$3,850/mo from a $0 automation agency (n8n + open LLMs + Twilio)
A builder reports $3,850 MRR from packaging self-hosted n8n plus open-source LLMs plus Twilio webhooks as an 'anti-lost-lead' service (instant SMS, booking, CRM sync) for local HVAC, dental and roofing businesses, on $14.20/month infra. Self-reported and unaudited, but the playbook is concrete: one painful repeatable job, productized, sold as a retainer.
