'Small but mighty' is a phrase that fits Manchester-HQ Sync well, especially in a year where the Apple partner jumped 11 places in the ranking.

Sync supports organisations across the UK, providing services around adoption, deployment and management of Apple.

This includes the provision of hardware, software and finance solutions, as well as installations, training, technical support, repairs, and more.

The Apple consultancy is focused on the educational sector.

"If you have a vision, we make it a reality with technology. We have a hugely talented group of people, loyal clients, trusted partners and a commitment to make a difference," CEO Chris Costello commented for CRN.
