Our Story

When we started out in 2003, one of our first clients was an urgent care provider. We helped them to make sure that whenever a patient needed them, their vital call got through. This principle has remained core to what we do. We focus on making vital connections, whether that’s a patient needing medical advice, a traveller stuck at an airport, or someone reaching out to a voluntary organisation for help.

How We Think

We’re problem solvers – it’s hardwired into our DNA.

In many organisations, communication has become far too complicated, often to the detriment of the customer experience and the ease at which things get done. We love fixing this. We look at every angle, often finding ways of working that you hadn’t even thought of, or didn’t even know were possible.

It’s just the way we think.

Our Clients

Our clients range from major global brands through to local GP practices. The one thing they all have in common is the need to be there and respond quickly when people need them.

We have a strong heritage in sectors where communications is vital, in particular healthcare, travel and the voluntary sector. Yet we find our solutions offer something unique to any organisation offering time-sensitive customer service.

What They Say

Sesui are proud to have received our ISO/IEC 27001 Information Security Management certification following a comprehensive audit from the leading organisation in the field, BSI.

With telephone donations increasing year-on-year, it was important our contact centre solution could adapt and grow alongside the St Martin-in-the-Fields Christmas Appeal. Sesui provides us with a high level of insight from the call data, and the team works with us to refine the process for next time.

Eight years ago Sesui became one of the stakeholders in our vision for the future, and we made the decision to put our phone system in the cloud. Back then the cloud was a Silicon Valley buzzword and not particularly ‘NHS’. But we did it and very quickly saw results.

When an OHES Environmental customer needs to contact us, it’s critical that they get through. Sesui supplies a level of reliability that means customers can call us and we can immediately meet their needs.

“Our customers don’t care where the team is based. All they want to know is that we’re committed to supporting all of our European territories. And thanks to the Sesui Virtual Contact Centre, we’re able to give our customers the service they expect, in their own language.”

We’re one of just a handful of approved communications providers on Practice Index, set up to help practice managers find the very best partners for their organisation.
