James Kellerman

Senior Leadership Team

James is our Chief Technical Officer, bringing two decades of tech leadership experience to ieso. He crafts our technology strategy, oversees the building of strong product and engineering teams, and drives the delivery of stellar products and platforms.

Before ieso James led teams across Healthtech, Automotive and Defencetech – and his former clients include the US Department of Defence.

As Touch Surgery’s VP of Engineering, he led multiple departments in training cutting-edge machine learning networks. These were able to recognise surgical tasks, predict duration, and improve the performance of surgical teams.

As CTO of Tempus Energy, he headed up a team of data scientists and engineers building machine learning systems that helped energy customers reduce costs and emissions.

“For me a key part of my job is painting a picture of what the problem is then giving team members the tools and resources to go and create the solution themselves. If they understand what you're trying to create and why, you get all the quality that person can bring through their creativity, insight, and capabilities.”
