proof library / lead pipelines

Lead pipelines, mapped.
Source to handoff, with the failure states.

Sample pipelines from the lead source to the moment a human takes over. Each one shows the trigger, the steps, what the dashboard records, how it behaves when a step fails, and what a run costs. This is an operational system, not just an AI call. Built in code, so it stays debuggable and yours.

Read each map top to bottom. The numbered steps are automatic. The handoff row is where a person steps in. Cost-per-run figures are directional, based on typical token and telephony usage.

01 · Meta lead ad to booked call

Lead-gen
Source
Facebook / Instagram Lead Ads
Trigger
Lead form submitted, webhook fires
01Webhook verified (HMAC), lead written to the database with an idempotency key
02SMS within 10 seconds, asking to confirm a time
03AI voice agent calls, qualifies, collects location and availability
04Stage updated, recording and transcript attached to the lead
Human handoff
On a qualified lead: live transfer to the front desk, or a callback task if no one picks up
Dashboard
Funnel count, lead row, call status, source ad, next action
Failure handling
Missed call retries on a schedule then stops; an inbound text still routes to a human
Cost per run
~$0.20 to $0.60 per lead, mostly call minutes
Stack
Supabase, Vapi, Claude, Twilio, Resend, Vercel

02 · Website form to CRM to booked call

Inbound
Source
Contact or demo form on the site
Trigger
Form submit
01Lead enriched: name and company looked up, fit and urgency scored
02Written to the CRM with a stage and an owner
03High-fit leads ping the right person on Slack with a recommended action
04Follow-up email or SMS sequence starts automatically
Human handoff
On a high-fit lead: Slack alert with the enriched summary and a one-click reply draft
Dashboard
Lead list with fit score, source, stage, last touch
Failure handling
Enrichment timeout falls back to the raw form; nothing is dropped
Cost per run
~$0.02 to $0.10 per lead
Stack
Supabase, Claude, web search, Slack, Resend

03 · Lead magnet to email to checkout

Self-serve
Source
Lead magnet (PDF, calculator, or guide)
Trigger
Download or email capture
01Asset delivered instantly, subscriber tagged by source
02A short nurture sequence: problem, proof, soft offer
03Checkout via Stripe; webhook confirms payment
04Buyer moves to onboarding; the nurture sequence stops
Human handoff
Optional: high-value carts route to a personal email instead of automation
Dashboard
Subscribers by source, sequence position, conversion to paid
Failure handling
Failed payment retries and notifies; delivery is idempotent, no double sends
Cost per run
~$0.01 per subscriber plus payment fees
Stack
Supabase, Stripe, Resend, Vercel

04 · Missed call to AI callback to staff alert

Recovery
Source
Inbound phone call that no one answered
Trigger
Missed-call event from the phone provider
01AI agent calls back quickly: "you just called, how can we help?"
02Captures the reason, intent, and a good callback time
03Writes a CRM note and creates a task
04Texts the caller a confirmation that the team will follow up
Human handoff
Always: a staff alert with the captured reason and the best callback time
Dashboard
Missed-call queue with reason, status, and assigned owner
Failure handling
No answer on callback leaves a voicemail and a text, then flags for manual follow-up
Cost per run
~$0.15 to $0.40 per recovered call
Stack
Twilio, Vapi, Claude, Supabase, Slack
