Why We Exist

At Raylo, we’re on a mission to accelerate the move to a circular economy. The only way customers and manufacturers will make that shift is if it’s simple and cost-effective - this is where we come in. We’re building a category-defining global subscription infrastructure, making premium tech accessible and affordable for both consumers and businesses. With over 180,000 subscribers in the UK and growth accelerating - we’ve proven the demand for a smarter, more sustainable way to access technology.

Raylo is a fast-growing and profitable company, backed by global investors including Macquarie, Nat West, and Channel 4 Ventures.

We are proud to have been selected for Endeavor’s network in 2024, underscoring our role as a high-impact, mission-driven business with global ambitions. And in 2025 we were recognised as part of Tech Nation’s UK’s Future Fifty programme.

We have been B-Corp certified since 2021 and were recently acknowledged by S&P Global for the positive impact of our circular business model via a Green Financing with Nat West.

At Raylo, performance matters. We set ambitious goals, move fast, and hold ourselves to a high standard, because our mission is too important to settle for less.
