Rockstar🎓
Top SchoolCarlos Fenollosa is a Barcelona-based AI professor, entrepreneur and engineer with 13 years of experience building production AI and Big Data systems and founding multiple startups. He founded Puput, an early multimodal chatbot, and Optimus Price, a pricing-optimization platform used by clients like Nestlé and eBay that delivered double-digit profit uplifts and millions saved in stock losses. Academically rooted in computer engineering and AI, he spent years as a doctoral researcher at the Barcelona Supercomputing Center and holds a patent for applied AI work. Carlos combines hands-on low-level programming (his OS-from-scratch tutorial is one of the top C projects on GitHub) with product and team leadership, having raised several million euros and led a 20-person team. An active communicator and author—his 2024 popular science book La singularidad and widely read online essays reach millions—he also collaborated on an analytics project with Microsoft, underlining his ability to bridge research, industry and public discourse.
