Otta's take on Sensat

Sam Franklin headshot
Sam Franklin
CEO of Otta

Sensat create digital twins, or digital representations of real world locations, to help users better understand the physical world. The company chose to target the construction industry as this is historically one of the least innovative sectors that has seen minimal advances in technology.

However, the company has received interest from other organisations, and it's likely that there are many possible applications yet to be considered. Sensat's success is also clear: it was the first company in the UK licensed to fly autonomous drones Beyond Visual Line of Sight (up to 200 kilometres away) over major motorways due to their technology's central use in over £10.5bn in major infrastructure builds.

The company's product is ahead of the curve in construction-focused digital twin technology and its recent funding means that it is looking to aggressively scale, delivering increases in productivity to an industry that is notoriously antiquated.

The panel's take on Sensat

Gerard Grech headshot
Gerard Grech
CEO of Tech Nation

Sensat is transforming infrastructure construction, using artificial intelligence and a broad array of data sets to create digital representations, or digital twins, of real world locations, allowing companies operating in this space to make more informed decisions remotely. Sensat’s offer has come to the fore in the post-Covid era, providing digital workarounds when physical interactions and travel aren’t possible.

Today, infrastructure is still one of the least digitised sectors in the economy, resulting in a reliance on traditional and inefficient ways of doing business. But the fallout from Covid-19 is accelerating the adoption of technology in traditional industries across the economy as companies seek to optimise their processes, bring down costs, and build more resilient solutions to allow for day-today business to carry on as usual. Their clients already include Heathrow, Network Rail and National Grid.
