Salary benchmarks
Our take
As a society, a disposable tech culture has developed, which is both expensive and harmful to the environment. Raylo is offering a more sustainable alternative. Through its subscription platform, consumers and Small to medium-sized businesses can subscribe to new and refurbished devices like phones, tablets and laptops, paying a monthly fee for the length of the contract.
Raylo sets itself apart through affordable device subscriptions, with the option of flexible upgrades. The environmental and economic benefits of device lifecycle extensions are significant, as, despite consumers’ increasing reliance on electronic devices, research from Ofcom indicated that many consumers struggle with the affordability of mobile phones. Raylo's circularity is also an essential part of the move towards more sustainable production practices and the reduction of tech waste.
In 2022, Raylo cemented its status as an actor for good with its recognition as a B-Corporation. The company has also netted considerable funds, which will enable it to expand operations, with plans to grow its direct-to-consumer channel, as well as an expansion of its embedded subscription integrations with some of the world's leading device brands.
