Follow Up With Every Lead in Seconds. Reactivate Every Past Client.

The average business follows up with a new lead once or twice before giving up. The average sale requires five to eight touchpoints. That gap — between how many times businesses follow up and how many times it takes to close — is where revenue disappears. Our AI Sales Agents close that gap automatically: they follow up with every new lead within seconds of inquiry, run multi-step nurture sequences across SMS and email, and reactivate past clients who have gone quiet. Every interaction is personalised to the lead, tracked to outcome, and optimised over time. The result is more booked appointments from the same lead volume — without adding sales staff.

The Follow-Up Gap Is Where Revenue Disappears

Research consistently shows that the average sale requires 5 to 8 touchpoints before closing. The average business follows up with a new lead once or twice before giving up. That gap — between how many times businesses follow up and how many times it takes to close — is where revenue disappears. An AI Sales Agent closes that gap automatically, without adding sales staff or changing your team behaviour.

How an AI Sales Agent Works

Our AI Sales Agents handle the entire follow-up and nurture process:

Responds to every new web inquiry within 60 seconds of submission
Sends a personalized initial message via SMS and email simultaneously
Runs a multi-step nurture sequence over 7 to 14 days if the lead does not respond
Qualifies leads by asking key questions about their timeline, budget, and requirements
Books qualified leads directly into your calendar for a discovery call or appointment
Reactivates past clients who have not engaged in 6 to 24 months with targeted campaigns

Reactivation: The Fastest Revenue You Are Not Capturing

Your past client list is your most valuable and underutilized asset. Every business has a database of past clients who have not returned — and most of them have not returned because no one asked them to. Our AI Sales Agent runs systematic reactivation campaigns that re-engage past clients with personalized messages, seasonal offers, and service reminders. For most businesses, reactivation campaigns generate a measurable revenue increase within 30 days of launch.

Frequently Asked Questions

How does the AI personalize follow-up messages?

The AI personalizes messages using information from the lead inquiry — the service requested, the location, the time of inquiry, and any other information provided. It does not use generic templates. Each message is contextually relevant to the specific inquiry and sounds like it came from your business.

What channels does the AI Sales Agent use?

Our AI Sales Agents primarily use SMS and email, which have the highest response rates for local service businesses. We can also integrate with other channels including Facebook Messenger and WhatsApp depending on your customer base.

Can the AI Sales Agent handle objections?

Yes. The AI is trained to handle common objections — price questions, timing objections, comparison shopping — with responses that move the conversation forward. Complex objections or requests to speak with a human are escalated to your team immediately.

How does reactivation work?

Reactivation campaigns target past clients who have not engaged in a defined period — typically 6 to 24 months. The AI sends a personalized message referencing their previous service, offers a relevant reason to return (seasonal service, new offering, special offer), and books them directly if they respond positively. Campaigns are segmented by service type, recency, and client value.

What CRM systems do you integrate with?

We integrate with most major CRM and scheduling platforms including ServiceTitan, Jobber, HouseCall Pro, Salesforce, HubSpot, and others. If you use a custom system, we can typically integrate via API or Zapier.

How quickly do AI Sales Agents show results?

Most businesses see measurable improvement in lead conversion within 30 days of deployment. Reactivation campaigns typically generate bookings within the first week. The full impact of the nurture sequence takes 60 to 90 days to measure accurately.

What Clients Say

“The AI sales agent follows up on every estimate request within minutes — even at 10pm on a Saturday. Our close rate on estimates has gone up significantly and I'm not chasing leads anymore. This is the kind of automation that actually pays for itself.”

Google Review

“We were spending money on ads but losing leads because no one was following up fast enough. CastleCS built an intake and follow-up system that qualifies prospects before they ever reach our team. Our conversion from inquiry to consultation has more than doubled.”
