Julien Lavigne du Cadet

As a CTO with extensive experience scaling tech teams and products, I’ve driven growth from zero to 9 figures ARR. I’ve built exceptional engineering teams from the ground up, co-developed product strategies, and prioritized developer experience to foster innovation and productivity. My expertise spans high-scalability systems, distributed architectures, and advanced data processing, with a strong focus on security and collaboration with data science and machine learning teams. With a keen business acumen, I bridge the gap between technical execution and strategic goals, delivering end-to-end products, web and mobile apps used by millions, and internal platforms that drive both technical and commercial success. I helped establish ZOE as one of the UK’s most known scale-ups and a leader in #techforgood through our impactful work on the Covid Symptom Study and cutting-edge nutrition research.
