From Missed Leads to Maximized Opportunities: CST’s Transformation Story
When Cursos de Soldadura CST reached out to us, it was clear they were facing a significant challenge. They were losing leads and missWith a limited team unable to handle the volume of leads, CST urgently needed a solution. That’s where Peepz came in.
The Challenge: CST’s Growth Pains
CST, a school specializing in welding courses, was beginning to feel the growing pains of success. The number of leads was increasing, but their ability to follow up and qualify those leads wasn’t keeping pace. More than 50% of qualified leads weren’t receiving proper follow-up. Hiring a sales team at this stage wasn’t a viable option for the company.
The Core Issues
Leads weren’t being followed up on in time, leading to missed opportunities.
As a result, the brand’s reputation was taking a hit.
There were no defined criteria for lead qualification.
Interactions were happening across multiple channels (an outdated chatbot, WhatsApp, social media) without any proper integration.
Consequently, valuable leads were slipping through the cracks, with no classification or adequate follow-up.
The Solution: An AI-Powered Lead Capture and Qualification Agent
After a thorough analysis of CST’s marketing and sales funnel, our first step was to create a FAQ + Lead Capture AI Agent.

Multi-Channel Integration: The AI Agent was integrated with CST’s existing channels (WhatsApp, social media, and the chatbot).
Automated FAQ Responses: The agent was trained to automatically respond to common questions from potential students, ensuring every inquiry received a prompt reply.
Lead Qualification: We worked with CST to establish clear criteria for qualifying leads as either “qualified” or “unqualified.” This allowed the AI Agent to identify the most promising prospects.
Technologies Used
The success of this solution relied on a combination of key technologies:
OpenAI API: The GPT-4o-mini model, which after testing, proved to be a perfect fit for CST’s needs.
AWS: We used AWS infrastructure to host and run the AI Agents, ensuring stability and scalability.
Airtable: Airtable was selected as CST’s CRM, where all leads were integrated for efficient and organized follow-up.
Make.com: This tool served as the middleware for executing some of the automations.
Calendly: Calendly was used to schedule in-person visits to the school.
Impact and Results: What Changed for CST
With this solution in place, CST achieved:
Increased Response Rate: Every lead now receives a real-time response, eliminating the need for a human to handle simple queries.
Improved Lead Qualification: CST now has a streamlined process to identify which leads are worth pursuing, enhancing the effectiveness of their campaigns.
Process Automation: By automating the invitation process for school visits, CST now provides a more personalized and efficient experience.
Conclusion: A Step Forward in Digital Transformation
