Our Story

We’re just getting started

Sentai provides a low cost yet high impact digital care companion – bringing peace of mind to carers and those they care for. Our aim is to support the UK’s 5 million informal carers, with the ultimate goal of helping a billion people around the world.

Founded in 2020, Sentai was founded by UK tech innovator and entrepreneur, Phil Marshman – with the idea forming after witnessing his father’s loneliness during pandemic lockdowns. With more than 30 years’ experience in product development, connectivity and remote technologies, Phil knew that innovation offered a better way to ensure the safety, health and wellbeing of older, independently living adults.
