London Tech Week 2026: AI, Quantum and the UK’s Deep Tech Investment

Our Innovation Consultants Claudia and Naoki spent time at London Tech Week 2026 attending sessions across AI, deep tech investment and quantum computing. What they found was a market in the middle of a genuine structural shift. These are the insights that stood out.

The UK Has Earned Its Place at the Top Table

The evidence was clear this year. The UK now hosts over 2,500 venture-backed AI startups, with AI accounting for roughly one third of total UK tech value, up from just 13% in 2021. UK AI startups have already raised more than $11 billion this year, a new annual record reached within six months. Three in four UK venture pounds are now going into AI and the UK is capturing around one third of all European investment – roughly equal to Germany and France combined.

Beyond AI, the UK is second only to the US for quantum startups. A recent quantum funding round of £160 million was cited as record-breaking and oversubscribed.

Key takeaway: The UK is no longer positioning itself as a rising tech nation. If your organisation is operating in AI or deep tech, the ecosystem around you is stronger than it has ever been with funding opportunities to match.

Investors Are More Selective Than Ever

Founder quality is the deciding factor. Investors noted that UK founders have become significantly more ambitious over the last decade, with unicorn success stories shifting what people believe is possible. The data reflects this:

• 30% of founders say their business wouldn’t exist without AI
• More than 60% say it’s critical to their model or scaling

But the bar has risen sharply. Generic AI companies built on top of existing models without genuine differentiation are no longer attracting serious capital. Even businesses with strong revenue and growth can struggle to raise if they lack defensible IP.

Key takeaway: If you are building in AI, your differentiation story is everything. Investors are backing globally minded, resilient teams with deep technical insight, not products that could be replicated by a competitor.

Platform Dependence Is a Real and Growing Risk

One in four founders are changing strategy because of major AI platform dominance. Thirty percent are actively building their own tools to reduce that dependence. The economic reality is striking: for every £1 of AI-attributed exit value created in the UK, 50-70p flows to the US. Only 9p stays here.

Key takeaway: Platform risk is no longer a theoretical concern. If your product relies heavily on a single AI provider, now is the time to think about how you build resilience and long-term defensibility into your model.

Quantum: Start Preparing Now, Not Later

The quantum sessions delivered a consistent message: this is no longer a science project. It is an industrial opportunity that requires serious preparation today.

The UK’s ambition is quantum at scale by the early 2030s, with some speakers suggesting meaningful technical advantage could arrive within three to four years. But the panel was clear that lab breakthroughs alone won’t determine who wins. Quantum leadership requires customers, procurement, engineering talent and scale-up capital.

The sectors best placed for early quantum advantage are financial services, life sciences and pharmaceuticals and automotive, where use cases in optimisation, simulation and molecular discovery are already well-defined. For corporates in these sectors, the advice was direct: quantum is still early, but it is not too early to act. Identify your use cases, build internal literacy and form selective partnerships now.

Key takeaway: Waiting for certainty means falling behind. The organisations gaining ground in quantum right now are the ones engaging with the ecosystem, not the ones watching from the sidelines.

Funding Opportunities Closing Soon

If the quantum opportunity is relevant to your organisation, there are two significant funding competitions open right now that are worth acting on quickly.

Scaling Supply Chains for Quantum Enabled Sensing and PNT

Closes: 8 July 2026

UK registered organisations can apply for a share of up to £32.8 million for collaborations developing the supply chain for quantum enabled sensing. This competition is funded by Innovate UK and is open to collaborations led by a UK registered business of any size, with at least one SME in the consortium claiming grant funding.

The Bigger Picture for Innovation-Led Businesses

The UK is a serious deep tech ecosystem and the competitive window to build defensible positions in AI and quantum is narrowing. Generic approaches are losing investor appeal. Differentiation, IP and founder quality are what counts. The organisations that will capture value from this wave are the ones preparing seriously today.

Interested in applying but not sure where to start? Get in touch with PNO, we support organisations from positioning, to writing through to grant compliance.
