  2. CallerHi. I have a water stain on my bedroom ceiling after the rain last night.
  3. AI agent (Riley)I'm sorry to hear that. It sounds like you might have a leak. Let's get that checked out as soon as possible. Could you tell me which town or area you're in?
  4. CallerI'm in Egg Harbor Township.
  5. AI agent (Riley)Thanks. And do you know how old your roof is, roughly?
  6. CallerIt's about 18 years old.
  7. AI agent (Riley)Got it. Since this might be urgent, let's schedule an inspection quickly. I can offer you a slot tomorrow at 10 a.m. or Friday at 1 p.m. Which works better for you?
  8. CallerTomorrow at 10 a.m. works.
  9. AI agent (Riley)Great choice! I'll book that for you. Could I have a made-up name and number for this demo booking?

  1. AI agent (Riley)Hi, this is Riley calling from Ridgeline Roofing. Just so you know, I'm an AI assistant, and this is a demo call. I'm following up on the roof replacement estimate Mike sent over last week. Is now an okay time for a quick minute?
  2. HomeownerYeah, that's fine. I just had a quick question about financing.
  3. AI agent (Riley)Great! We do have financing available through a third-party lender, and it's subject to approval. Mike can definitely walk you through all the options and details.
  4. HomeownerOkay, so Mike can tell me more about it? I'd like to talk to him.
  5. AI agent (Riley)Absolutely! Mike can certainly go over all the financing options with you. Would tomorrow, Friday, October 16th, at 10 AM Eastern, or Monday, October 19th, at 2 PM Eastern work better for a quick call with him?
  6. HomeownerTomorrow at 10 AM works for me.
  7. AI agent (Riley)So, to confirm, I'll put you down for a call with Mike tomorrow, Friday, October 16th, at 10 AM Eastern. Since this is a demo, we'll just use a made-up name and number for now. Mike will be happy to discuss the financing options with you then.

  9. AI agent (Riley)So, to confirm, I'll put Dana Lee down for a call with Mike tomorrow, Friday, October 16th, at 10 AM Eastern, at 609-555-0142. Just a reminder that this is a demo booking, so nothing is actually scheduled on a real calendar. Thanks for your time, and Mike will be in touch!

Browser demonstrations of our phone agents. In a real setup your customers reach them by phone; we don't sell website chat. Demo agents never book, call, text or email anyone.

The problem

You're not short of leads. You're short of replies and follow-ups.

Inquiries come in after hours, on weekends and while your team is busy. Quotes go out and nobody checks back. Past customers drift away without being asked to come back. Nothing looks broken, but money is lost at every one of these points.

  • Slow replies

    A caller who reaches voicemail often rings the next business on the list.

  • No follow-up call

    Most quotes and inquiries never get a call back. People mean to, but don't get round to it.

  • Silent churn

    Past customers leave without anyone noticing or asking them back.

What we build

Two agents, working as one team.

Both are trained on your business: your services, prices, policies, tone and calendar. They talk to your customers on the phone, in a natural voice built with ElevenLabs.

Front desk

AI Assistant

Answers your phone, qualifies callers and books appointments while they're still on the line.

  • Answers every call 24/7, including after hours and when your line is busy
  • Answers from your own knowledge base, not guesswork
  • Asks the qualifying questions you'd ask
  • Books straight into your calendar during the call
  • Hands over to a person, with the full context, when it should

Follow-up

Follow-up Agent

Calls back so no lead, quote or customer is forgotten.

  • Calls back unanswered inquiries and open quotes
  • Calls to confirm appointments and reschedules no-shows
  • Checks in by phone after the sale and asks for a review
  • Calls past customers who've gone quiet
  • Only calls people who agreed to be contacted, and stops when they book, buy or ask not to be called
  • Phone calls, inbound and outbound
  • Google Calendar / Calendly
  • HubSpot / your CRM

Where follow-up pays

Five moments where leads go cold.

We start with the moments where your business is losing customers today and set up an agent for each one.

  1. 01

    New inquiry

    Someone calls with a question. A specific answer, the qualifying questions and a booked appointment, on the same call.

  2. 02

    Quote sent

    The proposal is out and the silence starts. Timed follow-up calls that answer questions and ask for a decision.

  3. 03

    Booking & no-show

    A reminder call before the appointment, and a polite call to reschedule instead of losing the customer.

  4. 04

    After the sale

    A satisfaction call and a review request, made when the customer is happiest.

  5. 05

    Gone quiet

    Past customers who stopped buying or booking. A personal call with a reason to come back, never to people who opted out.

How it works

Five steps, one of them human.

  1. 01

    Discovery call

    20 minutes. We map how calls come in, how you follow up today and where customers drop off.

  2. 02

    Follow-up audit

    We review your current replies and follow-up and give you a prioritised plan before anything is built.

  3. 03

    Build & train

    We connect your phone line, calendar and CRM, and train the agents on your services, prices, policies and tone.

  4. 04

    A person tests it

    No agent goes live unchecked. I test it against real scenarios, edge cases and handover rules, and you approve it.

  5. 05

    Live & improving

    Monthly review of calls, missed questions and results. The agents get better each month.

Guardrails

Automation where it helps. A person where it counts.

No made-up answers

The agent only answers from information you've approved. If it doesn't know, it says so and passes the question to your team.

Clear handover

Complaints, complex cases and high-value deals are transferred to a person, with the call summary attached.

You stay in control

You approve the tone, the script and how often it calls. Do-not-call requests are respected immediately, and you can pause it at any time.

Pricing

One setup fee. Then monthly. No long contracts.

Every plan includes setup, training, testing by a person and a monthly review. Cancel with 30 days' notice.

Who builds your agents

One person, name attached.

I'm Antonio Palomero. I spent years auditing ecommerce lifecycle and retention flows, where I kept finding the same problem: the follow-up nobody sent. Retention Foundry now builds the agents that send it. I set up and review every agent myself before it talks to your customers. I'm based in Palma, Spain, and work in English and Spanish.

Questions

Before you book.

What kind of businesses is this for?
Businesses where customers call and sales depend on calling back: clinics, home services, agencies, professional services, real estate and hospitality. If one missed call can mean one lost customer, it's a fit.
Will customers know they're talking to AI?
Yes. We recommend being open about it, and it's required in many places anyway. In practice, customers care more about getting a fast, useful answer, and the agent hands over to a person whenever it should.
What if the agent gets something wrong?
It only answers from information you've approved, follows strict handover rules and is tested by a person before launch. Every month we review its conversations and fix any gaps.
What do you need from me?
A 20-minute call, access to your phone line and calendar, and your service details, prices, policies and FAQs. We write the knowledge base from those and you approve it.
How long until it's live?
Usually about 2 weeks from kickoff, including testing and your approval.
Does it work with my current tools?
Most likely. We work with your existing phone number and connect to common calendar and CRM tools. If something isn't supported, we'll tell you on the first call.
What about data and privacy?
We use only the access the agent needs, work under a GDPR-compliant data processing agreement and never use your customers' data for anything else. You can revoke access at any time.
Is there a long contract?
No. You pay the setup fee once, then monthly, and can cancel with 30 days' notice.
