<h2>Who we are, what we do</h2>Sensat is a geospatial AI business that powers advanced and highly functional digital twins for the world's most critical infrastructure projects. We partner with the world's largest construction, engineering and critical infrastructure companies, including National Grid, Network Rail, Heathrow and Severn Trent Water.

Our AI-powered digital twins help teams digitally visualise, plan and manage projects, providing Project Confidence Through Clarity.We are a high trust, high impact team, who offer purpose driven work. We operate with autonomy and flexibility in an agile, flat structure. We look for highly talented, adaptable and curious individuals who love solving meaningful problems and who share our resilient team spirit when facing challenges!We more than doubled ARR in 2025, with a strong pipeline that positions us for another year of 100%+ ARR growth this year!
