Sales · Do this yourself

Revive old leads for car dealers and local businesses with AI follow-ups.

In short: an AI-agent-run business you oversee about an hour a week. Tools cost $77–$107/mo, agent setup is intermediate, and the source reports $1,000 setup + $250/month from the first dealership client (self-reported, r/AiAutomations) (self-reported).

How it makes money: Charge dealers and local businesses a setup fee plus $250/mo to re-contact old leads and book the ones who reply.

Where this came from (Reddit)

Businesses pay for leads, contact them once or twice, and leave the rest sitting untouched in their lists.

The threads (in our words)

  • Two cofounders landed their first paying client after four months: a car dealership spending about $10k a month on inbound leads that were not followed up well, now paying $1,000 setup plus $250 a month for an AI lead-nurturing system.

  • A young AI agency founder says follow-up is an unfair advantage: after the ads were switched off, most of their next two months of revenue came from following up old leads that had only been contacted once or twice.

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. Revenue figures are the poster’s own claim (self-reported), not verified. The business below is our own design inspired by these threads.

Who it’s for

Car dealers, home-service companies and clinics with a long list of past enquiries.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. Export the leads that went quiet in the last 12 months and remove anyone who opted out.
  2. Have the agent write a short, honest check-in by text and email that mentions what each person asked about.
  3. Send in small daily batches with an opt-out in every message and quiet hours respected.
  4. Let the agent sort replies into interested, later and stop, and book interested people onto the sales calendar.
  5. Charge a setup fee plus a monthly fee through Stripe, and report revived conversations and booked visits every week.
  6. Recycle the “later” replies into a gentle 60-day follow-up.

What they did

An agent re-contacts leads that went quiet by text and email, sorts the replies and books the warm ones back in for the sales team. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.

How it went

Found on Reddit in r/AiAutomations, r/EntrepreneurRideAlong (2 threads). Upvote and comment counts weren’t retrievable, so none are shown. On X, 124 posts matched our search for this idea in the 7 days to 2026-10-19.

Worth knowing

Only message people who gave consent; follow SMS and anti-spam rules (TCPA in the US), honor opt-outs at once, and never pretend the agent is a human salesperson.
