So I built it.
In April 2026 a thread on r/AI_Agents hit 230 upvotes asking for exactly this — an AI that screens inbound leads for small services firms. A follow-up a week later pulled 105 more. Lawyers, consultants, designers — all describing the same six-step manual relay (read · qualify · re-type · reply · ping · chase) eating 20 minutes per lead.

I spent the next six weeks building it. A real SaaS — not a demo. Multi-tenant auth, per-workspace sending domains, Cal.com webhooks, AI classifier with vertical-specific prompts, an inbox with override + notes + follow-up drafting. Then I open-sourced the whole thing and made the hosted version $49/mo.
