Barcelona: AI Business Transformation — a 4-hour hands-on workshop designed to elevate you from tool-user to system-builder. This intense session targets practical frameworks for selecting, integrating, and scaling AI across marketing, sales, and operations. The program converges on a three-stage evolution (Standard, Expert, Professional) and delivers a concrete playbook you can deploy in your business from Day 1. If you’ve ever felt overwhelmed by a flood of AI tools, this workshop helps you move beyond tool-chasing to architecting an end-to-end AI-enabled workflow. What you’ll do and learn: - The Art of Selection: Establish Marketing Selection Logic for choosing between large language models (LLMs) like ChatGPT, Gemini, and Claude based on your brand voice, plus how to weave Freepik into a cohesive content workflow. See and compare strengths, trade-offs, and integration points. - Sales Architecture: Define when to deploy autonomous voice agents versus chatbots, and evaluate stacks including GHL (GoHighLevel), ElevenLabs, Vapi, and Apify to optimize lead generation and conversion. - Operational Workflows: Learn how to use n8n as the central nervous system to link disparate tools into a self-operating business engine with minimal manual handoffs. - Infrastructure Thresholds: Build a decision matrix for data security and deployment models, including cloud APIs vs local models hosted on a VPS or high-performance setup (Antigravity reference) for sensitive data.
