Forefront RF, a Cambridge-based fabless semiconductor startup, has snapped £16 million in Series A funding. The round saw participation from existing investors BGF (which recently invested in Twenty7tec and Kubus) and Foresight Group, alongside new VC partners, Octopus Ventures (which recently backed Semble and Cambri) and Cambridge Innovation Capital.
This investment follows the £3.75 million funding raised last year. The company intends to use the funds to expand operations and its development efforts. The company is set to transition from an early-stage startup to a mature player in RF technology, gearing up for the 2026 launch of its first-generation product, the FFM51010, to the fast-growing cellular-enabled smartwatch market.
Next-gen connectivity solutions
Founded by Dr. Leo Laughlin and Julian Hildersley in 2020, Forefront RF aims to make multi-band smartphones, wearables, and IoT Devices simpler to design and more globally accessible. It empowers mobile device manufacturers to overcome printed circuit board (PCB) size limitations while supporting more frequency bands with simplified, cost-effective designs.
The company’s first solution is aimed cellular-enabled wearables, where every millimetre of PCB is critical and expanding frequency band capabilities is essential. By replacing bulky fixed-frequency filters and duplexers with a self-configuring tunable duplexer, Forefront RF enables devices to dynamically adjust to any required frequency, reducing overall component list and manufacturing complexity. This innovation not only saves valuable PCB space but also minimises variants, reducing waste and enhancing supply chain efficiency.
Since its debut, the company has pushed the boundaries of wireless technology with its patented Foretune technology. It is a transformative self-interference cancellation system that addresses leakage and interference issues inherent in all wireless devices. By inverting and neutralising unwanted signals similar to noise-cancelling headphones, Foretune enables cleaner signal transmission and reception in software-defined radio systems. This helps simplify product design and production processes. With Foretune, Forefront RF is poised to redefine RF standards and drive significant advancements in next-generation wireless technology.
Ronald Wilting, CEO of Forefront RF said: “Securing this Series A funding underscores the strong confidence our investors have in Forefront RF’s vision and market potential. With continued support from Foresight Group and BGF, and new partnerships with Octopus Ventures and Cambridge Innovation Capital, we’re well-positioned to scale rapidly from engineering prototypes to mass production.”
Investors’ views
“Forefront RF has created a solution to one of the greatest bottlenecks in mobile data connectivity, based on a decade of advanced research and development. Cambridge Innovation Capital is delighted to partner with Forefront RF as it prepares to launch its highly differentiated product lines into the growing wearables market. We look forward to supporting the team as they scale to deliver global impact across billions of connected devices,” said Edward Inns of Cambridge Innovation Capital.
Owen Metters, investor at Octopus Ventures, continued; “We’re delighted to be supporting Forefront RF on their journey, and are really excited by the Team’s potential. Their patented technology will revolutionise how mobile devices are designed, reducing complexity, and streamlining supply chains. The continuing proliferation of cellular-enabled devices means there is a significant opportunity for technology such as ForetuneTM.”
Andy Bloxam, Head of FTW at Foresight stated: “We are excited to be making this follow-on investment into Forefront RF, a developer of breakthrough tuneable duplexers that can potentially underpin next-generation RF-enabled devices. This is a testament to Foresight’s long-standing commitment to the Cambridge ecosystem, which is widely recognised as a great place to scale disruptive deep-tech businesses such as Forefront.”
Luke Rajah, investor at BGF, iterated: “Forefront RF’s breakthrough technology addresses key technological challenges in an ever-more connected world, while also delivering environmental benefits. Supporting businesses as they transition from start-up to maturity is a fundamental part of BGF’s mission, and it’s immensely rewarding to back such an innovative British business as it develops world-leading technology.”
