Sued Three Times for Cold Email in Germany, He Pivoted to AI Agents and Hit Zero Churn | Daniel Quiroga @ PUNKU.AI
Daniel Quiroga built an AI SDR startup on cold email, got sued three times in Germany, and watched the entire outbound playbook collapse under new anti-spam rules. He pivoted to AI agents for tour operators and museums, priced it with a money-back guarantee, and hasn't lost a single customer since. This conversation is about what happens when the market pulls you somewhere you didn't plan to go, why a 63-year-old castle owner in Italy became one of his most active users despite a complete language barrier, and how staying monthly-only on purpose taught him more about retention than any annual contract ever could. In this episode: → Why cold email became legally and technically unworkable in Germany, and what killed the AI SDR pitch → The customer request that pulled PUNKU.AI from AI SDR into AI agents for tourism and entertainment → Why Daniel priced PUNKU.AI with a money-back guarantee and still hasn't had a single customer churn → The castle owner in Italy who built her own AI agent despite a full language barrier → Why he kept subscriptions monthly-only on purpose, and how customers moved to yearly without discounts → How a co-developed MCP integration and a warm customer referral became PUNKU.AI 's best growth channel For founders mid-pivot, anyone building AI agents on top of legacy software, and anyone who thinks cold outbound still works the way it used to. ----------- Episode's Chapters ----------- 0:00 – Introduction 0:20 – What is PUNKU AI 1:08 – Controversial SaaS Opinions 3:52 – The Origin Story of PUNKU 7:05 – Pivoting Away from AI SDR 12:08 – Zero Churn and Customer Retention 23:00 – Marketing and Partnerships 28:31 – Co-Founders and Final Advice 🎙️ Daniel Quiroga — https://www.linkedin.com/in/daniel-quiroga/ PUNKU AI — https://www.punku.ai/ 👉 Subscribe for weekly conversations with SaaS founders, operators, and acquirers.
