Today an assistant answers them, and sells too. How Latin America's leading EdTech platform opened a WhatsApp sales channel that didn't exist before, and now runs pre-sales, student self-service, and staff support on StudioChat. COVERAGE One assistant across Spanish-speaking LATAM \>80% Deflection rate 100% Conversations answered instantly 5% Inquiry-to-sale conversion (WhatsApp) 20+ Countries served "StudioChat became our best salesperson. Available 24/7, knows every course inside out, and the ROI was immediate." C Christian Patiño Founder & CEO, Coderhouse [](https://www.linkedin.com/in/christian-alberto-patino/) The Challenge ## A branch system that couldn't scale Coderhouse had a complex decision-tree chatbot that was impossible to maintain. Every new course, price change, or promotion meant hours of manual updates across hundreds of branches. Worse, leadership had zero visibility into what customers were asking. ### Impossible to maintain 200+ courses, 20+ countries, constant price updates. The branch system couldn't keep up. ### Zero visibility Leadership had no insight into customer questions, trending courses, or conversion blockers. ### Lost sales opportunities Rigid flows couldn't adapt to individual needs. Potential leads dropped off frustrated. The Solution ## An AI Sales Assistant that actually sells StudioChat built a custom AI assistant deployed across Coderhouse's entire website via WhatsApp. Its mission: understand each prospect's needs and guide them to the perfect course. ### Intelligent Course Matching Scenarios that guide users based on their goals. 'I want to improve my business skills' triggers personalized career path recommendations. ### Multi-Country Pricing Real-time pricing by country. Automatically shows the right currency and local payment options for Argentina, Mexico, Colombia, Spain, and 15+ more. ### Direct Enrollment Links When the assistant convinces a prospect, it provides direct enrollment links. No friction, no hand-offs. ### Payment Support Complete knowledge base for payments: methods, installment plans, country-specific rules. Resolves payment questions instantly. ### Spam Detection Built-in spam filtering keeps the team focused on real prospects while the assistant handles the noise. ### Student Support Beyond sales, the assistant also handles existing student inquiries, contributing to the 80%+ deflection rate. CONVERSATIONAL COVERAGE ## An edtech's entire conversational stack, in one place. What started as a sales channel now covers three distinct fronts (pre-sales, student self-service, and staff support), each trained on the judgment of the team that already handled it. ### Pre-sales: bot "Sofía" A fully self-managed WhatsApp sales channel that didn't exist before. * 100% of conversations answered instantly * 5% conversion over the last 30 days (vs. \~3% historical) * 80%+ autonomous resolution * \~85% CSAT ### Student self-service Course changes, commission changes, Zoom links, and login, resolved without a human. * \>50% deflection * 630 commission changes in 30 days * 2,500+ since launch ### Staff support Tutors and teachers resolve grading and payout questions through the same channel. * Channel just activated * 30+ refunds and credits already processed Results ## A true sales machine The numbers speak for themselves. StudioChat transformed Coderhouse's WhatsApp channel from a support burden into their most efficient sales channel. ### Inquiry-to-sale conversion On the WhatsApp channel, conversion rose from a \~3% historical average to 5% over the last 30 days. 5% conversion (WhatsApp) ### Instant attention No inquiry waits in a queue, regardless of the hour or the country. 100% of conversations answered instantly ### Deflection Rate The vast majority of inquiries are resolved without human escalation, including both sales and support. \>80% autonomous resolution ### Executive Visibility Real-time dashboards showing most searched courses, frequent questions, and conversion patterns. Data-driven decision making ### Proactive Alerts Automatic detection and alerts when payment platform issues occur, enabling rapid response. Real-time error detection ### Global Reach One assistant serving all of Latin America, the USA, and select European markets in multiple languages. 20+ countries, seamless experience "We went from a rigid branch system that was a nightmare to maintain to an intelligent sales assistant that actually understands our leads. It's not just answering questions: it's closing deals. The visibility it gives us into what our prospects are asking for is invaluable for product decisions."
