance framework, one Privacy Policy, one Terms of Service, and one SMS program. They are intentionally cross-linked so users can verify the provenance of either service. SMS sender number (817) 813-6374 is registered to CSJ US LLC and is used for both verticals.
If you reached this site from a real estate prospecting outreach, the AI Voice Receptionist is the relevant service. If you reached this site from a plumbing missed-call recovery outreach, please use plumbers.csj-us.com directly — that subsite has the calculator and pilot enrollment specific to the plumbing vertical.
