Lead qualification with AI

Every enquiry is scored and classified before it reaches a person, so the sales team spends its time on the ones that can actually close.

The problem

The sales team spends its day on enquiries that were never going to buy.

Most businesses do not have a lead generation problem, they have a lead quality problem, and process automation deals with it in days. Forms filled in out of curiosity, quote requests well outside the profile, emails from people comparing prices with no intention of buying.

Without a filter, the team answers all of it in arrival order, and the enquiries that were worth answering first wait their turn. Some of them do not wait.

The flow

How it works, step by step

01

A lead arrives by form or email

Captured through a webhook or by watching the inbox.

02

The AI reads it and scores it

From 0 to 100 against criteria you define for your business.

03

It classifies cold, warm or hot

And writes a short note explaining the score.

04

Everything is recorded

Every lead is kept, including the ones filtered out.

05

Only the hot ones interrupt

Immediate notification for those, a list for the rest.

Walkthrough

The build in detail

01

Capturing the lead

Leads come from several places: the website form as a webhook, email through a Gmail trigger, WhatsApp. They all land in the same workflow, which is what makes the scoring consistent.

02

Enriching the record

If the lead used a company email, an enrichment API brings back the size, sector and location of the company. This is what separates a real buyer from a name in a form.

03

Scoring

The model receives the criteria of the business, written in plain language, and returns a score plus a justification. The justification matters more than the number: it is what lets you correct the criteria later.

04

Routing

Above 70, the team is notified immediately. Between 40 and 70, the lead goes to a nurture list. Below 40, it is archived with an automatic acknowledgement, because a polite answer costs nothing and a silent one costs reputation.

05

Reading the results back

Every lead sits in a sheet with date, source, score and outcome. After a few weeks that table tells you which channel is worth the money, which is the part most businesses never get to see.
