Quantum Acquires Cashback & Custard: Strategic Expansion into Digital Rewards
Performance marketing group Quantum has announced the official acquisition of two prominent consumer reward brands from customer acquisition firm Submission Technology. The transaction covers the well-established UK rewards portal Cashback.co.uk, the fast-growing gifting platform JoinCustard.co.uk, and the dedicated Custard mobile application. The entire asset transfer is scheduled to formally complete on 1 July 2026.
The takeover represents Quantum’s inaugural entry into the direct-to-consumer cashback and digital rewards sector. By integrating these consumer-facing applications, the company is diversifying its operational footprint beyond its core affiliate marketing roots and moving directly into proprietary consumer value products. The acquisition is positioned as a extension of Quantum’s data-led, performance-first business model, folding in two scalable platforms alongside the specialist technical infrastructure needed to drive them.
Global Infrastructure and Tech Integration Mechanics
The purchase of these digital assets follows a period of rapid international growth for Quantum. Backed by a 36% year-on-year revenue increase in 2025, the company has recently scaled its services into Ireland, South Africa, and multiple jurisdictions across the United States. Managing this expanding cross-border network across the UK, US, Ireland, and South Africa supports Quantum’s long-term corporate roadmap to become the global market leader in digital comparison services.
To optimize and scale the incoming consumer platforms, Quantum will migrate both assets onto its proprietary technology infrastructure, the Qi Platform. This centralized intelligence engine will allow the company’s technical teams to accelerate product updates, deliver precise user personalization, and extract deeper behavioral analytics. The transition will be managed by Quantum’s in-house engineering group, deploying dedicated data engineering, software development, and machine learning capabilities to oversee the backend integration.
Executive Insight on Scalability and Transition
Jamie Walters, Chief Executive Officer and Co-Founder of Quantum, highlighted the commercial rationale behind entering the consumer rewards arena:
“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.”
Neil Durrant, Chief Executive Officer of Submission Technology, expressed confidence in Quantum’s operational capacity to introduce the platforms to broader audiences:
“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.”
Technical Analysis: The Data Arbitrage of Merging Affiliate Streams with Direct Consumer Loyalty
From a technical performance marketing perspective, Quantum’s acquisition of Cashback and Custard signals a sophisticated shift away from traditional, volatile affiliate traffic models toward high-retention consumer ownership. In standard affiliate setups, a comparison platform must continuously reinvest capital to re-acquire the same users through paid search or social media marketing channels. This create a permanent reliance on third-party ad networks and drives up customer acquisition costs.
By acquiring established cashback and gifting platforms, an operator successfully changes its user mechanics. Cashback and digital rewards platforms boast incredibly sticky user loops because consumers are financially incentivized to routinely check back in before completing any online transaction.
When these high-frequency consumer touchpoints are channeled through a proprietary intelligence stack like the Qi Platform, it unlocks immense data arbitrage opportunities. Quantum’s internal machine learning engines can track specific purchase patterns across the rewards platforms and instantly use those insights to deliver highly relevant, real-time comparisons in its other business verticals, such as financial products, insurance, or utility services.
By integrating these data streams at the core database level, Quantum converts simple transaction rewards into a cross-selling engine. This setup lowers long-term acquisition costs, increases user lifetime value, and protects its traffic pipeline from shifting web search algorithms.
