Quantum adds Cashback and Custard to growing digital rewards portfolio.

Quantum adds Cashback and Custard to growing digital rewards portfolio. July 1, 2026 Quantum International Holdings has officially expanded its portfolio beyond affiliate marketing, announcing today, July 1, 2026, the acquisition of digital rewards brands Cashback.co.uk and JoinCustard.co.uk. Cashback.co.uk is a well-established UK cashback platform with hundreds of thousands of loyal customers. JoinCustard.co.uk, launched in October 2024, is a fast-growing digital rewards and gifting platform, while the Custard mobile app extends the platform's reach to users on the go. The acquisition marks Quantum's first move into the digital rewards and cashback market, expanding its footprint beyond affiliate marketing and into direct consumer reward products. It is a natural extension of Quantum's data-led, performance-first model, bringing two complementary consumer platforms into the business alongside the technology and expertise needed to scale them. The deal builds on Quantum's momentum following 36% year-on-year revenue growth in 2025 and recent launches in Ireland, South Africa and multiple US states. With operations now spanning the UK, US, Ireland and South Africa, Quantum is accelerating its ambition to become the world's most used digital comparison service. Jamie Walters, CEO of Quantum International Holdings, said:"Cashback and Custard are proven platforms with loyal users, clear product-market fit, and strong commercial potential. What they need now is scale, and that is where Quantum can add real value. We have the data, technology, and performance mindset to grow these platforms quickly and responsibly. This is a bold move into a fast-growing consumer rewards space, and a natural next step in our ambition to connect more people with better value across the digital economy." Quantum's proprietary technology stack and intelligence engine, Qi Platform, will support growth across the acquired assets by enabling faster product iteration, improved personalisation, and deeper insight into user behaviour. Quantum's in-house technology team of dedicated data engineering, machine learning and software engineering capability, will support the integration and development of both platforms. Neil Durrant, CEO of Submission Technology, added: "We built Cashback and Custard from the ground up, and we are incredibly proud of what the team has achieved. Quantum is the right home for these platforms. Their technology, commercial relationships and ambition make them well placed to take Cashback and Custard to a much bigger audience. It is an exciting next chapter for both businesses." The financial terms of the transaction have not been disclosed.
