Two AI agents replacing manual lead routing and review collection for a Portuguese home-solutions group.

How we built two AI agents — one for lead routing, one for post-service reputation — integrated into HubSpot, Outlook, WhatsApp, and Google Sheets, removing process dependencies on individual availability and enabling scale across European HORECA markets.

01 / Client
A leading Portuguese home-solutions group serving HORECA markets across Europe.

Lead volume was scaling. Manual routing wasn't.

Grupo Filtrarte is a leading Portuguese company in home solutions, specialising in air and water purification and wellness products. Its portfolio comprises numerous brands serving the national HORECA sector across various European markets, with over 30 years of experience and 200,000+ customers.

As digital campaigns scaled, lead volume grew steadily. The challenge was to ensure that each lead reached the right distributor, at the right time, with all the information needed to take action. The high volume of manual lead-management work resulted in errors, high operational cost, and an inability to scale without expanding the team.

02 / Challenge
Two critical processes — lead routing and review collection — depended entirely on people.

Two workflows that scaled with team headcount, not business volume.

Both processes were plagued by friction, inconsistency, and operational risk. Without automation, the operation could not grow without proportionally growing the team — economics that don't work in distribution.

01

Lead Referral

Every lead captured had to be analysed manually — which advert did it come from, which geographical area? Only this information made it possible to direct the lead to the correct distributor. Without automation, the process was slow, dependent on availability, and prone to routing errors.

02

Review Requests

Review requests relied on a specific person to identify which customers had been served and to submit the request manually. The process came to a standstill when that person was unavailable.

03 / Approach
Two AI agents, integrated into the existing stack — no new tools required.

Two agents. Two streams. Autonomous operation.

Post-service reputation

Agent Review — automated review collection across channels

Detects when a customer support session has been completed in HubSpot, filters customers who have not yet received a feedback request, sends automatic review requests by email via Outlook and via WhatsApp using the API, and records submissions in Google Sheets to avoid duplicate entries.

Lead capture & routing

Leads Agent — capture, qualify, and forward

Identifies new leads from Meta and Google Ads campaigns, checks Google Sheets every 15 minutes, deduplicates against existing records, identifies the advert and geographical location, creates the contact in HubSpot, and notifies the internal contact person with all information needed to forward to the correct distributor — then marks the lead as processed.

Correct routing of every lead

The agent identifies the source advertisement and the location. The person in charge receives the correct information to direct the lead to the right distributor — every time, regardless of who is on shift.

Faster, more consistent response

Checks are carried out every 15 minutes regardless of who is available on the team. No bottleneck, no leads sitting in inboxes overnight.

Automated reminders without staff dependency

Review requests are sent at the right time, via email and WhatsApp, without relying on the availability of any specific person.

Scaling without team growth

Lead volume can grow — across Portugal and European markets — without creating additional operational pressure or requiring more headcount.

06 / In the team's words
"
The agent does not replace the process — it requires the process to be properly set up. When the right conditions are in place, scaling happens naturally. Otherwise, it merely automates chaos.

07 / Stack
Mature, auditable, regulated-environment-ready.

Technology stack.

We integrated into the existing stack — HubSpot, Google Sheets, Outlook, and WhatsApp — instead of replacing it. With no new tools required, the team adopted the agents immediately and the process maintenance stayed within the client's existing operational ownership.
