Senior🎓
Top SchoolJoachim Valente is a tech founder and seasoned engineering leader with 12+ years of experience across Google, Stripe, and Neon, currently based in San Francisco. He specializes in fraud, risk, and security intelligence, having led cross-functional teams that blend engineering, data science, and strategy to protect large-scale digital banking and payments platforms. His background in computer vision (UCLA) and engineering (CentraleSupélec) underpins a strong ML-first approach to product problems, from ranking systems at Google to reinforcement learning and model-driven actioning at Stripe. Joachim combines operator-level product impact with startup grit—founding Quis Contacts and a stealth startup while shipping mobile features and open-source tracking libraries earlier in his career. An avid pianist and world traveler, he brings creative curiosity and global perspective to technical leadership and product design. Notably, he has moved quickly between high-impact roles, scaling teams and systems that materially reduce fraud losses for major financial platforms.
