If you are closing voice AI deals faster than you can build them, this is for you. You keep the client & the relationship. I build. Why I am useful to an agency specifically. I have run the other side. I took a services company to $545,000 with 25 remote workers, managing storefronts that did over $5M. A platform rule change broke the unit economics overnight, I cut the team 75% to survive it, & rebuilt the whole front office on automation. I know what it costs you when a build slips, because I have been the one explaining it to the client. What I take on. - Retell builds end to end. Custom-LLM WebSocket rather than the visual builder, so pacing, turn-taking & interruption handling are things I change in code. About 1.5 seconds warm to first audio in production. - Backend integration that does not lie. Tool-calling into real calendars, POS & CRM, with every write failing closed. Your agent never tells a caller it booked something it did not. - n8n orchestration, SMS & email lifecycle, A2P 10DLC, the unglamorous plumbing. - An eval harness in front of every deploy. Golden scenarios in a database, deterministic grading, an LLM judge on conversation quality. On my own build the unqualified-lead gate holds 4 of 4 & abuse hard-stops 3 of 3. That last one is the part agencies underrate. The thing that burns a client relationship is not a clunky agent. It is an agent that reports success on a write that failed, & nobody finds out for a week. I have been up at 2am with a client’s phone line down & no way to tell how long it had been down. It cost me a night & a lot of trust. Everything above exists because of that. White label, your name on it, I stay invisible. Fixed scope per build or a monthly retainer if you have steady flow. If you send me a build & I think your in-house person could do it in an afternoon, I will say so. DM me here. ---

Correction to the original post. The verified Done For You LLC result is $649,206 gross in 2024, with 25 remote workers and more than $5M in combined client storefront revenue managed. After a platform policy change forced a 75% team reduction, I recovered with a 2,000-lead reactivation that produced $94,000 in one December. My current product proof is one client and $2,000 collected total, plus 76 edge functions, about 140 Postgres tables, about 1.5 seconds warm time to first audio, 4 of 4 on the unqualified lead gate, 3 of 3 abuse stops and 12 of 12 on the AI CRO eval suite. The retired revenue figure, unsupported outage story and workflow tool reference in the original post are not current evidence and should not be relied on. The forum edit window is closed, so I am requesting moderator removal of the original. The offer remains: white-label Retell builds, custom LLM WebSocket work, calendar, POS and CRM tool calls, SMS and email lifecycle automation, A2P 10DLC and an eval harness before deployment. You keep the client relationship and I stay invisible. Fixed scope or monthly retainer after scope. Message me here.
