Matias Hoyl
Product Data Scientist
I'm a data scientist and machine learning engineer passionate about using AI to create impactful digital products. My background includes working with edtech startups, big tech companies, and social enterprises, always focused on using technology to solve real-world problems. I've co-founded ventures using large language models and adaptive learning systems to build educational tools like reading platforms for kids and adaptive assessments for schools.
I've also worked at Meta and other leading companies, contributing to generative AI products, data analysis, and user-focused machine learning models. I love combining my skills in data science, product management, and engineering to bring ideas to life—whether that's making AI-generated stories more engaging or building platforms that help people learn and grow. Outside of work, you'll find me enjoying the outdoors, playing music, or writing about AI.
Experience
ML Engineer Intern
