Colégio Cognos increases scheduled visits by 150% and reduces the service queue by 50% with AgentFlow on WhatsApp

Education with strong values and operational efficiency

Founded in 2012, Colégio Cognos is an educational institution grounded in Christian principles and values, offering complete basic education from nursery through high school.

With over 14 years of history, the school adopts the Mackenzie Education System, bilingual English instruction, and Robotics, while prioritizing holistic, human-centered, and high-quality education.

However, as the volume of inbound inquiries grew, customer service gradually became a bottleneck — especially during peak periods such as enrollment seasons and school events.

The challenge: making automation more natural and continuous

Before SleekFlow, Colégio Cognos had already worked with several automated customer service providers. The problem?

Most bots relied on rigid menus, felt unnatural, and conversations often ended as soon as tuition pricing was shared. Even more recent AI-based solutions lacked proper training capabilities and failed to deliver truly fluid interactions.

Additionally, the team faced:

• Overly complex flow editors that made updates impractical

• Inefficient follow-up processes

• Dependence on an external CRM that didn’t work well

• A small team not fully dedicated to customer service

The result was clear: lost conversations, long queues, and enrollments that failed to move forward.

The turning point: AI trained for the school’s real needs

What led Colégio Cognos to SleekFlow was simple and decisive: the ability to train AI according to its real operational needs.

From day one, implementation was fast and intuitive. With just a few adjustments, the AI agent was already handling conversations, answering questions, and guiding interactions naturally.

The implementation of the service agent was absolutely simple. After training, it was already handling interactions!

The solution in action: AI that chats, schedules, and follows up autonomously

Today, SleekFlow’s AI is used continuously in Colégio Cognos’ customer service operations and goes far beyond answering questions.

Automatic visit scheduling

The AI began scheduling visits, guiding conversations all the way to confirmed appointments, always within the school’s operating hours.

It was a surprise for us. The AI talks naturally and has already scheduled several visits on its own.

Event automation with Google Sheets integration

During events, field trips, and graduation ceremonies, the team used to face an overwhelming volume of repetitive questions.

The solution was simple yet powerful: automation integrated with Google Sheets.

By sending hashtags such as #graduation, #fieldtrip, or #literaryfair, the system:

• Retrieves the correct information from the spreadsheet

• Returns real-time event status updates

Result: a 90% reduction in the workload of service agents on event days.

Guaranteed follow-up with a “mini CRM”

Using the Lists feature, Colégio Cognos built its own “mini CRM.”

This ensured that all our contacts received proper follow-up.

Instead of merely notifying an agent, SleekFlow:

• Automatically reopens conversations

• Applies customized rules and parameters

• Ensures no contact is left without a response

The differentiator: a simple, powerful, and unlimited flow builder

For the Colégio Cognos team, SleekFlow’s biggest differentiator is the Flow Builder chatbot tool.

According to João, the only limitation is your imagination.

With just a few clicks, it’s possible to:

• Update contacts

• Integrate spreadsheets

• Send automated messages

• Create internal alerts

• Modify queues

• Apply segmentation labels

• Automate end-to-end processes

All of this in a simple, visual, and objective way — without relying on technical teams.

AI without losing the human touch

Was there concern about losing human connection in customer service? Yes.
But in practice, the opposite happened.

The AI is so human that many people think they’re talking to a real person.

The AI starts, manages, and concludes conversations autonomously. When needed, the human team steps in seamlessly — without friction or customer complaints.

Results that truly matter

Since adopting SleekFlow, the impact has been clear:

• +150% increase in confirmed visits via WhatsApp

• –50% reduction in the service queue

• No more customers waiting over 24 hours for a response

• 100% of contacts receiving effective follow-up

The team gained organization, predictability, and time to focus on what truly matters.
