ChipStart UK Startups Gaining Momentum as Programme Graduates 3rd Cohort and Launches 4th Cohort with Government Backing

LONDON, 19th March 2026 - ChipStart UK launched its fourth cohort of semiconductor startups at The Royal Institution, with Minister Kanishka Narayan MP from the Department of Science, Innovation and Technology (DSIT) delivering a video keynote to a registered audience of more than 200 industry delegates, including over 30 venture capital hardtech investors.

Across its first three cohorts, ChipStart UK alumni companies have now raised close to $100M in equity funding. Twelve new companies were selected from 42 applications to join the fourth cohort of the fully-funded, 12-month incubation programme, with applications up more than 50% and event attendance up 30% year-on-year.

Minister Narayan, who has spent a decade on the front line of technology investment across the UK and beyond, outlined the government’s commitment to the UK’s semiconductor ecosystem. DSIT is backing the sector with a £100M Advanced Market Commitment to purchase products from novel and promising UK chip companies, alongside over £6.5M to uplift university research infrastructure across the country.

Outlining the government's broader ambition for UK technology entrepreneurship, the Minister said: “At the heart of this change is embracing a culture that prizes innovation, that says to entrepreneurs that their success is our national success, that their companies are our national champions when they create jobs and invest in frontier innovation here.” He described ChipStart UK as an important part of that shift, adding: “ChipStart is about giving startups the best possible chance to succeed, the tools to take those risks.”

Moshe Gavrielov, former CEO of Xilinx and current board member of TSMC, NXP Semiconductors and Cadence Design Systems, delivered a keynote on where the industry is heading: custom silicon making a comeback, AI cutting design costs by 30-80%, and power efficiency becoming the defining challenge of the age.

Gavrielov later joined Jalal Bagherli CBE and Rodolfo Rosini on an expert panel chaired by Nitin Dahad, editor-in-chief of EE Times, to explore whether the semiconductor industry's future lies solely in AI or in a much broader set of opportunities.  The consensus which emerged was that the industry focuses solely on AI at its peril.

The ChipStart UK programme is led by Sean Redmond, Russell Haggar and Ross Addinall of Silicon Catalyst.UK.

Russell Haggar, Managing Partner of Silicon Catalyst.UK,  commented:

“It is so exciting to see the ChipStart UK programme growing so strongly.  We are starting to see a renaissance of strong semiconductor startups in the UK, building on the talent and experience of our industry, and the innovation of our research base. Our graduating cohort of 12 fantastic startups did themselves proud in presenting at such a prestigious venue for science and innovation.  They have been a real pleasure to work with over the past twelve months, and it has been so rewarding to watch them develop.  We are now looking forward to start working with our next group of ambitious startups, equipping them with the tools and experience needed to fulfill their goals.”

Cohort #4: The Twelve Companies

Twelve companies were selected to join the programme, spanning quantum computing, photonics, AI processing, biosensing, satellite communications, and biotech manufacturing. Nearly half of the twelve companies are founded or co-founded by women.

• ABACQuS — Novel quantum processor using arsenic dopants in silicon, with full connectivity and modular error correction

• Altro Photonics — UCL spinout developing optical transceivers for AI data centres and quantum photonics

• Analogue Opto — Tackling the LLM memory bottleneck with optical disaggregated memory architecture

• Atlas Processing — Hardware memory and computation fabric eliminating GPU idle time for AI inference, targeting hyperscaler deployment

• Compound Hound — Electronic nose technology reading 280+ compounds, with initial focus on food supply chain spoilage monitoring

• Hyperspace AI — Ultra-low-latency, power-efficient chips for human-machine interaction

• Nibras Communications — Light-based signal generation for satellite communications, covering 1–300 GHz from a single module

• Orbicom — 3D-stacked photonic chips achieving 145 GHz bandwidth and total cost of ownership reduction for AI data centres

• Qascade — Scalable indium arsenide semiconductor qubits capable of tens of thousands of qubits per chip

• RobQuant — Room-temperature solid-state quantum sensors

• Skoosh — Real-time biopharmaceutical production monitoring

• TrackStar — Silicon photonics-based eye tracking for the smart glasses market

Cohort #3 Graduation

The event celebrated the graduation of Cohort #3: Smith Displays, Prospectral, SiDesign Works, Ethicronics, Chipletti, Rayd Technologies, RX Watt, quadrAI, Quantopticon, Kāhu SiliconBio, Xen Quantum and Kelvin Quantum.

Previous graduate Wave Photonics from ChipStart UK’s first cohort also presented at the event.  A large number of graduates from the first three cohorts attended the event in the audience.
