Our Story 

Founded in 2017 by Emily Kent, Barnaby Kent, Ian Packer and Sam Low, One Big Circle started with a vision to transform how critical national infrastructure is maintained and monitored. Today, our home next to Bristol Temple Meads is where more than 60 talented professionals collaborate to deliver intelligent video solutions that make a real difference. Our flagship product, AIVR (Automated Intelligent Video Review) is widely deployed across the UK network, and other territories, capturing high-definition imagery and data, enabling remote inspection, supporting safer and smoother railway operations.

What Drives Us

Our mission is to empower our clients and partners with technology that improves safety, efficiency, and insight across the rail industry and beyond. But we know that our impact is only as strong as the culture we bring together. That’s why we invest in our people – providing opportunities for growth and encouraging curiosity.

Our Culture: The Circle Theory

At One Big Circle, our name is the foundation of how we work. Our ‘Circle Theory’ means we see teams as not isolated departments, but as interconnected circles that overlap, collaborate, and learn from one another. This approach encourages curiosity, open communication, and cross-functional teamwork, making our way or working both dynamic and rewarding.

We believe the best workplaces are built on trust, collaboration, and a shared sense of purpose. Our values, aptitude, expertise, creativity, leadership and community, influence every decision and interaction. By nurturing an environment where real teamwork flourishes, we’ve created a workplace that’s vibrant, supportive, and motivating – a place where people genuinely enjoy coming to work each day.
