Lead-Conversion & Sales Follow-Up AI Agent

Answer inbound enquiries, book tours and trials, and follow up only where the consent record allows it — then hand the lead to the named sales rep, who decides what is sold.

What this agent does

Automates the reply, not the permission

In
01

Ingesting enquiries, consent records and provenance from supported CRM, phone and messaging channels.

02

Normalising channel identifiers and consent wording, and carrying each forward with its source.

Reason
03

Answering inbound enquiries from the timetable, the pricing card and club information.

04

Treating any AI voice call as an artificial-voice call that consent governs.

05

Checking where each lead's consent came from, and suppressing outreach it cannot support.

Decide
06

Flagging any consent record that is missing, stale or revoked in channel.

07

Routing each enquiry to the named sales rep for handover.

Out
08

Retaining the consent relied on, the message sent, the opt-out and the handover per lead.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent answers and books; the named sales rep decides what is sold, and the operator stays responsible for the consent.

Example workflow

One enquiry, arrival to handover

AgentHuman
1Enquiry receivedWeb form, class-booking page, phone call, text or social message
2Consent checkedSource, wording and date of the consent on record, and any revocation in any channel
3Reply preparedAnswer, tour and trial options, flagged lines and confidence
4Controls appliedConsent-record checks, DNC and suppression scrubs, local-time windows, frequency caps and confidence threshold
No human action required

Stages 1 to 4 run unaided, and no outbound contact is made at any of them — the agent is answering, and the rep's lane opens at the confidence gate.

5DecisionBranches at the confidence threshold
High confidence

Goes to the named sales rep to take over.

Low confidence

Adds a consent review first.

Sales handover

The lead is held with its consent record, its flagged lines and the confidence.

Accept · Amend · Send to consent review
Accepted — the rep has the lead
6Sales systems updatedOnly where write access and approval policy allow it
7Outcome evaluatedReply accuracy, opt-out handling, consent exceptions and corrections made after sending
Amendments

Each rep amendment is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items
Outbound contact where no consent record exists.
Contacting a lead who has revoked, in any channel.
Quoting a price or term not on the published card.
Enrolling a lead in a membership or a recurring charge.
Automation boundaryAgent acts unaided
Reply to an inbound enquiry from the club's published information.
Book a tour or a trial visit in the slots held open.
Answer documented questions on hours, classes and kit.
Check the consent record before any outbound step, and hold the rest.
Any outbound step runs inside the boundaries agreed at implementation, behind the consent record.
AI-voice calls without documented written consent.
Treating a purchased lead's consent as verified.
Serving statutory contract or health-club notices.
Changes to consent, window or handover rules.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every enquiryFrom the enquiry channel
03Response

Reply from the record

Draw on the club's published information and the consent captured with the enquiry.

01Approved path

Answer fast, inside the consent

Routine questions about hours, classes and tours are answered as they arrive.

02Human review

Stop where the consent stops

Missing, stale or revoked consent suppresses the outreach and puts the lead in front of a rep instead.

04Build an evidence trail

The enquiry, the consent record it relied on and the rep who took it over stay together.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls

Six layers between the model and the lead

Each layer contains the next. What gets past the set is listed in the map below.

How Nestack evaluates it

Evaluate the follow-up workflow — not only the reply that went out.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the message the lead receives
Depth of coverage ▼
E1Final-output evaluationDid the reply answer what was asked, from documented information?
E2Step-level evaluationDid the agent read the right lead, the right consent and the right rules?
E3Tool evaluationDid an opt-out suppress the lead in the channel it arrived on?
E4Confidence calibrationDo low-confidence replies actually attract more rep amendments?
E5Slice evaluationHow does performance change across specific lead sources?
E6Business outcomeHow many replies needed a rep amendment or a correction after sending?

Failure modes

Where each failure originates in the agent

Seven failure modes, each placed where it first appears.

Agent lifecycleDirection of processing →
01 · Retrieval1 mode
LM-03

Superseded consent read

The consent returned is older than the lead's opt-out.

Vacatur read as consent

A removed restriction is read as a removed consent requirement.

A revocation is queued as though the duty were not yet in force.

Affected slices

Overall response quality can hide one lead source

Break the amendment rate down by lead source before you read it in total. Over every enquiry it looks small; concentrated in the sources whose provenance is thinnest, it does not.

Evidence-linked improvement

Each cycle ends with one more case

Nothing closes because it was understood. It closes when the next release has to pass a case, and that suite is what the next reply out is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Amendments and post-send corrections rise in one lead source.

02Diagnose

If the consent record was wrong, the reply was wrong before it was written — so both are read.

03Improve

Changes ship against a version with the conversations that caused them.

04Verify

A failing case blocks release until it clears.

05Learn

The case is permanent, and the outreach rules move with it.

Learn → DetectThe return edge. The next detection is measured against the longer suite.

Typical build scope

Twelve workstreams across six weeks

Build a lead-conversion agent around the consent you already hold.

Show us your enquiry channels and who takes a lead over. If you can show us where each lead's consent came from, we'll map the follow-up, set the automation boundary and name what stays with the rep.
