Testimonials from Cohort #1 Startup Companies
MintNeuro - Dorian Haci, CEO
Dorian Haci, CEO and co-founder of MintNeuro, says “access to multiple licenses of Electronic Design Automation tools at no cost and free prototype runs with TSMC, the leading foundry in the world, is accelerating our go to market plan. The training, advice and support from some of the best semiconductor experts in the world today is significantly mitigating our risks to deliver our high quality implantable medical devices for neural stimulation of the brain much faster than we thought possible. This fully funded UK Government ChipStart UK incubation, delivered by SiliconCatalyst.UK, is providing a clear path to our initial seed investment. It is providing demonstrable risk reduction in every aspect of our business plan.”
Vaire - Rodolfo Rosini, CEO and co-founder
Vaire is the first chip company in the world to deliver on the promise of near zero energy AI compute. “We have made connections into the global semiconductor industry that would have been near impossible without the help of SiliconCatalyst.UK delivering this fantastic ChipStart UK incubation programme”, said Rodolfo Rosini, CEO and co-founder.
BlueShift Memory - Helen Duncan, CEO
Helen Duncan, Chief Executive Officer for BlueShift Memory, said “The training and advice we have received from the Silicon Catalyst ecosystem has helped us sharpen our value proposition and go to market strategy. Putting us on the ChipStart UK stage has enabled us to attract the right investors at the right time, and we believe it has provided a springboard for our future success.”
HyperCIM - Tanya Mangoma, CEO and founder
Tanya Mangoma, CEO and founder of HyperCIM, said “to have a founder of Arm, Jamie Urquhart, as our ChipStart UK personal Mentor is gold dust. We are absolutely delighted to be one of the chosen few to be allowed to drink from the fire hydrant of global semiconductor opportunity that SiliconCatalyst.UK is pouring into us with this fabulous fully UK Government funded incubator”.
RED Semiconductor - James Lewis, CEO
James Lewis, CEO of RED Semiconductor, said “winning a coveted place on the ChipStart UK semiconductor startup incubator delivered by SiliconCatalyst.UK has been pivotal for our go to market strategy. The semiconductor industry specific deep dive training has refined our business plan. The global market leading customers and partner opportunities that Silicon Catalyst has delivered to us are game changing.”
Singular Photonics - Shahida Imani, CEO and co-founder
“The Silicon Catalyst ecosystem delivered through the superb ChipStart UK semiconductor startup incubator has been of immense support during our spin-out process from Edinburgh University,” said CEO and co-founder of Singular Photonics, Shahida Imani. “Their In-Kind Partners have provided free EDA tools and access to advanced TSMC foundry runs. Their advisers have built mutual respect and trust up and down the supply chains that we need to build our business in, and their deep knowledge and advice has been seminal to attract our first pre-seed investment.”
Current ChipStart UK Companies (Cohort #3)
Managed by SiliconCatalyst.UK
Chipletti is a UK-based fabless semiconductor design company focused on advancing AI inference performance through innovative 3D memory solutions. We develop memory chiplets and licensable interconnect IP that enables cost-effective 3D stacking, allowing AI hardware companies to expand memory capacity without significantly increasing power consumption. Our technology targets the critical metric of performance per watt per mm², addressing memory bottlenecks in high-performance, energy-efficient AI systems.
From Defence to Datacenter, Ethicronics develops low-level software to secure data-in-use and data-at-rest — starting with hardware assurance for defence/critical infrastructures.
Our non-destructive, universally applicable solution, currently in development, delivers 100% assurance across chips and boards, guaranteeing hardware authenticity without sampling or destructive testing.
By reducing assurance costs and bringing nanometre-level integrity/authenticity certificates, Ethicronics helps primes and government buyers avoid multimillion-dollar breaches, critical failures and secure strategic advantage in high-stakes environments.
We develop unique bioelectronic chip-based devices to measure trace chemicals in water and other liquids. Our devices provide real-time, quantitative measurements of target chemical concentration for environmental, industrial and biomedical liquid diagnostics in a form-factor that can be integrated with any conventional electronic system. By using bioengineered micro-organisms coupled to novel silicon chips, we can develop sensitivity to a diverse range of natural and synthetic chemical targets, including those which cannot be detected currently by existing technology.
Kelvin Quantum is a fabless design house for development of semiconducting circuits and full electronic systems capable of operating within cryogenic environments alongside growing quantum technologies. Kelvin Quantum systems allow quantum technology providers to scale up their technologies and bring them to market.
Computer vision-mediated AI is revolutionising a wide range of industries but is constrained by the simplistic data acquired when conventional cameras capture light. Prospectral is building optical chips and computer vision software that allow for cameras which capture extra dimensions of data from light. This data enables previously “invisible” insights in industries like mining (on-site material analysis), manufacturing (contamination, defect detection) and autonomous systems for robotics or automotive (enhanced classification and detection of surroundings).
Quantopticon has developed a unique, patent-protected simulation platform, Quantillion, that fundamentally transforms the design workflow for quantum-photonic devices. By enabling engineers and researchers to validate device architectures virtually “right-first-time”, Quantillion dramatically reduces both the cost and development time traditionally associated with iterative hardware prototyping. This streamlined approach accelerates the broader digital transition within the quantum technology sector, facilitating the creation of integrable, scalable components suitable for a wide range of high-impact applications – from ultra-secure communication networks to next-generation position, navigation and timing systems.
AI's growth faces two key roadblocks: energy consumption and data availability, ultimately restricting AI deployment. At Rayd Technologies, we are revolutionising the way computation is performed with a brain-inspired photonic computing hardware and accompanying algorithms. Our system offers orders of magnitude improvements in throughput and energy consumption for machine vision, and trains with up to 10X less data, enabling advanced AI models to be rapidly deployed at the edge.
RX Watt provides a leading solution for long-range RF wireless power transfer, combined with communication and RF sensing capabilities. This enables battery-free sensing in harsh industrial environments and low-cost, sustainable tags for logistics and supply chain. This is enabled by a scalable CMOS solution for high-sensitivity power reception and low-power communication.
SiDesign Works is an Oxford-based semiconductor startup creating the chips that power the future of satellite communications. Our designs enable smarter, more efficient antennas that connect people and systems anywhere on Earth and in space. We make connectivity faster, more reliable, and ready for the next generation of networks.
As a spin-out from the University of Southampton, Smith Optical is commercializing a breakthrough AR display technology called Wavemixing. Our patented approach delivers the industry's first 100% transparent, daylight-bright displays with true 3D depth and zero eye-glow. We are building the foundational display component that will enable the mass adoption of AR smart glasses.
Xen Quantum is building technology to make quantum communications more practical.
